A 30-year-old male with a symptomatic aberrant right subclavian artery underwent surgical intervention on January 17, 1990. An aberrant right subclavian artery is a rare congenital anomaly, but it is the most common one of the aortic arch anomalies. This anomalous vessel usually does not produce symptoms, but occasionally symptomatic patients require surgical intervention. Although ligation and division of the aberrant right subclavian artery through left thoracotomy has been advocated by many surgeons, the ischemic symptoms of the upper extremity or the brain can occur. In the procedure described here, ligation and division of the aberrant artery and its anastomosis to the ascending aorta with Gore \ulcornerTex vascular graft was performed simultaneously through midsternotomy. With this procedure, we relieved the esophageal obstruction and established normal blood flow to the right arm. Hoarseness developed postoperatively. We consider that above symptom has been attributed to the injury of the left recurrent laryngeal nerve during dissection.

The association of aortopulmonary window and tetralogy of Fallot is rare. The aortopulmonary window lies usually between the left side of the ascending aorta and the right wall of the pulmonary artery just anterior to the origin of the main pulmonary artery. Recently, we experienced a case of aortopulmonary window associated with tetralogy of Fallot in a 4 years old male. Operation was done under the Impression of the tetralogy of Fallot. On operation, the anomaly was confirmed as aortopulmonary window[type 1] and tetralogy of Fallot. The aortopulmonary window was closed with Gortex patch via the main pulmonary artery and tetralogy of Fallot was repaired. Postoperative course was uneventful.

Supravalvular aortic stenosis is an uncommon, congenital narrowing of ascending aorta just above aortic valve. Eleven patients underwent an aortoplasty to relieve supravalvular aortic stenosis at Sejong General Hospital from July 1985 to December 1991. Age ranged from 5 to 14 years(median 9 years). There were 7 male and 4 female patients. Seven patients had characteristics of Williams' syndrome including elfin face and mental retardation. All patients had localized, hourglass type but 4 patients had atypical findings. Preoperative left ventricula-aortic pressure gradient ranged from 40 to 190 mmHg(mean 88 mmHg). To relieve severe supravalvular aortic stenosis, extended aortoplasty was used in 7 patients and standard aortoplasty in 4 patients. Postoperative pressure gradient ranged from 0 to 40 mmHg (mean 16.6 mmHg). Follow-up pressure gradient with Doppler ranged from 0 to 88mmHg(mean 32.5mmHg).

A 50 year old man with acute aortic dissection DeBakey type I, involving right coronary artery and aortic valve, underwent replacement of the ascending aorta and aorto-right coronary bypass grafting. The operative findings showed a large transverse intimal tear was at about 4cm above the aortic valve. The dissection extended out into the proximal right coronary artery. And we found that the right coronary artery originated from the left sinus of Valsalva, run transversally in the aortic wall, with partial rupture. Postoperatively he had no ischemic cardiac symptoms and neurologic complications. He was discharged on postoperative 9th day with good result.

승모판막의 수술 시 승모판막에 접근하는 방법으로는 심방간 구(interatrial groove)를 따라 좌심방 절재를 통하거나 우심방을 절개한 후 타원오목(fossa ovalis)의 하변에서 심방중격을 절개하여 접근하는 방법이 대부분이다. 또 다른 방법으로는 상행 대동맥과 상대정맥 사이에 위치하고 있는 좌심방 Dome을 통해 승모판막으로 접근하는 방법이다. 비록 30년 전 좌심방 Dome을 통한 접근방법이 소개되었지만 널리 사용되지는 않았다. 저자들은 최근 승모판막 수술 시 좌심방 Dome을 통한 접근방법으로 효과적인 수술을 시행하였기에 문헌 고찰과 함께 소개하고자 한다.

Emergency operation was performed in a patient with severe aortic insufficiency caused by type A acute aortic dissection with aberrant high take-off origin of single coronary artery. The single coronary artery was found to arise from an unusual position high in the ascending aorta. Dissection was begun in the aortic root and involved the single coronary ostium. Valve competance was restored by resuspension of the commissures. the false lumen was obliterated with strips of Teflon felt and surgical glue. The aortic tissues were firmly reinforced and sutured. The proximal aortic stump was anatomically reconstructed, and fortunately the aortic valve was preserved and coronary reimplantation avoided. The patient was discharged at postoperative 13 days without specific complications. Postoperative course during the 18 months follow-up was uneventful.

A 6-year-old male German Shepherd was admitted to the Armed Forces Second Animal Clinic for clinical examination The symptoms were anorexia, dyspnea, emaciation and ascites. Treatment was given for a month but its condition did not improve, euthanasia was therefore performed and the dog was submitted for necropsy. A tumor was found at the base of the heart between the ascending aorta and the pulmonary artery It was diagnosed an aortic body tumor by clinical signs, gross lesions and histopathologic features.

From 1985 to 1990, a total of 160 new valves were implanted for 125 adult patients to whom prosthetic valve replacement had been performed [One patient had consecutive 2 reoperations]. Following data are the results from the follow-up study from January 1985 to February 1991. Mean age of the patients was 37.9$\pm$12.1 years. Mean follow-up period was 25.8$\pm$18.8 months. In bioprosthesis, mean interval between the previous operation and reoperation was 85.6$\pm$36.4 months in aortic valve, and 87.3$\pm$30.0 months in mitral valve. The causes of reoperation were prosthetic valve failure[103 patients, 81.7%], prosthetic valve endocarditis[17 patients, 13.5%], periprosthetic leakage[5 patients, 4.0%], and aneurysm of ascending aorta[1 patient, 0.8%]. Fourteen patients[11.1%] died in hospital; 5 in 22 replacement of aortic valve[22.7%], 6 in 73 rereplacement of mitral valve[8.2%], and 3 in 31 replacement of multiple valves [9.7%] Except for 3 intraoperative deaths, postoperative, major and minor complications occurred in 39 patients[31.0%]. And the actuarial 5-year survival rate of operative survivors was 95.5$\pm$8.6%.

A case of pulmonary atresia with intact ventricular septum was presented in a 10-month-old cyanotic female patient, which was congenitally rare. Infant with pulmonary atresia and intact ventricular septum usually require urgent surgical intervention. Angiogram showed the pulmonary atresia at the level of the pulmonary valve, the hypoplasia of tricuspid valve and atrial septal defect without patent ductus arteriosus. We performed the pericardial patch graft on the right ventricular outflow tract and pulmonary artery after ventriculotomy using pacemaker wire as electrical saw and main pulmonary arteriotomy and then modified Waterston shunt from the ascending aorta to patch on the right ventricular outflow tract without extracorporeal circulation. Patient was postoperatively good condition.

Neo-aortic insufficiency associated with root enlargement following an arterial switch operation is a serious late complication. To achieve successful surgical correction of this condition, multiple factors should be considered, including the individual patient's anatomy, the challenging nature of the redo procedure, and the patient's young age. However, limited publications have described the use of valve-sparing techniques for the treatment of neo-aortic insufficiency associated with root enlargement following an arterial switch operation. Herein, we report our recent experience of a valve-sparing aortic root procedure with ascending aorta and hemiarch replacement despite the presence of a discrepancy in leaflet size and nearby severe adhesions.
