Strain and mitral regurgitation: is atrial functional mitral regurgitation a ventricular disease?

Contemporary Echocardiographic Evaluation of Mitral Regurgitation and Guidance for Percutaneous Mitral Valve Repair

“…Atrial MR is the result of atrial and consequent annulus dilatation in the presence of a normal left ventricle. Recently, Bursi et al [6] have pointed out that atrial functional MR might also be the result of the interplay between ventricular and atrial disfunction, showing that the differentiation between atrial and ventricular functional MR could sometimes be simplistic.…”

Heartbeat: pre-eclampsia is a cardiovascular disease risk factor

“…Bursi and Lee propose in an editorial4 that perhaps ‘atrial’ secondary MR actually is a disease of the ventricle with mitral annular dilation and dysfunction reflecting increased LV myocardial wall stress or elevated LV filling pressures. The data from Meucci and colleagues3 supports this concept given that LV strain, not LA strain, was predictive of clinical outcomes in patients with ‘atrial’ secondary MR.…”
