Ischemic procedure with mitral valve prolapse

Abstract

Mitral valve prolapse (hereinafter referred to as PMV) has attracted increasing attention in recent years. It can cause arrhythmia, mitral valve insufficiency, bacterial endocarditis and even death. Echocardiography studies have reported a prevalence of 0.5% in males and 6% in females in "normal" youth. This paper reports 12 cases of PMV patients with recurrent transient ischemic attacks or incomplete non-progressive strokes confirmed by cardiac angiography. These cases were discovered while exploring a trial of platelet-inhibiting drugs for transient ischemic attacks (T1A for short) and incompletely non-progressive strokes. Among them, there were 7 males and 5 females, aged from 18 to 67 years old, with an average of 38 years old. The mean age of another group of T1A patients with arteriosclerosis was 62 years. The cardiac symptoms of 12 patients with PMV were mostly chest pain, palpitation, dizziness, syncope, pale complexion and so on. Physical examination included mid-systolic clicks or mid-systolic, late or full-systolic murmurs, sinus tachycardia, nodal extrasystole, and paroxysmal atrial fibrillation. One had ventricular tachycardia and died two years later. Another case had intraventricular conduction block. There are also those without symptoms and signs. Nervous system manifestations: 8 cases had multiple seizures, and 4 cases had single seizures. The intermission period is several months or several years, or shorter. Most of them are typical T1A,
