Preclip and postclip MG and LAP were recorded. Baseline demographics, clinical, and echocardiographic outcomes, including 30\u2010day New York Heart Association (NYHA) functional status were obtained from patient charts.<\/jats:p><\/jats:sec><jats:sec><jats:title>Results<\/jats:title><jats:p>Median age was 81.5\u2009years (IQR: 76.3, 87), 34% were female and 94.5% had NYHA class III and IV functional status at baseline. At baseline, median MG was 4\u2009mmHg (IQR: 3, 5) and LAP was 19\u2009mmHg (IQR: 16, 23.5). Following MitraClip deployment, the median MG was 4\u2009mmHg (IQR: 3, 6) and the median LAP was 17\u2009mmHg (IQR: 14, 21), 69.5% of patients had less than moderate MR. There was no statistically significant association between change in MG and NYHA functional class at 30\u2009days (OR\u00a0=\u00a00.95, 95% CI: 0.76\u20131.20). However, a reduction in LAP following MitraClip deployment was significantly associated with improvement in NYHA functional status at 30\u2009days following adjustments for age and sex (aOR 3.36, 95% CI: 1.34\u20138.65).
