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.

There were 29 cases of congenital heart anomalies (25％), and 85 cases of acquired heart diseases (75％) consisting of 53 cases of valvular heart disease, 31 cases of ischemic heart disease, and a case of left atrial myxoma. The age distribution of 114 cases was 4 to 73 years, and mean age was 43 years old consisting of mean age of congenital heart disease 23, valvular heart disease 47, and ischemic heart disease 57 years old.

Two hundred twenty one cases of open heart surgery were done in the Department of Thoracic and Cardiovascular Surgery, Pusan National University Hospital from July, 1981 to October, 1984. 1.There were 154 cases [73%] of congenital anomalies and 57 cases [27%] of acquired valvular heart diseases. Among the congenital cases, 128 cases were acyanotic and 26 cases were cyanotic. Among the 57 cases of acquired valvular replacement surgery, 3 cases had open heart commissurotomy, one had Kay annuloplasty. 2.The age distribution of the congenital acyanotic anomalies ranged from 5 to 32 years with mean age of 12.8 years, the congenital cyanotic anomalies from 3 to 29 years with mean age of 14.2 years and the acquired valvular diseases from 9 to 51 years with mean age of 30 years. The difference of sex distribution was no significance. 3.Three methods for debubbling process were used in our institute, in 133 cases, the vent was inserted into the left ventricular apex, in 61 cases inserted into the left atrium through right superior pulmonary vein and in 17 cases used needle aspiration only. 4.For cardioplegia, the GIK solution was infused repeatedly from 30 to 40 minutes interval and brought excellent results for myocardial protection during open heart surgery. 5.Overall mortality was 7.6%. The mortality along with each disease is 1.56% in congenital acyanotic cases, 26.9% in congenital cyanotic cases and 12.3% in acquired valvular disease.

Over a period from May, 1977 to SEptember, 1982, 101 cases ofopen heart surgerywere done under cardiopulmonary bypass. There were 50 male and 51 female patients, and the ages of the patients ranged from 19 months to 48 years. Sixty-nine cases were congenital heart disease and 32 cases were acquired heart disease, which consisted of 30 valvular disease, 1 IVC obstruction, and 1 myxoma. Among the 30 cases of valvular disease, 12 MVR, 4 MVR+TAP, 2 MVT+AVR, 1 MAP, and 11 OMC were done. There were 3 operative deaths (17.5%) in 16 MVR, 1 in 2 MVR+AVR, and 1 in 11 OMC. Operative mortality in 69 congenital heart disease was 13.0% ; 3 deaths (6.7%) in 45 acyanotic and 6(25.0%) in 24 cyanotic cases. The overall mortality for 101 cases was 14.8%; 13.0% for congenital and 18.8% for acquired heart disease.

From May 1977 to April 1984, 204 cases of open heart surgery were performed under cardiopulmonary bypass. There were 99 male and 105 female patients ranging in age from 19 months to 58 years. 136 cases [66.7%] were congenital heart disease, and 68 cases [33.3%] were acquired heart disease, which were 66 valvular disease [97.1%], 1 IVC obstruction, and 1 myxoma. There were 136 congenital heart anomaly with 16 operative deaths [11.8%], consisting of 94 acyanotic cases with 7 death [7.4%] and 42 cases of cyanotic cases with 9 deaths [21.4%]. In 66 patients of acquired valvular disease, 52 valves were implanted; 47 mitral valve replacement with 4 death [8.5%] and 5 double valve replacement [MVR+AVR] with 1 death [20%]. Postoperative, warfarin sodium was medicated with checking prothrombin time. Finally, the operative mortality was 11.8% in congenital anomaly, and 11.8% in acquired heart disease, overall mortality rate was 8.5%.

Over a period from July 1984 to June 1985, 39 cases of open heart surgery were done under cardiopulmonary bypass. There were 23 male and 16 female patients, ranging in age from 18 months to 58 years. Thirty cases were valvular disease. The most common of congenital heart disease is VSD. Among the 9 cases of acquired valvular diseae,1 MAP, 5 MVR, 2 MVR+TAP, and 1 MVR+AVR were done. There were 1 operative death[11%] which was done MVR+TAP. Operative mortality in 30 congenital heart disease was 7%; 1 death [5%] in 22 acyanotic and 1[13%] in 8 cyanotic cases. Finally, overall mortality for 39 cases was 8%; 7% for congenital heart disease and 11% for acquired heart disease.

From May 1977 to November 1993, 1, 500 cases of open heart surgery were performed under the cardiopulmonary bypass. In 1500 cases of open heart surgery 975 cases[65%] were congenital heart disease and 525 cases[35%] were acquired heart disease. In 975 cases of congenital heart disease, there were 812 cases[83%] of acyanotic congenital heart anomaly and 163 cases of cyanotic congenital anomaly. In 525 cases of acquired heart disease, most cases were valvular heart disease in which 557 valves were implanted. The each operative mortality of congenital and acquired disease was 7.7% and 7.4% respectively and then overall mortality rate was 7.6%. There has been increasing incidence of open heart surgery in infants in recent years. After 1990, 28 cases of infant open heart surgery below the 12month were performed. Most lowest weight was 2, 200g[15 days]. Operative mortality of open heart surgery in infant with weight below the 10kg was very high as a 25.7%.

Congenital coronary arteriovenous fistula is a rare cardiac defect that causes coronary arterial flow to drain into the right cardiac chambers, the pulmonary artery, the coronary sinus, or the left cardiac chambers. The most frequently involved vessel is the right coronary artery. We experienced a case that had a coronary arteriovenous fistula associated with valvular heart disease. With the cardiopulmonary bypass done under hypothermia, mitral valve replacement was accomplished and the fistulas of both proximal and distal portions of the right coronary artery were closed with 3-0 prolene. Postoperative course was uneventful.

One hundred eleven cases of open heart surgery had been performed at the department of thoracic and cardiovascular surgery in College of Medicine Hallym Univ. from November 28, 1984 to August, 1991. There were 68 cases of congenital heart disease and 43 cases of acquired heart disease. Among the 68 cases of congenital heart diseases, 65 cases of acyanotic group and 3 cases of cyanotic group were noted. The majority of acquired heart diseases were valvular heart disease. The congenital heart disease consisted of 33 ASD, 27 VSD, 6 PS, 3 TOF. The sex ratio of congenital and acquired heart diseases was represented as 1.4: 1 and 1; 1.4 respectively. The age distribution of congenital heart diseases ranged from 11 months to 50 years old and that of acquired heart diseases from 15 to 61 years old. The overall operation mortality was 1 case[0.9%].
