MR, mitral regurgitation; NYHA, New York Heart Association, RR, classic rigid ring; SR, physio semi-rigid ring; Preop, Preoperative; Postop, postoperative (immediate); Last f/u, last follow-up; LVEF, left ventricular ejection fraction; LVESD, left ventricular end-systolic dimension; LVEDD, left ventricular end-diastolic dimension; LAD, left atrial dimension.
All parameters were changed significantly (p < 0.001) between postoperative and last follow-up at serial examination by means of echocardiography. There were no significant differences between the 2 rings in each parameter (repeated-measures analysis of variance).
