Clinical and prognostic implications of left ventricular dilatation in heart failure.

Aims: To assess the agreement between left ventricular end-diastolic diameter index (LVEDDi) and volume index (LVEDVi) to define LV dilatation and to investigate the respective prognostic implications in patients with heart failure (HF).

Methods And Results: Patients with HF symptoms and LV ejection fraction (LVEF) < 50% undergoing cardiac magnetic resonance were evaluated retrospectively. LV dilatation was defined as LVEDDi or LVEDVi above the upper normal limit according to published reference values.

Timing of cardiac magnetic resonance and diagnostic yield in patients with myocardial infarction with nonobstructive coronary arteries.

Introduction And Objectives: The present study sought to establish the diagnostic yield of cardiovascular magnetic resonance (CMR) in a large cohort of patients admitted with myocardial infarction (MI) with nonobstructive coronary artery disease (MINOCA) based on the timing of referral to CMR.

Methods: Consecutive patients referred to CMR from January 2009 to February 2022 with a working diagnosis of MINOCA were retrospectively evaluated. Cine, T-weighted, early, and late gadolinium-enhanced images were acquired and analyzed.

Left-to-right ventricular volume ratio and outcome in heart failure with preserved ejection fraction.

Background: Age-specific and gender-specific reference values for left ventricular (LV) and right ventricle volumes are available. The prognostic implications of the ratio between these volumes in heart failure and preserved ejection fraction (HFpEF) have never been evaluated.

Methods: We examined all HFpEF outpatients undergoing a cardiac magnetic resonance from 2011 to 2021.

Spanish Registry of Acute Aortic Syndrome (RESA). Changes in therapeutic management and lower mortality in acute aortic syndrome.

Introduction And Objectives: The Spanish Registry of Acute Aortic Syndrome (RESA) was launched in 2005 to identify the characteristics of acute aortic syndrome (AAS) in Spain. The aim of this study was to analyze the differences in management and mortality in the 3 RESA iterations.

Methods: We analyzed data from patients with AAS prospectively included by 24 to 30 tertiary centers during the 3 iterations of the registry: RESA I (2005-2006), RESA-II (2012-2013), and RESA III (2018-2019).

Prevalence and factors associated with atrial mitral and tricuspid regurgitation in patients with atrial fibrillation.

Background: This study aimed to examine the prevalence of atrial tricuspid regurgitation (ATR) and atrial mitral regurgitation (AMR) in the setting of atrial fibrillation (AFib) and identify variables related to the severity of both types of regurgitation.

Methods: Cross-sectional study evaluating data from transthoracic echocardiograms performed during 2019. We included patients with AFib during the examination, and without primary valve disease or other significant heart disease.
