[Mitral valve prolapse syndrome].

Within one and a half year 24 patients with arrhythmias or chest pain were investigated to detect a mitral valve prolapse syndrome which was found in 9 cases by echocardiography. Within this group 6 patients complained of fatigue, dizziness, dyspnea or syncope, 6 had chest pain, 7 paroxysmal tachycardia and 2 patients premature beats. Auscultation revealed in 3 cases a systolic click, in 1 case a systolic click with late systolic murmur and in 5 cases a systolic murmur only. The ECG showed premature ventricular contractions in 2 patients, ST-T abnormalities in 6 patients. Echocardiography showed a late systolic prolapse in 6 and a pansystolic prolapse in 3 patients. In 3 cases also an angiography was performed and in this way a mitral valve prolapse detected; hemodynamics and coronary arteries were normal in all 3 cases but in one case a mitral insufficiency and in one case an asynergy of the anterior wall was found. Pathophysiology, clinical symptoms and phonocardiographic, echocardiographic and angiographic findings in mitral valve prolapse syndrome are discussed.
