Here, we present a case of successful aortic valve repair of traumatic aortic regurgitation (AR). A man in his early twenties had a chest blunt trauma due to a bicycle accident 6 years earlier and suffered sternum fracture. He recovered without cardiovascular complications. Three months previously, a new diastolic murmur was detected on medical checkup. Transthoracic echocardiography (TTE) showed severe AR, and the left ventricular end-diastolic-/end-systolic dimension was 69/51 mm. Transesophageal echocardiography showed severe AR with perforation of the non-coronary cusp and dilatation of the aortic annulus (29.6 mm). Aortic valve repair was performed with an autologous pericardial patch and external suture annuloplasty. Postoperative TTE showed normal aortic valve function with trivial AR. He was discharged on postoperative day 11. Three months later, TTE showed trivial AR along with a reduced left ventricular dimension and improved left ventricular ejection fraction.

A 53-year old female was noted to have an enlarged heart on a medical checkup. A multislice computed tomography study demonstrated a giant coronary artery aneurysm measuring 10 cm in diameter and a coronary arteriovenous fistula, both located below the left atrium. Resection of the aneurysm and ligation of the feeding arteries and arteriovenous fistula were performed under cardiopulmonary bypass. As the native coronary sinus was occluded, we reconstructed the vessels draining from the aneurysm into the right atrium with an autologous pericardial patch to preserve the coronary venous blood flow. To our knowledge this is the first report of an autologous pericardial patch being successfully used to reconstruct the coronary venous flow during surgical treatment of a giant coronary artery aneurysm with a coronary arteriovenous fistula.
