A 61-year-old man was diagnosed with aortic stenoinsufficiency with periannular abscess, which involved the aortic root of noncoronary sinus (NCS) that invaded down to the central fibrous body, whole membranous septum, mitral valve (MV), and tricuspid valve (TV). The open complete debridement was executed from the aortic annulus at NCS down to the central fibrous body and annulus of the MV and the TV, followed by the left ventricular outflow tract reconstruction with implantation of a mechanical aortic valve by using a leaflet of the half-folded elliptical bovine pericardial patch. Another leaflet of this patch was used for the repair of the right atrial wall with a defect and the TV.

Complete and optimal visualization of the mitral apparatus is a prerequisite for accurate repair or replacement of the mitral valve. A vertical left atriotomy just posterior to the interatrial groove is the most commonly used approach. However,exposure can be difficult under certain circumstances,such as small left atrium or reoperation. Other approaches have been advocated to deal with this difficult situations. We used an extended transseptal approach in 10 patients and good clinical results and excellent educational effects were obtained. The extended transseptal approach combines two semicircular atrial incisions circumscribing the tricuspid and mitral annuli anteriorly and superiorly,allowing exposure of the mitral valve by deflecting the ventricular side using stay sutures. The right atrium is opened anteriorly along the atrioventricular sulcus. The atrial septum is incised vertically through the fossa ovalis. Right atrial and septal incisions are joined at the superior end of the interatrial septum and extended across the dome of the left atrium to the left atrial appendage. The mitral valve was replaced in all 10 patients. Four of 10 patients had other simultaneous valve procedure: one had aortic valve replacement: 2 underwent tricuspid annuloplasty: 1 had aortic valve replacement and tricuspid annuloplasty. There was no hospital death and complication. Among the 5 patients who had atrial fibrillation preoperatively,4 had atrial fibrillation postoperatively,1 converted to sinus rhythm. The five patients who were in normal sinus rhythm preoperatively remained in sinus rhythm after replacement. A review of our results with this approach confirms the efficacy and safty of this method. So we recommanded this approach for routine mitral valve procedure,especially difficult situations,such as a small left atrium or the redo operation.

One hundred cases of open heart surgery were done at this Department in 1977. There were 65 congenital anomaly and 35 acquired diseases. Out of 65 cases of congenital malformation 35 acyanotic and 30 cyanotic cases were found. Fifteen cases of ventricular septal defect and 29 tetralogy of Fallot were noted eight patients expired out of 65 congenital anomaly [12.3%] , 4 out of 35 acyanotic [11. 4%] and 4 among 30 cyanotic anomaly[13.3%]. Among 35 cases of acquired heart disease 3 atrial myxoma [2 left and one right] and 32 valvular lesions were noted. In two cases open mitral commissurotomy, and in 30 valve replacement were done. Twenty-two single valve and 8 double valve replacement were done. Seven patients expired out of 30 patients [23.3%]. Among 22 single valve replacement cases 2 and among 8 double valve 5 died. ~ In eighteen mitral valve replacement cases 2 deaths occurred. One mitral insufficiency patient who expired suffered from severe pulmonary` hypertension [PA=120/67mmHg], tricuspid insufficiency and a large ventricular septal defect. The patient underwent mitral valve replacement, tricuspid annuloplasty and patch closure of ventricular septal defect. Over all mortality rate for 100 open heart surgery cases was 15%. Since 1977 open heart surgery cases were done routinely in this institution and cases are increasing rapidly. With present rapid improvement of economical status and introduction of medical insurance system, open heart surgery will be firmly established in Korea in the very near future.

From Jan 1982 through Dec.1991, thirty-three DeVega`s tricuspid annuloplasties were performed in association with mitral and combined mitral and aortic valve disease. Preoperatively,all of the patients were in NYHA functional class III or IV.There were one early death and 4 patients died during follow up period of 18 to 138 months [ mean follow up : 67.3 months ]. Nine patients required reoperation because of biological mitral valve failure at 4.7 to 11 years after tricuspid annuloplasty[TAP]. Among these patients,2 cases needed for reoperation of TAP due to loosening of suture material. Twenty four [86%] of the survivors were in NYHA functional class I or II after TAP.The actuarial survival rate for the TAP was 74% at 138 months. Rt atrial pressure of 9 reoperation cases were significantly decreased [P<0.05] compared with initial Rt.atrial pressure [ Mean period; 93.6 months].Doppler echocardiographic studies for tricuspid regurgitation were performed in 15 cases after TAP [Mean period: 42.3 months].These results showed significantly reduced [P<0.01] tricuspid annulus diameter and tricuspid regurgitation distance [ P<0.05 ].Our surgical experience that the DeVega`s TAP is a simple,safe,effective procedure and resulted in good hemodynamic improvement with moderate to severe functional tricuspid regurgitation.

일시적인 삼첨판 절개법은 좋은 시야를 제공하고 심실을 열지 않고 심실중격결손의 폐쇄수술을 할 수 있다. 그러나 대부분의 외과의는 삼첨판막의 폐쇄부전의 염려로 주저하게 된다. 특히 최근의 교과서에서는 일시적인 삼첨판 절개법은 장기성적의 발표가 예외적인 방법으로만 기술되어 있고 더 이상의 분석이나 기술이 되어 있지 않다. 대상 및 방법: 1985년부터 1994년까지 수술받은 11명으로부터 술 전의 자료, 술 후 경과, 최근 심초음파와 심전도를 토대로 후향적 연구를 시행하였다. 결과: 심초음파에서 삼첨판폐쇄부전은 없는 경우가 9명, 미세한(trivial) 경우가 2명이었고, 심전도상 의미있는 심전도블록은 없었다. 결론: 삼첨판 절개법은 심실중격결손의 폐쇄수술을 시행하는 데 안전하며 향상된 시야를 제공하는 데 효과적인 방법이며, 삼첨판 이상이나 심전도상에 나쁜 영향을 끼치지 않는다.
