Between Feb. 1990 Aug. 1993, 180 cases of the open heart surgery were performed under cardiopulmonary bypass in the Department of Thoracic & Cardiovascular surgery, Gill General Hospital.
There were 83 cases with congenital heart diseases(CHD) and 97 cases with acquired heart diseases (AHD). The CHD consisted of 78 acyanotic(mortality: 3.8%) and 5 cyanotic cases with heart anomaly(mortality:1 case). The AHD were 97 cases, which
contained
53 valvular, 27 ischemic heart diseases, 10 aortic diseases, 5 cases with myxoma, 1 case with post-infarct VSD, and 1 case with removal of infected pacing wire in right ventricle.
In the 53 valvular heart diseases, there were 45 cases with valve replacement(MVR 27, AVR 9, MVR+AVR 9) and 8 cases with valvuloplasty. The number of the implanted prosthetic valves were 53. In MVR, 25 St. Jude, 6 Sorin, 3 Carpentier-Edward and 2
Intact
medical valves were used. In aortic position, 13 St. Jude, 3 Sorin and 1 Intact medical valves were applied. The operative mortality was 5.6%(3/53).
The annuloplasty applying artificial ring was performed in 17 patients(4 cases associated with MVR) and the number of the implanted ring was 19, which included 14 Duran ring(10 mitral, 4 tricuspid) and 5 Carpentier ring(3 mitral, 2 tricuspid).
In the 27 ischemic heart diseases, there were 9 cases with left main coronary artery lesions, 7 one vessel, 5 two vessels, and 8 three vessels. Average number of anastomosis was 2.8 per patient. The operative mortality was 14.3%(4/27).
Among the 10 patients with aortic diseases, 7 cases were aortic dissection(type A: 5, type B:2) and 3 cases were descending thoracic aortic aneurysm, The operative motality occurred in 3 cases.
The overall mortality and the operative mortality of congenital and acquired heart disease was 7.8%, 4.8%, and 10.4%, respectively. (Korean J Thoracic Cardiovas Surg 1994; 27:460-71)
