Quantification of rheumatic mitral stenosis severity with three dimensional vena contracta area
Archives of Cardiovascular Diseases Supplements, 2020 Introduction Rheumatic mitral stenosis is a real public health problem in developing countries. Assessment of the mitral valve area (MVA) is essential for the choice of the intervention time. Most of the evaluation parameters of rheumatic MS are derived of two-dimensional echocardiography (2D).

Association between CMR‐derived hepatic T1‐time, tricuspid regurgitation and survival
European Journal of Clinical Investigation, Volume 56, Issue 1, January 2026.We investigated the association between tricuspid regurgitation (TR) severity and hepatic T1‐time in 1029 patients undergoing cardiac MRI and echocardiography. Hepatic T1‐time increased progressively with TR severity and remained independently associated after adjusting for NT‐proBNP and right ventricular function. Both TR and hepatic T1‐time predicted

Revisiting tricuspid regurgitation: Historical insights and emerging research perspectives
European Journal of Clinical Investigation, Volume 56, Issue 1, January 2026.Tricuspid regurgitation (TR), once seen as benign, is now recognized as a serious and increasingly prevalent condition linked to aging and better imaging. Its association with greater morbidity and mortality has shifted clinical perspectives towards early diagnosis and intervention.
