Dissection of coronary arteries during diagnostic coronary angiography is infrequent; dissection of the coronary cusp is extremely rare. The combination of coronary artery and coronary cusp dissection has not been reported previously. A case of right coronary artery dissection and right coronary cusp dissection during diagnostic coronary angiography is described.
We describe a patient who survived a penetrating gunshot wound to the chest. Cardiac evaluation including echocardiography and cardiac catheterization revealed a coronary artery fistula and a ventricular septal defect. This combination has been rarely reported in patients with penetrating cardiac injury. Follow-up echocardiography performed 15 mo later showed persistent left-to-right shunt. This is the first case in the literature demonstrating the natural history of combined coronary artery fistula and ventricular septal defect without surgical correction.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
