Initial experience of mitral valve replacement with total preservation of both valve leaflets.
We compared a series of 7 consecutive patients who underwent mitral valve replacement with preservation of both leaflets to a control group of 97 patients who underwent standard mitral valve replacement at our institution during the same period. Use of inotropic drugs and duration of postoperative intensive care were compared and shown to be markedly reduced in the study group; however, statistical analysis was not applied due to the small number of patients. Comparison of the available pre- and postoperative echocardiographic values showed a decrease in left ventricular end-diastolic and end-systolic diameters in patients with preserved leaflets, particularly in those with mitral regurgitation of degenerative origin.
