From October 1989 to 1991 May, 100 cases of open heart surgery were performed under the cardiopulmonary bypass. 1. There were 47 male and 53 female patients ranging in age from 2 months to 64 years. 2. Of 100 cases of open heart surgery, 65 cases were congenital heart diseases, and 35 cases were acquired heart diseases. 3. In 65 cases of congenital heart diseases, there were 60 cases[92 %] with acyanotic heart anomaly and 5 cases [8 %] with cyanotic heart anomaly. 4. Among the 42 patients less than 15 years of age, 21 patients[50%] were below 10 kg and the operative mortality was 0.05 %. 5. The overall mortality was 4 %, and the operative mortality of congenital and acquired heart disease was 3.1% and 5.6%.

A 7-month-old girl with no medical history was treated with mechanical circulatory support due to myocarditis. Her cardiac contractility did not improve despite more than one week of extracorporeal membrane oxygenation treatment. Thus, we planned a heart transplant. However, a high level of cytomegalovirus was found in blood laboratory results by quantitative polymerase chain reaction. The patient's heart contractility recovered to normal range four days after ganciclovir treatment. She was discharged with slightly decreased cardiac contractility with a left ventricular ejection fraction of 45%.

A 4-month-old boy diagnosed with acute myocarditis was treated with extracorporeal membrane oxygenation (ECMO). Follow-up echocardiography eight hours after ECMO revealed intracardiac thrombosis involving all four heart chambers. Because of the high risk of systemic embolization due to a pedunculated thrombus of the aortic valve, we performed an emergency thrombectomy. After the operation, the patient had a minor neurologic sequela of left upper arm hypertonia, which had almost disappeared at the last outpatient clinic two months later. He was diagnosed with a major mutation in MTHFR (methylenetetrahydrofolate reductase), which is related to thrombosis.

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%].

From May 1977 to April 1990, 1000 cases of open heart surgery were performed under the cardiopulmonary bypass. There were divided into group A[500 cases, from May 1977 to June 23rd 1986] and group B[500 cases, from June 23rd 1986 to April 1990] which were analyzed, summarized, and compared. Of 1000 cases of open heart surgery, 677 cases[67.7%] were congenital heart diseases, and 323 cases[32.3%] were acquired heart diseases. In 677 cases of congenital heart disease, there were 545 cases with acyanotic congenital heart anomaly[A: 279, B: 266] and 132 cases with cyanotic congenital heart anomaly[A: 87, B: 45]. In 323 cases of acquired heart disease, most cases were valvular heart disease[315 cases, A: 133, B: 182] in which 357 valves were implanted. The operative mortality of congenital R acquired heart disease was 7.8% & 8.0%, and then overall mortality was 7.9%. The operative mortality was markedly decreased. [about half] from 10.0% of A group to 5.6% of B group.

Interpostion arthroplasty with allograft has been known as a useful option for the shoulder arthropathy, but it has a limitation to immune response. We performed the pectoralis major muscle transfer for shoulder arthropathy. From January 2007 to December 2007, we performed the pectoralis major muscle transfer in 2 patients. They were 1 man and 1 woman, and the mean age of the patients was 70 years (range, 65 to 75). The average follow-up after surgery was 13 months (range, 12 to 14). We analyzed the clinical results by the American Shoulder and Elbow Surgeons (ASES) Score, and evaluated the pain by Visual Analogue Scale. The level of pain reduced from a preoperative average of 10 to a postoperative average of 1. The ASES scores increased from a preoperative mean of 9 to a postoperative mean of 58. These results indicated that interposition arthroplasty with the pectoralis major muscle transfer is a reliable treatment method for the shoulder arthropathy improving shoulder pain, and patient satisfaction.

During a 4 year period from 1987 to 1991, 152 patients underwent open heart surgery for congenital heart disease and acquired heart disease. Over all operative mortality was 6.6%. There were 76 congenital anomalies consisting of 73 acyanotic and 3 cyanotic and 76 acquired heart disease. The age distribution of 152 cases was 3 months to 62 years. Mean age was 13.0 years in congenital heart anomalies and 38.9 years in acquired heart disease patients.

A coronary artery fistula was surgically ligated in a 38-year-old woman via a left anterior mini-thoracotomy without the use of cardiopulmonary bypass. In selected cases, this surgical approach can provide an excellent surgical exposure for coronary artery fistula ligation. It also offers an excellent cosmetic result and shorter hospital stay.

Patients with venoarterial extracorporeal membrane oxygenation (ECMO) frequently suffer from pulmonary edema due to left ventricular dysfunction that accompanies left heart dilatation, which is caused by left atrial hypertension. The problem can be resolved by left atrium (LA) decompression. We performed a successful percutaneous LA decompression with an atrial septostomy and placement of an LA venting cannula in a 38-month-old child treated with venoarterial ECMO for acute myocarditis.
