Project description:A 68-year-old male with a history of hypertension and hypercholesterolemia presented with recurrent episodes of chest discomfort. A 12-lead ECG and an echocardiogram were normal. A myocardial perfusion study could not rule out ischemia in the inferior wall. At coronary angiography using the transradial approach, the right coronary artery (RCA) could not be visualized. Angiography of the left coronary system demonstrated non-obstructive atherosclerosis involving the mid segment of the left anterior descending (LAD) artery and a normal circumflex (Cx) artery. The RCA originated from the mid LAD segment distal to the first septal perforator and the first diagonal branch and was free of atherosclerosis disease. A contrast-enhanced 64-slice multi-detector cardiac computed tomography showed that the LAD was severely calcified in the proximal part, and the RCA coursed anterior to the right ventricular outflow tract (RVOT) to reach the right atrioventricular groove. The patient was managed medically and became asymptomatic.

Transseptal course of anomalous left main coronary artery originating from single right coronary orifice presenting as unstable angina.

Project description:Transseptal course of coronary artery has often been described as a benign entity; however, this report and literature analysis provides growing evidence of high risk of serious cardiovascular events in this anomaly. We present a case of unstable angina in a patient with anomalous common origin of left and right coronary arteries from a single coronary ostium at the right sinus of Valsalva, with subsequent transseptal course of the left main artery, review of relevant literature, and discussion of possible management options.

Closing a Right Coronary Artery Fistula Draining Into the Coronary Sinus Using a Covered Stent in the Coronary Sinus.

Project description:This report describes the case of a symptomatic patient with a right coronary artery fistula draining into the coronary sinus who underwent transcatheter closure, which was deployed in the drainage site to seal off the exit of the fistula. (Level of Difficulty: Advanced.).
