Background & aim: Macro policies in the field of health tourism should be designed and implemented taking into account the facilities and environmental resources in order to provide a good opportunity to provide quality medical services to foreign patients referring to the country and create their satisfaction. The purpose of the present study was to identify and prioritize the factors affecting the management of health tourism development in Fars province. Methods: The present qualitative-exploratory study was conducted in 2019. 20 experts active in the field of health tourism were selected by purposive sampling method with maximum diversity. After obtaining informed consent from the participants, the research data were collected by semi-structured in-depth interview method and then recorded in Maxqda-10 software and analyzed using directional and summary composite content analysis. In this method, the units of analysis in each step were the paragraphs recorded by the researcher in the process of interviewing the participants. During the content analysis process, different codes were first reviewed, then grouped into subcategories, and finally 70 subcategories and 23 main categories. The five themes of structural, behavioral, environmental, conservation and development were integrated. The collected data were analyzed using paired comparison matrix test with hierarchical analysis process. Results: The results of the present study revealed that the factors affecting the management of health tourism development in Fars province consist of 5 main categories including: structural factors, development and optimization, environmental, behavioral, and protective. The relative weights identified for each of these factors were 0.512, 0.276, 0.128, 0.053 and 0.032, respectively. Conclusion: Structural, developmental and optimization, environmental, behavioral, and conservation factors had relative weight and significant incompatibility rates for health tourism development management. Therefore, the results of the present study inform high-level decision makers where and how to focus their efforts and resources to have the maximum impact on the management of health tourism development at the local and national levels.

Background & aim: Performance Indicators consist of standards, evaluation tools and identifications to check current situations in organizations. Hospitals as the center of gravity to provide health and therapy care are of no exception. The present study aimed to determe the performance indicators in selected hospitals of Tehran province. Methods: The present inquiry was a cross-sectional descriptive-analytical study. The statistical population of all public hospitals was covered by Tehran University of Medical Sciences and Shahid Beheshti. 14 educational and 9 non-educational cases were examined. Data collection tools were data entry forms for hospital performance indicators, which included general information on the studied hospitals and performance indicators, bed occupancy rate, average patient stay, and bed turnover rate. Data were analyzed using Chi-square and Kolmogorov-Smirnov tests. Results: The average patient stay was 5.89 days, which was only 7.15 percent desirable by standards. The bed occupancy rate was 76.35 and the bed turnover was 45.97 times a year. The status of these two indicators was optimal based on the standards available in 92.85% of the cases. Also, based on the results of the present study, the mean average patient stay was 2.91 days, which was desirable in 77.77% of the cases according to the standards. The bed occupancy rate was 62.70 and only 11.11% of the cases were favorable. The bed turnover was set at 65.44 times a year. In relation to this index, in 100% of cases, the situation was favorable. Conclusion: The non-educational hospitals of Tehran University of Medical Sciences were in a better position regarding the length of the patientchr('39')s stay than the indicators of the Ministry of Health and even compared to the hospitals of other provinces. In relation to educational hospitals, due to the fact that according to the Ministry of Health, the optimal condition of the average patient stay is less than 3.5 days and more than 4 days is a sign of weakness and inefficiency of the hospital, the studied hospitals with an average of 5.69 days. They differ significantly from the standard. In the other two indicators, both educational and non-educational hospitals were in good condition.

Abstract Background & aim: Awareness about the different aspects of health during puberty plays an important role in the health of girls and finally on their health future pregnancy. The aim of the present study was to to compare the effect of role playing and classical training methods in the the improvement of puberty health among secondary school girls in Yasouj City, Iran. Methods: In this study, the educational need during puberty school girls in the interview was determined. The two schools girls were randomly selected (students any school-60). Next, a knowledge and attitude questionnaire and a behavior checklist related to the main puberty health problems were completed. Then one of the schools randomly was selected as educational interventions schools and other were studied as controls. After grouping the students into four groups of 15, intervention were conducted in four sessions including: role-play, question and answer, and lecture. In the control group, all number of school students received training on puberty health through a classical education (lectures). The results were subsequently compared. Data were analyzed by Student t-test paired t-test, and analysis of variance. Results: The results of this study showed that the level of knowledge, attitude and behavior related to health matters during puberty showed significant improvement in the girls before and after implementation of educational intervention through role play (p

Abstract Background & aim: MRI is a new and expensive diagnostic technology which has been increasingly used globally. This aim of study was to determining the administration of MRI for the Lumbar vertebrae using the appropriate RAND Method. Methods: This qualitative study was based on consensus. The population study included 9 professionals involved in prescribing the procedure based on Rand. Two criteria were identified: Valid clinical guidelines and expert opinion. Scoring criteria were the numbers 1 to 9. Numbers in the range of 1 to 3 unfit, 4 to 6, unreliable, and 7 to 9, placed in an appropriate range. An agreement was done when 7 specialists agreed marked the same range. Results: 97 scenarios were selected for the lumbar spine MRI in the extracting phase. 18 other scenarios were added by panel members. Finally, a total of 115 scenarios were identified. After implementing two rounds, the scenarios were categorized into three ranges. Sixty eight (%59.1) of the scenarios were considered as appropriate, 44(%38.2) as uncertain, and 3(%2.6) as inappropriate. Conclusion: A developed scenario in this project for MRI lumbar vertebrae treated with Guide is perfect for specialists. It is recommended that insurance companies and other institutions use this as a benchmark for the payment of MRI lumbar vertebrae fees. RAND appropriateness Method is useful for identifying stakeholder views in settings with limited resources. Key words: Lumbar Spine, Low Back Pain, RAND Appropriateness Method

ABSTRACT: Introduction & Objective: Results of different studies show that a relatively large number of healthcare services offered are inappropriate or unnecessary. Benign prostatic hyperplasia is a benign enlargement of the prostate gland. Clinical features of this disease are one of the most common problems encountered by elderly males. The aim of this study was to assess the appropriateness of benign prostatic hyperplasia surgery. Materials & Methods: In this qualitative study which was conducted in 2008-9, in Tehran University of Medical Sciences, the RAN/UCLA method was used, which was designed in 1980 by the RAND institute and the University of California in Los Angeles. Regarding the stages of our method, scenarios and indications for benign prostatic hyperplasia surgery were chosen from the latest approved scientific resources and subsequently sent to urology specialists, who were chosen as members of the specialized panel. Panel members gave scores ranging from 1 to 9 to each indication and scenario based on scientific resources, clinical experiences and patient’s condition in two separate panel sessions. After compilation, the indications were finally grouped as appropriate, equivocal, and inappropriate so that they could be used to determine appropriateness of benign prostatic hyperplasia surgery in hospitals. In this study, the most suitable and most approved clinical guidelines related to benign prostatic hyperplasia, the Guidelines Evaluation and Research Appraisal (AGREE) were used.The selected guidelines were used as scientific resources for choosing the indications of benign prostatic hyperplasia surgery. SPSS version 16 and kappa weighted value were used in analysis process of the study. Results: Out of 282 scenarios grouped as 9 conditions related to benign prostatic hyperplasia surgery, which were extracted from scientific sources, 73 cases (25.9%) were considered as appropriate, 14 cases (5%) as equivocal and 7 cases (2.5%) were considered as inappropriate. Also 22 cases (7.8%) were considered as appropriate indications for drug therapy and none were found to be suitable for waiting and watching. There were 94 scenarios related to surgery that 75 scenarios (80%) were grouped in appropriate and 8 scenarios (8.5%) identified inappropriate. Conclusion: At the present time, due to the lack of scientific evidence for suitable decision-making in providing health services, methods based upon agreement, including the one used in the present study, and the use of treatment standards derived from similar studies, are amongst the most important measures taken to improve the standard of health, provide suitable health services, and to reduce unnecessary costs. In addition, RAM appropriateness method could be an ideal method in determining the appropriateness of health care and in reducing the rate of inappropriate services provided. The similarity of results derived from other studies performed by the RAND method in determining the appropriateness of benign prostatic hyperplasia treatment with the current study shows the validity and reliability of this method. Keywords: Appropriate criteria, Benign Prostatic Hyperplasia (BPH), Appraisal of Guidelines for Research and Evaluation (AGREE).

Objective:  Endocarditis as a potentially life-threatening disease with high complication and mortality rates. In recent years, an increase in the incident of endocarditis has been reported throughout Europe. In the aging society, successful treatment is complex and challenging owing to the high rate of multimorbidity., Methods:  We initiated a statewide prospective multicenter endocarditis registry in 2020. Perioperative risk factors, comorbidities, microbiological, laboratory and imaging diagnostics, complications, and mortality including 1-year follow-up were collected. The present midterm analysis includes factors influencing mortality in the first 313 patients., Result:  In-hospital mortality and 1-year mortality were 28.4 and 40.9%, respectively. Preoperative risk factors include age ( p  < 0.001), EuroSCORE II ( p  < 0.001), coronary artery disease ( p  = 0.022), pacemaker probe infection ( p  = 0.033), preoperative left ventricular ejection fraction (LVEF), systemic inflammatory response syndrome (SIRS), pulmonary edema, heart failure, septic emboli, acute renal failure, impaired coagulation, hypalbuminemia ( p  < 0.001), and N-terminal prohormone of brain natriuretic peptide (NTproBNP) ( p  = 0.001). The presence of peri-annular abscess, perforation, and shunt were associated with increased mortality ( p  = 0.004, 0.001, and 0.004, respectively). In addition, cardiopulmonary bypass time influenced mortality ( p  = 0.002). The main postoperative causes of death were multi-organ failure, renal failure, vasoplegia, and low-output syndrome ( p  < 0.001). Previous endocarditis was 7.7%, while 35.5% were prosthetic valve recipients and 33.6% were redo surgeries., Conclusion:  Our first registry data show the complexity of endocarditis patients and the challenging treatment. Some risk factors can be treated preoperatively. For instance, hypalbuminemia and the duration of the procedure can be controlled with adequate albumin substitution and carefully planned procedures restricted to the essential requirements, that is, hybrid approaches with consecutive interventions., Competing Interests: None declared., (Thieme.

Background:  The increasing presence of female doctors in the field of cardiac surgery has raised questions about their surgical quality compared to their male colleagues. Despite their success, female surgeons are still underrepresented in leadership positions, and biases and concerns regarding their performance persist. This study aims to examine whether female surgeons perform worse, equally well, or better than their male counterparts in commonly performed procedures that have a significant number of female patients., Method:  A retrospective cohort of patients from 2011 to 2020 who underwent isolated coronary artery bypass graft (CABG) and aortic valve surgery was studied. To compare the surgical quality of men and women, a 1:1 propensity score matching (two groups of 680 patients operated by men and women, respectively, factors: age, logarithm of EuroSCORE (ES), elective, urgent or emergent surgery, isolated aortic valve, or isolated CABG) was performed. Procedure time, bypass time, x-clamp time, hospital stay, and early mortality were compared., Results:  After propensity score matching between surgeons of both sexes, patients operated by males (PoM) did not differ from patients operated by females (PoF) in mean age (PoM: 66.72 ± 9.33, PoF: 67.24 ± 9.19 years, p  = 0.346), log. ES (PoM: 5.58 ± 7.35, PoF: 5.53 ± 7.26, p  = 0.507), or urgency of operation (PoM: 43.09% elective, 48.97% urgent, 7.94% emergency, PoF: 40.88% elective, 55.29% urgent, 3.83% emergency, p  = 0.556). This was also the case for male and female patients separately. Female surgeons had higher procedure time (PoM: 224.35 ± 110.54 min; PoF: 265.41 ± 53.60 min), bypass time (PoM: 107.46 ± 45.09 min, PoF: 122.42 ± 36.18 min), and x-clamp time (PoM: 61.45 ± 24.77 min; PoF: 72.76 ± 24.43 min). Hospitalization time (PoM: 15.96 ± 8.12, PoF: 15.98 ± 6.91 days, p  = 0,172) as well as early mortality (PoM: 2.21%, PoF: 3.09%, p  = 0.328) did not differ significantly. This was also the case for male and female patients separately., Conclusion:  Our study reveals that in routine heart surgery, the gender of the surgeon does not impact the success of the operation or the early outcome of patients. Despite taking more time to perform procedures, female surgeons demonstrated comparable surgical outcomes to their male counterparts. It is possible that women's inclination for thoroughness contributes to the longer duration of procedures, while male surgeons may prioritize efficiency. Nevertheless, this difference in duration did not translate into significant differences in primary outcomes following routine cardiac surgery. These findings highlight the importance of recognizing the equal competence of female surgeons and dispelling biases regarding their surgical performance., Competing Interests: None declared., (The Author(s).

(1) Background: Polymeric heart valves are prostheses constructed out of flexible, synthetic materials to combine the advantageous hemodynamics of biological valves with the longevity of mechanical valves. This idea from the early days of heart valve prosthetics has experienced a renaissance in recent years due to advances in polymer science. Here, we present progress on a novel, 3D-printable aortic valve prosthesis, the TIPI valve, removing the foldable metal leaflet restrictor structure in its center. Our aim is to create a competitive alternative to current valve prostheses made from flexible polymers. (2) Methods: Three-dimensional (3D) prototypes were designed and subsequently printed in silicone. Hemodynamic performance was measured with an HKP 2.0 hemodynamic testing device using an aortic valve bioprosthesis (BP), a mechanical prosthesis (MP), and the previously published prototype (TIPI 2.2) as benchmarks. (3) Results: The latest prototype (TIPI 3.4) showed improved performance in terms of regurgitation fraction (TIPI 3.4: 15.2 ± 3.7%, TIPI 2.2: 36.6 ± 5.0%, BP: 8.8 ± 0.3%, MP: 13.2 ± 0.7%), systolic pressure gradient (TIPI 3.4: 11.0 ± 2.7 mmHg, TIPI 2.2: 12.8 ± 2.2 mmHg, BP: 8.2 ± 0.9 mmHg, MP: 10.5 ± 0.6 mmHg), and effective orifice area (EOA, TIPI 3.4: 1.39 cm 2 , TIPI 2.2: 1.28 cm 2 , BP: 1.58 cm 2 , MP: 1.38 cm 2 ), which was equivalent to currently used aortic valve prostheses. (4) Conclusions: Removal of the central restrictor structure alleviated previous concerns about its potential thrombogenicity and significantly increased the area of unobstructed opening. The prototypes showed unidirectional leaflet movement and very promising performance characteristics within our testing setup. The resulting simplicity of the shape compared to other approaches for polymeric heart valves could be suitable not only for 3D printing, but also for fast and easy mass production using molds and modern, highly biocompatible polymers.

Background and Objectives: Jehovah's Witnesses (JW) reject the transfusion of blood components based on their religious beliefs, even if they are in danger of harm or death. In cardiac surgery, this significantly reduces the margin of safety and leads to ethical conflicts. Informed consent should be carefully documented and the patient's family should be involved. This study aims to compare the postoperative course of JW who underwent major cardiac surgery with a similar population of non-Witnesses (NW)., Patients and Methods: Demographic, procedural, and postoperative data of all consecutive JW who underwent cardiac surgery at our institution were obtained from the records. They were compared with a propensity-score-matched group of NW. Anemic JW were treated with erythropoietin and/or iron as needed. Cardiac surgery was performed by experienced surgeons using median sternotomy and cardiopulmonary bypass. Common blood-sparing techniques were routinely used. Periprocedural morbidity and mortality were statistically evaluated for both groups., Results: A total of 32 JW and 64 NW were part of the matched dataset, showing no demographic or procedural differences. EPO was used preoperatively in 34.4% and postoperatively in 15.6% of JW but not in NW. Preoperative hemoglobin levels were similar (JW, 8.09 ± 0.99 mmol/L; NW, 8.18 ± 1.06; p = 0.683). JW did not receive any transfusions except for one who revoked, while NW transfusion rates were 2.5 ± 3.1 units for red cells ( p < 0.001) and 0.3 ± 0.8 for platelets ( p = 0.018). Postoperative levels differed significantly for hemoglobin (JW, 6.05 ± 1.00 mmol/L; NW, 6.88 ± 0.87; p < 0.001), and hematocrit (JW, 0.29 ± 0.04; NW, 0.33 ± 0.04; p < 0.001) but not for creatinine. Early mortality was similar (JW, 6.3%; NW, 4.7%; p = 0.745). There were more pacemakers and pneumonias in JW, while all other postoperative conditions were not different., Conclusions: Real-world data indicate that Jehovah's Witnesses can safely undergo cardiac surgery provided that patients are preconditioned and treated by experienced surgeons who use blood-saving strategies. Postoperative anemia is observed but does not translate into a worse clinical outcome. This is consistent with other studies. Finally, the results of this study suggest that all patients should benefit from optimal pretreatment and blood-sparing strategies in cardiac surgery, not just Jehovah's Witnesses.

Objective: According to our nationwide registry, total numbers of surgical aortic valve implantation (sAVR) are constantly declining, while transcathether aortic valve implantation (TAVI) indications are widened toward intermediate- and low-risk patients. So, is there still room for conventionally implanted valves? Can results compete with TAVI or will sAVR be marginalized in the near future?, Methods: Between 2011 and 2019, 1,034 patients (67.1% male, mean = 72.2 years) were enrolled receiving stented biological valves with or without concomitant coronary artery bypass grafting (CABG), atrial ablation, or wrapping of the ascending aorta. Odds ratios for the early and late mortality were calculated regarding comorbidities as potential risk factors. Statistical analysis was performed using SPSS., Results: Overall, early mortality (EM) was 6.1%, 1-year mortality was 11.2%, and 5-year mortality was 19.9%. In low-risk patients (EuroSCORE II <4%), it was 1.0, 2.7, and 9.3%. Incidence of EM was significantly increased following decompensation, prosthetic valve, pacemaker carrier, dialysis, and pulmonary hypertension. Postoperative complications, such as systemic inflammatory response syndrome (SIRS), sepsis, multiorgan failure, hepatic failure, dialysis, gastrointestinal bleeding, and ileus, also increased EM. Late mortality was significantly increased by dialysis, hepatic cirrhosis, infected port system, aortic valve endocarditis, prosthetic valve carrier, and chronic hemodialysis., Conclusion: Conventionally implanted aortic valves do well early and late. The fate of the patient is dependent on individual risk-factors. Particularly, in low-risk patients, sAVR can compete with TAVI showing overall good early, as well as late results being even superior in some important aspects such as pacemaker implantation rate. Thus, the time is yet not ripe for TAVI to take over primary indications for AVR in low-risk patient., Competing Interests: None declared., (Thieme. All rights reserved.)

Background  Prosthetic valve endocarditis is becoming more common because many patients live long enough to experience bacteremia, while insufficient antibiotic prophylaxis eventually leads to graft infection. Valve-bearing conduit infections are the most feared because of technical challenges. Case Description  Two young patients were coincidental twins in terms of diagnosis and therapy. Both underwent complete replacement of the conduit, aortic arch prosthesis, and additional strategies to reconnect the coronary ostia and the brachiocephalic trunk. Both were discharged without significant residual problems. Conclusion  Even most demanding infectious problems can be solved. Thus, surgery should not be denied., Competing Interests: Conflict of Interest None declared., (The Author(s).

Objective: The aim of this study was to investigate the relationship between age and sex in regard to the development of deep sternal wound infections and sternal instability following median sternotomy., Methods: A propensity-score-matching analysis was conducted on 4505 patients who underwent cardiac surgery between 2009 and 2021, all of whom had a BMI of ≥30 kg/m 2 . A total of 1297 matched pairs were determined in the sex group, and 1449 matched pairs we determined in the age group. The distributions of sex, age, diabetes mellitus, delirium, unstable sterna, wire refixation, wire removal, superficial vacuum-assisted wound closure, deep vacuum-assisted wound closure, clamp time, bypass time, logistic EuroSCORE, and BMI were determined., Results: The 30-day in-hospital mortality was found to be similar in the older and younger groups (8.149% vs. 8.35%, p = 0.947), and diabetes mellitus was also equally distributed in both groups. However, postoperative delirium occurred significantly more often in the older group (29.81% vs. 17.46%, p < 0.001), and there was a significantly higher incidence in men compared with women (16.96% vs. 26.91%, p < 0.001). There were no differences found in the incidence of sternum instability, fractured sternum, superficial vacuum-assisted wound closure, and deep vacuum-assisted wound closure between the age and sex groups., Conclusions: In conclusion, this study found that sternal instability and deep-wound-healing problems occur with equal frequency in older and younger patients and in men and women following median sternotomy. However, the likelihood of postoperative delirium is significantly higher in older patients and in men. These findings suggest that a higher level of monitoring and care may be required for these high-risk patient groups to reduce the incidence of postoperative delirium and improve outcomes following median sternotomy.

Objective: Advanced age is a risk factor in cardiac surgery contributing significantly to a worse outcome. The reasons are frailty and multimorbidity. In this study, we asked: Is there an aging of the heart which differs from chronological age?, Methods: Propensity score matching was performed between 115 seniors ≥ 80 years and 345 juniors < 80 years. After the patients were found to be comparable in terms of cardiac and noncardiac disease and risk profiles, they were further analyzed for cardiac parameters. In addition, the seniors and juniors were compared in terms of cardiac health and postoperative outcome. Furthermore, the patients were subdivided into several age groups (<60 years, 60-69 years, 70-79 years, and >80 years) and compared regarding outcome., Results: The seniors demonstrated significantly lower tricuspid annular plane systolic excursion (TAPSE), significantly more frequent diastolic dysfunction, significantly higher plasma levels of NT-proBNP, and significantly larger left ventricular end-diastolic and end-systolic diameters and left atrial diameters ( p < 0.001, respectively). Furthermore, in-hospital mortality and most postoperative complications were significantly higher in seniors compared with juniors. While old cardiac healthy patients showed better outcome than old cardiac aged patients, the outcome from young cardiac aged patients was better than old cardiac aged patients. The outcome and survival deteriorated with increasing life decades., Conclusions: The elderly suffer significantly more from cardiac deterioration, i.e., cardiac aging, and show higher multimorbidity. Mortality risk is significantly higher and they suffer more often from a complicated postoperative course compared to younger patients. Further approaches to prevention and treatment of cardiac aging are needed to address the needs of an aging society.

Background: Frailty is gaining importance in cardiothoracic surgery and is a risk factor for adverse outcomes and mortality. Various frailty scores have since been developed, but there is no consensus which to use for cardiac surgery., Methods: In an all-comer prospective study of patients presenting for cardiac surgery, we assessed frailty and analyzed complication rates in hospital and 1-year mortality, as well as laboratory markers before and after surgery., Results: 246 included patients were analyzed. A total of 16 patients (6.5%) were frail, and 130 patients (52.85%) were pre-frail, summarized in the frail group (FRAIL) and compared to the non-frail patients (NON-FRAIL). The mean age was 66.5 ± 9.05 years, 21.14% female. The in-hospital mortality rate was 4.88% and the 1-year mortality rate was 6.1%. FRAIL patients stayed longer in hospital (FRAIL 15.53 ± 8.5 days vs. NON-FRAIL 13.71 ± 8.94 days, p = 0.004) and in intensive/intermediate care units (ITS/IMC) (FRAIL 5.4 ± 4.33 days vs. NON-FRAIL 4.86 ± 4.78 days, p = 0.014). The 6 min walk (6 MW) (317.92 ± 94.17 m vs. 387.08 ± 93.43 m, p = 0.006), mini mental status (MMS) (25.72 ± 4.36 vs. 27.71 ± 1.9, p = 0.048) and clinical frail scale (3.65 ± 1.32 vs. 2.82 ± 0.86, p = 0.005) scores differed between patients who died within the first year after surgery compared to those who survived this period. In-hospital stay correlated with timed up-and-go (TUG) (TAU: 0.094, p = 0.037), Barthel index (TAU-0.114, p = 0.032), hand grip strength (TAU-0.173, p < 0.001), and EuroSCORE II (TAU 0.119, p = 0.008). ICU/IMC stay duration correlated with TUG (TAU 0.186, p < 0.001), 6 MW (TAU-0.149, p = 0.002), and hand grip strength (TAU-0.22, p < 0.001). FRAIL patients had post-operatively altered levels of plasma-redox-biomarkers and fat-soluble micronutrients., Conclusions: frailty parameters with the highest predictive value as well as ease of use could be added to the EuroSCORE.

Background: Cardiac tumors are rare, with a low incidence of between 0.0017 and 0.19%. The majority of cardiac tumors are benign and predominantly occur in females. The aim of our study was to examine how outcomes differ between men and women., Methods: From 2015 to 2022, 80 patients diagnosed with suspected myxoma were operated on. In all patients, preoperative, perioperative, and postoperative data were recorded. Such patients were identified and included in a retrospective analysis focused on gender-related differences., Results: Patients were predominantly female ( n = 64; 80%). The mean age was 62.76 ± 13.42 years in female patients and 59.65 ± 15.84 years in male patients ( p = 0.438). The body mass index (BMI) was comparable in both groups: between 27.36 ± 6.16 in male and 27.09 ± 5.75 ( p = 0.945) in female patients. Logistic EuroSCORE (LogES) (female: 5.89 ± 4.6; male: 3.95 ± 3.06; p = 0.017) and EuroSCORE II (ES II) (female: 2.07 ± 2.1; male: 0.94 ± 0.45; p = 0.043), both scores to predict the mortality in cardiac surgery, were significantly higher in female patients. Two patients died early, within 30 days after surgery: one male and one female patient. Late mortality was defined as the 5-year survival rate, which was 94.8%, and 15-year survival rate, which was 85.3% in our cohort. Causes of death were not related to the primary tumor operation. The follow up showed that satisfaction with surgery and long-term outcome was high., Conclusion: Predominately female patients presented with left atrial tumors over a 17-year period. Relevant gender differences aside from that were not evident. Surgery could be performed with excellent early (within 30 days after surgery) and late results (follow up after discharge).

Objective : Cardiosurgical mitral valve repair (MVR) cannot be easily replaced by other interventional procedures due to the complexity of mitral valve regurgitation as well as physiologic and anatomic repair techniques. A wide variety of techniques have been adopted for proper reconstruction of posterior leaflet prolapse. We investigated the long-term results of quadrangular resections and compared them with a simplified reconstruction maneuver, the inverse plication. Methods : We retrospectively collected data from 1977 patients after mitral valve repair between 2004 and 2022. After considering inclusion and exclusion criteria, we analyzed data from 180 patients after MVR with and without concomitant procedures such as CABG and/or aortic valve replacement (AVR). All MVRs were performed with a semi-rigid annuloplasty ring. A total of 180 patients received quadrangular resection (QuadRes, N = 120)) or inverse plication (InvPlic, N = 60) of the posterior leaflet, among other measures. Demographic data, risk factors, procedure times, hospitalization time, early and long-term mortality as well as Kaplan-Meier survival were analyzed. Results : Age (65.3 vs. 63.1 years) and sex (28.8% female vs. 337.5% female) did not differ significantly, and the EuroSCORE was significantly higher in the InvPlic group (6.46 ± 2.75) than in the QuadRes group (5.68 ± 3.1). Procedural times did not differ for cardiopulmonary bypass, and were as follows: InvPlic 136 ± 44 min; QuadRes 140 ± 48 min; X-Clamp: InvPlic 91 ± 31 min; QuadRes 90 ± 32 min. Hospitalization time was slightly but insignificantly lower in the InvPlic group (15.5 days) than in the QuadRes group (16.1 days). Early mortality (5.08% vs. 8.33%) and re-do procedures (1.69% InvPlic; 6.67% QuadRes) did not differ significantly. However, long-term mortality was significantly lower in the InvPlic group (15.25% vs. 32.32%, p = 0.029). Conclusions : Among the surgical measures for the posterior leaflet, inverse plication appears to be non-inferior to quadrangular resection in unselected all-comer patients. Long-term results and absence of re-do procedures indicate very good stability. Thus, inverse plication not only allows correction of PML, but is also completely safe in the long term and can replace quadrangular resection, especially in patients where a reduction in technical challenges and procedure duration is desired., Competing Interests: The authors declare no conflicts of interest.

Background: Demographic changes have led to an increase in the proportion of older patients undergoing heart surgery. The number of endocarditis cases is also steadily increasing. Given the sharp increase in patients who have received valve prostheses or electrophysiological implants, who are on chronic dialysis or taking immunosuppressants, the interdependence of these two developments is quite obvious. We have studied the situation of older patients suffering from endocarditis compared to younger ones. Are they more susceptible, and are there differences in outcomes? Patients and Methods: A total of 162 patients was studied from our database, enrolled from 2020 to 2022. Fifty-four of them were older than 75 years of age (mean age 79.9 ± 3.8 years). The remaining 108 patients had a mean age of 61.6 ± 10.1 years. EuroSCORE II (ES II) was higher in the older patients (19.3 ± 19.7) than in the younger ones (13.2 ± 16.84). The BMI was almost identical. The preoperative NYHA proportions did not differ. A statistical analysis was performed using R. Results: Older patients had a lower left ventricular ejection fraction (LVEF), a higher proportion of coronary heart disease (CHD), a higher amount of N-terminal probrain natriuretic peptides (NT-proBNPs), worse coagulation function, worse renal function than younger patients, and were more often valve prosthesis carriers compared to the younger patients. The diagnostic interval was 66.85 ± 49.53 days in the younger cohort, whereas it was only 50.98 ± 30.55 in the elderly ( p = 0.081). Significantly fewer septic emboli were observed in the older patients than in the younger patients, but postoperative delirium and critical illness polyneuropathy and critical illness myopathy (CIP/CIM) were observed significantly more frequently compared to younger patients. In-hospital mortality was higher in older patients than in younger patients, but did not reach statistical significance (29.91% vs. 40.38%; p = 0.256). The postoperative clinical status was worse in older patients than in the younger ones (NYHA-stage, p = 0.022). Conclusions: Age did have an impact on the outcome, probably due to causing a higher number of cumulative preoperative risk factors. However, an interesting phenomenon was that older patients had fewer septic emboli than younger patients. It can only be speculated whether this was due to a shorter diagnostic interval or lower mobility, i.e., physical exertion. Older patients suffered more frequently than younger ones from typical age-related postoperative complications, such as delirium and CIP/CIM. In-hospital mortality was high, but not significantly higher compared to the younger patients. Considering the acceptable mortality risks, and in light of the lack of alternatives, older patients should not be denied surgery. However, individual consideration is necessary.

Background: Endocarditis is continuously increasing. Evidence exist that the prognosis is adversely affected by the extent of the disease. We looked at risk factors influencing in-hospital mortality (HM)., Patients and Methods: Between 2010 and 2019, 484 patients, 338 males (69.8%) with mean age of 66.1 years were operated on because of proven endocarditis. In a retrospective study, a risk factor analysis was performed., Results: Overall HM was 30.17%. Significant influencing factors (odds ratios [ORs] or p -value) for HM were: age ( p  = 0.004), logistic EuroSCORE ( p < 0.001), gender (OR = 1.64), dialysis (OR = 2.64), hepatic insufficiency (OR = 2.17), reoperation (OR = 1.77), previously implanted valve (OR = 1.97), periannular abscess (OR = 9.26), sepsis on admission (OR = 12.88), and number of involved valves (OR = 1.96). Development of a sepsis and HM was significantly lower if Streptococcus mitis was the main pathogen in contrast to other bacteria ( p < 0.001). Staphylococcus aureus was significantly more often found in patients with a previously implanted prosthesis ( p  = 0.03) and in recurrent endocarditis ( p  = 0.02), while it significantly more often showed peripheral septic emboli than the other pathogens ( p < 0.001)., Conclusion: Endocarditis remains life-threatening. Severe comorbidities adversely affected early outcome, particularly, in presence of periannular abscesses. Patients with suspected endocarditis should be admitted to a specialized heart center as early as possible. Streptococcus mitis appears to be less virulent than S. aureus . Further studies are required to verify these findings., Competing Interests: None declared., (Thieme. All rights reserved.)

Background: Atherosclerosis, hypertension, age, and fibrillopathies are well-known risk factors for the development of aortic aneurysm. We discovered that a significant proportion of our patients were previously on chemotherapy treatment or long-term treatment with cytostatic agents or immunosuppressive drugs. Thus, we examined this phenomenon., Methods: A total of 224 patients with thoracic aorta aneurysm were retrospectively analyzed after aortic surgery from 2006 to 2016. Seventy-three patients received aortic wrapping and 151 patients underwent aortic replacement of which 89 had a valve-carrying conduit and 62 a supracoronary ascending replacement. Aortic morphology was assessed by means of compute tomography scan before and after surgery. Demographic data, risk profile, and postoperative complications were collected. Short- and long-term survival analysis was performed. Statistical analysis was performed with SPSS 19.0., Results: Eighty-eight of 224 patients undergoing aortic surgery because of aortic aneurysm had previously or currently been treated with immunosuppressive agents. Dilatation of the ascending aorta was more pronounced in patients without such therapy. Demographic profile, intraoperative, as well as short- and long-term postoperative results did not differ significantly between both groups., Conclusion: The potential effect of immunosuppressant and cytostatic therapies on the development of an aortic aneurysm needs further study. Because of the astoundingly high proportion of these patients being found in an unselected aortic aneurysm cohort with immunosuppressive therapy in the past should be monitored for potential development of aortic aneurysm. If it occurs and requires treatment these patients can fortunately be operated upon with the same short- and long-term outcome than patients without such previous therapy., Competing Interests: Disclosure The authors report no conflicts of interest in this work., (Thieme.

Objective: Age has an undeniable impact on perioperative mortality. However, it is not necessarily a predictor of frailty per se, as older patients have different outcomes. To verify specific conditions underlying frailty, we examined demographics, comorbidities, frequency, and distribution of postoperative complications influencing outcomes in a challenging cohort of patients undergoing mitral valve surgery. Methods: The study enrolled 1627 patients who underwent mitral valve surgery. Patients younger than 40 years who had been diagnosed with endocarditis were excluded. Patients were divided into three groups with ages ranging from 40−59 (n = 319), 60−74 (n = 795), and >75 years (n = 513). Baseline, comorbidities, postoperative complications, and mortality were recorded. Results: The older the patients were, the more frequently they suffered from pre- and postoperative renal insufficiency (p < 0.001). The likelihood of postoperative renal failure requiring dialysis was significantly higher with pre-existing renal failure. There was a significant association between postoperative renal insufficiency and the development of postoperative pleural or pericardial effusion (p < 0.001, p = 0.016). A significant decrease in BMI was observed in patients >75 years of age compared to the 60−74 years group (27.3 vs. 28.2 kg/m2, p = 0.007). The development of critical illnesses such as myopathy and neuropathy (CIP/CIM) was age-dependent and increased significantly with age (p = 0.04). Hospitalization duration and mortality also increased significantly with age (p = 0.013, p < 0.001). Conclusions: It appears that elderly patients with advanced renal failure have a significantly higher risk of mortality, postoperative renal failure, need for dialysis, and possibly the development of pleural and pericardial effusions in mitral valve surgery. In addition, more frequent CIP/CIM with concomitant decrease in BMI in the most advanced age group indicate sarcopenia and thus an additional feature of frailty besides renal failure.

Background and Objectives: Developing a prosthetic heart valve that combines the advantageous hemodynamic properties of its biological counterpart with the longevity of mechanical prostheses has been a major challenge for heart valve development. Anatomically inspired artificial polymeric heart valves have the potential to combine these beneficial properties, and innovations in 3D printing have given us the opportunity to rapidly test silicone prototypes of new designs to further the understanding of biophysical properties of artificial heart valves. TRISKELION is a promising prototype that we have developed, tested, and further improved in our institution. Materials and Methods: STL files of our prototypes were designed with FreeCad 0.19.2 and 3D printed with an Agilista 3200W (Keyence, Osaka, Japan) using silicones of Shore hardness 35 or 65. Depending on the valve type, the support structures were printed in AR-M2 plastics. The prototypes were then tested using a hemodynamic pulse duplicator (HKP 2.0) simulating an aortic valve cycle at 70 bpm with 70 mL stroke volume (cardiac output 4.9 L/min). Valve opening cycles were visualized with a high-speed camera (Phantom Miro C320). The resulting values led to further improvements of the prototype (TRISKELION) and were compared to a standard bioprosthesis (Edwards Perimount 23 mm) and a mechanical valve (Bileaflet valve, St. Jude Medical). Results : We improved the silicone prototype with currently used biological and mechanical valves measured in our setup as benchmarks. The regurgitation fractions were 22.26% ± 4.34% (TRISKELION) compared to 8.55% ± 0.22% (biological) and 13.23% ± 0.79% (mechanical). The mean systolic pressure gradient was 9.93 ± 3.22 mmHg (TRISKELION), 8.18 ± 0.65 mmHg (biological), and 10.15 ± 0.16 mmHg (mechanical). The cardiac output per minute was at 3.80 ± 0.21 L/min (TRISKELION), 4.46 ± 0.01 L/min (biological), and 4.21 ± 0.05 L/min (mechanical). Conclusions: The development of a heart valve with a central structure proves to be a promising concept. It offers another principle to address the problem of longevity in currently used heart valves. Using 3D printing to develop new prototypes provides a fast, effective, and accurate way to deepen understanding of its physical properties and requirements. This opens the door for translating and combining results into modern prototypes using highly biocompatible polymers, internal structures, and advanced valve layouts.
