title: [Myocardial perfusion in mitral valve prolapse with arrhythmic syndrome].
abstract: Myocardial perfusion was studied in 12 patients with mitral valve prolapse concurrent with cardiac arrhythmias by using two-dimensional 201Tl myocardial scintigraphy at rest and during exercise test. Signs of myocardial ischemia were revealed only in one case. Five patients were found to have steady-state perfusion defects whose extent correlated with the depth of mitral valve prolapse. There was an irregular distribution of myocardial blood flow, which ceased on exercise in 10 out of 12 patients. Patients with ventricular premature contraction displayed a decreased reserve of myocardial blood flow as compared to those with supraventricular premature contraction, presumably by enhancing myocardial perfusion at rest.
