A Case of Successful Valve Repair in Traumatic Aortic Regurgitation Associated with the Dilated Aortic Annulus

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. Jpn. J.
