Prevalence of sleep-disordered breathing in patients with mitral regurgitation and the effect of mitral valve repair.

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
purposeThe relationship between chronic heart failure and sleep-disordered breathing (SDB) has been frequently described. However, little is known about the association of mitral regurgitation (MR) and SDB or the impact of transcatheter mitral valve repair (TMVR) on SDB. Our aims were first to determine the prevalence of SDB in patients with MR, and second to determine the effect of TMVR on SDB.
methodsPatients with MR being evaluated for TMVR at the University Hospital Bonn underwent polygraphy (PG) to determine the prevalence of SDB. After TMVR, a subset of patients was followed up with transthoracic echocardiography (TTE) and PG to evaluate the effect of TMVR on SDB.
resultsIn 53 patients, mean age was 76.0 ± 8.5 years and 62% were male. Patients predominantly had more than moderate mitral regurgitation (94%). SDB was highly prevalent (68%) with predominantly central sleep apnoea (CSA, 67%). After TMVR in 15 patients, the apnoea/hypopnoea index (AHI) and central apnoea index (AI) were significantly reduced among patients with SDB (AHI - 8.0/h, p = 0.021; central AI - 6.9/h, p = 0.046). The left atrial volume index (LAVI) at baseline was significantly higher in patients with CSA than in patients with obstructive sleep apnoea (OSA) and was significantly reduced after TMVR (63.5 ml/m
conclusionSDB, especially CSA, is highly prevalent in patients with mitral regurgitation. In the follow-up cohort TMVR led to a significant reduction of the AHI, predominantly of central events. The findings of the study suggest that TMVR may be a suitable therapy not only for MR but also for the accompanying CSA. LAVI may be a useful indicator for CSA in patients with MR.
