Result of St. Jude Medical valve replacement are presented in 106 patients who underwent operation from January 1985 through July 1989. The patient were 52 males and 56 females. Total 136 of St. Jude Medical valves were implanted; 91 in mitral position, 45 in aortic position. The hospital mortality rate was 5.7%o[6 patients] and the late mortality rate was 2.0%[2 patients]. The causes of death were low cardiac output in 5, iatrogenic right ventricular rupture in 1, heart failure in 1, ventricular arrhythmia in l. And, the causes of valve related complication were anticoagulant related hemorrhage in 5 patients[0.03% /patient-year] and thromboembolism[0.01% /patient-year] in 2 patients. In conclusion, the performance of the St. Jude Medical valve compare most favorably with other artificial valves. But it remains still hazards of mechanical prosthesis such as thromboembolism and anticoagulant related hemorrhage.

Charcot spine is a progressive and destructive process that affects the vertebral bodies, intervertebral discs, and posterior facets. It is the result from repetitive microtrauma in patients who have decreased joint protective mechanisms due to loss of deep pain and proprioceptive sensation, typically because of spinal cord injury. The objective of the study is to report an unusual case of Charcot spine, as a late complication of traumatic spinal cord injury, treated by a circumferential arthrodesis performed with a single staged posterolateral costotransversectomy approach.

The consecutive 35 patients underwent isolated aortic valve replacement with the low-profile model of the Ionescu-Shiley pericardial xenograft valve from 1984 to 1991. Operative mortality was 2.9%, and early survivors were followed up for a total 136.1 patient-years[Mean$\pm$SD, 4.00$\pm$2.14 years]. The linearized late mortality was 2.204% /pt-yr. Three patients required rereplacement of the valve with overall valve failure rate of 2.204% /pt-yr: two for endocarditis and one for paravalvular leak. There was no case of primary tissue failure. The linearized annual rates of complication were: thromboembolism 0.735% /pt-yr, bleeding 0.735%pt-yr, and endocarditis 2.204% /pt-yr. The actuarial survival at 8 years of follow-up was 90.4$\pm$5.3%, and the probabilities of freedom from thromboembolism and from rereplacement were 95.6$\pm$4.4% and 88.2$\pm$6.7% at 8 years respectively. Although the low profile Ionescu-Shiley pericardial valve provided favorable clinical performance comparable with the standard model up to 8 years, it needs prolonged follow-up to assess the pattern of its durability.

Approximately 10% of patients who have undergone atrial repair for transposition of the great arteries display easily identifiable RV dysfunction with or without TV incompetence by 10years. Treatment is difficult & the surgical options for this complication are limited. We experienced two cases of the reversal of atrial repair and conversion to an arterial switch after initial pulmonary artery banding. This surgical program is a realistic modality treating late failure of systemic right ventricle after atrial switch operation.

Transradial access is a widely accepted method for percutaneous coronary diagnostic and interventional procedures, and it has dramatically reduced access site vascular complications compared to transfemoral access. Arteriovenous fistula formation at the access site is an especially rare complication in transradial access. We report an extremely rare case of delayed radial arteriovenous fistula that developed one year after transradial coronary angiography, which was successfully treated by surgical repair.

Between January 1984 and January 1994, 13 patients developed mediastinitis after cardiac operations. There were 7 women and 6 men with a mean age of 24.2 years[range 0.7 - 61 . Initial operation included 7 valve replacements and 6 congenital cardiac repairs. The duration between initial operation and diagnosis was 13.5 days[range 4-57 . Organisms cultured from debridement material included S.aurus[n=9 , S.epidermidis[n=3 and Enterobacter[n=1 . Fever was the most frequent complaint and purulent drainage was noticed in 9 patients[69% . Seven patients were treated with radical debridement followed by closed irrigation. In other 6 patients, the wounds were managed by debridement, open granulation and delayed wound closure. Two hospital deaths [15.4% following open granulation method, resulted from sepsis. The 11 survivors were followed-up for 1-120 months, averaging 42 months and had healed wounds. One late death occurred due to massive hemorrhage.

From June, 15th, 1987 to June, 14th, 1989, 105 Duromedics bileaflet cardiac valve prostheses were implanted in 81 patients. Mitral valve replacement was done in 42 patients, 7 underwent aortic valve replacement, 28 underwent double valve replacement, & 4 patients underwent triple valve replacement. Concomitantly used valves were 13 cases; 11 cases were St. Jude Medical valves[M: SJM #29 X4, #27 X5, #25 X 1, T: SJM #33] & two cases were Carpentier Edwards bioprostheses[T: C - E #31X2]. The early mortality rate[within 30 days] was 3.7%[2 patients] & the late mortality rate was 7.4%[3 patients]. Follow-up was done on 72 surviving patients; mean follow-up period was 21.17$\pm$5.36 months. Anticoagulant-related hemorrhage was observed in two patients, possible prosthetic valvular endocarditis was observed in one patient and other specific valve-related complications were none. We concluded, therefore, that good clinical results & a low complication rate could be achieved with Duromedics bileaflet valve in short-term follow-up, & long-term follow-up was also necessary.

One hundred and fourty-one Bjork-Shiley Monostrut valves were implanted in 105 consecutive patients from November 1983 to February 1990. There were 61 male and 44 female patients with a mean age of 33.6 years at the surgery. The cummurative follow-up was 370.3 patient-years with a mean of 44.0 months per patient. The operative mortality rate was 3.8%, and the linealized late mortality was 1.18%/patient-year. The incidence of major complications were 4.59%/patient-year, and the actuarial rate of freedom from valve-related morbidity was 80.2$\pm$4.4% at 7 years. The 7-year survival rate was 90.5$\pm$4.1%, and the actuarial rate of freedom from thromboembolism at 7 years was 93.3$\pm$2.3%. The linealized annual rates of complication were ; structural valve failure 0.27% /patient-year, non-structural valve failure 0.54% /patient-year, thromboembolism 1.62% /patient-year; bleeding 1.62% /patient-year; endocarditis 0.54% /patient-year. On the basis of our experience, we judged the Bjork-Shiley Monostrut valve reliable, with similar incidence of valve-related morbidity of other mechanical prosthetic valves.

Pulmonic autograft replacement of the aortic valve(Ross procedure) has been to have potential for growth in children, no complication of antiocagulation, and enhanced durability. Therefore, Ross operation is indicated in the young, in patients with an active life style, and when anticoagulation is contraindicated. However, late autograft valve has occurrd more frequently in patients with significant size discrepancy between the pulmonay valve annulus and the aortic valve annulus. In order to resolve this problem, we performed aortic annuloplasty with Duran ring for more accurate and strong reinforcement. We report a case using the Duran ring as a method of aortic annuloplasty during Ross procedure.

Postpneumonectomy syndrome (PPS) is a rare late complication of pneumonectomy. It occurs more often in children than in adults, and is characterized by respiratory failure resulting from bronchial compression caused by severe mediastinal shift. Various methods have been used to treat PPS, including aortopexy and the insertion of plastic balls, silastic implants, and saline-filled breast prostheses. We describe two cases of PPS corrected with tissue expanders after right pneumonectomy in patients with esophageal atresia.
