Extracorporeal membrane oxygenation (ECMO) plays a crucial role in managing heart and respiratory failure. However, it is associated with complications such as bleeding, acute renal failure, neurological issues, and thrombosis. Cerebral venous sinuses thrombosis (CVST) is a rare condition that primarily affects young females, especially those of childbearing age. CVST can result from multiple factors, both congenital and acquired, such as pregnancy, dehydration, oral contraceptives, and the postpartum period. The most common and nonspecific symptom is headache. Notably, the occurrence of CVST during ECMO has not been documented in adult patients. In this case report, we present the case of a 29-year-old lactating mother who was admitted to our hospital with complaints and clinical features indicative of community-acquired pneumonia. Despite conventional treatment, her oxygen requirement increased; therefore, she was placed on veno-venous ECMO (VV ECMO). Her condition gradually improved, and she was extubated while still on ECMO support (Awake ECMO). However, a day later of successful weaning from ECMO, she reported blurred vision and proptosis. Magnetic resonance imaging (MRI) and MR venography (MRV) of the brain showed features suggestive of CVST. She was promptly treated with anticoagulation and later discharged with minimal residual complications. This paper emphasizes the importance of early clinical recognition and treatment with anticoagulants in cases of CVST during ECMO for improved outcomes. [ABSTRACT FROM AUTHOR]

Cardiac masses are relatively rare, with a right atrial mass being even more rare. Right atrial masses pose a diagnostic dilemma owing to the diverse range of potential diagnoses, even when the clinical context and initial imaging modalities are thoroughly evaluated. A right atrial mass can have a varied etiology as it can be a physiological variant, or a neoplastic or a non-neoplastic mass with each having a separate line of management. This paper aims to highlight the etiology and the surgical outcomes of patients having a right atrial mass. [ABSTRACT FROM AUTHOR]

Biventricular assist devices (BiVADs) using the CentriMag™ system are being used increasingly as a form of short-term mechanical circulatory support for the treatment of acute cardiogenic shock from any aetiology. They can be used as a bridge to decision, recovery or transplantation. BiVADs are associated with better clinical outcomes when compared to veno-arterial (VA) extracorporeal membrane oxygenator (ECMO) systems. In this paper, we describe a safe and reproducible method of BiVAD implantation using the CentriMag™ system at our institution. [ABSTRACT FROM AUTHOR]

Purpose: Recently, the use of rapid deployment (RD) aortic valve prostheses has been introduced for the treatment of aortic valve replacement (AVR), showing excellent hemodynamic performances. According to these data, some groups have proposed new RD valves as an alternative solution in the case of infective aortic endocarditis (IAE) to reduce the use of foreign materials, and the manipulation of the annulus. The aim of this review is to report the results of early clinical experiences with the use of RD bioprostheses in the case of IAE, in order to discuss technical and clinical aspects of this emerging strategy to better elucidate its advantages and limitations as a potential therapeutic solution. Methods: An in-depth search of PubMed from January to March 2023 was performed. English-language articles were selected independently by authors following the criteria in order to consider all available experiences (full papers, case reports, and case series) that have investigated the use of RD in case of IAE. Results: The use of rapid deployment bioprosthesis represents a bailout strategy in case of severe aortic valve endocarditis and should be evaluated with caution in selected cases. This review collects the first, initial, and pioneering experiences of the use of the RD prosthesis in case of infective endocarditis, particularly when the fragility of the annular tissues precludes a secure anchoring of sutured prostheses. The reduced use of foreign materials by minimizing the number of stitches, the reduced cardiopulmonary bypass (CPB) and aortic cross-clamp times, and the excellent hemodynamic performances associated with the use of RD bioprosthesis represent the most important advantages that could justify their use in the setting of aortic valve endocarditis. Conclusion: Although there are few anecdotal experiences, surgical aortic valve replacement with the use of RD represents an emerging strategy in case of aortic valve endocarditis. Its advantages, pros, and cons are under debate, and robust clinical trials are needed to demonstrate its safety and efficacy. [ABSTRACT FROM AUTHOR]

Introduction: To date, no systematic review or meta-analysis study has been conducted regarding the use of video-assisted thoracoscopic surgery (VATS) in the removal of intrathoracic foreign bodies (FB). This systematic review aims to evaluate the feasibility of VATS in the removal of intrathoracic FBs. Methods: PubMed/MEDLINE, CINAHL, Web of Science, EMBASE, and Cochrane Library databases were systematically searched to identify reports published up to April 1, 2022. Results: The initial systematic search revealed a total of 208 papers, of which only 54 studies reporting 71 cases were included in this systematic review. Among the patients, 46 (64.8%) were male, 22 (31%) were female, and 3 (4.2%) were unknown. The mean age was 34.5 ± 24.3 years (1 day to 98 years). The patients were of 3 etiologic groups: iatrogenic (31, 43.7%), traumatic (28, 39.4%), and accidental (9, 12.7%). Most of the patients were emergency cases (27, 38%). The most frequently used imaging modalities to diagnose these foreign bodies were X-ray (46, 64.8%), followed by computed tomography (44, 62%), and ultrasonography (16, 22.5%). About 43% of all the foreign bodies were therapeutic equipment. The pleural cavity had the highest involvement (36.8%), followed by the lung parenchyma (14.6%) and thoracic cavity (13.2%). Regardless of the number of access ports, all the patients had a good clinical outcome. Conclusion: VATS is a safe and effective method for the removal of intrathoracic FBs from various thoracic sites that are associated with a good clinical outcome — in both elective and emergency cases.

Left ventricular assist devices (LVADs) improve survival and quality of life for patients with advanced heart failure but are associated with high rates of thromboembolic and hemorrhagic complications. Antithrombotic therapy is required following LVAD implantation, though practices vary. Identifying a therapeutic strategy that minimizes the risks of thromboembolic and hemorrhagic complications is critical to optimizing patient outcomes and is an area of active investigation. This paper reviews strategies for initiating and maintaining antithrombotic therapy in durable LVAD recipients, focusing on those with centrifugal-flow devices. [ABSTRACT FROM AUTHOR]

This paper reviews the current understanding of the inherited, genetic nature of thoracic aortic aneurysm and dissection (TAAD), as well as the practice of genetic testing for thoracic aortic disease at the Aortic Institute at Yale-New Haven Hospital. [ABSTRACT FROM AUTHOR]

Aortic diseases located in the ascending aorta, aortic arch or proximal descending aorta often require more than one surgical intervention depending on the type of pathology and its extent as well as future anticipated aortic problems. These obstacles were tackled in 1983 by Hans Borst with the introduction of the classic elephant trunk (cET). This was an outstanding and straightforward procedure. Since then, the cET was very often the first surgical approach for patients with extensive aortic pathology of the ascending aorta and arch extending into the downstream aorta. Thirteen years later, Suto and Kato introduced the frozen elephant trunk (fET) which was later on perfectionized by industry and applied in various ways by many surgical groups worldwide. Comparing the cET with the fET raises a lot of difficulties. The lack of randomization and the presence of procedural and complication-related limitations for each technique do not allow for definitive conclusions about the ideal procedure to treat complex aortic pathology. It would be very short-sighted to close all future discussions about the subject with this statement of the Hannover group made in 2011. Since both techniques and its results cannot be compared statistically due to the heterogeneity of patient groups, the lack of randomization, the difference in type and extent of pathology, the differences in surgical techniques, the learning curve in gaining experience in both techniques, and the lack of reporting standards, no scientific conclusion can be drawn as to which technique is most successful. Comparisons may even be considered futile. It is the purpose of this paper merely to make a descriptive observation of both techniques, to discuss some important elements of interest and to give some constructive and useful criticism.

Clear cell sarcoma of the kidney is a rare variety of renal tumor accounting for less than 5% of all pediatric renal tumors. Cardiopulmonary bypass along with hypothermic circulatory arrest is frequently used for management of tumor thrombus extending into supra-hepatic inferior vena cava and right atrium. In this paper, we present a strategy of avoiding circulatory arrest and hypothermia and thereby fast-tracking the recovery in managing a case of clear cell sarcoma of the kidney in a 3.5-year-old child with tumor thrombus extending into the right atrium.

Purpose: Cardiac surgeons are increasingly faced with a more complex patient who has developed a pattern of diffuse coronary artery disease (CAD), which is refractory to medical, percutaneous, and surgical interventions. This paper will review the clinical science surrounding transmyocardial revascularization (TMR) with an emphasis on the results from randomized controlled trials.Methods: Randomized controlled trials which evaluated TMR used as sole therapy and when combined with coronary artery bypass grafting were reviewed. Pertinent basic science papers exploring TMR's possible mechanism of action along with future directions, including the synergism between TMR and cell-based therapies were reviewed.Results: Two laser-based systems have been approved by the United States Food and Drug Administration (FDA) to deliver laser therapy to targeted areas of the left ventricle (LV) that cannot be revascularized using conventional methods: the holmium:yttrium-aluminum-garnet (Ho:YAG) laser system (CryoLife, Inc., Kennesaw, GA) and the carbon dioxide (CO2) Heart Laser System (Novadaq Technologies Inc., (Mississauga, Canada). TMR can be performed either as a stand-alone procedure (sole therapy) or in conjunction with coronary artery bypass graft (CABG) surgery in patients who would be incompletely revascularized by CABG alone. Societal practice guidelines have been established and are supportive of using TMR in the difficult population of patients with diffuse CAD.Conclusions: Patients with diffuse CAD have increased operative and long-term cardiac risks predicted by incomplete revascularization. The documented operative and long-term benefits associated with sole therapy and adjunctive TMR in randomized trials supports TMR's increased use in this difficult patient population.

Berry syndrome is a rare congenital cardiac anomaly, characterized by distal aortopulmonary window, hypoplasia or interruption of the aortic arch, intact ventricular septum, and aortic origin of the right pulmonary artery and patent ductus arteriosus. Anatomic depiction of each component is important for the diagnosis. Single-stage surgical repair is challenging but feasible with good survival outcomes. The available literature on this anomaly is limited. Hence, this paper aims at reviewing the literature on Berry syndrome. [ABSTRACT FROM AUTHOR]

Hydatid disease is a parasitic infection caused by the tapeworm Echinococcus. It has a worldwide distribution, but it is endemic in certain geographic locations. Hydatid disease can involve any body organ. Cardiac echinococcosis is a rare but potentially very serious complication of hydatid disease. This paper presents a case report of a myocardial hydatid cyst, which was totally excised without the aid of cardiopulmonary bypass. The patient was admitted to the hospital with non-specific symptoms and complaint of atypical chest pain together with palpitations. Transthoracic echocardiography with color Doppler imaging and computerized tomography with contrast were done for diagnosis and for deciding the strategy of operation. With the aid of intraoperative transesophageal echocardiography and controlled fluid evacuation, curative excision was performed after confirming that there is no communication with the cardiac chambers. The patient recovered well and postoperative anti-helminthic therapy was instituted. The patient continues to do well after 4 years of follow-up. [ABSTRACT FROM AUTHOR]

Introduction: In this paper, we describe our experience and early outcomes with critically unwell severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) patients who required extracorporeal membrane oxygenation (ECMO). We present our standard practices around ECMO decision-making, retrieval, cannulation, ventilation, anticoagulation, tracheostomy, imaging and steroids. Methods: A retrospective cohort study using data from the hospital notes on all SARS-CoV-2 patients who required extracorporeal support at St Bartholomew's Hospital between 1 March 2020 and 31 July 2020. In total, this included 18 patients over this time period. Results: In total, 18 patients were managed with extracorporeal support and of these 14 survived (78%) with 4 deaths (22%). The mean duration from hospital admission to intubation was 4.1 ± 3.4 days, mean time from intubation to ECMO 2.3 ± 2 days and mean run on ECMO 17.7 ± 9.4 days. Survivor mean days from intubation to extubation was 20.6 ± 9.9 days and survivor mean days from intubation to tracheostomy decannulation 46.6 ± 15.3 days. Time from hospital admission to discharge in survivors was a mean of 57.2 ± 25.8 days. Of the patients requiring extracorporeal support, the initial mode was veno-venous (VV) in 15 (83%), veno-arterial (VA) in 2 (11%) and veno-venous-arterial (VVA) in 1 (6%). On VV extracorporeal support, 2 (11%) required additional VVA. Renal replacement therapy was required in 10 (56%) of the patients. Anticoagulation target anti-Xa of 0.2–0.4 was set, with 10 (56%) patients having a deep vein thrombosis or pulmonary embolism detected and 2 (11%) patients suffering an intracranial haemorrhage. Tracheostomy was performed in 9 (50%) of the patients and high-dose methylprednisolone was given to 7 (39%) of the patients. Conclusion: In our cohort of patients with severe SARS-CoV-2 respiratory failure, a long period of invasive ventilation and extracorporeal support was required but achieving good outcomes despite this. There was a significant burden of thromboembolic disease and renal injury. A significant proportion of patients required tracheostomy and steroids to facilitate weaning. [ABSTRACT FROM AUTHOR]

Chylothorax is the accumulation of chyle in the pleural cavity that typically contains a high concentration of triglycerides. Blunt chest trauma is a rare cause. The aim of this study is to review all of the reported cases of chylothorax caused by blunt chest trauma. Available databases were explored systematically for the condition and the eligible papers were included. The literature search revealed 30 studies with 39 cases, 72.3% of the cases were male, and 21.7% of the patients were female. The age range varied between 4 and 75 years with a mean age of 35.8 years. All of the patients were diagnosed after fluid sampling from the pleural fluid by thoracentesis and/or chest tube insertion. About 71.4% of the patients were treated successfully by conservative management: others (28.6%) were managed surgically. Although it is a rare condition, persistent milky drainage after blunt chest trauma should raise the suspicion of chylothorax. Pleural fluid sampling is the cornerstone of the diagnosis. In the majority of the cases, conservative treatment is quite enough. Surgery is indicated whenever non-operative measures failed. [ABSTRACT FROM AUTHOR]

Despite the introduction of mechanical circulatory assist systems in India two decades ago, there has not been their wide usage due to two main reasons: (1) economic-financial unaffordability and (2) lack of social support. There have been a number of significant steps taken by the government and by the media for augmenting awareness for organ donation. A sizeable donor pool in India falls into the category of marginal donors, due to a variety of reasons like geographical distances, lack of rapid transport, suboptimal donor management due to the lack of resources, and trained manpower in hospitals where donor harvest is done. Consequently, the usage of the heart as a donor organ is less than 20% in India. There is a lack of statistical data regarding the usage of heterotopic heart transplants, due to the absence of a registry, since the procedure is rarely performed, and comparative results are difficult to obtain due to different subsets of both donors and the recipients. The original papers by Barnard and Cooper cannot be extrapolated in the modern context, as these publications were in the pre-cyclosporin era. Orthotopic heart transplantation (OHT) is a well-established and commonly utilized procedure for patients with end-stage heart failure. Heterotopic heart transplantation (HHT) is a surgical procedure that allows the graft to be connected to the native heart in a parallel fashion to provide a kind of biological biventricular or univentricular (left ventricular support). It was performed first in human beings by Barnard in 1974 [S, J., 49:, Afr, Med, 1975, 303–12]. [ABSTRACT FROM AUTHOR]

Purpose: The aim of this paper is to review the literature on recurrent pectus excavatum (PE) and present our surgical approach to a complex case of recurrent PE in an adult patient at a Mexican Hospital. Methods: We present the case of an adult patient with severe and symptomatic PE, with history of a failed Nuss procedure 1 year previous our intervention, which consisted of a combination of both classic techniques, by performing an osteochondrectomy of affected cartilages and placing a titanium bar substernal and stabilizing coastal arches with secondary osteosynthesis system (Stratos ™ system, medXpert, Germany). Results: Adequate correction of thoracic silhouette and both cardiac and respiratory disorders in the 1-year follow-up was achieved as indicated by the improvement of the patient's Haller index. Conclusion: Successful surgical correction of pectus excavatum is achieved when the thoracic silhouette is restored, thus improving cardiopulmonary symptoms. As there are many different techniques available, the more minimally invasive ones are reserved for mild cases, but the treatment of complex cases as in our patient requires a combination of multiple techniques and reconstruction materials in order to achieve adequate correction of the thoracic deformity and reduce recurrence rate.

Objective: Since the intra-extracardiac Fontan (IECF) was popularized by Jonas in 2008, its claimed advantages over the traditional extracardiac or lateral tunnel Fontan are simplicity, suitability for nearly all subsets, flow characteristics, low risk of sinus node artery injury, and possibly, a lower incidence of arrhythmias. In this paper, we present our early experience with this modification of the Fontan operation. Methods: Between 2009 and 2018, 10 patients underwent IECF on cardiopulmonary bypass (CPB) and cardioplegic arrest at our institute. Analysis of preoperative, intraoperative, and early follow-up results was performed. A polytetrafluoroethylene (PTFE) graft was sutured proximally to the orifice of the inferior vena cava (IVC) and distally to the ipsilateral bidirectional superior cavopulmonary (BSCP) junction. Results: Nine patients had undergone a previous BSCP connection, and one patient had a primary IECF. Diagnoses were double outlet right ventricle (n = 2), unbalanced atrioventricular septal defect with associated atrioventricular valve regurgitation (n = 3), single ventricle with anomalies of cardiac situs (n = 2), and tricuspid atresia with borderline pulmonary arteries (n = 1) or tricuspid atresia with borderline pulmonary artery pressures (n = 2). Median aortic cross-clamp and CPB times were 42 min and 82 min respectively. There were no early or late deaths. Median intensive care stay was 3 days (1 to 23 days). There were no arrhythmias. Mean duration of pleural effusions was 9.5 (median 5.5) days. There were no arrhythmias at a median follow-up of 5 years (range 1 month to 9.3 years). Conclusion: The IECF is simple, particularly at reoperations, in borderline patients and those needing concomitant intracardiac procedures. Early results are promising. These patients need constant surveillance. [ABSTRACT FROM AUTHOR]

Introduction: The emergence of minimally invasive thoracic surgery has positively impacted postoperative recovery. Robotic-assisted thoracoscopic surgery (RATS) has been shown to have equivalent short- and long-term outcomes as compared with video-assisted thoracoscopic surgery (VATS). The introduction of RATS offers a three-dimensional high-definition image, improved ergonomics, and wristed movement. The purpose of this paper was to define the learning curve of RATS. Methods: This study is a retrospective review of a single surgeon's RATS experience in a community hospital. All patients who underwent RATS between December 2011 and April 2014 were included. The cohort was divided into 2 groups: "early" and "late." These groups were created based on the date before or after February 2013, respectively. Data is presented as means and percentages. Significance was defined as a P value < 0.05. All categorical variables were evaluated with Fisher's exact t test and all continuous variables were compared via a paired t test. Results: Seventy-nine patients were identified with a mean age of 59. There were 39 patients in the early group and 40 in the late. Rates of conversion to open thoracotomy (13% vs 10%, P = 0.74) and operative time (180 vs 204 min, P = 0.34) did not demonstrate any statistical significance between the two cohorts. Postoperative morbidity (21% vs 28%, P = 0.60) and mortality (3% vs 0%, P = 1.00) were equivalent between both groups. There was a higher percentage of lobectomies performed during the late group (38% vs 65%, P = 0.02). Furthermore, these lobectomies were performed at a faster rate in the late group. Conclusion: Based on our experience, the complexity of the operations that can be performed robotically increased with the number of operations performed without an impact on postoperative morbidity and mortality.

Descriptive statistics are essential for summarizing and interpreting clinical data in cardiothoracic surgery. Understanding measures of central tendency and dispersion, such as mean, median, range, variance, and standard deviation, provides insights into patient outcomes and surgical effectiveness. Confidence intervals offer a range for population parameters, enhancing decision-making precision. Data visualization tools like histograms, box plots, and scatter plots illustrate distributions and relationships. Interpreting tables and figures accurately, recognizing biases, and evaluating statistical validity are crucial for applying research findings to clinical practice. These statistical tools ultimately support evidence-based practice and ensure informed decision-making by clinicians. [ABSTRACT FROM AUTHOR]

Objective: The no-touch (NT) technique for saphenous vein graft (SVG) harvesting has been gaining popularity as several trials have shown its superiority in maintaining graft patency. However, this technique's clinical outcome and safety are still disputed and the results vary widely. The aim of this meta-analysis of randomized controlled trials (RCTs) was to assess the effectiveness and safety of this method. Methods: The Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA) guidelines were conducted for this systematic review and meta-analysis. A comprehensive search of the literature was carried out with Embase, Scopus, and PubMed databases. The articles underwent extensive evaluation and analysis. Results: Six RCTs comparing the NT and conventional (CON) techniques were included. Primary outcomes were measured using graft occlusion. Graft failure rates and clinical outcomes including major adverse cardiac and cerebrovascular events (MACCE), all-cause death, myocardial infarction, repeat revascularization, and leg wound complications were evaluated as secondary outcomes. The NT technique significantly decreased graft occlusion (risk ratio (RR) = 0.58; 95% confidence interval (CI) = 0.46 to 0.72; p < 0.001) and failure (RR = 0.65; 95% CI = 0.54 to 0.77; p < 0.001). Safety analysis also showed no significant risk difference for clinical outcomes, and although significantly higher, leg complications in the NT technique are minor and avoidable. Conclusion: The NT technique increases long-term graft patency with no significant risk difference for clinical outcomes compared to the CON technique. However, the leg wound complications are significantly higher in the NT technique compared to the CON technique. [ABSTRACT FROM AUTHOR]

Spinal cord ischemia (SCI) is a major debilitating complication of thoraco-abdominal aortic aneurysm (TAAA) repair, even in experienced centers. Several strategies are employed to reduce the incidence of SCI and the resultant paraplegia, yet the optimum method is unknown. We describe our experience of using the reversed saphenous vein graft (RSVG) as a conduit to reimplant the intercostal arteries (ICAs). We aimed to assess the incidence of SCI when using RSVG in TAAA repair. Eight consecutive patients who underwent elective surgical replacement of the thoraco-abdominal aorta were studied. The mean age of our patients was 48.9 ± 12.1 years with 87.5% being males. A mean of 3.25 ICAs were reimplanted in each patient. No patient developed postoperative SCI or wound complications related to saphenous vein (SV) harvesting. RSVG patency at 3 months was 84.61%. Though the long-term results of this technique are still unknown, this technique is a beneficial and handy alternative without compromising the blood flow to the ICAs. [ABSTRACT FROM AUTHOR]

The surgical management of d-transposition of the great arteries (dTGA), ventricular septal defect (VSD), and left ventricular outflow tract obstruction (LVOTO) poses intricate challenges, demanding tailored surgical interventions. This case report elucidates a patient involving a 9-year-old child with dTGA, VSD, and LVOTO with a dysplastic pulmonary valve with adequate annulus who underwent neo-aortic valve replacement with a mechanical prosthesis, arterial switch, and VSD closure. The recovery of the patient was uneventful and follow-up echocardiogram and clinical evaluation at 18 months have remained satisfactory. We describe the clinical details of this unusual approach for management of dTGA, VSD, and LVOTO. [ABSTRACT FROM AUTHOR]

Coronary stent infection is considered the rarest complication of percutaneous coronary intervention, occurring in less than 0.1% of the cases. In this article, a case of coronary stent infection and acute stent occlusion with surrounding peri-stent coronary abscess has been reported. A 46-year-old male presented to the emergency at our centre on 11/07/2022 with chief complaints of intermittent fever spikes and intermittent chest pain since the past 1 week. He had been diagnosed with acute inferior and posterior wall myocardial infarction on 20/06/2022 and had undergone percutaneous coronary intervention (PCI) with drug eluting stent (DES) implantation to the right coronary artery (RCA) following thrombolysis with tenecteplase at a different center. He was non-diabetic and non-hypertensive and on dual antiplatelet therapy post PCI. On presentation, he was anxious but alert and cooperative. He underwent check coronary angiogram on 30/06/2022 followed by a computerized tomography (CT) coronary angiogram on 12/07/2022. He was finally diagnosed with acute stent occlusion and peri-stent abscess in RCA. Preoperatively, he had raised liver transaminases, mild neutrophilic leukocytosis with normal renal function test values, and a negative blood culture report. He was operated on 14/07/2022. Surgical procedure included infected stent retrieval from RCA and peri-stent abscess drainage. Stent and pus culture sensitivity was negative for causative microorganisms. Post surgery, he had continued fever spikes and antibiotics were escalated. He also developed non-oliguric acute kidney injury (AKI) and pericarditis. He was treated medically for the post-op complications and was discharged on optimal medical management. On follow-up visits, his renal function tests showed improvement and there was no recurrence of fever or chest pain in 1-year follow-up. [ABSTRACT FROM AUTHOR]

Understanding research designs is crucial for cardiothoracic surgeons to enhance their clinical practice and decision-making. This article provides a comprehensive overview of different research study types, including observational and experimental studies, and their relevance to cardiothoracic surgery. Detailed explanations of cohort, case–control, and cross-sectional studies, as well as various types of randomized controlled trials, are presented. Key terms and concepts like bias, validity, and reliability are discussed. Practical case examples from the literature illustrate the application of these research designs, aiding clinicians in selecting the appropriate study design for their research questions.

A 67-year-old male presented to us with symptoms of postprandial abdominal pain for the last 3 months and was not able to take meals for the last month. The computed tomography (CT) angiogram showed complete occlusion in the coeliac artery (CA), superior mesenteric artery (SMA) and inferior mesenteric artery (IMA) with complete occlusion of infrarenal aorta and bilateral iliac arteries. While waiting for elective surgical mesenteric bypass, patient suddenly developed signs of peritonitis for which emergency surgery was done using a Dacron bifurcated graft 12 × 6 mm size. Inflow was taken from the supra coeliac aorta. At 6 months follow-up, the patient was doing well and the CT angiogram showed a patent graft. In our case, the challenge was from where to take inflow, as the patient's aorta was atherosclerotic and infrarenal aorta was completely occluded, and he was also not suitable for endovascular stenting. So, we decided to take inflow from the supra coeliac aorta and a distally mesenteric bypass was done. Although mesenteric ischaemia has very high morbidity and mortality rates, prompt and well-planned mesenteric bypass surgery can save both bowel and patients life as well. [ABSTRACT FROM AUTHOR]

Fabry disease (FD) is a rare genetic disorder that affects various organs and systems in the body. The disease is caused by a deficiency in the lysosomal enzyme α-galactosidase A (AGAL), which leads to the accumulation of globotriaosylceramide (Gb3) within lysosomes. This accumulation can cause damage to cells and organ systems, leading to a wide range of symptoms and complications. FD is a heterogeneous disorder, with a wide range of clinical phenotypes, ranging from the classic form, which is severe and associated with early onset, to milder non-classical forms, which are often limited to one organ and manifest later in life. We describe the case of a 23-year-old FD patient who was admitted as an emergency transfer due to newly discovered severe aortic regurgitation and suspected aortic valve endocarditis with vegetations of high embolic potential. Three years ago, the patient underwent a living donor kidney transplantation—the kidney graft lost its function 1 year after transplantation, and a chronic hemodialysis program was reinstituted.

Septal myectomy is the gold standard treatment option for patients with obstructive hypertrophic cardiomyopathy whose symptoms do not respond to medical therapy. This operation reliably relieves left ventricular outflow tract gradients, systolic anterior motion of the mitral valve, and associated mitral valve regurgitation. However, there remains controversy regarding the necessity of mitral valve intervention at the time of septal myectomy. While some clinicians advocate for concomitant mitral valve procedures, others strongly believe that the mitral valve should only be operated on if there is intrinsic mitral valve disease. At Mayo Clinic, we have performed septal myectomy on more than 3000 patients with obstructive hypertrophic cardiomyopathy, and in our experience, mitral valve operation is rarely necessary for patients who do not have intrinsic mitral valve disease such as leaflet prolapse or severe calcific stenosis. In this paper, we review anatomical considerations, imaging, and surgical approaches in the management of the mitral valve in hypertrophic cardiomyopathy. [ABSTRACT FROM AUTHOR]

Mitral valve repair for patients with degenerative or functional mitral valve regurgitation improves symptoms and prognosis, and several techniques have been described. Important principles in operation are simplicity, reproducibility, and durability of repair. At Mayo Clinic, we have operated on more than 6000 patients with degenerative mitral valve disease and valve prolapse, and this review details our approach to mitral valve repair, including robotic and minimally invasive techniques. Most patients with isolated leaflet prolapse can be managed with leaflet plication or triangular resection, and chordal replacement is reserved for repair of anterior leaflet prolapse. Posterior annuloplasty with a standard-sized flexible band is used to reduce annular circumference and improve leaflet coaptation. With these methods, early risk of mortality for mitral valve repair is low in the current era (< 1%), and rate of recurrent valve leakage is 1.5 per 100 patient-years during the first year post-repair and 0.9 per 100 patient-years thereafter. This paper also briefly summarizes important considerations for patients with mitral valve regurgitation and severe calcification, perforations due to endocarditis, and rheumatic heart disease.

Fat deposition in the left ventricle in patients without proven myocardial diseases has not been sufficiently investigated. In this paper, a case of diffuse and patchy intramyocardial fat deposition in the left ventricular myocardium in a patient with no cardiac disease history has been detected by cardiac magnetic resonance imaging (CMRI). Such a finding would not be considered a usual cardiomyopathy and further studies are needed to investigate its prevalence, pathophysiological mechanisms, and prognosis. [ABSTRACT FROM AUTHOR]

Totally endoscopic coronary artery bypass (TECAB) surgery can exclusively be undertaken with the aid of operative robots. In the past two decades, surgical remote manipulator systems—predominantly the daVinci® devices—have brought us the reality of endoscopic internal mammary artery harvesting and coronary bypass anastomoses via minimally invasive thoracic port access. Single up to quadruple TECAB interventions are recently feasible; the procedure can be delivered either as beating heart applying endoscopic vacuum stabilizer or under cardioplegic arrest on heart-lung machine. Significant surgical team learning curves are involved in a stepwise development of these complex procedures, including intense dry- and wet-lab trainings, endoscopic internal mammary artery harvesting and manual coronary anastomosis building through a thoracotomy. Increasing number of papers have been published regarding clinical TECAB series in the past decade. In arrested heart TECAB procedures on cardiopulmonary bypass, the conversion rate from port access to larger thoracic incision measures 15.1% and no perioperative mortality is observed in published records. Stroke, kidney failure and atrial fibrillation rates stay at 0.6, 0.4 and 12.9%, respectively. Analysis of beating heart TECAB procedures revealed a conversion rate of 15.3%, perioperative mortality 0.4%, stroke 0.3%, kidney failure 0.6% and atrial fibrillation 9.2%. Additionally, due to the obviously smaller surgical trauma, a remarkable fast return to normal daily activities can be demonstrated in clinical series of robotic assisted coronary bypass surgery. Short-term freedom of major adverse cardiac and cerebral events (MACCE) stays over 90%. Long-term studies reveal 5-year freedom of MACCE in the 75.2 to 83.1% range. Nowadays, total endoscopic coronary artery bypass grafting is a feasible and reproducible surgical method. Advanced hybrid coronary interventions offer complex multivessel TECAB with support of percutaneous coronary interventions (PCI). Combination of the above techniques widens the spectrum of minimally invasive therapeutic solutions concerning multivessel procedure including bilateral internal mammary grafts and drug-eluting stents.

The aortic root is the segment of the aorta between the left ventricular outflow tract and the sinotubular junction of the ascending aorta, and, on one level, is merely a tube, with a valve at its base, dynamic structures below it, and notable for having the life-limiting coronary arteries originate within its sinuses. However, we propose that the perception of the aortic root has been historically grossly over-simplified by virtue of a bias towards its internal aspect, in terms of coronary ostia and subvalvar relationships through the fibrous skeleton and in so-doing a myocardial component on the external aspect has all but been ignored. This myocardial mass, a component of the left ventricular free wall, is sometimes termed the 'left ostial process' but appears to be rarely, if ever, considered by anatomists, cardiologists, and surgeons alike. By virtue of its direct continuity to the aortic root and proximal left coronary artery, it may have unique roles and, at the very least, deserves greater recognition and investigation. Herein, we propose that it could play a crucial role in cardiac embryology including coronary dominance, and may afford a physiological advantage, to the extent that it may have been selected for in evolutionary terms.

Background: The introduction of endoscopic saphenous vein harvesting (ESVH) has been reported to reduce wound pain and infection, compared with open saphenous vein harvesting (OSVH) techniques. There are still controversies regarding this technique. The aim of our study is to investigate the endothelial preservation of saphenous vein (SV) grafts harvested by different techniques. Further observations were made for harvesting and closure time, incision length and effect of pressure distension of the veins to the vein endothelium. Methods: Prospective observational study of sixty human saphenous vein grafts was performed to evaluate endothelial preservation by haematoxylin–eosin and Cluster of Differentiation 31 (CD 31) staining. Saphenous vein was harvested endoscopically either by closed CO2 (carbon dioxide) ESVH, open CO2 ESVH or OSVH harvesting technique. Demographic data and intra-operative data were collected. Two saphenous vein samples were collected from each patient to compare differences before and after distension of the veins. Both haematoxylin–eosin and immunohistochemistry slides were imaged by a high-resolution slide scanning system. Results: Open CO2 ESVH group showed the highest number of endothelial detachments. Mean scoring of the immunohistochemistry method using the CD31 antibody was much lower in the open CO2 ESVH group (33.25% ± 28.71, P < 0.0003). This represents a more poorly preserved endothelial cells in the Open CO2 ESVH than the closed CO2 ESVH. Closure time and incision lengths were significantly shorter in both ESVH groups compared to the OSVH group. Significant low scores of immunohistochemistry for samples were seen in distended veins (39.0% ± 30.08, p = 0.004). The OSVH in random sample B, which represents the conduit that will be used, had a far better endothelium preservation and less endothelial detachment when compared to ESVH. Conclusion: We observed more endothelial detachment in the open CO2 ESVH group, due to lack of subcutaneous tissue separation, poor visualization and traction stress across the wall of the saphenous vein. The closed CO2 ESVH group had more endothelial cells preserved, but the OSVH group fared the best with the least number of endothelial cell detachment and a higher score of CD31 antibody.

Background: This study aimed to examine the prevalence of gender bias in the field of cardiothoracic vascular surgery in India and compared women surgeons and trainees in India and abroad. Methods: This was a comparative, cross-sectional analytical study using an online questionnaire. The survey included questions about demographics, career choice, training, academic and leadership opportunities, and the impact of choosing cardiothoracic-vascular surgery as a career on personal life. Results: A total of 203 practicing surgeons and trainees participated in the study and included 121 (59.6%) men and 82 (40.3%) women. Out of the 82 women, 48 (58.5%) were from India, and 34 (41.5%) were from other countries. Satisfaction with the specialty was similar among men and women (105 (86.7%) vs. 68 (82.9%), p = 0.44 respectively). Majority (n = 30, 62.5%) of the female surgeons in India reported being discriminated against, as well as receiving favored treatment 11 (22.9%). Compared to men, women surgeons in India were more frequently advised against pursuing a career in cardiothoracic and vascular surgery (p < 0.001) and were more frequently subjected to gender-related references (p < 0.001). In addition, they had fewer presentation opportunities (p = 0.016) at national or regional meetings during their training compared to men. Additionally, 50% (24) of the women in India reported being single, in contrast to 7% (6) of men, and only 15 (31.3%) women reported having a child, compared to 57 (66.3%) of the men. Conclusion: The study revealed significant gender disparities within the field of cardiothoracic vascular surgery in India and highlights the urgent need to address gender disparities and bias in cardiothoracic vascular surgery.

In modern scientific literature, the dominant role of statistical rigor is undeniable. However, the methodology and the language behind this science is often forbidding and not surgeon friendly and hence often forces the average reader to skim through the details and jump to the conclusions section and if the P value is reported to be statistically significant, we regard the conclusions as valid.However, if we make friends with statistical techniques and try to understand it,the results can be gratifying. A surgeon having the ability to do his/her own analysis has a very powerful weapon on hand. Not just in publications but in actually improving outcomes of patient care. [ABSTRACT FROM AUTHOR]

Introduction and objective: Foreign body getting lodged in esophagus is quite common, commonly due to ingestion of coin, pin, fish bone and meat. But accidental ingestion of artificial denture is a less often found condition. This paper studies the etiology, management, complications and final outcome of denture obstructing the esophagus. Material and methods: Fourteen patients with denture esophagus were reviewed retrospectively, admitted between Jan 2012 to Oct 2016. The clinical presentations, cause of the denture ingestion, radiological findings, surgical intervention, complication and final outcome were studied. Most common site of impaction is crico pharynx junction. Denture was removed by cervical incision in all cases. Post-operatively ryles tube was kept routinely in all patients and gastrograffin swallow was performed. After mandatory follow up of one year, patients were followed as and when needed. Results: All the patients presented with complaint of difficulty in swallowing. Five of them also had pain in neck and fever. Cause of denture ingestion was found to be very old denture, fitted by quacks, which they did not change for years. Hence they get loose and accidentally got ingested during sleeping or with the meal. Intra-operatively posterior esophageal wall ruptured in 3 cases for which repair was performed. All patients had severe periesophagitis. Post-operatively 3 patients developed esophagocutaneous fistula. Post-operative stricture was not seen in any case. Conclusion: Early surgical intervention is must to prevent complications. Sharp metallic wires in esophagus prevent their endoscopic removal. They should be regularly changed, before they get loose. Denture implants should be done by qualified dentists only. [ABSTRACT FROM AUTHOR]

The treatment of aortic arch pathologies is becoming progressively more complex and multidisciplinary. Despite progresses in open surgical techniques, the high rate of surgical morbidity and mortality, especially in frail and elderly patients, has led to the development of alternative treatment options to conventional open surgery such as hybrid and endovascular procedures. Our purpose is to summarize the advantages and disadvantages of the different approaches and investigate the role of a dedicated aortic team in the choice of the most appropriate treatment for each patient.

The Impella 5.5 (Abiomed) is a percutaneous, temporary left ventricular assist device (LVAD) that serves as an important method of treatment of acute cardiogenic shock refractory to medical management. The Impella 5.5 and 5.0 are commonly inserted through the right axillary artery; however, this may be limited by inadequate vessel diameter to accommodate the Impella and inadequate vessel quality. A central approach to Impella 5.5 incision has been described in the pediatric population, particularly via the innominate artery through a suprasternal and/or neck incision, with success. As an alternative to axillary Impella placement, we propose the usage of a limited suprasternal incision for Impella 5.5 insertion in the adult population, either through the proximal right subclavian artery or the distal innominate artery. This may offer multiple advantages, such as increased vessel diameter and quality of more proximal vessels, avoidance of partial sternotomy, avoidance of a second infraclavicular wound site if the patient progresses to require LVAD or transplant, avoidance of lymphatic and nerve injury through the axillary exposure, ease of manipulation for repositioning, and patient rehabilitation. Potential limitations include difficulty due to body habitus, potential risk of stroke with the innominate approach, and wound complications. A central approach is a reasonable alternative to axillary Impella placement in patients with inadequate axillary artery caliber, defined as less than 6–7 mm diameter, poor artery quality to accommodate anastomosis, and small body habitus, allowing for ease of exposure.

Infective endocarditis surgical patients suffer from high rates of severe complications such as systemic inflammatory response, septic shock, and multi-organ failure leading to high mortality. Systemic inflammatory response based on cytokines as messengers plays an important role in these patients. The concept of intraoperative haemoadsorption has been proposed to remove such elevated cytokines in patients undergoing cardiac surgery for infective endocarditis. Haemoadsorption offers the possibility to stabilise haemodynamics, reduce sepsis-related mortality, and protect organ function. However, until now, there has been no general opinion and consensus regarding the clinical effectiveness of adjunctive intraoperative haemoadsorption in infective endocarditis. Therefore, we reviewed the current literature evaluating haemoadsorption in infective endocarditis patients undergoing cardiac surgery. The review was registered at PROSPERO (CRD42023457632).

Purpose: Adenoid cystic carcinoma (ACC) of the trachea is a rare malignancy. We report a patient with ACC who underwent multimodal management including tracheal resection. A systematic review was also conducted on tracheal resection for ACC. Methods: A literature search was conducted on MEDLINE, Embase, and PubMed using the search terms "trachea AND adenoid cystic carcinoma AND (surgery OR resection)" and articles from 2000 to August 2021 were identified. A total of 29 journal articles were included in the review. Results: A total of 403 patients underwent surgery for tracheal ACCs. The mean age was 48.1 years and 54.7% were female. The commonest anatomical location was the lower trachea (46.9%). The mean time from symptom onset to diagnosis was 16.6 months with the commonest symptom being dyspnoea (52%). Fifty-eight percent of the patients had intraluminal growth. Tracheal resection (46.2%) and access via thoracotomy (41.4%) were the commonest procedures described. The mean length of trachea resected was 39.2 mm and the mean tumour size was 31.5 mm. 16.8% of lymph nodes were involved and 73.8% of cases had positive resection margins. The overall complication rate was 1.4–5.4% and the in-hospital mortality rate was 9.8%. The overall survival reported was 61.7% at 5 years and 54.6% at 10 years. Conclusion: Surgical resection followed by adjuvant radiotherapy is the mainstay in the treatment of tracheal ACC, notwithstanding the high rates of involved margins. Achieving tension-free anastomosis should be the first priority given the favourable response of adjuvant therapies in reducing recurrence rate and improving overall survival. [ABSTRACT FROM AUTHOR]
