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.

Seventeen patients underwent operations for aneurysm of ascending aorta with aortic regurgitation from August 1979 to October 1985. 10 patients underwent complete replacement of the ascending aorta and the aortic valve with a composite graft and implantation of coronary ostia on the graft. Seven patients underwent supracoronary noncomposite graft replacement and aortic valve replacement. The patients ranged in age from 25 to 55 years [mean 37.6 years]. There were 11 male and 6 female patients. All patients had aortic incompetence and aneurysmal dilatation of the ascending aorta. Seven of the patients has concomitant aortic dissection in ascending aorta and one had dissection in abdominal aorta. Eight patients had signs of Marfan syndrome and the other 3 patients had cystic degeneration in the medial layer of the aorta. There was one hospital death[5.8%]. He died of sepsis on the 23rd postoperative day. All survivors showed improvement in NYHA functional classification in the 34.9 patient-year follow-up period.

Prosthetic valve replacement has resulted in marked improvement in the functional status of many patients with valvular heart disease. But valve failure from various causes has necessitated re-replacement of prosthetic valve in some of these patients. This selective group of patients has many inherent problems. This report presents our experience with seven patients who received re-replacement of prosthetic valve in the Seoul National University Hospital from 1981, to 1983. The patients included one woman and six men in the range of 9 and 49 years old. As the first valve operations, there were five MVR using tissue valves, one DVR [Bjork-Shiley and Ionescu-Shiley valve] and one case of modified Bentall operation with composite graft [Ionescu-Shiley valve]. Reoperations on prosthetic valve failure were performed 17 to 54 months after the first operation [mean 34 months]. Amon8 seven patients, there were two cases of prosthetic valve endocarditis and five cases of primary tissue failure. Gross calcification of the xenograft was found in two children with Ionescu-Shiley valve. All except one had relatively successful operative results. The unsuccessful one died intraoperatively from low output syndrome.

A unicuspid aortic valve is a rare congenital malformation that frequently presents with valvular dysfunction and dilatation or aortic aneurysm, requiring combined aortic valve surgery and aortic repair. Some patients show severe valve calcification extending into the interventricular septum, possibly resulting in damage to the conduction system during debridement for valve replacement. We present a rare case of severe aortic stenosis with a unicommissural unicuspid aortic valve diagnosed by preoperative transesophageal echocardiography in a 36-year-old man. After composite graft replacement of the aortic valve, aortic root, and ascending aorta, a permanent pacemaker was placed because of postoperative complete heart block.

A 64 year-old male patient with annulo-annulo-aortic ectasia[AAE] due to cystic medial necrosis was successfully treated with Cabrol operation with Cabrol trick. The technique consist of implantation of a composite valve graft within the aneurysmal sac with reattachment of the coronary ostia using a separate, small tube graft and creation of a communication between the closed perigraft space and right atrium for bleeding control. The patient had a postoperative gastrointestinal bleeding but successful recovery was achieved eventually.

From February 1985 to February 1993, 18 operations were performed in 17 patients for treatment of aneurysmal disease [n=12] and/or dissection of the ascending aorta [n=6]. The ages ranged from 26 to 69 years [mean 44.3 $\pm$ 11.0 years].The proposed operations include composite graft replacement of aortic valve and ascending aorta with coronary reimplantation in 11, graft replacement of ascending aorta alone in 5, aortic valve replacement and supracoronary graft replacement in 1 and ascending aorta to abdominal aorta bypass with thromboexclusion of descending aorta in one patient. Both Bentall [n=6] and Cabrol [n=5] technique were utilized for reimplantation of coronary arteries.Concomitant replacement of aortic arch and arch vessel reconstruction was necessary in two patients. Hypothermic circulatory arrest was utilized in 6 patients. Recently, four patients were managed on warm blood continuous cardioplegia via retrograde route. There were no operative deaths. No significant postoperative complications were noted. Postoperative follow up was complete in 15 patients from 1 month to 72 months. Redo operation was necessary in one patient who had suffered from distal recurrence of dissection 5 years after successful Bentall operation. The other patients are all in excellent clinical condition. From our early experience with those 17 cases, we assume that satisfactory operative result could be achieved with a variety of surgical technique including hypothermic circulatory arrest. In addition, continuous perfusion of warm blood cardioplegia via retrograde route is supposed to be beneficial in selected cases.

Between November, 1981 and July, 1989, 4 patients, 3 male and 1 female patients ranging in age from 36 to 45 years, were operated on for aortic insufficiency associated with uncomplicated annuloaortic ectasia. All patients were in New York Heart Association class III. Two patients had clinical stigmata of the Marfan syndrome. The surgical treatment consisted of. supracoronary replacement of ascending aorta with vascular graft and replacement of the aortic valve in our first case. and composite graft replacement of the ascending aorta and aortic valve with reimplantation of the coronary arteries in subsequent 3 cases. Our first patient developed aneurysm of proximal aorta and pseudoaneurysm of distal aortic anastomosis 5 years postoperatively. One patient among the three patients with Ben-tall operation, died of ventricular fibrillation and myocardial failure during immediate postoperative period. Remaining 2 patients were in NYHA class I with follow-up of 16 months and 20 months respectively.

Surgical repair of the tetralogy of Fallot is one of the most successful operations in the treatment of congenital heart diseases. We report the case of a 65-year-old man who had an aortic valve replacement at the time of complete repair of the tetralogy of Fallot at the age of forty-three. He subsequently had progressive aortic root and ascending aorta dilation to 9 cm. The aortic root and ascending aorta replacement was done using a composite valve-graft and was performed along with other procedures. Thus, meticulous follow-up of aortic root and ascending aorta after corrective surgery for tetralogy of Fallot is recommended following initial curative surgery.
