Impact of left atrium plication on chronic heart failure with atrial functional mitral regurgitation.

ABSTRACT:

Purpose

We hypothesized that a giant left atrium may oppress  the posterior left ventricle and aggravate diastolic dysfunction and heart failure. We evaluated the effect of left atrial plication (LAP) on atrial functional mitral regurgitation.

Methods

We retrospectively reviewed patients who underwent LAP for atrial functional mitral regurgitation at our institution between January 2017 and December 2021. Early outcomes, follow-up echocardiography data, and heart failure indicators were compared.

Results

Eighteen patients were divided into two groups: LAP + (n = 9) or LAP- (n = 9). There were no significant differences in patient characteristics and preoperative echocardiographic parameters, except for the preoperative New York Heart Association classification. Operat
