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

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.

Keywords: Coronary aneurysm; Coronary artery fistula; Surgical repair.

Transthoracic echocardiography showed a giant coronary aneurysm originated from distal left coronary artery and normal right coronary artery (LCA: Left coronary artery; RCA: Right coronary artery; RV: Right ventricle; RA: Right atrium)

Fig. 2
Transthoracic echocardiography revealed the LCA terminated in right atrium (arrow), proximal part of LCA was enlarged and the aneurysm (asterisk) was measured 56 × 45 mm (RV: Right ventricle; RA: Right atrium)

Multi-slice computed tomography angiography confirmed the diagnosis of LCA and revealed the significant enlargement of the LCA (arrow), the measured diameter of the coronary aneurysm (asterisk) was 45 × 56 mm and of the orifice of fistula was 9 mm (LCA: Left coronary artery; RV: Right ventricle; RA: Right atrium; AO: Aorta; PA: Pulmonary Artery)
