Right coronary artery distribution of myocardial bridging: an unusual case presenting with ST-Elevation myocardial infarction.
Myocardial bridging has been observed to provoke symptoms in association with strenuous physical activity and hypertrophic cardiomyopathy; more recently, bridging has been thought to cause coronary vasospasm. Autopsy findings tend to reveal higher incidences of bridging than do angiography series, but both show an almost uniform predilection for left coronary artery distribution--especially in regard to bridging that manifests itself clinically. Herein, we report an unusual case of myocardial bridging with right coronary artery distribution and important clinical implications for physicians' management of similar cases in the future.
