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

What it found
Each row is one number read from the abstract, on the scale the paper reported it, with its interval. Left of the dashed line favours the treatment, right favours the comparator. Under each row is the sentence it came from. New to these charts? A ten-minute tutorial.
The abstract states no effect estimate the extractor could read, or names no intervention and outcome on the map, so this paper lights no cell and moves no belief. It is still indexed, cited and linked below.
The trial behind it
Trials whose registry record cites this paper, or whose number appears in the abstract. A trial that started after this paper was published is citing it as background, not reporting it.
Neither the registry nor the abstract names a trial number. If this is a trial report, that itself is worth knowing.

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. Operative (505.7 [standard deviation: 100.0] minutes vs. 382.9 [standard deviation: 58.1] minutes, P = .0055) and cardiopulmonary bypass times (335.6 [standard deviation: 50.4] minutes vs. 246.9 [standard deviation: 62.7] minutes, P = .0044) were significantly longer in the LAP + group. No in-hospital mortalities were observed in both groups. The postoperative left atrial volume was significantly reduced in the LAP + group, and mitral regurgitation was controlled at less than mild levels in both groups. At follow-up, the left ventricular end-diastolic volume was reduced significantly in the LAP + group. Brain natriuretic peptide, cardiothoracic ratio, and the New York Heart Association classification were improved in the LAP + group. Conclusions: Additional left atrial plication contributes to the control of atrial functional mitral regurgitation and heart failure at a later stage. A careful long-term follow-up is needed as re-expansion of the left atrium is possible.
