Subannular aortic aneurysm is a word-wide rare disease entity occurring predominantly in young black men. In Korea, there has been no report. We report one patient, 46 years old man, who had been operated urgently because of acute aortic insufficiency and aortic valvular vegetation after antibiotics treatment of Subacute bacterial endocarditis for 6wks. At the operative field, We found the bulging aneurysmal mass between the aorta and superior vena cava above the right pulmonary artery, which has subannular communicating opening into the left ventricular cavity, beneath the anterior commissure of the bicuspid aortic valve. Pathologic findings are consistent with "portion of vascular wall with features of aneurysm.* The patients survived aortic valve replacement and patch closure of subannular aneurysm, with no symptoms at one-year postoperative follow-up.w-up.

After the first report of mitral stenosis as a cause of recurrent laryngeal nerve palsy by Ortner in 1897, many authors have described that some kinds of cardiovascular disease might contribute to the development of recurrent laryngeal nerve palsy. The estimated rate of aortic aneurysm related with recurrent laryngeal nerve palsy is about 5%. Aortic aneurysm is classified into 3 types according to the involving segment of aorta in which aneurysms develop, and the first class-aneurysm in ascending aorta and aortic arch-is known to be the only type related to recurrent laryngeal nerve palsy. Recently we experienced two cases of recurrent laryngeal nerve palsy each of which had aneurysm on aortic arch as a major contributing factor. We report these cases with brief review of the literature.

원위 흉부 대동맥이나 복부 대동맥 혹은 두 부위가 좁아져 있는 Middle aortic syndrome (이하 MAS) 또는 mid aortic dysplastic syndrome은 매우 드물게 발생한다. 원인이 불분명하고 흔히 젊은 여성에게서 잘 나타나는 이 질환은 뇌출혈뿐만 아니라 심장, 신장의 손상을 초래할 수 있으므로 적극적인 수술적 치료로 혈류를 개선하여 효과를 볼 수 있으나 대동맥 혈관의 섬유화로 인한 수술 술기의 어려움이 따른다. 최근 국립의료원 흉부외과에서는 광범위한 석회화 병변을 동반한 하부 대동맥협착을 가진 51세 여자 환자에서 6.0-mmPTFE (polytetrafluoroethylene) 인조혈관을 이용하여 양측 액와-대퇴 동맥간 우회로술을 시행함으로써 우수한 수술 결과를 보였기에 보고하는 바이다.

We retrospectively studied 34 patients who underwent operations of ascending aortic aneurysm and aortic valve replacement from August 1979 to July 1992 at the Yonsei Cardiovascular Center. Eight patients underwent supracoroanry non-composite graft replacement and separate aortic valve replacement[group I]. Twenty six patients underwent valved composite graft replacement with reimplantation of coronary arteries[group II]. Two cases in group II died within 1 month after the operation. Among the 32 survivors 28 patients have been followed up for an average of 59 months ranging from 1 months to 159 months. During the follow up periods, a pseudoaneurysm around the ascending aorta and a newly developed dissecting aneurysm in remaining aorta were noted in group II. There were 6 late deaths: 2 cases in group I and 4 cases in group II. Three cases among the 6 late deaths have stigmata of Marfan`s syndrome[1 cases in group I and 2 case in group II]. There was no statistically significant difference in actuarial survival rates between group I and group II[p > 0.05]. This study suggests that non-composite supracoronary graft interposition with separate aortic valve replacement is a safe surgical technique in patients who have normal aortic annulus and normal position of coronary ostia. However in degenerative disease such as cystic medial necrosis, composite graft replacement is recommended because this procedure eliminates entire abnormal tissue.But it seems to be important that the suture technique and strict follow-up in patients with diseased aortic wall.

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.

Marfan 증후군과 같은 대동맥 질환의 경우 대동맥동 및 대동맥륜의 점진적인 확장 및 변형이 발생하여 대동맥판막의 폐쇄부전을 초래한다. 이런 경우 대부분 상행대동맥과 대동맥 판막을 composite graft의 형태로 치환하고 여기에 관상동맥을 문합하는 술식이 적용되어왔다. 본 증례는 Marfan 증후군이 동반된 22세 남자 환자로 대동맥 근부 확장과 승모판막 부전이 있었다. 수술은 대동맥 판막 및 좌심실유출로의 일부를 보존하면서 상행대동맥 및 Valsalva동의 동맥류를 제거하고, 대동맥 판막 및 관상동맥을 인조혈관에 다시 문합하는 술식을 적용하였다. 술후 심초음파 검사상 대동맥 판막의 기능은 정상이었다. 대동맥륜 확장증에 있어서 대동맥 판막이 정상적인 해부학적 구조를 가진다면 이상의 술식을 적용함으로써 자신의 대동맥 판막은 보존하면서 대동맥 근부를 치환할 수 있으리라 생각된다.

Surgery is now the usual mode of therapy in patients with severe valvular heart disease. Until recently, clinicians and pathologists attributed nearly all acquired valvular heart diseases to a rheumatic origin, except some obviously resulting from acute infection and syphilis. Although many clinicians and pathologists describe that the origin of aortic valvular disease is a nonrheumatic origin, we recognize the major origin of aortic valvular disease in Korea as a rheumatic origin. We excised 47 cardiac valves from valvular heart diseased patients and performed anatomical and pathological analysis for its origin and underlying pathology. The purpose of this article is to provide an update for the clinicians of evolving issues related to the pathology of valvular heart disease. But myxomatous origin and infective endocarditis valvulitis will not be covered in detail.

From January 1988 to December 1990, 18 adult patients with aortic disease underwent surgical repair using hypothermia and total circulatory arrest. The age at operation ranged from 17 years to 64 years[mean 45.2$\pm$10.7 years]. We disease entities included aortic dissection in 12, aortoannuloectasia in 3 and thoracic aortic aneurysm in 3 cases. Partial cardiopulmonary bypass via femoral vessels along with surface cooling was used upon the induction of deep hypothermia[18~20oC]. Modified Bentall operation was performed in 7 cases, ascending aorta replacement in 6, graft interposition in descending thoracic aorta in 3 and others in 2 cases. The circulatory arrest was maintained for periods of 2 minutes to 86 mimutes[mean 34.7$\pm$5.0 minutes]. Overall hospital mortality was 27.8%[5/18]: brain damage was responsible for the death of 2 patients. 4 patients out of 13 survivors experienced postoperative neurologic dysfunction, which was proved to be self-limited except one case showing left hemiparesis. 12 patients were followed up postoperatively with the mean follow-up period 22.7$\pm$10.1 months. There was no death. No new neurologic problems were observed during follow-up period. All but one patient showing recurrent dissection and aortic regurgitation are in exellent clinical condition. These clinical data suggests that the principle of deep hypothermia and total circulatory arrest can be applied rather safely in adult patients, especially in the treatment of patients with aortic disease, it can be a valuable adjunct with better clinical results.

세균성 심내막염에 의한 대동맥판 폐쇄부전의 수술치료에 있어서, 우수한 혈역학적 기능과 염증에 대한 높은 저항력 때문에 동종대동맥판을 사용한 수술이 우선적으로 고려되고 있다. 수술방법중에서 대동 맥근부 치환술이 관상동맥하 부착법에 비하여 술 후 대동맥관 폐쇄부전이 적게 발생하는 장점을 갖는다. 46세의 남자가 세균성 심내막염에 의한 급성 대동백판 폐쇄부전 및 심부전으로 내원하였다. 내과적 치료에 반응하지 않고 심부전이 점차 심해져서 20 m동종대동맥편을 이용한 대동맥근부 치환수술을 응급으로 시행하였다. 수술소견상 우관상판첨에 구멍이 나 있었고 좌, 우관상판첨사이의 교련에 심한 석회화가 있었다. 수술후 환자는 순조로이 회복되었고 심초음파검사상 이식된 동종동맥 판의 폐쇄부전소견 은 발견되지 않았다. 염증소견들도 술 후 8주간의 항생제투여로 소실되었다. 약물치료로 조절되지 않는 세균성 심내막염에 의한 급성 대동맥판 폐쇄부전을 동종동맥 판을 사용한 대동맥근부 치환수술로써 성 공적으로 치료하였다.

Takayasu씨 동맥염 환자에서 대동맥판막 폐쇄부전은 종종 발생하는 합병증이다. 급성 및 진행성 염증으로 대동맥의 뇌혈관 분지에 협착 또는 폐쇄를 가진 환자에서 실신 등의 허혈성 뇌증상은 대동맥판막 폐쇄부전증의 합병으로 더 악화될 수 있다. 양측 경동맥의 폐쇄와 양측 척추동맥의 협착, 우관상동맥의 폐쇄, 대동맥판막 폐쇄부전증으로 실신 및 호흡곤란을 호소하는 34세 남자 환자에서 수술 전후에 스테로이드의 투여, 양측 쇄골하 동맥에 스텐트의 삽입 및 대동맥판막 치환술로써 증상의 호전을 가져올 수 있었다.
