Atrial functional mitral regurgitation (MR) in patients with chronic atrial fibrillation has not been thoroughly discussed. Although there is insufficient evidence to surgically treat atrial functional MR, it is considered to be reasonable for those patients with severe atrial functional MR who have symptoms of heart failure despite adequate medical therapy. Herein, we report a useful technique for mitral valve repair using posterior mitral leaflet (PML) augmentation with autologous pericardium to obtain good mitral valve coaptation and eliminate atrial functional MR, including tethered PML, in a nonelderly patient.
Keywords: atrial functional mitral regurgitation; mitral valve repair; pericardial patch enlargement.
