A 53-year-old man presenting with dyspnea and chest pain was diagnosed with acute myocardial infarction secondary to occlusion of the left circumflex coronary artery. Urgent revascularization by percutaneous stenting was successfully performed. However, the post-echocardiography revealed a ruptured papillary muscle that was causing severe mitral regurgitation and aggravation of congestive heart failure. The patient subsequently underwent mitral valve repair with papillary muscle re-implantation. Postoperative echocardiography showed a competent mitral valve without residual stenosis or regurgitation. The patient was discharged from the hospital with an uneventful recovery and has been doing well on outpatient follow up.

Sixty cases of open heart surgery were performed in the Department of Thoracic and Cardiovascular Surgery of Chonbuk National University Hospital from July, 1983 to June, 1984. The patients were consisted of 40 [66%] congenital anomalies containing 26 [43%] patients of acyanotic group and 4 [23%] of cyanotic group, and 20 [34%] acquired heart diseases which involved one or more cardiac valves. The male patients were 42 and the female 18. In 20 valvular heart diseases, open mitral commissurotomy was done in 5 patients, mitral valvular replacement with tissue valve in 6, mitral valvular replacement with mechanical valve in 5, mitral valvular replacement with tricuspid annuloplasty in 2, mitral annuloplasty in 1, and mitral and aortic valvular replacements with mechanical valves in 1. The most frequency complication was low cardiac output syndrome occurred in 9, and the next was urethral stenosis, ARDS, and postoperative bleeding, etc. The perioperative mortality was 21% in congenital cyanotic heart disease, 12% in congenital acyanotic heart disease, and 5% in acquired heart disease.

배경: 심장 점액종에 대한 진단과 수술적 치료는 성공적으로 시행되어 왔다. 그러나 양호한 수술적 치료의 결과에도 불구하고 심장 점액종은 수술 전 심장 내 혈류 폐쇄 및 색전증 등의 치명적인 합병증을 유발할 수 있으며 수술 후 재발할 수 있는 질환이다. 대상 및 방법: 1994년 11월부터 2007년 6월까지 심장 점액종으로 수술 받은 환자 85명을 대상으로 의무 기록 검토를 통해 수술 전 임상적 특징, 수술적 치료의 결과 및 재발에 관하여 후향적 분석을 시행하였다. 또한 좌심방 점액종 환자 58명에서 수술 전 심초음파 결과를 토대로 종양의 형태학적 특성을 분석하고 이와 기능성 승모판막 협착증 및 전신 색전증 발생과의 상관 관계를 분석하여 수술 전 위험인자를 알아보았다. 결과: 환자의 평균나이는 $54.5{\pm}14.3$세로, 남자가 27명(31.8%), 여자가 58명(68.2%)이었다. 수술 전 증상은 심장 내 혈류 폐쇄에 의한 증상이 41예(48.2%), 색전 증상이 19예(22.4%), 전신 증상이 8예(9.4%), 무증상이 19예(20.0%)였다. 좌심방 점액종 58예에서 종양의 평균 장경은 $4.3{\pm}1.8$ ($1.1{\sim}8$) cm이었고, 심실 이완기에 승모 판막륜(mitral valve annulus)의 하방까지 종양이 이동하는 탈출형(prolapsing type)이 26예(44.8%),표면에 다수의 섬세한 돌출이 있는 융모형(villous type)이 32예(55.2%)였다 그리고 수술 전 중증의 기능성 승모판막 협착증(functional mitral stenosis)이 유발된 경우는 12예(20.7%), 전신 색전증(systemic embolism)이 발생한 경우는 15예(25.9%)였다. 중증의 기능성 승모판막 협착증의 발생율은 탈출형이 비탈출형에 비해 유의하게 높았으며(p=0.001),중증의 기능성 승모판막 협착증이 발생한 경우의 종양의 평균 장경은 $5.1{\pm}1.0\;cm$로 그 외의 경우보다 유의하게 큰 것으로 나타났다(p=0.041). 또한 전신 색전증의 발생율은 융 매끄러운 형보다 유의하게 높았다(p=0.006). 수술 후 합병증은 6예(7.1%), 조기 사망은 1예(1.2%)에서 있었다. 수술 후 평균 추적관찰 기간은 $36.2{\pm}37.5$ ($0{\sim}138$)개월이었고 재발은 2예(2.4%)에서 발생하였으며 재발된 기간은 각각 48, 12개월이었다 결론: 심장 점액종에 대한 수술은 안전하게 시행되었고, 장기적 예후 또한 양호하였다. 좌심방 점액종에서 탈출형과 종양의 장경이 큰 경우에 기능성 승모판 협착증 발생의 위험인자가 되며, 융모형인 경우에 전신적 색전증 발생의 위험인자가 되므로 이러한 경우 특별한 주의를 요하며 수술 전 합병증 발생의 예방을 위하여 가능한 빨리 수술을 시행하여야 한다. 또한 재발과 관련하여 심초음파 검사를 통한 정기적 추적관찰이 필요하다.

A clinical analysis was performed on 48 cases with mitral stenosis who received open mitral commissurotomy from December 1983 to June 1991 at the Department of Thoracic & Cardiovascular Surgery, Chungnam National University Hospital. Fifteen patients were men and 33 were women. the mean age was 35.6 years with the range of 16 to 61 years. The distribution of preoperative NYHA Functional Classes was as follows; class II, 25 patients; class III, 20 patients; class IV, 3 patients. Three patients had cerebral emboli preoperatively, all of whom were in atrial fibrillation. The preoperative electrocardiographic studies revealed that 32 patients had sinus rhythms and 16 had atrial fibrillations. Twenty-six patients had open mitral commissurotomy alone and 22 patients had additional cardiac procedures. Intraoperatively, there were 6 cases of left atrial thrombosis. There was no perioperative death but early postoperative complications were found in 3 cases. The patients were followed up from 2 to 99 months[mean 33.7 months . There was one case of late unexplained sudden death. There was a case of late postoperative cerebral infarction, 5 cases of mitral restenosis and 3 cases of congestive heart failure and/or arrhythmia. Mitral valve replacements were required in 3 patients.But, it is evident that open mitral commissurotomy has many advantages beyond mitral valve replacement concerning the results of the mitral valve replacement underwent during the same period at the Department of Thoracic & Cardiovascular Surgery, Chungnam National University Hospital.

The present study reports 41 cases of congenital and acquired heart diseases, who received open heart surgery under extracorporeal circulation [ECC] by Sarns Heart-Lung-Machine [HLM] at the Department of Thoracic and Cardiovascular Surgery, Hanyang University Hospital during the` period between July 1975 and February 1979. The priming of pump oxygenator was carried out by the hemodilution method using Hartman`s solution, whole blood, and fresh human plasma. The rate of hemodilution was in the average of 50.8 ml/kg. ECC was performed at the average perfusion flow rate of 85.0 ml/kg/min [2.43 L./ kg/2] and at moderate hypothermia. In the total cardiopulmonary bypass, arterial pressure ranged between 55 mmHg and 90 mmHg, but generally maintaining over 70 mmHg. Patient age ranged between 2 and 54 year old, in congenital heart diseases, between 2 and 28, in acquired heart diseases, between 17 and 54 Sex ratio of male to female was 20:21. The cases include a case of pulmonary valvular stenosis, 4 cases of atrial septal defect, 9 cases of ventricular septal defect, 9 cases of tetralogy of Fallot, 5 cases of pentalogy of Fallot, 3 cases of atypical multiple anomalies 7 cases of mitral stenosis or insufficiency, a case of myxoma in left atrium, and a case of ruptured aneurysm of Valsalva`s sinus. The surgical managements were 16 valvulotomy for pulmonary valvular stenosis, 2 Teflon patch graft closure and 5 simple suture closure of atrial septal defect, 16 Teflon patch graft closure and 5 simple suture closure of ventricular septal defect, 12 pericardial patch graft for infundibular stenosis of right ventricle, one anastomosis between left superior vena cava and right atrium, 2 open mitral commissurotomy, 5 mitral valve replacement using Starr-Edward`s ball valve, porcine xenograft by Hancock, by Carpentier-Edward, or Angell-Shiley, one removal of left atrial myxoma, and a repair of ruptured aneurysm of Valsalva`s sinus. Four [9.7%] out 41 cases expired postoperatively and the rest of 37 cases survived with satisfactory results. The causes of death were one coronary embolism in tetralogy of Fallot, 2 postoperative lower cardiac output in atypical multiple anomalies, and one right heart failure in large: ventricular septal defect with pulmonary hypertension.

A hundred and eleven patients of mitral valvular heart disease, who were operated at Seoul National University Hospital, were analysed with echocardiogram before and after operation during the period from November 1979 to February 1982. Twenty-eight patients had mitral stenosis and eighty-three mitral regurgitation. In patients with mitral stenosis, right ventricular end-diastolic volume was in normal range at preoperative and postoperative period. But the left ventricular end-systolic volume was slightly increased preoperatively to 35.4mm and decreased to 33.5mm on immediate postoperative period and 32.5mm after a year later. The left ventricular end-diastolic volume was 50.5mm preoperatively and fell to 46.8mm postoperatively. Ejection fraction was normal preoperatively and postoperatively without changes. Left atrial size fell significantly from 50ram to 37.6mm at the time of late follow-up study. With mitral regurgitation, right ventricular end-diastolic volume was also normal preoperatively and postoperatively. The left ventricular end-systolic volume was increased to 41.9mm and decreased to 31.6mm postoperatively with statistic significance. Left ventricular end-diastolic volume fell from 58.5mm to 45.7mm significantly at the time of late follow-up period. Ejection fraction was also within normal range and had no changes postoperatively. Left atrial size fell from 54.8mm to 45.5mm on a year later [ p value less than 0.01 ]. When atrial fibrillation, the left atrial dimension was increased as 54.9mm compared with 46.8mm of no atrial fibrillation patients.

To improve the prognosis of mitral valve replacement surgery, analysis and evaluation of pre and intra operative risk factors will be very much valuable. Author studied 205 cases of mitral valve replacement from Feb 1982 to June 1989 for the risk factors of hospital death. 90 patients were male and 115 were female, and age was from 16 to 59 years, Mitral stenosis dominant lesions were 91 cases and regurgitation 114. Suspected risk factors were NYHA functional class, cardiothoracic ratio, implanted valve type and size, operation time, age and sex, thrombus in left atrium, atrial fibrillation, aortic cross clamping time, left ventricular end diastolic and systolic dimension, nephropathy, hepatopathy and respiratory insufficiency. Statistic analysis was performed by X2 test between survivors and death group. Statistical significances as pre and intraoperative risk factors of hospital death after mitral valve replacement were confirmed in those presence of AF on the EKG, NYHA functional class[>IV], cardiothoracic ratio[>70%], and implanted valve size[>33mm]

From 1958 up to the end of April 1980, during the period of 12 years 1640 cardiac surgery cases including 1069 open heart surgery and 304 valve replacement cases, were operated in this Department. There were 1070 congenital anomaly and 570 acquired disease cases. In 1070 congenital anomaly cases 673 acyanotic and 397 cyanotic anomaly patients were noted. In acquired diseases 94 pericardial and 456 valvular cases were found. Among 456 valve cases 189 mitral stenosis, 133 mitral insufficiency, 30 aortic valve lesion, 97 double valve, and 7 triple valve lesion patients were noted. Among 304 valve replacement cases 209 mitral, 34 aortic, 5 tricuspid, 34 aortic with mitral, 20 mitral with tricuspid, and 2 triple valves were replaced. Annual increase `of open heart surgery cases and decrease of operative deaths were remarkable in recent years. In recent years Shiley** oxygenator in pump-oxygenator set up and Ionescu** bovine pericardial xenograft bioprosthesis were used for valve replacement mainly.
