Outcome of mitral repair combined with Cox-maze procedure for atrial functional mitral regurgitation with heart failure with recovered ejection fraction.

MV repair combined with the Cox-maze procedure was effective and feasible in patients with severe AFMR with HFrecEF. Additionally, patients with LVEF ≥ 50% after GDMT undergoing these combined procedures had better long-term freedom from recurrent AF and MR than those with LVEF of 40-50%.
