Between April 1976 and March 1978, six cases of tricuspid valve replacement were done in the Department of Thoracic Surgery, Seoul National University Hospital. There were 4 men and 2 women and the age of the patients ranged from 17 years of the youngest to 48 years of the oldest. Most of them had characteristic symptoms of tricuspid valve disease, such as a systolic murmur audible over the lower sternum and varying with respiration, pulsatile and distended neck vein, and an enlarged and pulsatile liver. Preoperative functional levels according to NYHA Calcification were class III in 4 cases, and class IV in 2 eases. Most of the cases showed moderate to severe cardiomegaly in chest films and elevated right atrial pressure on preoperative right heart catheterization. Five of them underwent concomittent mitral valve replacement and one pulmonary valvotomy. All of them showed tricuspid insufficiency resulted from massive dilatation of annulus, destructive lesions of valve structure, or both anomalies. One postoperative hospital death was encountered and the cause of death was low out-put syndrome. All survivors showed clinical improvement and cardiomegaly regressed and left hospital in a good condition . *Attendum; Recently 2 more cases of tricuspid valve replacement with mitral valve replacement were done after this review.

Between Jan. and Oct. 1978, mitral valve Replacement had been performed on eight patients using porcine aortic valve mounted on flexible polypropylene or Egyloil wire and Dacron covered stent. Mitral valve replacement was performed on five, mitral valve replacement with tricuspid valve replacement on two, and mitral valve replacement with tricuspid valve annuloplasty on 1 patient using five Carpentier and five Hancock Xenograft. Overall operative deaths were 2 cases. All other 6 cases did well after surgery and improved. No systemic thromboembolism occurred without anticoagulant-No valve failure took place. The results are satisfactory.

A total of 63 patients [42 males and 21 females] underwent multiple valve replacement with artificial valves between January 1975 and August 1980 at Seoul National University Hospital. There were 38 patients with aortic and mitral valve replacement, 22 with mitral and tricuspid, and 3 with aortic, mitral and tricuspid valve replacement. The valve lesions varied from trivial to severe and most aortic and mitral valves had mixed stenosis and insufficiency, while tricuspid valves had only insufficiency. The patients were severely symptomatic in majority of the cases, and belonged to the Classes III and IV [III:45, IV:16] of the NYHA functional criteria. Hemodynamic studies were performed on all the patients. The mean pulmonary wedge pressure was remarkably increased to 19.8 mmHg in aortic and mitral valve lesions and 18.0 mmHg in mitral and tricuspid valve lesions. The mean pulmonary arterial pressure was also increased, while the cardiac index was reduced. In 1977, the average perfusion time was 245.5 minutes for aortic and mitral valve replacement and 181.6 minutes for mitral and tricuspid valve replacement. It has progressively declined to 169.2 minutes for aortic and mitral valve replacement and 123 minutes for mitral and tricuspid valve replacement in 1980. The average period of aortic occlusion also declined after the use of cardioplegic solution. Twenty deaths occurred among the 63 patients operated upon, an overall mortality rate of 30.8%. The operative mortality has declined with successive year from a level of 66.7% before 1977 to 21.1% in 1980. Fourteen patients suffered from a list of postoperative complications, which eventually resolved with adequate treatment. All the survivors were enjoying the levels of daily life activities greater than those existing before the operation.

배경: 삼첨판막친환술은 매우 드물게 시행되는 수술이며 그 장기 성적은 만족치 못한 수준이다. 또한 어떤 종류의 인공판막을 사용하느냐에 대하여도 논란이 많은 상황이다. 서울대학교병원 흉부외과에서는 1989년 1월부터 1998년 12월까지 10년동안 71명의 환자에서 72례의 삼첨판막 치환술을 시행하였으며 이 결과를 토대로 장단기 성적과 위험요인들을 분석하였다. 대상 및 방법: 평균나이는 42$\pm$13세(16~65세)였으며 남여비는 32/39였다. 술전진단은 50례의 후천성판막질환과 18례의 선천성심장질환이 있었고 삼첨판폐쇄부전만 단독으로 있었던 경우도 4례 있었다. 사용된 인공판막은 기계판막이 69개, 조직판막이 3개였다. 승모판막치환술 또는 대동맥판막치환술과 같이 시행된 경우는 50례였고 1례에서는 폐동맥판막 치환술이 같이 시행되었다. 결과: 조기사망은 7례(9.7%), 만기사망은 7례(13.0%)였고 10년 생존율은 59.2$\pm$7.2%였다. 삼천판막혈전증은 5례에서 11번에 결쳐 발생하였으며 그중 1례는 재수술을 시행받았다. 생존자들의 대부분은 심장기능분류 I-II의 상태로 현재까지 외래 추적관찰중이다. 결론: 삼첨판막치환술은 비록 혈전증등의 위험이 상존하기는 하지만 비교적 낮은 사망률과 이환율을 보이고 있으며 기계판막의 경우에도 조직판막과 비교하여 큰 차이 없이 좋은 장기성적을 얻을 수 있었다.

Seventy eight patients underwent operation for combined multiple valve disease, with an overall early mortality of 14.1 % from January, 1983 to September, 1988 in the department of thoracic and cardiovascular surgery of Pusan National University Hospital. All of the above cases had combined multiple valve procedures. There were 33 mitral valve replacements and tricuspid annuloplasties, 33 aortic and mitral valve replacements, 5 aortic and mitral valve replacements with tricuspid annuloplasties, 3 aortic valve replacements and mitral annuloplasties, 1 open mitral commissurotomy and tricuspid annuloplasty and, 1 mitral valve replacement and primary closure of tricuspid valve cleft, 1 mitral valve replacement and aortic commissurotomy, 1 mitral, aortic and tricuspid valve replacement were done. 44 were male and 34 were female and the age distribution was from 14 to 57 with mean 38 year old. According to NYHA[New York Heart Association] classification, 49 patients were class I, 19 patients were class Il and 10 were class IV. Average perfusion time was 205.3 minutes. The live patients perfusion time was 178.7 minutes while that of dead ones was 272.0 minutes. Early deaths within 30 days from operation were 11 cases, 6 of which were due to low cardiac output, 3 were acute renal failure and 2 were cardiac rupture. The 65 patients were followed up from 2 to 30 months for a total 20.6 patient years. 1 patient committed suicide because of postoperative depression 1 year after operation. All of the survivors were enjoying their daily life and their NYHA class was superior to the preoperative ones.

We report the case of a female patient who underwent late reoperation following endocarditis surgery. The patient first underwent surgery at 22 years of age for endocarditis with aortic and tricuspid insufficiency. She underwent aortic root replacement with a homograft and tricuspid valve replacement with a tissue valve. Coronary artery bypass using the internal thoracic artery and ligation of the left main coronary artery were performed. Ten years later, failure of the homograft and the tricuspid valve developed. In the second operation, the patient underwent a successful Bentall operation and tricuspid valve replacement with a mechanical valve under deep hypothermia and retrograde cold cardioplegia without drainage.

Ebstein`s anomaly is characterized by a downward displacement of a malformed tricuspid valve, The ideal surgical management of Ebstein`s anomaly is not yet established. Recently we experience one case of Ebstein`s anomaly, which was treated sussessfully by partial artificial annulus formation, and tricuspid valve replacement with St. Jude Medical valve. We have achieved excellent results with mechanical valve replacement and partial artificial annulus formation using wessex pericardial patch. On follow up for 4 years, the patient is well and in functional class I.

From April, 1982 to December, 1992, multiple valve replacement was performed in 100 patients. Mitral and aortic valve replacement were done in 86 patients, 9 underwent mitral and tricuspid valve replacement, 4 patients underwent triple valve replacement and 1 patient underwent aortic and tricuspid valve replacement. Of the valve implanted, 100 were St. Jude, 64 Duromedics, 19 Carpentier-Edwards, 13 Bj rk-Shiley, 6 Ionescu-Shiley, and 2 Medronics.The hospital mortality rate was 15%[15 patients] and the late mortality rate was 7%[7 patients], the mortality rate was high in early operative period but decreased with time[20% at 1986, 18.2% at 1987, 9.5% at 1988, 11.1% at 1989, 12.5% at 1990, 11.8% at 1991, 0% at 1992]. The causes of death were low cardiac output in 8, sudden death in 3, CHF in 3, bleeding in 2, cerebral thromboembolism in 1, leukemia in 1, multiorgan failure in 1 and so on. The actuarial survival rate excluding operative death was 73% at 10 years.

삼첨판막대치술의 장기 결과에 대한 연구결과는 보고된 바가 많지 않다. 이에 저자들은 삼첨판막대치술의 위험인자를 분석해 보고, 삼첨판막대치술의 장기 결과를 알고자 연구를 시행하였다. 대상 및 방법: 대상 환자들은 1978년 10월부터 1996년 12월까지 삼첨판막대치술을 시행 받은 환자 70명을 대상으로 후향적인 연구를 진행하였는데, 7명의 환자들은 2차례의 삼첨판막대치술을 시행 받아 총 77예의 삼첨판막대치슬을 시행하였다. 환자들의 평균 나이는 38.8$\pm$15.9세였으며, 26예에서는 조직판막을, 51예에서는 기계판막을 이식하였다. 결과: 수술 사망률은 15.6%였고, 만기 사망률은 12.3%였다. 5년, 10년 그리고 13년에서의 생존율은 조직판막과 기계판막이 각각 81.3% vs. 100%, 66.1% vs. 100%, 60.6% vs. 100%였다(p=0.0175).판막과 관련된 재수술이 없을 확률은 5년, 10년 그리고 13년에서 조직판막과 기계판막이 각각 100% vs. 93.9, 100% vs. 93.9% 그리고 58.3% vs. 93.9%였다(p=0,3274). 판막과 관련된 재수술을 시행할 확률은 조직판막이 2.27%/환자-년이었고, 기계판막이 1.10%/환자-년이었다. 수술 사망과 관련된 위험인자 분석상, 수술 전 복수, 간비대, NYHA class가 나쁠수록, 그리고 삼첨판막대치술을 여러 번 받는 경우가 유의한 위험인자로 분석되었고, 조직판막의 사용과 심장수술을 여러 번 받는 경우가 만기 사망과 관련된 유의한 위험인자로 분석되었다. 걸론: 기계판막을 이용하여 삼첨판막대치술을 시행한 환자들의 장기간 생존율이 조직판막을 이용한 환자들보다 우수하였다. 따라서 수술 후에 적절한 추적관찰이 가능하다면, 기계판막을 이용하여 삼첨판막대치술을 시행하는 것이 필요하리라 생각한다.
