Isolated fibromuscular dysplasia of the coronary arteries with spontaneous dissection and myocardial infarction.
Fibromuscular dysplasia (FMD) is a segmental, nonatherosclerotic vascular disease of unknown etiology. Both the renal and extrarenal arterial FMD may have focally deficient or absent muscular media, and spontaneous dissection is a serious complication of this arterial wall abnormality. Although FMD may be found in virtually any small and medium-sized arteries, to our knowledge, FMD of the coronary arteries previously has not been documented convincingly in the literature. This article describes one such unusual occurrence of FMD in the coronary arteries with spontaneous dissection and myocardial infarction.
