Cardiovascular magnetic resonance in patients with mitral valve prolapse.

With a prevalence of 2-3% in the general population, mitral valve prolapse (MVP) is the most common valvular heart disease. The clinical course is benign in the majority of patients, although severe mitral regurgitation, heart failure, and sudden cardiac death affect a non-negligible subset of patients. Imaging of MVP was confined to echocardiography until a few years ago when it became apparent that cardiovascular magnetic resonance (CMR) could offer comparative advantages for detecting and quantifying mitral valve abnormalities alongside tissue myocardial characterization.

Qualitative American Heart Association plot of late gadolinium enhancement with mortality and ventricular arrhythmia prediction using artificial intelligence.

Background: The prognostic value of late gadolinium enhancement (LGE) in cardiac magnetic resonance (CMR) imaging is well-established. However, the direct relationship between image pixels and outcomes remains poorly understood. We hypothesised that leveraging artificial intelligence (AI) to analyse qualitative LGE images based on American Heart Association (AHA) guidelines could elucidate this relationship.

Clinical parameters of death and heart failure hospitalization in biventricular systolic dysfunction assessed via cardiac magnetic resonance.

Aims: While factors associated with adverse events are well elucidated in setting of isolated left ventricular dysfunction, clinical and imaging-based prognosticators of adverse outcomes are lacking in context of biventricular dysfunction. The purpose of this study was to establish role of clinical variables in prognosis of biventricular heart failure (HF), as assessed by cardiac magnetic resonance imaging.

Methods: Study cohort consisted of 840 patients enrolled in DERIVATE registry with coexisting CMR-derived right ventricular (RV) and left ventricular (LV) dysfunction, as defined by RV and LV ejection fractions ≤45 % and ≤ 50 %, respectively.

Fast cardiac T mapping using slice-selective adiabatic spin-lock preparation pulses.

Purpose: Myocardial T mapping techniques commonly acquire multiple images in one breathhold to calculate a single-slice T map. Recently, non-selective adiabatic pulses have been used for robust spin-lock preparation (T). The objective of this study was to develop a fast multi-slice myocardial T mapping approach.

Prognostic value of right ventricular involvement in hypertrophic cardiomyopathy: A systematic review and meta-analysis.

Background: Right ventricular (RV) involvement has been reported in one out of three patients with hypertrophic cardiomyopathy (HCM), however its prognostic significance remains unknown. We aimed to assess the prognostic value of RV involvement in patients with HCM through a systematic review and meta-analysis.

Methods: A literature search was performed on PubMed, ClinicalTrials.
