Left atrial enlargement of degenerative mitral regurgitation: A valuable marker of outcome in routine practice?

We aimed to assess whether LA-volume-index (LAVI) measured in routine clinical practice of multiple sonographers/cardiologist is associated independently with DMR survival. A cohort of all 5769 (63 ± 16 years, 47% women) consecutive patients with degenerative mitral valve disease, in whom LAVI was prospectively measured, was enrolled and their long-term survival analyzed. LAVI (43 ± 24 ml/m2) was widely distributed (< 40 mL/m2 in 3154 patients,...
