Specific risk scores had better prognostic performance than classical risk scores. The STS-IE score had the highest discrimination and was adequately calibrated. The PALSUSE score also showed optimal discrimination and calibration. The De Feo-Cotrufo score had a lower discrimination in our sample; however, the De Feo-Cotrufo score is recommended in the current guidelines. The Costa score had the lowest discrimination.

IntroductionSex-dependent differences of infective endocarditis (IE) have been reported. Women suffer from IE less frequently than men and tend to present more severe manifestations. Our objective was to analyse the sex-based differences of IE in the clinical presentation, treatment, and prognosis.Material and methodsWe analysed the sex differences in the clinical presentation, modality of treatment and prognosis of IE in a national-level multicentric cohort between 2008 and 2018. All data were prospectively recorded by the GAMES cohort (Spanish Collaboration on Endocarditis).ResultsA total of 3451 patients were included, of whom 1105 were women (32.0%). Women were older than men (mean age, 68.4 vs 64.5). The most frequently affected valves were the aortic valve in men (50.6%) and mitral valve in women (48.7%). Staphylococcus aureus aetiology was more frequent in women (30.1% vs 23.1%; p<0.001).Surgery was performed in 38.3% of women and 50% of men. After propensity score (PS) matching for age and estimated surgical risk (European System for Cardiac Operative Risk Evaluation II (EuroSCORE II)), the analysis of the matched cohorts revealed that women were less likely to undergo surgery (OR 0.74; 95% CI 0.59 to 0.91; p=0.05).The observed overall in-hospital mortality was 32.8% in women and 25.7% in men (OR for the mortality of female sex 1.41; 95% CI 1.21 to 1.65; p<0.001). This statistical difference was not modified after adjusting for all possible confounders.ConclusionsFemale sex was an independent factor related to mortality after adjusting for confounders. In addition, women were less frequently referred for surgical treatment.

We report a case of a 23-year-old man who was diagnosed with Kawasaki disease that progressed to a coronary aneurysm in the left main coronary artery (LMA). He had suffered from acute coronary syndrome and then underwent an emergent percutaneous coronary angioplasty, in which a polyurethane-covered stent was placed inside the aneurysm. The stent was thrombosed one year later, despite the patient had been treated with anticoagulant and antiplatelet therapy. Emergency percutaneous intervention was then performed. LMA was reopened and stent malposition was observed. Therefore, urgent coronary bypass grafting was performed in which a high degree of competitive flow was observed through the reopened stent. LMA was ligated at the inflow of the aneurysm, resulting in an improvement of graft flow. Left main ligature has not been previously reported.

OBJECTIVES Several risk prediction models have been developed to estimate the risk of mortality after valve surgery for active infective endocarditis (IE), but few external validations have been conducted to assess their accuracy. We previously developed a systematic review and meta-analysis of the impact of IE-specific factors for the in-hospital mortality rate after IE valve surgery, whose obtained pooled estimations were the basis for the development of a new score (APORTEI). The aim of the present study was to assess its prognostic accuracy in a nationwide cohort. METHODS We analysed the prognostic utility of the APORTEI score using patient-level data from a multicentric national cohort. Patients who underwent surgery for active IE between 2008 and 2018 were included. Discrimination was evaluated using the area under the receiver operating characteristic curve, and the calibration was assessed using the calibration slope and the Hosmer–Lemeshow test. Agreement between the APORTEI and the EuroSCORE I was also analysed by Lin’s concordance correlation coefficient (CCC), the Bland–Altman agreement analysis and a scatterplot graph. RESULTS The 11 variables that comprised the APORTEI score were analysed in the sample. The APORTEI score was calculated in 1338 patients. The overall observed surgical mortality rate was 25.56%. The score demonstrated adequate discrimination (area under the receiver operating characteristic curve = 0.75; 95% confidence interval 0.72–0.77) and calibration (calibration slope = 1.03; Hosmer–Lemeshow test P = 0.389). We found a lack of agreement between the APORTEI and EuroSCORE I (concordance correlation coefficient = 0.55). CONCLUSIONS The APORTEI score, developed from a systematic review and meta-analysis, showed an adequate estimation of the risk of mortality after IE valve surgery in a nationwide cohort.
