Abstract
This case report describes an iatrogenic right coronary artery–to-right ventricle fistula resulting from percutaneous transluminal coronary angioplasty. In this patient transthoracic echocardiography with Doppler color flow mapping allowed direct visualization of the right coronary artery aneurysm and the coronary fistula, enabling us to identify the cardiac chamber into which the fistula drained. Transthoracic echocardiography was used for follow-up of this patient, demonstrating spontaneous closure of the fistula within 3 months of the procedure. In addition, this article provides a brief overview of reported cases of percutaneous transluminal coronary angioplasty–induced coronary fistulae. The clinical course of this complication and therapeutic approaches presented in the literature are also briefly discussed.
