Surgical repair for left coronary artery-right atrium fistula with giant coronary aneurysm

Abstract

Abstract Background Coronary artery fistula is a rare coronary anomaly which is defined as a communication between coronary artery and other heart chambers or vascular structures. The coronary artery which supply the fistula with blood can dilated, as a consequence, coronary aneurysm developed. Case introduction Coronary artery fistula is frequently asymptomatic in its early stage, here we report a 26-year-old woman with left coronary artery fistula and left coronary artery aneurysm who presented in our hospital with dyspnea, fatigue and palpitation. The orifice of fistula was closed by continuous suture via right atriotomy. The wall of the aneurysm and enlarged LCA were partially resected along its longitudinal axis so that we can reduce the diameter of LCA to approximately normal. Conclusion This technique provides a safe method for surgical repair of the giant coronary artery aneurysm with CAF.
