[Plastic surgery of the mitral valve in mitral valve insufficiency - advantages of physiologic surgery].
Nine patients (mean age at the time of surgery 54.5 +/- 0.7 years), who had mitral valve reconstruction for mitral valve insufficiency were studied on an average of 15.0 +/- 7.5 months after the operation using technetium-99m-pertechnetate--or gold scintigraphy. The radionuclid ventriculograms were performed with the patient in RAO-position at rest and during mild exercise (50 watt). Looking at the results of the preoperatively performed heart catheterization with contrast ventriculography our datas showed a postoperative improved left ventricular function as well as a physiologic function of the mitral valve. Clinically the patients improved from class 3.6 to 1.6 (NYHA) on an average. The reconstructive mitral valve insufficiency is able to restore normal left ventricular function. The operation should be carried out on patients graded at class II (NYHA). Technetium-99m-pertechnetate scintigraphy (first pass technique) appears to be particularly suitable for evaluating left ventricular function and the function of the mitral valve after reconstructive mitral valve surgery.
