Congenitally absent right coronary artery in adult

Abstract

Background: A 44-year-old male patient with atrial fibrillation and cardiac insufficiency (NYHA IV) presented for evaluation for heart transplantation. He was referred for cardiac CT for assessment of potential restrictive cardiomyopathy and evaluation of his right ventricle. Cardiac CT was performed utilizing a dual-source CT scanner. ECG-adapted tube current was used to reduce radiation exposure. No pericardial calcifications were noted. The right atrium and the inferior vena cava were dilated with 82 x 58 mm and 47 mm diameter, respectively. There was no evidence of coronary artery disease.
