Whereas pharmacological therapy of heart failure has been shown to ameliorate CSA, results from previous studies on the effect of mitral regurgitation therapy on SDB are contradicting. The aim of this study was to assess the impact of transcatheter edge-to-edge mitral valve repair (TEER) on prevalence and severity of CSA.<\/jats:p>\n              <\/jats:sec><jats:sec>\n                <jats:title>Methods and results<\/jats:title>\n                <jats:p>We enrolled 47 patients undergoing TEER for symptomatic mitral regurgitation in a prospective study. Secondary mitral regurgitation and left ventricular ejection fraction\u2009&lt;\u200950% were present in 79% and 68% of patients, respectively. Respiratory polygraphy was performed before TEER in a compensated condition and four weeks after the procedure. 34 patients completed the follow-up. At baseline, 19 (56%) patients showed moderate-to-severe SDB, of whom 13 (68%) were classified as CSA. Both apnoea-hypopnoea index and percentage of recorded time spent in Cheyne-Stokes respiration strongly decreased from baseline to follow-up (median [IQR] 16 [7\u201330] vs. 7 [4\u201315] \/h, <jats:italic>p<\/jats:italic>\u2009=\u20090.007; 6 [0\u201334] vs. 0 [0\u20138] %, <jats:italic>p<\/jats:italic>\u2009=\u20090.008). Median relative reduction of central apnoea index was 75% (<jats:italic>p<\/jats:italic>\u2009=\u20090.023), while obstructive apnoea index did not change significantly.
