12 名没有动脉硬化性脑血管疾病证据、没有高血压或凝血缺陷且未接受避孕治疗的患者患有复发性短暂性脑缺血发作 (TIA) 和部分非进行性中风。经心血管造影证实，所有人均患有二尖瓣脱垂。平均年龄为 38 岁，而更大范围的与动脉硬化相关的 TIA 患者的平均年龄为 62 岁。我们认为缺血事件与异常二尖瓣发出的栓子有关，伴有或不伴有相关的阵发性心律失常。
Twelve patients who had no evidence of arteriosclerotic cerebral vascular disease, lacked hypertension or coagulation defect, and had not been receiving contraceptive therapy had recurrent transient cerebral ischemic attacks (TIAs) and partial nonprogressive strokes. All had prolapsing mitral valve proved by angiocardiography. The average age was 38 years, compared with 62 years in a larger series of patients with TIA associated with arteriosclerosis. We propose that the ischemic events are related to emboli emanating from the abnormal mitral valve with or without an associated paroxysmal cardiac arrhythmia.
