Background and aim: Removing the chest tube in cardiac patients after surgery is one of the worst experiences of hospitalization in the intensive care units. Various pharmacological and non-pharmacological methods are available to control pain in these patients. This study aimed to investigate the combined effect of reflexology massage and respiratory relaxation on pain following chest tube removal in cardiac surgery patients of Shahid Beheshti Hospital in Shiraz, Iran, in 2023. Methods: This was a double-blind randomized clinical trial performed on 140 patients who underwent heart surgery and had a chest tube in Shiraz, Iran. The samples were randomly divided into four groups: 1- control group, 2- respiratory relaxation group, 3- foot reflex massage group, and 4- a combination of respiratory relaxation and reflexology massage. To collect data, two demographic questionnaires, and a visual analog scale were used. Results: The participants of the four groups were not meaningfully different in terms of age, BMI, duration of surgical operation, gender, job, education, place of residency, number of chest tubes, history of operation (P = 0.99, 0.31, 0.06, 0.81, 0.97, 0.96, 0.17, 0.10, 0.89 respectively). The mean scores of pain intensity during chest tube removal, and 15 min after chest tube removal were not statistically different among the four groups of study (P = 0.15, 0.54 respectively); However, just after chest tube removal, the mean scores of pain intensity differed meaningfully among four groups (P = 0.008). Conclusion: The results showed that reflexology massage and respiratory relaxation both reduce pain immediately after chest tube removal in heart surgery patients. Also, the combination of these two techniques was more effective in reducing patients' average pain. [ABSTRACT FROM AUTHOR]

Objectives: In patients with left heart disease and severe aortic stenosis (AS), pulmonary hypertension (PH) is a common comorbidity and predictor of poor prognosis. Untreated AS aggravates PH leading to an increased right ventricular afterload and, in line to right ventricular dysfunction. The surgical benefit of aortic valve replacement (AVR) in elderly patients with severe AS and PH could be limited due to the multiple comorbidities and poor outcomes. Therefore, we purposed to investigate the impact of PH on short-term outcomes in patients with moderate to severe AS who underwent surgical AVR in our heart center. Methods: In this study we retrospectively analyzed a cohort of 99 patients with severe secondary post-capillary PH who underwent surgical AVR (AVR + PH group) at our heart center between 2010 and 2021 with a regard to perioperative outcomes. In order to investigate the impact of PH on short-term outcomes, the control group of 99 patients without pulmonary hypertension who underwent surgical AVR (AVR group) at our heart center with similar risk profile was accordingly analyzed regarding pre-, intra- and postoperative data. Results: Atrial fibrillation occurred significantly more often (p =.013) in patients who suffered from PH undergoing AVR. In addition, the risk for cardiac surgery (EUROSCORE II) was significantly higher (p <.001) in the above-mentioned group. Likewise, cardiopulmonary bypass time (p =.018), aortic cross-clamp time (p =.008) and average operation time (p =.009) were significantly longer in the AVR + PH group. Furthermore, the in-hospital survival rate was significantly higher (p =.044) in the AVR group compared to the AVR + PH group. Moreover, the dialysis rate was significantly higher (p <.001) postoperatively in patients who suffered PH compared to the patients without PH undergoing AVR. Conclusion: In our study, patients with severe PH and severe symptomatic AS who underwent surgical aortic valve replacement showed adverse short-term outcomes compared to patients without PH.

Children's autonomy includes, as far as possible, self-determination, bodily integrity and the right to influence outcomes. Limits to bodily integrity, which involves no touching without the child's consent or tacit agreement, are discussed. The clinical, legal and ethics literature tends to agree that children may give valid consent to major recommended treatment from around 12 years but may not refuse it until they are legal adults. Research shows that young children are more aware of their bodily integrity and autonomy, of morality and decision making, than was assumed in the past. Adults therefore need to inform children and respect their initially instinctive efforts to protect their bodily integrity. Unlike assent, consent involves patients being adequately informed and being able to accept or refuse proposed treatment. Reasons are given for adults' need to consult with children when determining their best interests. Beyond words, giving or withholding consent also involves emotions of fear, trust and courage, besides embodied reactions of cooperating with treatment or resisting it, in which young children actively engage. Some clinicians work with the informed cooperation of young children who need lifesaving treatment, and at times accept their refusal. Reasons for differences between mainstream experts' views and clinical practices are considered. [ABSTRACT FROM AUTHOR]

Beating-heart surgery is performed to reduce patient trauma but depending on the intervention requires tissue stabilization through vacuum cardiac tissue stabilizers. Current designs either require open chest sternotomy or display significant residual motion when used minimally invasively. Active motion compensation methods require complex control algorithms and expensive technology. We propose a novel design for a vacuum tissue stabilizer with expandable suction feet enabling a larger stabilized area and increased motion reduction. Its performance is evaluated on a heart phantom using a silicon membrane mimicking cardiac tissue properties. The motion of the membrane is captured using a stereo camera and marker points on the membrane surface. The results are then compared to a state-of-the-art tissue stabilizer. The extended stabilizer is found to stabilize a 110% larger area while achieving similar motion amplitude reduction. Thus, extendable stabilizers seem to be a promising solution for improved cardiac tissue stabilization in less invasive beating-heart surgery. [ABSTRACT FROM AUTHOR]

Background & aim: Inadequate myocardial protection and intraoperative myocardial injury (PMI) are important and common complications in various cardiac surgical procedures. Therefore, the aim of the present study was to determine and investigate the effect of preoperative nicorandil on myocardial injury after open heart surgery. Methods: The present single-blinded clinical trial analysis study was conducted in 2023 at Shahid Chamran Educational and Medical Center - Isfahan. The participants were 70 patients (35 in each group) who were randomly assigned to two control and intervention groups for cardiac surgery. Based on the computer-based randomization, they were divided into two intervention and control groups. In the intervention group, in addition to the usual treatments, oral nicorandil tablets were administered at a dose of 10 mg 3 times. The patients were anesthetized in a similar way and operated by a team. After surgery, the patients were evaluated and compared in terms of clinical criteria including troponin eight and twenty-four hours after surgery, the anatomy of the patient's coronary arteries after counting, the duration of hospitalization in the ICU, the time required for mechanical ventilation (ventilator), the occurrence of myocardial infarction, the occurrence of new arrhythmia, the need for the use of intra-aortic balloon pump (IABP), and mortality in the two groups. The collected data were analyzed using t-test, chi-square, Wilcoxon, and Mann-Whitney statistical tests. Results: The results indicated that in the control group, 11.4% were female and 88.6% were male, with an average age 58.42±8.46 years, and in the intervention group, 42.9% were female and 57.1% were male with The average age 59.31± 6.88 years. Also, 50% of the people participating in the study were in the age range of 60-70 years). Respectively the average EF in the control group was 54.42±8.43. At 8 hours and 24 hours after the operation, troponin in the intervention group (1.36±0.8 and 1.56±0.83) was significantly higher than the control group (2.06±0.75 and 2.44±0.91 (p

Abstract Background This study explores the factors contributing to the occurrence of delirium following cardiac surgery and devises nursing strategies rooted in behavior change theory. Methods A cohort of 320 cardiac surgery patients was selected, categorized into two groups: 93 cases where postoperative delirium (POD) was anticipated, and 227 cases where it was not. Preoperative, intraoperative, and postoperative factors of POD were scrutinized using single-factor analysis, while binary logistic regression analysis was employed to pinpoint risk factors. Results Among the 320 patients, 93 displayed POD symptoms post-surgery, yielding an incidence of 29.06%. Preoperative univariate analysis disclosed significant differences in gender, age, smoking, hypertension, and diabetes (P

Introduction This study aimed to systematically analyze and describe the main challenges of congenital heart diseases (CHDs) in the countries in the Amazon region. Methods The methodology followed the Preferred Reporting Items for Systematic Reviews and Meta-Analyses extension for Scoping Reviews checklist utilizing the Medline, Embase, Lilacs, and Google Scholar databases. The inclusion criteria were articles addressing any topic involving CHD in the Amazon region. Incomplete articles, book chapters, lectures, conference abstracts, and editorials were excluded. Results Nine studies were identified, 7 of which were published in the last decade and were of Colombian and Brazilian origin. The methodology of the studies was cross-sectional and ecological, evaluating the regional and epidemiological factors, challenges to diagnosis and treatment, multidisciplinary team challenges, and the impact of the COVID-19 pandemic. Studies carried out by surgeons demonstrate more existing data regarding the challenges of the health-care system. Conclusions There is growing interest in analyzing the situation of CHD in the region. However, only a few studies are available, mostly on ecological and cross-sectional analysis. These records show the lack of hospital infrastructure and multidisciplinary teams for the diagnosis and treatment of CHD in the Amazon region; we see an initiative by specialists from two countries (Colombia and Brazil) to demonstrate the difficulties by seeking international training programs and government aid to improve the health system situation.

ABSTRACT Introduction Methods Results Conclusions Estimating patient risk before heart surgery (HS) is crucial. Perioperative inflammation is associated with several complications and mortality. This study investigated blood cell count inflammatory indices (BCCII) to predict risks, including neutrophil‐to‐lymphocyte ratio (NLR), derivate NLR (DNLR), neutrophil‐to‐platelet‐lymphocyte ratio (NLPR), lymphocyte‐to‐monocyte ratio, platelet‐to‐lymphocyte ratio (PLR), Systemic Inflammatory Index (SII), Systemic Inflammatory Reaction Index (SIRI), and Aggregate Index of Systemic Inflammation (AISI).Data from a cohort of patients undergoing on‐pump HS at a single center in Brazil were retrospectively analyzed. Data were obtained from medical records and a laboratory analyzer, and SPSS version 20.0 was used for index calculations and statistical analyses.In total, 444 surgeries were performed, and 40 in‐hospital deaths occurred. Except for PLR, all other indexes were independent predictors of death after multivariate adjustment (all p < 0.05). Discrimination performance was absent for PLR and AISI, and NLR, NLPR, and DNLR demonstrated the best area under the receiver operating characteristic curve (AUC > 0.7; all p < 0.0001). For survivors (n = 404), all indexes exhibited a correlation with the length of hospital stay (all p < 0.03), and NLR, NLPR, and DNLR were predictors (p < 0.026) of poor operative outcomes (acute myocardial infarction, cerebrovascular attack, cardiac arrest, low cardiac output, prolonged mechanical ventilation, renal failure, and sepsis).All BCCII scores were associated with length of hospital stay. Apart from PLR, all indexes were independent predictors of in‐hospital mortality. Accuracy was highest for NLR, NLPR, and DNLR; for survivors, these three factors were good predictors of poor operative outcomes. [ABSTRACT FROM AUTHOR]

Background: This study explores the factors contributing to the occurrence of delirium following cardiac surgery and devises nursing strategies rooted in behavior change theory. Methods: A cohort of 320 cardiac surgery patients was selected, categorized into two groups: 93 cases where postoperative delirium (POD) was anticipated, and 227 cases where it was not. Preoperative, intraoperative, and postoperative factors of POD were scrutinized using single-factor analysis, while binary logistic regression analysis was employed to pinpoint risk factors. Results: Among the 320 patients, 93 displayed POD symptoms post-surgery, yielding an incidence of 29.06%. Preoperative univariate analysis disclosed significant differences in gender, age, smoking, hypertension, and diabetes (P < 0.05). Intraoperatively, significant differences were noted in the American Society of Anesthesiologists (ASA) anesthesia grade (II, III, and IV), surgery time, cardiopulmonary bypass duration, and aortic occlusion duration (P < 0.05). Post-surgery, significant differences were observed in the duration of Intensive Care Unit (ICU) stay, mechanical ventilation time, and visual analogue scale (VAS) scores (P < 0.05). Multivariate Logistic regression identified surgery time (OR = 2.334, P < 0.001), ICU admission duration (OR = 1.457, P < 0.001), mechanical ventilation time (OR = 1.235, P = 0.004), and VAS scores (OR = 2.986, P < 0.001) as independent risk factors for POD. ROC curve analysis indicated higher sensitivity and specificity in predicting POD with surgery time, ICU stay duration, mechanical ventilation time, and VAS scores. Conclusion: Irrespective of the surgical intervention type, surgery time, ICU stay duration, mechanical ventilation time, and VAS scores are recognized as risk factors for POD in cardiac surgery patients. Hence, continuous patient monitoring and early intervention tailored to specific risk factors are essential in clinical practice to mitigate POD incidence. [ABSTRACT FROM AUTHOR]

Summary: Sleep‐disordered breathing is common in patients with coronary artery disease undergoing coronary artery bypass grafting. Sleep‐disordered breathing is associated with increased perioperative morbidity, arrhythmias (e.g. atrial fibrillation) and mortality. This study investigated the impact of sleep‐disordered breathing on the postoperative course after coronary artery bypass grafting, including development of atrial fibrillation. This prospective single‐centre cohort study included adults undergoing coronary artery bypass grafting. All were screened for sleep‐disordered breathing (polygraphy) and atrial fibrillation (electrocardiogram) preoperatively; those with known sleep‐disordered breathing or atrial fibrillation were excluded. Endpoints included new‐onset atrial fibrillation, duration of mechanical ventilation, time in the intensive care unit, and postoperative infection. Regression analysis was performed to identify associations between sleep‐disordered breathing and these outcomes. A total of 508 participants were included (80% male, median age 68 years). The prevalence of any (apnea–hypopnea index ≥ 5 per hr), moderate (apnea–hypopnea index = 15–30 per hr) and severe (apnea–hypopnea index > 30 per hr) sleep‐disordered breathing was 52.9%, 9.3% and 10.2%, respectively. All‐cause 30‐day mortality was 0.98%. After adjustment for age and sex, severe sleep‐disordered breathing was associated with longer respiratory ventilation support (crude odds ratio [95% confidence interval] 5.28 [2.18–12.77]; p < 0.001) and higher postoperative infection rates (crude odds ratio 3.32 [1.45–7.58]; p < 0.005), but not new‐onset atrial fibrillation or mortality. New‐onset atrial fibrillation was significantly associated with postoperative infection and prolonged hospital stay. The significant associations between sleep‐disordered breathing and several adverse outcomes after coronary artery bypass grafting support the need for preoperative sleep‐disordered breathing screening in individuals undergoing cardiac surgery.

Background: In-hospital mortality and complication rates after partial and radical nephrectomy in patients with history of heart-valve replacement are unknown. Patients and Methods: Relying on the National Inpatient Sample (2000–2019), kidney cancer patients undergoing partial or radical nephrectomy were stratified according to presence or absence of heart-valve replacement. Multivariable logistic and Poisson regression models addressed adverse hospital outcomes. Results: Overall, 39,673 patients underwent partial nephrectomy versus 94,890 radical nephrectomy. Of those, 248 (0.6%) and 676 (0.7%) had a history of heart-valve replacement. Heart-valve replacement patients were older (median partial nephrectomy 69 versus 60 years; radical nephrectomy 71 versus 63 years), and more frequently exhibited Charlson comorbidity index ≥ 3 (partial nephrectomy 22 versus 12%; radical nephrectomy 32 versus 23%). In partial nephrectomy patients, history of heart-valve replacement increased the risk of cardiac complications [odds ratio (OR) 4.33; p < 0.001), blood transfusions (OR 2.00; p < 0.001), intraoperative complications (OR 1.53; p = 0.03), and longer hospital stay [rate ratio (RR) 1.25; p < 0.001], but not in-hospital mortality (p = 0.5). In radical nephrectomy patients, history of heart-valve replacement increased risk of postoperative bleeding (OR 4.13; p < 0.001), cardiac complications (OR 2.72; p < 0.001), intraoperative complications (OR 1.53; p < 0.001), blood transfusions (OR 1.27; p = 0.02), and longer hospital stay (RR 1.12; p < 0.001), but not in-hospital mortality (p = 0.5). Conclusions: History of heart-valve replacement independently predicted four of twelve adverse outcomes in partial nephrectomy and five of twelve adverse outcomes in radical nephrectomy patients including intraoperative and cardiac complications, blood transfusions, and longer hospital stay. Conversely, no statistically significant differences were observed in in-hospital mortality. [ABSTRACT FROM AUTHOR]

Abstract Objective The impact of nitric oxide (NO) administered via cardiopulmonary bypass (CPB) on pediatric heart surgery remains controversial. The objective of this study is to conduct a comprehensive systematic review and meta-analysis to examine the impact of NO administered via CPB on pediatric heart surgery. Methods This study searched 7 electronic databases to identify Randomized Controlled Trials (RCTs) on the impact of NO administration during CPB on postoperative outcomes in pediatric heart surgery. The searched databases included Embase, Medline (though PubMed), Cochrane Library, Web of Science, Wan Fang database, China National Knowledge Infrastructure (CNKI), and ClinicalTrials.gov from their inception to November 2, 2022. The included RCTs compared NO administration during CPB with standard CPB procedures or placebo gas treatment in pediatric heart surgery. fixed-effects models and/or random-effects models were used to estimate the effect size with 95% confidence interval (CI). Heterogeneity among studies was indicated by p-values and I2. All analyses were performed using Review Manager software (version 5.4) in this study. Results A total of 6 RCTs including 1,739 children were identified in this study. The primary outcome was duration of postoperative mechanical ventilation, with the length of hospital and intensive care unit (ICU) stay as the second outcomes. Through a pooled analysis, we found that exogenous NO administered via CPB for pediatric heart surgery could not shorten the duration of postoperative mechanical ventilation when compared with the control group (standardized mean difference (SMD) -0.07, CI [–0.16, 0.02], I2 = 45%, P = 0.15). Additionally, there were also no difference between the two groups in terms of length of hospital stay (mean difference (MD) -0.29, CI [–1.03, 0.46], I2 = 32%, P = 0.45) and length of ICU stay (MD -0.22, CI [–0.49 to 0.05], I2 = 72%, P = 0.10). Conclusions This meta-analysis showed that exogenous NO administration via CBP had no benefits on the duration of mechanical ventilation, the length of postoperative hospital, and ICU stay after pediatric heart surgery.

Objective: Left atrial appendage closure (LAAC) concomitant to heart surgery in patients with underlying atrial fibrillation (AF) has gained attention because of long-term reduction of thromboembolic complications. As of mortality benefits in the setting of non-AF, data from both observational studies and randomized controlled trials are conflicting. Methods: On-line databases were screened for studies comparing LAAC versus no LAAC concomitant to other heart surgery. End points assessed were all-cause mortality and stroke at early and longest-available follow-up. Subgroup analyses stratified on preoperative AF were performed. Risk ratios (RR) with 95% CIs served as primary statistics. Results: Electronic search yielded 25 studies (N = 660 [158 patients]). There was no difference between LAAC and no LAAC in terms of early mortality. In the overall population analysis, LAAC reduced long-term mortality (RR, 0.86; 95% CI, 0.74-1.00; P = .05; I2 = 88%), reduced early stroke risk by 19% (RR, 0.81; 95% CI, 0.72-0.93; P = .002; I2 = 57%), and reduced late stroke risk by 13% (RR, 0.87; 95% CI, 0.84-0.90; P

Abstract Background Pseudoaneurysm of the mitral-aortic intervalvular fibrosa (PMAIF) is a rare complication of infective endocarditis or aortic valve surgery. Surgical treatment is suggested, but the long-term follow-up of conservative management remains unclear. Case presentation A 33-year follow-up of a patient who developed PMAIF six years after aortic valve replacement is reported. The patient presented to our center with dyspnea, and the echocardiography revealed an ejection fraction of 20% and a PMAIF measuring 7 × 10 mm. Despite being advised to undergo surgery, the patient declined due to fear of surgical outcomes. Consequently, conservative treatment with close observation but without surgery was initiated. During the 33-year follow-up period, the patient did not experience any adverse health effects. Conclusion Surgical intervention should be considered whenever the PMAIF is diagnosed. However, in any case that the surgery was not applicable, conservative management might lead to long-term survival, based on this and similar case reports in the literature.

Aim: This nationwide study evaluated the clinical impact that an early thymectomy, during congenital heart defect (CHD) surgery, had on the health of children and adolescents. Methods: The subjects were patients aged 1–15 years who had undergone CHD surgery at the University Children's Hospital, Helsinki, where all CHD surgery in Finland is carried out, from 2006 to 2018. The parents or the cases and population‐based controls, matched for sex, age and hospital district, completed electronic questionnaires. We excluded those with low birth weights or a known immunodeficiency. Adjusted odds ratios (aOR) and 95% confidence intervals (CI) were calculated for prespecified outcomes. Results: We received responses relating to 260/450 (58%) cases and 1403/4500 (31%) controls and excluded 73 cases with persistent cardiac or respiratory complaints after surgery. The CHD group reported more recurrent hospitalisations due to infections (aOR 6.3, 95% CI 3.0–13) than the controls and more pneumonia episodes (aOR 3.5, 95% CI 2.1–5.6), asthma (aOR 2.5, 95% CI 1.5–4.1) and wheezing (aOR 2.1, 95% CI 1.5–2.9). Conclusion: Hospitalisation due to infections, pneumonia, wheezing and asthma was more common in children after a thymectomy due to open‐heart surgery than population‐based controls, underlining the importance of immunological follow‐ups.

Background: The management of heart surgery waiting list is essential, particularly in ultraperipheral regions. We aimed to characterise a cohort of patients awaiting surgery in such a region, and to assess the occurrence of adverse events and causative factors. Methods: A retrospective, multicentre analysis from 2016 to 2020. Patients were divided into "Urgent group" vs "Priority group" based on surgical priority. A composite outcome of death or hospital admission was determined. Results: We included 329 patients, 18.2% in the Urgent group. Baseline characteristics were similar, except for a higher prevalence of smoking habits in the Urgent group (56.7% vs 38.7%, p = 0.016), as well as the CCS class (p = 0.014) and EuroScore surgical risk (p < 0.001). Disease acuity indicated highest priority for coronary artery bypass grafting patients. Myocardial revascularization and aortic valvular replacement were the main procedures. Overall, 15.2% of patients received treatment within recommended waiting time, with 50.8% being Urgent patients. Urgent patients had higher risk for composite outcome (HR 3.92, 95% CI 1.26-12.22; p = 0.019), with fewer events reported (5% vs 17.8%, p = 0.051). Chronic kidney disease and previous open-heart surgery were independent predictors of this outcome. Chronic kidney disease remained as independent predictor at 1-year follow-up, while surgical priority did not affect outcomes. Conclusions: Despite similar occurrences of adverse events on the waiting list, longer waiting times for patients in the Urgent group increase their risk of adverse events. The priority level had no impact on outcomes. Chronic kidney disease and open-heart surgery were independent predictors for events, highlighting their significance in the triage process.

Introduction: Neurological impairment is a big concern in the development of patients with congenital heart defects (CHD). A number of neuromarkers have been studied in search of a diagnostic or prognostic marker for brain injury during the vulnerable perioperative period. Our aim was to assess two novel neuromarkers, myelin basic protein (MBP) and protein Tau (pTau), as diagnostic markers for brain injury in perioperative period in children with CHD. Methods: Forty patients were enrolled and dichotomized based on peripheric oxygen saturation in cyanotic and non-cyanotic group. Blood samples were collected preoperative, after the induction of anesthesia, and in postoperative day 1. Neuromarker concentrations were measured using commercially available ELISA kits. Results: Neuromarkers' values were increased postoperative, with statistical significance reached only in non-cyanotic group (p < 0.0001). A significant positive correlation was observed between preoperatory MBP and albumin level, hemoglobin level, height, and weight of patients. Association with cerebral saturations were analyzed by a coefficient defined as ≥ 20% reduction in cerebral saturation measured by near-infrared spectroscopy during perioperative period. An acceptable predicting model was observed with pTau in cyanotic group (AUC = 0.7). Conclusion: We evaluated MBP and pTau as potential biomarkers of brain injury in children with CHD undergoing cardiac surgery. Elevated postoperative pTau and MBP concentrations were observed in both groups. Elevated pTau values were associated with perioperative hypoxemia. [ABSTRACT FROM AUTHOR]

Primary cardiac tumours are relatively uncommon (75% are benign). Across the other 25%, representing malignant neoplasia, sarcomas account for 75–95%, and primary cardiac intimal sarcoma (PCIS) is one of the rarest findings. We aimed to present a comprehensive review and practical considerations from a multidisciplinary perspective with regard to the most recent published data in the specific domain of PCIS. We covered the issues of awareness amid daily practice clinical presentation to ultra-qualified management in order to achieve an adequate diagnosis and prompt intervention, also emphasizing the core role of MDM2 immunostaining and MDM2 genetic analysis. An additional base for practical points was provided by a novel on-point clinical vignette with MDM2-positive status. According to our methods (PubMed database search of full-length, English publications from January 2021 to March 2023), we identified three studies and 23 single case reports represented by 22 adults (male-to-female ratio of 1.2; male population with an average age of 53.75 years, range: 35–81; woman mean age of 55.5 years, range: 34–70) and a 4-year-old child. The tumour-related clinical picture was recognized in a matter of one day to ten months on first admission. These non-specific data (with a very low index of suspicion) included heart failure at least NYHA class II, mitral regurgitation and pulmonary hypertension, acute myocardial infarction, ischemic stroke, obstructive shock, and paroxysmal atrial fibrillation. Awareness might come from other complaints such as (most common) dyspnoea, palpitation, chest pressure, cough, asthenia, sudden fatigue, weakness, malaise, anorexia, weight loss, headache, hyperhidrosis, night sweats, and epigastric pain. Two individuals were initially misdiagnosed as having endocarditis. A history of prior treated non-cardiac malignancy was registered in 3/23 subjects. Distant metastasis as the first step of detection (n = 2/23; specifically, brain and intestinal) or during follow-up (n = 6/23; namely, intestinal, brain and bone, in two cases for each, and adrenal) required additional imagery tools (26% of the patients had distant metastasis). Transoesophageal echocardiography, computed tomography (CT), magnetic resonance imagery, and even 18F-FDG positronic emission tomography-CT (which shows hypermetabolic lesions in PCIS) represent the basis of multimodal tools of investigation. Tumour size varied from 3 cm to ≥9 cm (average largest diameter of 5.5 cm). The most frequent sites were the left atrium followed by the right ventricle and the right atrium. Post-operatory histological confirmation was provided in 20/23 cases and, upon tumour biopsy, in 3/23 of them. The post-surgery maximum free-disease interval was 8 years, the fatal outcome was at the earliest two weeks since initial admission. MDM2 analysis was provided in 7/23 subjects in terms of MDM2-positive status (two out of three subjects) at immunohistochemistry and MDM2 amplification (four out of five subjects) at genetic analysis. Additionally, another three studies addressed PCISs, and two of them offered specific MDM2/MDM2 assays (n = 35 patients with PCISs); among the provided data, we mention that one cohort (n = 20) identified a rate of 55% with regard to MDM2 amplification in intimal sarcomas, and this correlated with a myxoid pattern; another cohort (n = 15) showed that MDM2-positive had a better prognostic than MDM2-negative immunostaining. To summarize, MDM2 amplification and co-amplification, for example, with MDM4, CDK4, HMGA3, CCND3, PDGFRA, TERT, KIT, CCND3, and HDAC9, might improve the diagnosis of PCIS in addition to MDM2 immunostaining since 10–20% of these tumours are MDM2-negative. Further studies are necessary to highlight MDM2 applicability as a prognostic factor and as an element to be taken into account amid multi-layered management in an otherwise very aggressive malignancy.

AimsThe integration of smartwatches into postoperative cardiac care transforms patient monitoring, systematically tracking vital signs and delivering real-time data to a centralized platform. This study focuses on developing a platform for seamless integration, assessing reliability, and evaluating the impact on post-cardiac surgery. The goal is to establish a robust foundation for understanding the efficacy and dependability of smartwatch-based telemonitoring, enhancing care for this population.Methods and resultsA total of 108 cardiac surgery patients were divided into telemonitoring (TLM) and control (CTL) groups. The TLM group utilized smartwatches for continuous monitoring of vital parameters (SpO2, HR, BP, ECG) over 30 ± 3 days. Statistical analyses (Pearson, Intraclass Correlation, Bland-Altman, Tost Test) were employed to compare smartwatch measurements with traditional methods. Significant correlations and concordance were observed, particularly in HR and BP measurements. Challenges were noted in SpO2 measurement. The ECG algorithm exhibited substantial agreement with cardiologists (Kappa: 0.794; p > 0.001), highlighting its reliability. The telemonitoring platform played a crucial role in early detection of clinical changes, including prompt Emergency Department (ED) visits, contributing significantly to preventing outcomes that could lead to mortality, such as asymptomatic Atrioventricular block. Positive patient responses affirmed technological efficacy, especially in identifying cardiac arrhythmias like atrial fibrillation.ConclusionThe integration of smartwatches into remote telemonitoring for postoperative cardiac care demonstrates substantial potential, improving monitoring and early complication detection, thereby enhancing patient outcomes. The FAPO-X Study (Assisted Digital Telemonitoring with Wearables in Patients After Cardiovascular Surgery; NCT05966857) underscores the promising role of telemonitoring in postoperative cardiac care.

Background: Coronary artery bypass graft (CABG) surgery is a highly effective coronary artery disease treatment, providing immediate relief and promising long-term benefits. However, it is a major procedure with significant risks, including the potential for depression. Many patients experience depression following CABG, which can negatively impact their overall recovery, affecting both physical and mental health. Objective: This study aimed to determine factors predicting depression in patients following CABG surgery. Methods: This cross-sectional study was conducted with data collected between January and April 2024. A total of 272 post-CABG patients from two super tertiary care hospitals in Bangkok, Thailand, were recruited through purposive sampling. All research instruments were validated and tested for reliability. Data were analyzed using multiple regression analysis. Results: The study found that hope, optimism, illness perception, social support, and anxiety were correlated with depression (adjusted R² = 0.381), but these variables explained only 38.1% of the variance (p

Three-dimensional (3D) printing is an advanced technology for accurately understanding anatomy and supporting the successful surgical management of complex congenital heart disease (CHD). We aimed to evaluate whether our super-flexible 3D heart models could facilitate preoperative decision-making and surgical simulation for complex CHD. The super-flexible heart models were fabricated by stereolithography 3D printing of the internal and external contours of the heart from cardiac computed tomography (CT) data, followed by vacuum casting with a polyurethane material similar in elasticity to a child’s heart. Nineteen pediatric patients with complex CHD were enrolled (median age, 10 months). The primary endpoint was defined as the percentage of patients rated as “essential” on the surgeons’ postoperative 5-point Likert scale. The accuracy of the models was validated by a non-destructive method using industrial CT. The super-flexible heart models allowed detailed anatomical diagnosis and simulated surgery with incisions and sutures. Thirteen patients (68.4%) were classified as “essential” by the primary surgeons after surgery, with a 95% confidence interval of 43.4–87.4%, meeting the primary endpoint. The product error within 90% of the total external and internal surfaces was 0.54 ± 0.21 mm. The super-flexible 3D heart models are accurate, reliable, and useful tools to assist surgeons in decision-making and allow for preoperative simulation in CHD.

Background Postoperative cardiac surgery patients often experience appetite loss. Although nutritional status is known to be associated with time of recovery, functional status, and length of stay, less is known about factors related to patient’s loss of appetite after cardiac surgery. This review aimed to identify and understand factors related to loss of appetite in postoperative cardiac surgery patients, systematic review with narrative summary design was applied. Data sources including CINAHL, SCOPUS, PubMed, ProQuest, ScienceDirect, ThaiLIS, ThaiJo, and E-Thesis were searched without restriction on publication year through August 2020. Methods We conducted the review following the Joanna Briggs Institute methodology, using the Preferred Reporting Items for Systematic Reviews and Meta-analyses (PRISMA) checklist to categorize methodological quality and the PRISMA flow diagram to record the studies’ factors. Results Six studies reported one or more of 16 factors related to loss of appetite: older age, sex (female), illiteracy, history of chronic disease, not knowing someone in health field, pain score ≥ 7, pain medications containing codeine, constipation, depression, heart-lung machine ≥ 120 minutes, preoperative serum creatinine levels ≥ 179 µmol/L, emergency surgery, perfusion pressure ≤ 40 mmHg, low cardiac output syndrome, mechanical ventilation ≥ 96 hours, and a New York Heart Association class III and IV. Conclusion The small number of publications restrict our conclusions. Future research should focus on multiple factors related to appetite loss in postoperative cardiac surgery patients. Additional research will provide a foundation for evidence-based interventions to reduce appetite loss and improve patient nutritional status after cardiac surgery. Nurses and other health professionals should assess postoperative cardiac surgery patients for the presence of the 16 significant factors. To promote patients’ nutritional status, there should be evidence-based practice guidelines on the management of postoperative symptoms such as pain management, treatment of constipation, and reduction of emotional stress and depression.

Introduction: the incidence of postoperative low cardiac output syndrome is variable in the different published series, from 4% to 15%, with a mortality that approaches 20%. Although in patients over 70 years of age the syndrome may be present in up to 63%, despite the development of better cardioprotection techniques and postoperative care, the incidence of this syndrome in high-risk populations has not changed in a significant proportion. Objective: build a predictive model of postoperative low cardiac output syndrome through risk factors. Methods: an analytical study of cases and controls was carried out in patients with postoperative low cardiac output syndrome treated at the Cardiology and Cardiovascular Surgery Center of the "Saturnino Lora" Provincial Teaching Hospital of Santiago de Cuba, in a period of three years; Logistic regression with adjustments was used to obtain the model. Results: the most valuable predictive risk factors are: age >65 years, decreased right ventricular systolic function, aortic cross-clamping time and postoperative bleeding, which were those shown by the logistic regression model. Its internal validation was carried out by data division. Conclusions: the predictive model developed from logistic regression was composed of the predictors: age >65 years, decreased right ventricular systolic function, aortic clamping time >90 minutes and prolonged postoperative bleeding; It presented good fit and discriminating power, especially positive predictive value.

Cardiac pacing with temporary epicardial pacing wires (TEPW) is used to treat rhythm disturbances after cardiac surgery. Occasionally, TEPW cannot be mechanically extracted and remain in the thorax, where they may rarely cause serious complications like migration and infection. We aim to develop bioresorbable TEPW that will dissolve over time even if postoperative removal is unsuccessful. In the present study, we demonstrate a completely bioresorbable design using molybdenum (Mo) as electric conductor and the resorbable polymers poly(D, L-lactic-co-glycolic acid) (PLGA) and polycaprolactone (PCL) for electrically insulating double-coating. We compared the pacing properties of these Mo TEPW demonstrators to conventional steel TEPW in Langendorff-perfused rat hearts and observed similar functionality. In vitro , static immersion tests in simulated body fluid for up to 28 days elucidated the degradation behaviour of uncoated Mo strands and the influence of polymer coating thereon. Degradation was considerably reduced in double-coated Mo TEPW compared to the uncoated and the PLGA-coated condition. Furthermore, we confirmed good biocompatibility of Mo degradation products in the form of low cytotoxicity in cell cultures of human cardiomyocytes and cardiac fibroblasts. Temporary pacing wires are routinely implanted on the heart surface to treat rhythm disturbances in the days following cardiac surgery. Subsequently, these wires are to be removed. When removal attempts are unsuccessful, wires are cut at skin level and the remainders are left inside the chest. Retained fragments may migrate within the body or become a centre of infection. These complications may be prevented using resorbable pacing wires. We manufactured completely resorbable temporary pacing wires using molybdenum as electrical conductor and assessed their function, degradation and biological compatibility. Our study represents an important step in the development of a safer approach to the treatment of rhythm disturbances after cardiac surgery. [Display omitted] [ABSTRACT FROM AUTHOR]

Open in new tab Download slide OBJECTIVES Multi-organ failure is one of the leading causes of mortality after cardiac surgery for infective endocarditis (IE). Although the randomized evidence does not support the use of haemoadsorption during cardiac surgery for IE, observational studies suggest a beneficial effect in selected patient groups. Staphylococcus aureus is the most common pathogen, and its presence is an independent mortality predictor. We aimed to analyse the effect of haemoadsorption in patients with IE caused by S. aureus. METHODS This is a post hoc analysis of the REMOVE trial that randomized 288 patients with IE who underwent cardiac surgery with haemoadsorption using CytoSorb® or control. The primary outcome was ΔSequential Organ Failure Assessment (SOFA), defined as the difference between the mean total postoperative and baseline SOFA score within 24 h of surgery. RESULTS Among the total of 282 patients included in the modified intention-to-treat analysis of the REMOVE trial, 73 (25.9%) had S. aureus IE (38 patients in the haemoadsorption group and 35 patients in the control group). The overall ΔSOFA did not differ between the intervention groups in patients with S. aureus IE (mead difference = −0.4, 95% confidence interval −2.3 to 1.4, P  = 0.66) and neither did 30-day mortality (hazard ratios = 1.32, 95% confidence interval 0.53–3.28, P  = 0.55). No differences were observed with regard to any of the other secondary outcomes. CONCLUSIONS Based on a post hoc analysis from REMOVE trial, the intraoperative use of haemoadsorption in patients with S. aureus IE was not associated with reduction of postoperative organ dysfunction, 30-day mortality or other major clinical end points.

Objective: Patients undergoing heart surgery are at high risk of postoperative fluid accumulation due to long procedures and cardiopulmonary bypass. In the present study, we sought to investigate the prevalence of postoperative fluid accumulation and its relation to adverse events in patients undergoing cardiac surgery. Methods: CAREBANK is prospective, single-center cohort study focusing on the adverse events after cardiac surgery. The study population was divided into 2 groups based on 5% postoperative weight gain. All the in-hospital adverse events are registered on the database. The end points of the present study were length of hospital stay, length of intensive care unit stay, occurrence of new-onset atrial fibrillation after hospital major bleeding episodes major cardiac events, cerebrovascular events, and death. Three-month and 1-year follow-up data also include all major adverse events. Results: Altogether 1001 adult cardiac surgery patients were enrolled. The most frequent operations were coronary artery bypass grafting (56.3%). Five hundred fifty-four out of 939 (59.0%) patients had ≥5% weight gain during index hospitalization. Patients with a weight gain ≥5% were more likely to be women, have lower body mass index, had heart failure, and more often had preoperative atrial fibrillation. In-hospital period fluid accumulation was associated with reoperation due bleeding and longer total hospital stay. At 3 months' follow-up, weight gain 5% or more was associated with increased occurrence of new-onset atrial fibrillation, this was not reflected in the occurrence of strokes, transient ischemic attacks, or myocardial infarctions. Conclusions: Postoperative fluid excess is associated with adverse outcomes in cardiac surgery. Women, low-weight patients, and patients with cardiac failure or atrial fibrillation are prone to perioperative fluid accumulation.

Introduction: The objectives of this study were to assess the role of neuromarkers like glial fibrillary acidic protein (GFAP), brain-derived neurotrophic factor (BDNF), protein S100 (pS100), and neuron-specific enolase (NSE) as diagnostic markers of acute brain injury and also as prognostic markers for short-term neurodevelopmental impairment. Methods: Pediatric patients with congenital heart defects (CHDs) undergoing elective cardiac surgery were included. Neurodevelopmental functioning was assessed preoperatively and 4–6 months postoperatively using the Denver Developmental Screening Test II. Blood samples were collected preoperatively and postoperatively. During surgery, regional cerebral tissue oxygen saturation was monitored using near-infrared spectroscopy (NIRS). Results: Forty-two patients were enrolled and dichotomized into cyanotic and non-cyanotic groups based on peripheric oxygen saturation. Nineteen patients (65.5%) had abnormal developmental scores in the non-cyanotic group and eleven (84.6%) in the cyanotic group. A good diagnostic model was observed between NIRS values and GFAP in the cyanotic CHD group (AUC = 0.7). A good predicting model was observed with GFAP and developmental scores in the cyanotic CHD group (AUC = 0.667). A correlation was found between NSE and developmental quotient scores (r = 0.09, p = 0.046). Conclusions: From all four neuromarkers studied, only GFAP was demonstrated to be a good diagnostic and prognostic factor in cyanotic CHD patients. NSE had only prognostic value.

Introduction. Coronavirus disease (COVID-19)-associated pneumonia was a dangerous disease at the beginning of 2021. However, there are almost no records of early infectious endocarditis of prosthetic heart valve in the presence of such a disease. We present an interesting clinical case of successful treatment of complicated pathology. The COVID-19 outbreak involved unique clinical complications that were superimposed on the progressive heart failure due to prosthetic mitral valve dysfunction (its detachment) which did not allow time for active antiinflammatory therapy. Urgent replacement of the prosthesis made it possible to eliminate the infection and paved the way for successful long-term antibacterial, antifungal and antiviral therapy. The aim. To determine the features of management of patients with complex clinical pathology: prosthetic valve endocarditis associated with COVID-19 and severe lung inflammation in the early postoperative period. Case report. This work presents rare clinical case. A 46-year old male patient underwent successful surgery (mitral valve replacement with posterior leaflet preservation and left atrium resection) at the Department of Surgical Treatment of Acquired Heart Diseases of the National Amosov Institute of Cardiovascular Surgery and was discharged in satisfactory condition. One month later, he was hospitalized again and diagnosed with an early infectious endocarditis of prosthetic mitral valve and bilateral polysegmental COVID-19-associated pneumonia. After a week of medicinal preparation (antibacterial therapy), the patient underwent repeat mitral valve replacement in the presence of progressive heart insufficiency due to increasing paravalvular insufficiency. Postoperative period elapsed without significant complications. The patient was discharged in satisfactory condition on day 15 after surgery and primary rehabilitation. Conclusion. Having a specific etiology, pneumonia significantly damaged mitral prosthesis structures by increasing paravalvular insufficiency. Consequently, the patient underwent life-saving repeat mitral valve replacement in the presence of COVID-19-associated pneumonia and under massive antibacterial treatment which continued for 60 days after the patient’s discharge. An important element of successful treatment of COVID-19-associated pneumonia is the selection of adequate antibacterial, antifungal and antiviral drugs.

Background Infective endocarditis represents a life‐threatening disease with high mortality rates. A fraction of patients receives exclusively conservative antibiotic treatment due to their comorbidities and high operative risk, despite fulfilling criteria for surgical therapy. The aim of the present study is to compare outcomes in patients with infective endocarditis and indication for surgical therapy in those who underwent or did not undergo valve surgery. Methods and Results Three databases were systematically assessed. A pooled analysis of Kaplan–Meier–derived reconstructed time‐to‐event data from studies with longer follow‐up comparing conservative and surgical treatment was performed. A landmark analysis to further elucidate the effect of surgical intervention on mortality was carried out. Four studies with 3003 patients and median follow‐up time of 7.6 months were included. Overall, patients with an indication for surgery who were surgically treated had a significantly lower risk of mortality compared with patients who received conservative treatment (hazard ratio [HR], 0.27 [95% CI, 0.24–0.31], P

Background Scarce data are available comparing infective endocarditis (IE) following surgical aortic valve replacement (SAVR) and transcatheter aortic valve replacement (TAVR). This study aimed to compare the clinical presentation, microbiological profile, management, and outcomes of IE after SAVR versus TAVR. Methods Data were collected from the "Infectious Endocarditis after TAVR International" (enrollment from 2005 to 2020) and the "International Collaboration on Endocarditis" (enrollment from 2000 to 2012) registries. Only patients with an IE affecting the aortic valve prosthesis were included. A 1:1 paired matching approach was used to compare patients with TAVR and SAVR. Results A total of 1688 patients were included. Of them, 602 (35.7%) had a surgical bioprosthesis (SB), 666 (39.5%) a mechanical prosthesis, 70 (4.2%) a homograft, and 350 (20.7%) a transcatheter heart valve. In the SAVR versus TAVR matched population, the rate of new moderate or severe aortic regurgitation was higher in the SB group (43.4% vs 13.5%; P <.001), and fewer vegetations were diagnosed in the SB group (62.5% vs 82%; P <.001). Patients with an SB had a higher rate of perivalvular extension (47.9% vs 27%; P <.001) and Staphylococcus aureus was less common in this group (13.4% vs 22%; P =.033). Despite a higher rate of surgery in patients with SB (44.4% vs 27.3%; P <.001), 1-year mortality was similar (SB: 46.5%; TAVR: 44.8%; log-rank P =.697). Conclusions Clinical presentation, type of causative microorganism, and treatment differed between patients with an IE located on SB compared with TAVR. Despite these differences, both groups exhibited high and similar mortality at 1-year follow-up. [ABSTRACT FROM AUTHOR]

Background: Patients with coronary artery heart disease frequently suffer concomitant carotid vascular disease and are at high perioperative risk for neurological adverse events. Several concepts regarding the timing and modality of carotid revascularization are controversially discussed in patients with heart disease. Current guidelines recommendations on myocardial revascularization recommend a concomitant carotid endarterectomy (CEA) in patients with a history of stroke/transient ischemic attack (TIA) or 50–99% grade of the carotid stenosis. Our study aimed to analyze early outcome parameters of patients undergoing coronary artery bypass grafting (CABG), but also including concomitant heart valve surgery and simultaneous CEA. Methods: This study retrospectively analyzed a cohort of 111 patients from our institutional database undergoing heart surgery with CABG or heart-valve surgery between 2010 and 2020 with concomitant carotid surgery due to significant carotid stenosis. Results: Patients undergoing heart and simultaneous carotid surgery were 77 ± 8.0 years of age with a body mass index of 28 ± 1.7 kg/m2 and a mean EuroSCORE II of 6.5 ± 2.3. Most patients (61%) had a smoking history and arterial hypertension (97%). The preoperative mean grade of internal carotid stenosis was 87 ± 4.2%, 13% of patients suffered from internal carotid artery stenosis on both sites. In total, 4.5% of patients had previously undergone internal carotid artery intervention before and 6.3% had a history of stroke with a persistent neurologic disorder in 1.8%, 8.9% of cases had prior TIA. Thirty-day all-cause mortality was 6.3% and postoperative neurologic events occurred with 7.2% TIA and 4.5% of disabling stroke. Conclusion: Within the reported patient population of coronary artery heart disease and significant internal carotid stenosis, a one-time approach with CABG or heart-valve surgery and CEA is safe and feasible as justified by clinical and neurological postoperative outcomes.

Objective: Disturbance in gas exchange leads to increased ventilation needs, time to stay in the ICU and death. Arterial‑alveoli oxygen gradient (A‑a) has been studied in adults but has not been considered in children under one year of age who have congenital heart disease and had undergone heart surgery. We decided to examine (A‑a) in these patients. Materials and Methods: This study is a retrospective study. Patients were divided into two groups based on mortality. Arterial blood gas information was extracted the post‑anesthesia, post‑bypass, and 4 hours to 16 hours after surgery. The values (A‑a) were calculated using a standard formula. Data were analyzed by SPSS software. P < 0.05 was considered statistically significant. Results: 14 boys and 9 girls were examined. Among these patients, four girls and three boys died. Arterial‑alveolar oxygen gradient changes are similar in the living and the dead (P = 0.508). The mean arterial‑alveolar oxygen gradients did not show a significant difference between the alive persons and the dead (P = 0.337). Arterial‑alveolar oxygen gradient changes during the time, and this change was statistically significant (P = 0.000). Arterial‑alveolar oxygen gradient in cardiac surgery in children under one year of age declines up to 16 hours after surgery. The duration of hospitalization (P = 0.290 (or intubation in the ICU (P = 0.792) does not affect the alveolar‑arterial oxygen gradient. Conclusion: Arterial‑alveolar changes in oxygen in heart surgery in children under one year of age were significant during the time and generally decreased 16 hours after the surgery. There was no statistically significant relationship between the length of hospital stay or intubation in the ICU with the arterial alveolar oxygen gradient. [ABSTRACT FROM AUTHOR]

BACKGROUND: The activation of the patient from the day after an acquired mitral valve (MV) defect with standard cardiorehabilitation surgery and further physical training at an early uncomplicated inpatient stage of the postoperative period appears promising to improve not only the functional status but also the quality of life (QL). AIM: Our aim was to examine the effect of early physical rehabilitation on the dynamics of anxiety, depression, and QL in patients after surgical correction of the MV defect. MATERIALS AND METHODS: The study included 80 patients (median age 60.8 [47.5; 69.0] years) who underwent surgical correction of an acquired MV defect. Starting from the 7th day after the surgery, patients were assessed for functional status, and the intensity of the training load was selected, and this was done again on the 24th day after the surgery. Moreover, the QL parameters on the SF-36 scale and levels of anxiety and depression on the Hospital Anxiety and Depression Scale (HADS) were evaluated. The control group (n=47) underwent a standard cardiac rehabilitation program from 1st day after surgery. In the main group (n=33), based on the results of the cardiopulmonary exercise testing, physical training on a treadmill was initiated for 14 days, from the 8th day after the surgery, in addition to a personalized training program. RESULTS: In addition to improving the functional state, early physical training improved the dynamics of QL indicators in the main group. After 14 days of treadmill training, the physical health component increased from a median of 35.1 to 64.4 (p=0.03), and the mental health component from a median of 49.1 to 82.1 (p=0.03). In addition, after the early physical rehabilitation program in the main group, the number of people without anxiety and depression, according to the HADS scale, significantly increased from 9% to 27.3% (p=0.04), whereas the dynamics of the QL, anxiety, and depression levels in the control group were not significant. CONCLUSION: Early physical rehabilitation, including moderate-intensity workouts with an individual calculation of the speed / angle of the treadmill, starting from 8 days after surgical correction of the acquired MV defect demonstrated efficacy in improving the QL and reducing anxiety and depression levels 24 days after surgery.

BackgroundRedo sternotomy aortic root surgery is technically demanding, and the evidence on outcomes is mostly from retrospective, small sample, single-centre studies. We report the trend, early clinical results and outcome predictors of redo aortic root replacement over 20 years in the United Kingdom.MethodsWe retrospectively analysed collected data from the UK National Adult Cardiac Surgery Audit (NACSA) on all redo sternotomy aortic root replacements performed between 30th January 1998 and 19th March 2019. We analysed trends in the volume of operations, characteristics of hospital survivors vs. non-survivors, and predictors of in-hospital outcomes.ResultsDuring the study period, 1,107 redo sternotomy aortic root replacements were performed (median age 59, 26% of patients were females). Eighty-four per cent of cases (N = 931) underwent a composite root replacement, 11% (N = 119) had homograft root replacement and valve-sparing root replacement was performed in 5.1% (N = 57) of cases. There was a steady increase in the volume of redo sternotomy root replacements beyond 2006, from an annual volume of 22 procedures in 2006 to 106 procedures in 2017. Hospital mortality was 17% (n = 192), postoperative stroke or TIA occurred in 5.2% (n = 58), and postoperative dialysis was required in 11% (n = 109) of patients. Return to the theatre for bleeding/tamponade was required in 9% (n = 102) and median in-hospital stay was 9 days. Age >59 (OR: 2.99, CI: 1.92–4.65, P 0.05).ConclusionsRedo sternotomy aortic root replacement still carries significant morbidity and mortality and is sporadically performed across surgeons and centres in the UK.

BackgroundThe suggested threshold level of cardiac troponin T elevation after cardiac surgery is not very clear, and the values recommended by various guidelines and literature reports are quite different.MethodsIn this retrospective cohort study, we collected clinical data of patients who underwent heart surgery at Tsinghua University First Hospital between January 2015 and December 2022. Using the high-sensitivity cardiac troponin T levels (reference upper limit: 14 ng/L) measured at 1–3 days postoperation, the relationship between the cardiac troponin T level and the 30-day mortality risk was evaluated using Cox regression analysis.ResultsAmong the 3,128 patients included in this study, the types of operations mainly consisted of coronary artery bypass graft (CABG, 1,164, 37.2%), aortic valve replacement (AVR, 735, 23.5%), and other cardiac operations (1,229, 39.3%). Within 30 days postoperation, 57 patients (1.8%) died and 72 patients (2.3%) developed major vascular complications. In patients undergoing CABG or AVR, the cardiac troponin T threshold level measured within one day postoperation related to an increased 30-day mortality was determined to be 3,012 ng/L (95% CI: 1,435–3,578 ng/L), which is 218 times higher than the reference upper limit. In patients undergoing other cardiac operations, this threshold was 5,876 ng/L (95% CI: 2,458–8,119 ng/L), which is 420 times higher than the reference upper limit.ConclusionThe high-sensitivity cardiac troponin T level associated with an increased 30-day mortality risk after cardiac surgery is significantly higher than the current recommendations for defining clinically important perioperative myocardial injury.

Following surgery, over 50% of cardiac surgery patients report anxiety, stress and/or depression, with at least 10% meeting clinical diagnoses, which can persist for more than a year. Psychological distress predicts post-surgery health outcomes for cardiac patients. Therefore, post-operative distress represents a critical recovery challenge affecting both physical and psychological health. Despite some research identifying key personal, social, and health service correlates of patient distress, a review or synthesis of this evidence remains unavailable. Understanding these factors can facilitate the identification of high-risk patients, develop tailored support resources and interventions to support optimum recovery. This narrative review synthesises evidence from 39 studies that investigate personal, social, and health service predictors of post-surgery psychological distress among cardiac patients. The following factors predicted lower post-operative distress: participation in pre-operative education, cardiac rehabilitation, having a partner, happier marriages, increased physical activity, and greater social interaction. Conversely, increased pain and functional impairment predicted greater distress. The role of age, and sex in predicting distress is inconclusive. Understanding several factors is limited by the inability to carry out experimental manipulations for ethical reasons (e.g., pain). Future research would profit from addressing key methodological limitations and exploring the role of self-efficacy, pre-operative distress, and pre-operative physical activity. It is recommended that cardiac patients be educated pre-surgery and attend cardiac rehabilitation to decrease distress. [ABSTRACT FROM AUTHOR]

A good predicting model was observed with GFAP and developmental scores in the cyanotic CHD group (AUC = 0.667). A correlation was found between NSE and developmental quotient scores (r = 0.09, p = 0.046). Conclusions: From all four neuromarkers studied, only GFAP was demonstrated to be a good diagnostic and prognostic factor in cyanotic CHD patients. NSE had only prognostic value.

Our aim was to evaluate the total burden of reoperations after previous repair for atrioventricular septal defects, including long-term survival and identify risk factors for reoperation. All patients with surgical correction for atrioventricular septal defect (AVSD) 1993- 2020 underwent a follow-up in October 2020. Clinical data were obtained by retrospective review and evaluated with Kaplan-Meier and competing risk analysis. Of 477 patients who underwent initial repair, 53 patients (11.1%) underwent a total of 82 reoperations. The perioperative mortality at reoperation was 3.8% (2/53). There were no late deaths (0/51) during follow-up. In patients requiring reoperation for left atrioventricular valve regurgitation, a re-repair was performed in 90% (26/29) at first attempt. Estimated overall survival was 96.2 ± 2.6% (95% CI 91.2-100) in the Any reoperation group and 96.7 ± 0.9% (95% CI 94.9-98.5) in the No reoperation group at 20 years (P = 0.80). The cumulative incidence function of Any reoperation (with death as competing risk) was 13.0% (95% CI 9.4-16.5) at 20 years. Independent risk factors for Any reoperation included severe mitral regurgitation after primary repair (HR 40.7; 95% CI 14.9-111; P < 0.001). The risk of perioperative mortality in AVSD patients undergoing reoperation was low in the present study. Long-term survival was very good and not significantly different when compared to patients who did not need reoperation. Re-repair for left atrioventricular valve regurgitation was possible in most cases and showed long-term durability. Our data suggest that reoperations after primary repair of AVSD have very good long-term outcomes when performed at a high-volume pediatric cardiac surgery center.

Background and Aim: Most of the complications after heart surgery are related to immobility. Early mobilization helps prevent these problems from occurring. Despite the awareness of the importance of early mobilization, its implementation rate is still low due to the presence of many obstacles. Appreciative inquiry has been introduced as a key strategy for creating change. This study aimed to investigate the effect of the implementation of an appreciative inquiry strategy on the quality of early mobilization. Methods: This clinical trial research was conducted in Tehran Jamaran Hospital on 98 patients undergoing open heart surgery in 1401. The sampling method was purpose-based based on the inclusion criteria. The quality of early mobilization of the patients was evaluated using a researcher-made checklist, which was validated. The intervention in the test group was carried out in the form of focused group discussions of four people regarding the strategy of appreciative inquiry for the implementation of Early mobilization of patients. The leaders of the open-heart intensive care unit, including the head of the department, his deputy, and the heads of the shifts participated in the discussions. The results were analyzed by statistical software SPSS version 22 using independent t, Mann-Whitney, and chi-square tests and analysis of variance. Results: The findings showed that the patients of the two test and control groups had no significant differences in terms of demographic characteristics, surgery characteristics, history of smoking and drug use, and underlying diseases. The results of checking the checklist scores using chi-square test showed that with the implementation of the Appreciative inquiry strategy among department leaders, the average score of the checklist for the quality of the implementation of the Early mobilization process went from 8/4 (±1/4) in the control group to 11/6 (±1/4) in the test group (P<0.001). Conclusion: This study showed that the implementation of the appreciative inquiry strategy is effective in changing the approach of nurses regarding early mobilization and consequently creating a positive change for the implementation of this process. Considering the need to change the approach in different areas of nursing, including early mobilization, it is recommended This strategy can be used in nursing with the aim of creating positive changes.

Right ventricular (RV) dysfunction early after tetralogy of Fallot (TOF) increases post-operative morbidity. We investigated associations of circulating biomarkers and socioeconomic factors with early post-operative RV systolic function. Single-center prospective cohort study of infants undergoing TOF repair. Six serologic biomarkers of myocardial fibrosis and wall stress collected at the time of surgery were measured with immunoassay. Geocoding was performed for socioeconomic factors. Multivariate adaptive regression splines (MARS) models identified factors associated with RV function parameters: fractional area change (FAC), global longitudinal strain and strain rate, and free wall strain and strain rate. Seventy-one patients aged 3.5 months (IQR 2.4, 5.2) were included. Galectin-3 was the highest ranked predictor for FAC, global longitudinal strain, and free wall strain, and procollagen type-I carboxy-terminal propeptide (PICP) was the highest ranked predictor for global longitudinal strain rate and free wall strain rate. Several neighborhood characteristics were also highly ranked. Models adjusted R2 ranged from 0.71 to 0.85 (FAC, global longitudinal strain/strain rate), and 0.55–0.57 (RV free wall strain/strain rate). A combination of serologic biomarkers, socioeconomic, and clinical variables explain a significant proportion of the variability in RV function after TOF repair. These factors may inform pre-operative risk-stratification for these patients. [ABSTRACT FROM AUTHOR]

ABSTRACT Background: Bibliometric studies can direct academics. There have been many specialties and subspecialties where bibliometric analyses have been published, but our literature search yielded no bibliometric analysis of the frozen elephant trunk (FET) procedure. The primary objective of this study was to identify the most frequently referenced papers on FET procedure research and investigate the research trends. Methods: A dataset of all scientific journals published in the English language was created using the Web of Science (WOS) database. This search was then cross-referenced with a comparable search phrase query of the Scopus Library database in order to locate any publications that could have been overlooked during the first search. Citation counts were used to rank the articles. Also knowledge maps were created using VOSviewer software, and articles and reviews pertaining to the FET procedure in CVDs were taken from the WOS Core Collection. Results: A total of 484 documents on Scopus and 494 documents on WOSpertaining to the FET procedure were included in this study. The leading countries that published most of the research were Germany, Japan, and Italy in both databases. The largest subset of the FET procedure articles was published since 2012. The most cited authors were Karck, Shrestha, and Uchida. The mean Hirsch index of the articles was 40 and 10.47 per article. Conclusion:This study offers information on the traits and standards of the FET procedure literature that has received the most citations, as well as a ranking of the most important sources for this procedure. This work provides as a guide to what constitutes a citeable FET procedure publication by offering the most important references and mostly publishing journals.
