Mitral valve prolapse and cerebral ischemic events in young patients.
We evaluated 32 young patients with mitral valve prolapse (MVP) as the only recognized cause of cerebral ischemia. The mean follow-up from the time of the first ischemic event was 8 years. At the time of the follow-up evaluation, 24 patients (75%) had a normal cardiac examination, and 4 had midsystolic clicks; only 1 had the characteristic click-murmur. In 75%, the first ischemic event was stroke. When MVP-associated ischemia was recognized, 44% had recurrent ischemic events. In the mean 4-year period between diagnosis of MVP-associated ischemia and follow-up, 16% had recurrent ischemic events, but none had a new persistent deficit from these events. At the time of follow-up, 63% of patients were taking platelet antiaggregants or anticoagulants. These data suggest a good prognosis for recurrent ischemic events after diagnosis of MVP-associated ischemia.
