Values are means (SD); n = 18 patients with holosystolic mitral valve prolapse (MVP) and 14 patients with late systolic MVP. EF, ejection fraction; LA, left atrium; LVEDV, left ventricular end-diastolic volume; LVESV, left ventricular end-systolic volume; MV, mitral valve; PM, papillary muscle; Postop, postoperative; Preop, preoperative; VC, vena contracta.
