We had studied 20 cases of VSD patients whose murmur was sustained after open heart surgery from 1977 to 1984. The postoperative cardiac catheterization was performed on post-op. 20th day. Their ages ranged from 5 to 25 years old. Among them, 4 patients had significant residual shunt which required reoperation. [1 patient; re-op, 3 patient; refused]. Sex ratio was 13:7 in male and female. Associated anomalies were PDA, ASD, Pulmonary stenosis, Mitral insufficiency. Except 1 case, all of them was Kirklin type II VSD. Postoperative complications were I RBBB, residual shunt, cardiac tamponade due to bleeding, wound infection. Preoperative pulmonary artery systolic pressure was highly related to residual shunt in our study. Postoperative LVEDV returned to normal range on the 3rd week.

Fifty seven patients underwent repair of a partial atrioventricular septal defect from January 1980 to December 1986. The ostium primum atrial septal defect was closed with autologous or bovine pericardium. The cleft in the anterior mitral leaflet was present in 53 cases, absent in 4 cases. Of the 53 cases with a cleft in the anterior mitral leaflet, 48 received suture repair of the cleft, 3 received mitral valve replacement. There was no hospital death and all the patients were followed-up for a mean period of 26.4 months. Four required permanent pacemaker implantation due to complete heart block, and one of them died of sudden malfunction of pacemaker. Two received reoperation due to significant residual mitral insufficiency. Suture repair of the cleft in the anterior mitral leaflet resulted in significant decrease in degree of mitral regurgitation. During follow-up period 49 patients were in NYHA class I, 7 patients were in NYHA class II. This report suggests that excellent result can be achieved from repair of the partial atrioventricular septal defect by managing the left A-V valve as a bileaflet structure.

Between 1977 and 1987, 8 patients underwent excision of cardiac myxomas at the Hanyang University Hospital. All had a left atrial myxoma. There were 4 female and 4 male patients ranging from 15 to 62 years of age. Preoperative findings consist of symptoms and signs of congestive heart failure except one. Diagnosis was confirmed by echocardiography[8 cases] and angiography[2 cases], preoperatively. A biatrial operative approach was utilized in all but 2, who were small sized. Complete excision of the tumor with a cuff of normal tissue[1 was atrial wall and 7 were atrial septum] was performed. all heart chambers were carefully explored for presence of multicentric myxomas or tumor debris. There were no operative deaths or intraoperative embolization. Follow-up has been 1/3 to 10 years. There has been 1 late death, due to recurrence and 1 patient had reoperation for mitral regurgitation due to dilatation of the annulus by a huge tumor mass. Surgical excision of the myxoma can be performed with low morbidity, and it provides excellent and sustained symptomatic relief. The recurrence rate is low, but long-term follow-up and serial echocardiography are advisable.

The comprehensive aortic root and valve reconstruction (CARVAR) technique comprises two main procedures, which are aortic root reduction using prosthetic rings and neo-leaflet reconstruction using a pericardial patch. Although concerns about durability of the pericardial neo-leaflet have been raised in the CARVAR technique, complications related to leaflet reconstruction have not been reported to date. The present report describes two cases of complications associated with leaflet reconstruction. After resecting the reconstructed leaflets, aortic valve replacement was performed in the patients. Careful and close follow-up is required for patients who had undergone CARVAR surgery, and aortic valve surgery should be performed in a timely manner if needed.

We experienced eleven cases of pulmonary aspergllosis treated surgically in the period from 1981 to 1992. There were 5 men and 6 women, ranging in age from 28 to 64 years [mean age 40.4 years]. The most common chief complaint of the patients was hemoptysis and blood tinged sputum[7 cases, 63.6%], On preoperativechest film, the case of cavity with fungus ball[7 cases] and only cavity[4 cases] were seen. The location of the lesion were both upper lobe[6 cases] and lower lobe[5 cases]. The underlying disease were tuberculosis[5 cases], bronchiectasis[2 cases], tuberculosis and bronchiectasis[1 case], pneumonia[1 case] and none[2 cases]. The operative procedures of pulmonary aspergillosis were lobectomy[8 cases], cavernostomy[1 case] and thoracoplasty[2 cases]. The postoperative complications were postoperative massive bleeding[reoperation, 2 cases], wound infection[2 cases] and no operative mortality.

During 6 year period from January, 1987 through December, 1992, a total of 17 valvular reoperations [14 mitral and 3 aortic valve reoperations] were performed in 15 patients with previously implanted prosthetic valves. There were 7 men and 8 women, mean age was 35.4 years. Mean time interval was 80 months. Causes for reoperations were prosthetic valve failure, prosthetic valve endocarditis, and periprosthetic leak.3 patients died in hospital. The cause of death were low cardiac output and acute renal failure.

Forty-five patients with double-outlet right ventricle[DORV] underwent complete intracardiac repair between July, 1983 and June, 1989. Patients with complete atrioventricular canal, atrioventricular discordance and uni-ventricular heart were excluded. The 32 male and 13 female patients ranged in age from 3 months to 15 years[mean 4 years]. Thirty-two patients had pulmonary stenosis. The early mortality was 11.ltd[5 /45] None of 27 died after a completely intraventricular repair. The mortality was 20%[1/5] for repair using transannular patch, 20% [1/5] for REV operation, 33.3%[1/3] for repair including extracardiac valved conduit, and 50% [1/2] for Jatene operation, respectively. Two modified Fontan procedures were performed without mortality. One died after Senning operation. Causes of early deaths included high residual right ventricular pressure[one patient] small left atrial and left ventricular volume[one patient], persisting severe pulmonary hypertension [one patient] and low cardiac output of unknown cause [two patients]. Complete heart block developed in one patient. Two late deaths occurred among the 40 operative survivors [5.0Po] from persisting severe pulmonary hypertension and bleeding at reoperation. Our results indicate that significant defects can be repaired with low mortality and morbidity.

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.

A 73-year-old woman who underwent combined bioprosthetic mitral valve replacement, tricuspid ring annuloplasty, and coronary artery bypass grafting 12 years previously visited our clinic due to aggravated dyspnea caused by structural valve deterioration of the mitral prosthesis. Because aortic or femoral artery cannulation and cross-clamping would have a high risk of stroke owing to severe calcification of the ascending aorta and ilio-femoral vessels, and because there was a risk of redo sternotomy due to the patent bypass grafts, a comprehensive approach including axillary artery cannulation, a minimally invasive right thoracotomy approach, and a clampless hypothermic fibrillatory arrest technique was used during redo mitral valve replacement.

We reviewed literatures of western and oriental medicine about postoperative management of spine. Traditionally, with orthoses and bed rest, many physicians restricted activity of daily life and back exercises of patients who had taken spine surgery. More aggressive early mobilization, however, such as strengthening exercise and stretching after 4 weeks of surgery gets grounds nowadays. Physical therapies including manipulation, TENS, MENS, ultrasound and cryotherapy are being used as helpful treatment modalities of postoperative pain and swelling. Failed back surgery syndrome occurs due to wrong patient, diagnosis and surgery and is managed with conservative treatment or reoperation. In oriental medicine, treatments of musculoskeletal injuries including surgical wound are based on the balance of chi(氣) and blood(血).
