Sixteen cases of cardiac valve replacements have been done in this department since 1970. Twelve cases of mitral valve replacement were done with Beall valve, 2 cases of aortic valve replacement with Starr-Edwards and Magoven valve and 2 cases of double valve replacement using Beall valve for mitral and Magovern valve for aortic. Three patients [18.8%] died during operation. Two cases [12.5%] of hospital mortality occurred because of congestive heart failure and asphyxia due to tracheomalacia 3 months after operation. Follow-up studies from two to 27 months showed excellent results except three cases of late mortality [18.8 %]. Thromboembolism occurred in two double valve replacement patients[12.5%]who were fatal.

Anticoagulation therapy is essential after cardiac valve surgery. However, spontaneous bleeding remains a major concern during anticoagulation therapy. Spontaneous gallbladder (GB) hemorrhage (hemobilia) is a rare occurrence during standard anticoagulation therapy. This report presents a case of GB hemorrhage that occurred shortly after initiating oral anticoagulant therapy in a patient who had undergone mitral valve replacement surgery.

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.

Between Jan. 1978, and Dec. 1983, a total and consecutive 117 patients have undergone cardiac valve replacement using various artificial tissue valve. Out of 117 patients, single valve surgery was 78 consisted of MVR 74, AVR 3 and AVR & supracoronary ascending aorta replacement 1. Multiple valve surgery was 39 cases consisted of MVR+TAP 20, MVR+AVR 13 and so on. Early death with 30 days after operation was 12 cases [early mortality 10.3%] and causes of death were cardiac origin 5, technical problem 4, and others 3. The 105 early survivors were followed-up for a total of 190.5 years over a period of 2 to 64 months [Mean\ulcornerD:21.9\ulcorner4.9 months]. During follow-up, 7 cases died [late mortality:6.7%]. The rate of thromboembolism was 2.1% episodes per patient-year and bleeding due to anticoagulant was 3.1% episodes per patient-year and valve failure was 1.6% episodes per patient-year. Actuarial analysis of late results indicated an expected survival rate at 5 years of 84.6% for patients with single valve surgery and 82.1% for patient with multiple valve surgery and overall was 83.8%. Symptomatically, 86.7% of patients were in NYHA class I or II at the end of follow-up.

Background: Achieving external access to and manual occlusion of the left atrial appendage (LAA) during minimally invasive mitral valve surgery (MIMVS) through a small right thoracotomy is difficult. Occlusion of the LAA using an epicardial closure device seems quite useful compared to other surgical techniques. Methods: Fourteen patients with atrial fibrillation underwent MIMVS with concomitant surgical occlusion of the LAA using double-layered endocardial closure stitches (n=6, endocardial suture group) or the AtriClip Pro closure device (n=8, AtriClip group) at our institution. The primary safety endpoint was any device-related adverse event, and the primary efficacy endpoint was successful complete occlusion of blood flow into the LAA as assessed by transthoracic echocardiography at hospital discharge. The primary efficacy endpoint for stroke reduction was the occurrence of ischemic or hemorrhagic neurologic events. Results: All patients underwent LAA occlusion as scheduled. The cardiopulmonary bypass and aortic cross-clamp times in the endocardial suture group and the AtriClip group were 202±39 and 128±41 minutes, and 213±53 and 136±44 minutes, respectively (p=0.68, p=0.73). No patients in either group experienced any device-related serious adverse events, incomplete LAA occlusion, early postoperative stroke, or neurologic complication. Conclusion: Epicardial LAA occlusion using the AtriClip Pro during MIMVS in patients with mitral valve disease and atrial fibrillation is a simple, safe, and effective adjunctive procedure.

Recently, we have experienced a case of acute thrombotic obstruction of the St. Jude Medical cardiac valve in the mitral position of the Heart. We will discuss about the incidence, recognition and preventive measurement of the thrombotic St. Jude Medical valve with the review of literatures.

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.

51세 환자가 3개월 전에 심장 자상으로 본원에 입원하여 심장봉합수술을 받았다. 이후 별다른 소견 없이 지내다가 약 2개월 전부터 발생된 호흡곤란을 주소로 내원하였다. 심장초음파상 심한 삼첨판막 페쇄부전이 관찰되었으며 삼첨판막의 건삭치환술과 판윤 성형술을 실시하였다. 이에 저자들은 심장 자상 후에 발생된 삼첨판막 폐쇄부전을 판막성형술로 치료하였기에 증례보고를 하는 바이다.

Between April 9, 1986 and September 2, 1987, 134 patients underwent open heart surgery with hypothermic cardiopulmonary bypass and cold blood cardioplegia. There were 65 patients[48.5%] of acyanotic congenital cardiac anomalies, 19 patients[14.2%] of cyanotic congenital cardiac anomalies, and 50 patients[37.3%] of acquired heart diseases, which included 49 valvular diseases and 1 myxoma. In 84 congenital cardiac anomalies, 44 patients were male and 40 patients were female ranged in age from 2 years to 57 years. In 50 acquired heart diseases, 18 patients were male and 32 patients were female ranged in age from 10 years to 65 years. The common congenital defects operated were VSD in acyanotic cardiac patients, and Tetralogy of Fallot in cyanotic cardiac patients. Among 50 acquired heart diseases, 49 patient underwent operation for cardiac valvular lesions. 33 patients had mitral valve replacement and 7 patients had aortic valve replacement. 1 patient underwent aortic valvuloplasty and 8 patients had double valve replacement. The operative mortality rate was 3.1%[2 out of 65 patients] in acyanotic cardiac patients, 5.3%[1 out of 17 patients] in cyanotic cardiac patients, and 12.0%[6 out of 50 patients] in acquired cardiac patients, with overall mortality rate of 6.7%[9 out of 134 patients].
