Correlation between left atrial volume index and pulmonary artery pressure in patients with chronic severe mitral regurgitation.

Left atrial dilatation is a response to volume overload in chronic mitral regurgitation (MR). Left atrium volume index (LAVI) was associated with mortality, heart failure and atrial fibrillation in patients with MR. The authors do not know the association between LAVI and pulmonary artery pressure in patients with chronic severe primary MR.The authors retrospectively studied patients with chronic severe MR (either one or both echocardiographic...
