The European Society of Cardiology quality indicators in atrial fibrillation in centers of excellence in Spain: the SEC-EXCELENTE FA registry.

Introduction And Objectives: By 2022, 9 centers had been accredited by the Spanish Society of Cardiology for the atrial fibrillation (AF) process. Our objective was to evaluate the performance of these centers based on the quality indicators (QIs) proposed by the European Society of Cardiology (ESC) in 2020.

Methods: Adults with AF who were attended in the cardiology departments of participating centers during the second week of May 2019 were included in a retrospective registry (n=797, age 72±11 years, 60% male).

Increased atrial contraction contribution to left ventricular filling during early septic shock.

Purpose: To assess the atrial systolic function and the contribution of atrial contraction to left ventricular (LV) filling in septic shock patients as compared with healthy volunteers.

Methods: Twenty-seven septic patients evaluated during first 48 h of ICU admission and compared with 27 healthy volunteers. Left atrial (LA) contraction contribution to LV filling was calculated as the active emptying atrial volume/LV end-diastolic volume.

Invasive assessment of coronary microvascular dysfunction in hypertrophic cardiomyopathy: the index of microvascular resistance.

We present a review of microvascular dysfunction in hypertrophic cardiomyopathy (HCM) and an interesting case of a symptomatic familial HCM patient with inducible ischemia by single photon emission computed tomography. Coronary angiography revealed normal epicardial arteries. Pressure wire measurements of fractional flow reserve (FFR), coronary flow reserve (CFR) and index of microvascular resistance (IMR) demonstrated a significant microcirculatory dysfunction.
