Suspicion of intraoperative left main coronary artery extrinsic compression with Perceval® sutureless bioprosthesis.

We present an uncommon case of intraoperative transient myocardial ischemia related to suspicion of left main stem artery extrinsic compression caused by the radial force of the stent of Perceval® bioprosthesis. No other cases have been described, but some similarities can be found with extrinsic coronary compression in percutaneous pulmonary valves. Surgeons should be aware of this complication in patients with coronary anomalies or with bicuspid anatomy.

Prognostic assessment of valvular surgery in active infective endocarditis: multicentric nationwide validation of a new score developed from a meta-analysis.

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.

Role of age and comorbidities in mortality of patients with infective endocarditis.

Purpose: The aim of this study was to analyse the characteristics of patients with IE in three groups of age and to assess the ability of age and the Charlson Comorbidity Index (CCI) to predict mortality.

Methods: Prospective cohort study of all patients with IE included in the GAMES Spanish database between 2008 and 2015.Patients were stratified into three age groups:<65 years,65 to 80 years,and ≥ 80 years.
