Background: Although the aortic valve-sparing procedure has gained popularity in recent years, it still remains challenging in patients with advanced aortic regurgitation (AR). We compared the long-term outcomes of the aortic valve-sparing procedure with the Bentall operation in patients with advanced aortic regurgitation secondary to aortic root dilatation. Materials and Methods: A retrospective review of 120 patients who underwent surgery for aortic root dilatation with moderate to severe AR between January 1999 and June 2009 was performed. Forty-eight patients underwent valve-sparing procedures (valve-sparing group), and 72 patients underwent the Bentall procedure (Bentall group). The two groups' overall survival, valve-related complications, and aortic valve function were compared. Results: The mean follow-up duration was $4.9{\pm}3.1$ years. After adjustment, the valve-sparing group had similar risks of death (hazard ratio [HR], 0.61; p=0.45), and valve related complications (HR, 1.27; p=0.66). However, a significant number of patients developed moderate to severe AR in the valve-sparing group at a mean of $4.4{\pm}2.5$ years of echocardiographic follow-up (p<0.001). Conclusion: Both the Bentall operation and aortic valve-sparing procedure showed comparable long-term clinical results in patients with advanced aortic regurgitation with aortic root dilatation. However, recurrent advanced aortic regurgitation was more frequently observed following valve-sparing procedures.

A 11 year-old girl with quadricuspid aortic avlve associated with regurgitation left superior vena cava and chromosomal anomaly is presented. The quadricuspid valve was unexpectedly found during operation for aortic valve replacement. The aortic valve consisted of 4 equal-sized cusps and retrospective review of the aortogram revealed the aortic valve to have 4 cusps also. To the best of our knowledge, this combination of anomalies has not been reported in Korea previously.

Ventricular septal defect[VSD] associated with aortic regurgitation[AR] represents 2 to 7.5% of all VSD which is most common congenital heart disease. The aortic valve may by normal in infants with VSD, but the aortic regurgitation may be developed in these patients later. The aortic valve became fibrotic, thickened, deformed and prolapsed, so these late deformities require to be corrected with plication, valvuloplasty or aortic valve replacement [AVR]. There are some controversy between the early repair of VSD alone and the late repair of VSD and aortic valve till now. From December 1971 to August 1983, we had experienced 24 patients of VSD associated with AR which constitute 6.5% of our total patients with VSD. The VSD was subpulmoary [type I] in 14[58.3%], subcristal [type II] in 8[33.3%], atrioventricular canal type[type III] in 1, and combine of type I and II in 1. Patch repair of VSD was made in 15 patients and direct suture of small VSD in 9.14 patients had aortic plication of valvuloplasty and 9 had AVR accompanying VSD repair, and 1 patient had VSD closure alone. The postoperative courses of these patients were uneventful except in some cases. A patient who was undertaken AVR with Starr-Edwards ball valve and VSD closure, died due to left ventricular failure and low cardiac output syndrome. Follow up shows, in 14 patients with aortic plication or valvuloplasty, AR was developed in 9. In 9 AVR, there were two later complications which were paravalvular leakage in one and re-AVR due to subacute bacterial endocarditis in another.

국소성 대동맥하협착은 뚜렷한 막성(discretemembraneous)에서 광범위한 터널형 협착에 이르는다 양한 병변을 보이며 드물지 않게 대동맥팥폐쇄부전이 동반된다. 이러한대동맥하협착과대동맥판폐쇄 부전은 시간이 경과함에 따라 진전되는 것으로 알려져 있으므로 조기수술이 고려되어야 한다. 븐 병 원에서는 중등도의 대동맥 판폐쇄부전이 동반된 국소성 대동맥하협착 환자 1례를 치헙하여 좋은 결과를 얻었다. 수술은 대동맥 판륜 하부의 섬유근성조직 (fibromuscular tissue)을 절제하고 비후된 심실중격에 근절제 및 근절개를 병 행 하였으며, 대동맥 판성 형술 및 교련하부판륜성 형술로 대동맥 판폐 쇄부전을 교정하였 다. 퇴 원 당시의 심장초음파검사에서 좌심실-대동맥간 수축기 압력 차이가 술전에 비 해 현저히 감소하였고 대동맥판폐쇄부전의 소견은 보이지 않았다.

A 32-year-old woman diagnosed with Turner syndrome presented to the hospital for an evaluation of cardiovascular complications. Preoperative computed tomography (CT) and echocardiography showed progression of aortic root and ascending aorta dilatation, as well as a bicuspid aortic valve. There was no evidence of aortic regurgitation. We planned valve-sparing aortic root replacement and ascending aorta replacement with a high risk of aortic rupture. Intraoperatively, we incidentally found a juxtacommissural origin of the right coronary artery (RCA). We performed aortic valve reimplantation using a graft designed with a key-shaped hole to wrap the juxtacommissural-origin RCA by modifying the Florida sleeve technique. Coronary blood flow was patent on postoperative CT angiography, and there was no evidence of aortic regurgitation on postoperative echocardiography. The patient was discharged from the hospital on postoperative day 7 without any complications.

Discrete membranous subaortic stenosis[DMSS] is one of the subtype of congenital left ventricular outflow obstruction and can be associated with aortic regurgitation, infective endocarditis, ventricular obstruction. DMSS should be removed early, when diagnosed, and completely before secondary myocardial changes occur. Recently we experienced a case of DMSS with aortic regurgitation, and its left ventricular outflow tract obstruction[LVOTO] peak systolic gradient was 10lmmHg. Resection of membrane and aortic valve replacement is adequet for LVOTO and postoperative pressure gradient was 26mmHg. Postoperative echocardiogram shows no obstuctive membrane and well functioning aortic valve.

We report the case of a patient with mitral regurgitation complicated by type B dissection and Marfan syndrome (MFS) who was managed successfully with minimally invasive mitral valve repair. Without type A aortic dissection or aortic root dilation, MFS patients may develop mitral valve regurgitation, as in this case, and need valve surgery to improve their symptoms and long-term survival. However, it is not clear that a full sternotomy and prophylactic aortic surgery are necessary. Although retrograde perfusion to the dissected aorta is controversial, our approach minimizes the risk of future anticipated aortic surgery in MFS patients.

We have experienced one case of ascending aorta aneurysm with aortic regurgitation due to atherosclerosis. The 45 year old man had been suffered from palpitation and precordial chest pain. 2-D echocardiogram and aortogram confirmed aneurysm of ascending aorta with aortic regurgitation. Atherosclerotic change was noted in the aortic wall and there was marked dilatation of the sinuses of Valsalva as well as the aortic annulus with upward displacement of coronary ostia in the operative field. The patient underwent complete replacement of the aneurysmal ascending aorta and the aortic valve with 27mm Bjork-Shiley aortic valve composite graft. We got preclotting with heparin free blood including thrombin and then autoclave at 132` for 3 minutes. The postoperative course was uneventful and the patient was discharged with good clinical result.

We have experienced two cases of ascending aorta aneurysm with aortic regurgitation in Marfan`s syndrome. There were abnormal findings in cardiovascular system associated with abnormalities of skeletal systems. They had total replacement of the ascending aorta and aortic valve with Bjork-Shiley`s aortic valve composite graft and reimplantation of coronary ostia on the graft. Their postoperative courses were uneventful and discharged with good clinical results for follow up.
