title: Aortic valve tumor: an unusual cause of coronary obstruction during cardiac catheterization.
abstract: Coronary artery obstruction during cardiac catheterization is a rare but serious complication that has been reported to occur in 0.15 to 0.5% of cases. The most common causes of intraprocedural coronary occlusion include thromboembolism, air embolism, and coronary dissection. This report describes the angiographic findings of a patient who developed chest pain with electrocardiographic evidence of myocardial ischemia due to obstruction of the right coronary artery by an aortic valve tumor.
