The right ventricle (RV) and tricuspid valve (TV) are important determinants of cardiovascular outcomes. With the rapid evolution of transcatheter tricuspid valve interventions, comprehensive multimodality imaging has become essential for patient selection, procedural guidance, and prognostic stratification. Strain and volumetric parameters enable …

Background: Tricuspid regurgitation (TR) is a common valvular heart condition associated with significantly increased mortality. It is often underdiagnosed and undertreated due to limited insight into patient-specific risk prediction and optimal timing of intervention. Machine learning (ML) methods offer the potential to …

Abstract Introduction Functional tricuspid regurgitation (TR) is a known predictor of adverse prognosis, yet risk stratification remains largely based on TR severity. Cardiac magnetic resonance (CMR) enables detailed myocardial tissue characterization and quantification of extracellular volume fraction (ECV), an increasingly recognized marker …

Abstract Background The right atrioventricular coupling index (RACI), defined as the ratio of right atrial to right ventricular end-diastolic volume, reflects the interplay between right atrial compliance and right ventricular filling pressures. However, the prognostic significance of RACI in pulmonary hypertension (PH) …
