Abstract

Coronary artery anomalies are uncommon anatomical variations that are usually detected incidentally during a coronary angiogram or computed tomography angiography. We report a case of a diabetic and hypertensive middle-aged male who presented with chest discomfort. Coronary angiography revealed no signs of coronary artery disease but showed a left anterior descending artery (LAD) looping around the left ventricular apex and running through the posterior interventricular groove as a posterior descending artery (PDA) beyond the crux. The nondominant right coronary artery (RCA) and left circumflex artery (LCX) had no connection with the PDA. The patient's diabetic and hypertensive medications were adjusted, and he remained asymptomatic after 3 months. Interventionalists should be aware of the types of coronary anomalies that may complicate diagnosis and management during percutaneous coronary intervention.
