Pseudoaneurysm of the ascending aorta following cardiac surgery is very unusual and it is poten- tially fatal. We report here a fourteen year-old female patient with pseudoaneurysm of the ascending aorta following a repair of a congenital ventricular septal defect at other hospital 50 months ago. Although she had a mild superficial wound infection postoperatively, she enjoyed uneventful. life until she visited our hospital for a generalized weakness and exertional dyspnea which developed a month ago. Chest CT and echocardiogram showed partially calcified pseudoaneurysm of the ascending aorta. Two aortic defects were located on the anterolateral ascending aortic wall wkere it was suspected as a previous sites of aortic and cardioplegic cannulation. The internal wall of the pseudoaneurysm was covered with neoendothelium and intervened by septal tissue. Two defects on he aortic wall were oval in shape and about 1.5cm in the greatest diameter The defects were trimmed to make a one large de- fect and it was reconstructed with patch designed from 22mm collagen impregnated double velour Dacron graft. The postoperative course was uneventful.

Under median sternotomy and left thoracotomy, extra-anatomic aorta bypass between ascending aorta and descending thoracic aorta without cardiopulmonary bypass support has been done effectively and easily without complications for a selected case of atypical coarctation associated with hypoplasia of aortic arch. It should be considered as an alternative operative technique for complex aortic arch reconstruction.

Stanford type A aortic dissection after graft replacement of ascending aorta and/or aortic arch required careful follow-up due to progression of the enlarged false lumen or the recurrence of dissection. From June 1984 to June 200, 124 patients underwent operations for type A aortic dissection. Among them, 6 patients underwent reoperation due to recurred aneurysm or dissection. We evaluated that the causes of reoperation, including Marfan syndrome, the approach and result of reoperation, and strategy to reduce the risk of reoperation. Material and method: The first operation was done on acute stage in 4 cases, and chronic stage in 2 cases. There were Marfan syndromes in 3 cases. The entry site was the ascending aorta for all cases except one who underwent Bentall operation(n=3) or ascending aorta graft replacement(n=2). In one case, Bentall operation and total arch replacement was performed due to chronic type A dissection with multiple fenestrations. Mean interval of reoperation was 67.6months(range 5 months to 14 year 4months) after the first operation. Reoperations were performed with recurrence of dissection(n=4), threatening aneurysmal evolution of persisting dissection(n=1), and false aneurysm with infection(n=1). The redo operation involved the hemiarch in 1 case, distal ascending to total arch and descending thoracic aorta in 4 cases, and only descending thoracic aorta in 1 case. Result: There were Marfan syndromes in 18 patients. The mean age in type A dissection was 56.7 years and that in the first operation of reoperationc ases was 32.2 years. Especially in 3 patients with Marfan syndrome, the mean age was 29 years.

Reduction aortoplasty has been advocated for dilatation of the ascending aorta associated with aortic valve disease in older, high-risk patients. We report our results with modification of reduction aortoplasty and aortic valve replacement. Material and Method: Between July 2001 and December 2002, 14 consecutive patients who underwent modification of reduction aortoplasty, suture plication technique without excision of the dilated aortic wall, were reviewed. The mean age was 63.7$\pm$6.7 (50 to 75) years. Ten patients had congenital bicuspid aortic valve, Twelve patients had severe aortic valve stenosis and 6 had regurgitation of grade III$\~$IV. The diameter of the ascending aorta was measured before and immediately after surgery and 6 and 12 months postoperatively using echocardiography or computed tomography. Follow-up was complete in an average of 14.7$\~$5.4 (7 to 24) months. Result: There were no early postoperative deaths and no bleeding complications. Reduction aortoplasty with suture plication technique decreased the diameter of ascending aorta from 49.4$\pm$3.5 mm preoperatively to 33.2$\pm$3.4 mm postoperatively (p <0.001). During follow-up, there were no late deaths and no aneurysm recurrence on the ascending aorta. Conclusion: Suture plication technique of reduction aortoplasty without excision of the dilated aortic wall offers good early and short-term results in older, high-risk patients with dilatation of the ascending aorta associated with aortic valve disease. Surgical long-term results of our technique should be evaluated in further studies.

A case of Annuloaortic Ectasia associated with Marfan syndrome and mitral regurgitation is treated surgically by Bentall`s method and mitral annuloplasty. The Annuloaortic Ectasia is frequently accompanied with Marfan syndrome, its definition is simply explained as the following; the marked dilatation of the sinuses of Valsalva and the aortic annulus as well as the huge aneurysm of the ascending aorta. As the operative finding, the intimal tearing was shown as circular and the both coronary ostia were changed the position into high up. The patient was taken a corrective operation replacing the ascending aorta and aortic valve with a composite graft[St. Jude medical valve 29mm, woven Dacron tubular graft 31mm]. The both coronary ostia were reimplanted on the graft with 4-0 prolene by continuous suture. Mitral annuloplasty was performed. After the operation, the patient developed both spontaneous pneumothorax, he improved state by the closed thoracostomy. He has been doing well, postoperatively.

Over the past 6 years, from July, 1981. through June, 1987., 14 consecutive patient with congenital aortic stenosis underwent corrective surgery in our department of Thoracic and Cardiovascular Surgery. The patient ranged in age from 1 to 20 years. There were 8 male and 6 female patients. According to the operative findings, stenotic site was valvular stenosis [5 cases], subvalvular stenosis [5 cases], supravalvular stenosis [2 cases], valvular and supra valvular stenosis [1 case]. We have performed valvotomy and commissurotomy [5 cases]. Resection of subvalvular membrane [3 cases], patch enlargement of Ascending aorta [2 cases], LV myotomy [2 cases], valvotomy and excision of membrane [1 case], patch enlargement of ascending aorta and valve ring [1 case]. There was one hospital mortality [7.1%]. He died of C-I bleeding and sepsis on the 25th postoperative day. All survivors showed improvement in NYHA functional class in the 160 patient/month follow up period.

Left ventricular free wall rupture following acute myocardial infarction (AMI) is the second most common cause of death and has been reported to be responsible for 4 to 24% of all infarction deaths. The rupture occurs anywhere from a few hours to several days after AMI. The common findings of ventricular rupture are persistent chest pain bradycardia and shock. This may be often mistaken for the ruptured dissection of the ascending aorta. The different points from dissection are 1) persistent chest pain 2)persistent ST segment elevation and 3) only intramural hematoma in ascending aorta. We have sucessfully managed two patients with postinfarction myocardial rupture. Surgical management consisted of infarctectomy repairi of the ventricular rupture and coronay artery bypass grafting. We conclude that successful surgical management of ventricular free wall rupture should require prompt diagnosis and emergency operation.

This is a report of successful management of a patient with complicated native valvular endocarditis. Initially stable patient showed sudden collapse at the end of 4th week of antibiotics coverage. Echocardiography revealed that previous vegetation at the Aorto-mitral Fibrous Skeleton[AMFS developed into a false aneurysm, perforated to left atrium and caused fistulous communication between left ventricle and left atrium. Extensive debridement was performed including part of the ascending aorta, aortic cusps, the AMFS, anterior mitral cusp and roof of the left atrium. Reconstruction of the AMFS with tailored single piece of autologous pericardium enabled the implantation of mechanical valves at the aortic and the mitral position. Ascending aorta and roof of the left atrium were repaired with autologous pulmonary artery patch graft and another autologous pericardial patch. The patient was discharged on postoperative 16th day and followed - up till now without any residuae or sequelae.
