ABSTRACT
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.
ABSTRACT
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).
ABSTRACT
OBJECTIVES: Liver cirrhosis increases the risk of death in patients having cardiac surgery, and the risk is markedly dependent on the actual stage. The EuroSCORE II, however, does not specifically address the risk of death of patients with liver cirrhosis. We investigated the predictive power of EuroSCORE II in patients with liver cirrhosis. METHODS: Between 2000 and 2020, a total of 218 patients with liver cirrhosis underwent cardiac surgery. To improve the predictive value of the EuroSCORE II, we calculated additional ß-coefficients to include liver cirrhosis in the EuroSCORE IIb. The control group included 5,764 patients without liver cirrhosis from the same period. RESULTS: Of the 5,764 patients without cirrhosis, 8.9% died early. Of those with cirrhosis, 8.9% of 146 patients with Child A stage, 52.9% of 51 patients with Child B stage and 100% of 21 patients with Child C stage died. Moreover, the EuroSCORE II showed a poor predictive value for patients in Child B and C stages. The resulting values of calculated ß using the area under the curve of the receiver operating characteristic and bootstrapping for Child stages as predictors of mortality were as follows: ßA = 0.1640205, ßB= 2.9911625 and ßC= 6.2501248. By calculating the updated EuroSCORE IIb and regenerating the receiver operating characteristic curves, we were able to demonstrate an improvement in area under the curve values. Postoperative complications, need for extracorporeal membrane oxygenation or intra-aortic balloon pump implants, intensive care unit stays and hospital stays were significantly higher in cirrhotic patients with cirrhosis compared with patients without cirrhosis. The most common cause of liver cirrhosis was alcohol abuse (55.5%). CONCLUSIONS: Although patients with liver cirrhosis represent only a small proportion of cardiac surgical cases, the poor outcomes are particularly relevant in patients with advanced stages of the disease. Our study results show that Child class A patients show outcomes similar to those of patients without liver disease whereas Child class C patients appear to be nearly inoperable, i.e. can only be operated on with exceptional risks. Including these patients in the EuroSCORE II calculation would thus represent an improvement in preoperative mortality risk assessment.
