A Case of Right Coronary Artery Hematoma Detected by Echocardiography after Percutaneous Coronary Intervention

ABSTRACT

A 69-year-old man was admitted to undergo percutaneous coronary intervention (PCI) for chronic total occlusion of right coronary artery. He had diabetes mellitus, stable angina pectoris. Diagnostic coronary angiography demonstrated proximal total occlusion of right coronary artery. PCI was failed due to failure of balloon passage. Echocardiography was performed after PCI and thickened epicardial tissue at right atrioventricular groove was noted. It was highly echogenic and localized along the course of mid right coronary artery. In following echocardiogram after 12 days, the size of echogenic mass was decreased from 3.4 cmx2.6 cm to 1.7 cmx0.7 cm and we could conclude it was right coronary artery hematoma associated with PCI.
