Last year in this department 100 cases of open heart surgery were done annually. This year 200 cases of open heart surgery were scheduled. During the first 6 months of this year 112 open heart surgery cases were done with 13 deaths [11.6%]. There were 72 cases of cougenital malformation with 9 operative deaths [12.5%], consisting of 23 acyanotic cases with one death [4.5%] and 49 cases of cyanotic cases with 8 deaths [16.3%]. Out of 40 tetralogy of Fallot, 6 cases expired [15%]. For 39 cases of acquired valvular heart disease and one Ebstein anomaly valves were replaced with 4 operative deaths [10%]. Single valve replacement in 33 with 3 operative deaths and double valve replacement in 7 cases with one death were noted. Two patients expired among 28 mitral valve replacement cases [7.1%]. Among 7 double valve replacement patients, consisting of 3 mitral and aortic and 4 mitral and tricuspid valve replacement one case expired. In a case of Ebstein anomaly, tricuspid valve was replaced with plication of atrialized right ventricle successfully. The operative result was excellent.

One hundred cases of cardiac valve replacement were done at this Department in the period from June 1968 to May 15, 1978. Seventy-one cases of mitral, 12 aortic, and one tricuspd valve were replaced. There were 16 cases of double valve replacement, 10 aortic with mitral and 6 mitral with tricuspid valve replacement. Prosthetic valves-Beall, Bjoerk-Shiley, Starr-Edwards, Wada-Cutter, Magovern-Cromie, and Smeloff-Cutter valves-were used. But in recent years bioprosthetic valves-Hancock, Carpentier-Edwards, and Angell-Shiley valves-were used mainly due to the difficulties of postoperative anticoagulation, especially for the rural Korean patients. Over all operative mortality was 2896, 26.2% for single and 37.5% for double valve replacement cases. There were 4 postoperative thrombo-embolism cases with 2 deaths. Four postoperative subacute bacterial endocardities cases with 2 deaths were noted. Three cases of postoperative congestive heart failure succumbed. Two cases of peri valvular leakage, one of which needs reopration, were found. There were 28 operative and 9 late deaths, leaving 63 long-tel m survivors, who showed marked improvements.

Background: Mitral regurgitation is one of the leading causes of cardiovascular morbidity in pediatric patients with Marfan syndrome. The purpose of this study was to contribute to determining the appropriate surgical strategy for these patients. Methods: From January 1992 to May 2013, six patients with Marfan syndrome underwent surgery for mitral regurgitation in infancy or early childhood. Results: The median age at the time of surgery was 47 months (range, 3 to 140 months) and the median follow-up period was 3.6 years (range, 1.3 to 15.5 years). Mitral valve repair was performed in two patients and four patients underwent mitral valve replacement with a mechanical prosthesis. There was one reoperation requiring valve replacement for aggravated mitral regurgitation two months after repair. The four patients who underwent mitral valve replacement did not experience any complications related to the prosthetic valve. One late death occurred due to progressive emphysema and tricuspid regurgitation. Conclusion: Although repair can be an option for some patients, it may not be durable in infantile-onset Marfan syndrome patients who require surgical management during infancy or childhood. Mitral valve replacement is a feasible treatment option for these patients.

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.

Objectives: The purpose of this study was to evaluate the effects of shenfu injection on myocardial protective effects after mitral valve replacement surgery. Methods: We searched four international databases (PUBMED, Embase, Web of Science and CNKI) and three domestic electronic databases (OASIS, RISS and NDSL) for relevant studies. We used following keywords 'shenfu', 'valve replacement', 'mitral valve' at PUBMED, Embase and Web of Science; '二尖瓣', '参附注射液', '瓣膜' at CNKI and '이첨판', '판막', '삼부' at domestic databases. The search range included randomized controlled trials. When appropriate, meta-analyses were performed. Results: Seven randomized controlled trials were selected. All studies used Shenfu injection after mitral valve replacement surgery. We analyzed myocardial damage, cardiac function, patients' recovery rate, with various evaluation indicators. We also used meta-analysis for CK-MB, cTnI, MDA and voluntary recovery of heartbeat. CK-MB was analyzed in two subgroups: 8 hours and 24 hours after surgery. Std was -2.34(95% CI -4.10, -0.58) for 8 hours and -1.95(95% CI -4.79 to 0.88) for 24 hours. 8 hours showed statistically significant difference. cTnI appeared significant decrease with Std of -2.13(95% CI -2.60, -1.66). MDA showed significant decrease with Std of -0.95(95% CI -1.43 to -0.47). Voluntary recovery of heartbeat significantly increased with the odd ratio of 4.34(95% CI 1.76, 10.70). Conclusions: We suggest that Shenfu injection after Mitral valve replacement surgery may have significant myocardial protective effects in terms of reducing myocardial damages, reactive oxygen species, increasing cardiac function and patients' recovery after surgery. However, the evidence is limited, further research is required.

From June 1984 to February 1994, cardiac valve replacement was performed in 108 patients. The distribution of patients was ranged from 13 to 64 year-old age[mean 39.48 1.24] and 51 patients were male, 57 patients were female [male:female=1:1.1]. 64 patients had mitral valve replacement, 27 patients underwent aortic valve replacement and 17 patients were performed double[mitral & aortic] valve replacement. Total 125 artificial cardiac valves were used, mechanical valves were 51 valves and tissue valves were 74 valves. The duration of follow-up was 473.41 patient-year[mean 4.79 3.29 patient-year] and the information of follow-up was available for 99 patients[92%]. The actuarial survival rates including the operative mortality was 89.5% & 88.3 at postoperative fourth & ninth year. The probability of freedom from overall valve failure, thromboembolism and bacterial endocarditis were 77.5%, 89.2% and 95.6% at ninth year after cardiac valve replacement.
