As higher mortality rate and frequent incidence of morbidity, early surgical treatment is generally recommended for the multivalvular endocarditis. A 46-year-old female presented with high fever. Echocardiography showed the vegetation on pulmonic valve, tricuspid valve and mitral valve with a ventricular septal defect. Emergency operation was conducted due to uncontrolled infection. We present a clinical success of this rare case with review of the medical literature.

Between September 1986, and August 1989, eight infants underwent operation for repair of coarctation of the aorta in the first year of life. The patients included 7 males and 1 female ranging in age 19 days and 9 months. Weights ranged from 3.5 Kg to 7 Kg [mean 5 Kg]. All patients had preductal coarctation of the aorta. Each infant had associated cardiac anomalies, including ventricular septal defect [7 infants] and patent ductus arteriosus [5 infants]. All had intractable congestive heart failure, despite aggressive medical therapy. Pressure gradient across the coarctation ranged from 10 mmHg to 60 mmHg. Operative techniques were subclavian flap aortoplasty in five cases, Gore-Tex patch aortoplasty in three cases. In addition to coarctation repair, six infants had concomitant banding of the pulmonary artery. Four infants required ventilator support for several days. There was no operative death. Complications developed in two. One infant had tracheal stenosis after a tracheostomy. Another infant had restenosis of the aorta revealed by cardiac catheterization 30 months after surgery. The pressure gradient was 30 mmHg, necessitating balloon dilatation aortoplasty. Results were satisfactory. During follow up, we performed total correction procedures [patch closure of the ventricular septal defect, infundibulectomy, pulmonary valvotomy and pulmonary artery angioplasty] in one case. Continuing follow-up finds all patients in good condition.

Background: Surgical repair of post-infarct ventricular septal defect (VSD) is considered one of the most challenging procedures having high surgical mortality. This study aimed to evaluate the outcomes of the surgical repair of post-infarct VSD. Methods: From May 1991 to July 2012, 34 patients (mean age, $67.1{\pm}7.9$ years) underwent surgical repair of post-infarct VSD. A retrospective review of clinical and surgical data was performed. Results: VSD repair involved the infarct exclusion technique using a patch in all patients. For coronary revascularization, 12 patients (35.3%) underwent concomitant coronary artery bypass graft, 3 patients (8.8%) underwent preoperative percutaneous coronary intervention, and 9 patients (26.5%) underwent both of these procedures. The early mortality rate was 20.6%. Six patients (17.6%) required reoperation due to residual shunt or newly developed VSD. During follow-up (median, 4.8 years; range, 0 to 18.4 years), late death occurred in nine patients. Overall, the 5-year and 10-year survival rates were $54.4%{\pm}8.8%$ and $44.3%{\pm}8.9%$, respectively. According to a Cox regression analysis, preoperative cardiogenic shock (p=0.069) and prolonged cardiopulmonary bypass time (p=0.008) were independent predictors of mortality. Conclusion: The early surgical outcome of post-infarct VSD was acceptable considering the high-risk nature of the disease. The long-term outcome, however, was still dismal, necessitating comprehensive optimal management through close follow-up.

A clinical analysis of 138 cases of ventricular septal defect operated on from 1983 to June 1988 at the department of Thoracic and Cardiovascular Surgery, School of Medicine, Chung-nam National University was done. The following results were obtained. 1. The VSD were 27.6 % and 41.0 % respectively of 500 open heart surgery cases and 334 congenital heart disease. 2. The range of age when the VSD was repaired was 3 months to 45 years, the mean age was 10.4 years and the 53.6 % of patients were under 7 years. The sex ratio was 6:4 in males favor. 3. The two common symptoms were frequent upper respiratory infection and dyspnea whose frequency was 62.5 % and 58.7% respectively. 4. 52% of the patients was below 25 percentile of the standard body weight. 5. The most common chest PA findings were cardiomegaly and increased pulmonary vascularity. 6. On anatomical classification, perimembranous type was most common [65.5%], subpulmonary arterial type was 27.6 %, perimembranous plus subpulmonary arterial type was 3.4 % multiple VSD was 0.8 % and LV-RA defect was 2.6 %. 7. Associated cardiac anomalies were founded in 39 cases [35.5 %] and PDA and aortic valve prolapse were most common associated anomalies and extracardiac anomalies were founded in 6.7 % of patients. 8. Mean extracorporeal circulation time was 68 min. and mean aortic cross-clamping time was 42 min. 9. The postoperative complications developed in 26 % of patients and the most common one was minor wound infection. 10. Right bundle branch block developed in 54.8% of the patients who had right ventriculotomy, 40.0% of the patients who had right atriotomy and 10.5% of the patients who had pulmonary arteriotomy. 11. The overall operative mortality was 5.1 % and the operative mortality of the patients who body weigh under 10 Kg was 23.8%.

Purpose : The objective of this study was to assess ventricular function by tissue Doppler imaging (TDI) in children with congenital heart disease (CHD) who have been undergoing open heart surgery (OHS) using cardiopulmonary bypass. We tried to compare the parameters of tissue Doppler imaging before and after OHS in patients with congenital heart disease. Methods : This study was conducted on 32 patients with CHD after OHS from January 2005 to December 2005 at Kyungpook National University hospital. Patients who underwent 2-D echocardiography before and after their OHS. All patients were divided into three groups, left ventricular volume overloading group (group 1), and right ventricular volume overloading group (group 2), and right ventricular pressure overloading group (group 3). The TDIs were examined before and 1 to 3 months after OHS. Peak early diastolic (E), and peak late diastolic (A) velocity of transmitral flow were measured by pulsed wave Doppler examination. Peak systolic (Sm), peak early diastolic (Em), and peak late diastolic (Am) velocity in apical 4-chamber and 2-chamber views were measured by TDI. The author calculated E/Em ratio. Results : The patients were 14 boys and 18 girls and the average age of patients was 2 years and 3 months. The congenital heart diseases which have to get OHS were ventricular septal defect (13 cases), atrial septal defect (7), atrioventricular septal defect (3), isolated pulmonary stenosis (2) and tetralogy of Fallot (7). There were significant decrease of Sm, Em, Am measured on tricuspid annulus and E/Em measured on mitral annulus in apical 4 chamber view (P<0.05). Conclusion : This study showed significant decrease of Sm, Em, Am measured on tricuspid annulus and E/Em measured on mitral annulus in apical 4 chamber view after OHS. These changes might be due to the effects of cardiopulmonary bypass in OHS and/or hemodynamic changes after correction of congenital heart disease. To clarify these changes, further study on more patients is needed.

We r viewed a policy of primary surgical closure of large ventricular septal defects in small infants. Sixty-three infants met criteria for inclusion in the study, and were divided into two groups based on age: group 1 infants aged less than 5 months(n = 31), and group 2 infants aged 5 months or more(n = 32). Both groups had similar variation in ventricular septal defect location(paramembranous versus muscular), and showed no significant difference in left to right shunt and in ratio of systemic and pulmonary vascualr resistance. Three early deaths(9.7%) occurred in group 1, but no death(0%) in group 2. The causes of death were preoperative cardiac arrest and cerebral injury followed by postoperative respiratory insufficiency in two patients, and preoperative tracheomalacia followed by laryngeal edema and respiratory arrest in one Two patients in group 1 showed postoperative low cardiac output syndrome(6.5% in group 1 versus 0% in group 2). There was no late death during the follow-up per od in both groups. No surviving patients had postoperative patch leakage, or required a second operation. These results indicate that primary surgical closure of large ventricular septal defects, if logical perioperative care is accompanied, can be saefly performed in small infants aged less than 5 months with low postoperative mortality or morbidity rates.

Holt-Oram syndrome (HOS) is the most common heart-hand syndrome, which is inherited in an autosomal dominant manner, but most cases are sporadic. This condition is characterized by upper-extremity malformations involving radial-ray, thenar, and carpal bones, and congenital heart malformations including atrial septal defect and ventricular septal defect. It is caused by mutations in the TBX5 gene. In this report, a Korean case with HOS is described, which is inherited from her father. A novel nonsense mutation, $p.Glu294^*$, was identified. This is the first Korean case with HOS confirmed by genetic testing.

Between 2001 and 2006, 3 neonates that had multilevel left ventricular outflow tract obstruction and a ventricular septal defect underwent the Norwood-Rastelli procedure. The body weights ranged from 2.9 to 3.1 kg. The patients had a near normal sized mitral valve and left ventricle. We simultaneously performed a modified Norwood procedure with native tissues-to-tissue anastomosis without circulatory arrest, and a Rastelli type procedure using a non-valved conduit from the right ventricle to the pulmonary artery and intracardiac patch baffling from the left ventricle to the pulmonary valve via the ventricular septal defect. The postoperative courses were uneventful. During follow-up, there was one late mortality caused by a cardiac catheterization related complication at 7 months after surgery, One patient required a Rastelli conduit change. Two patients are doing well during a follow-up period of 1 and 5 years, respectively.

During 1986, 111 cases of open heart surgery were performed at Yeungnam University Hospital consisting 88 cases of congenital heart disease and 23 cases of acquired heart disease. Among 88 congenital heart disease, 72 were acyanotic group and 16 were cyanotic. Common congenital heart diseases were ventricular septal defect(51%), atrial septal defect(18%) and Tetralogy of Fallot(16%). Among 23 acquired heart disease, 22 cases were valvular heart disease and one was dissecting aortic aneurysm. Three cases of the postoperative death were present resulting 2.7% of surgical mortality rate.
