Ventricular septal defects is most common congenital cardiac anomaly in Korea and worldwide. And its clinical spectrum is well known. The anatomic classification had been undertaken by several authors, but recently Dr. Soto and Anderson's classification is widely used instead of Dr. Kirklin's it. From April, 1984 to December 1986, 99 cases of ventricular septal defects had been taken surgical repair under direct vision using conventional cardiopulmonary bypass technique at Yeungnam university hospital. The clinical spectrum was similar to other hospital, and postoperative mortality was 2%, the most common associated anomaly was patent foramen ovale, and the most common postoperative complication was incomplete or complete right bundle branch block. The rank of defects was as followings: 45 perimembranous inlet type, 21 doubly committed subarterial type, 17, perimembranous trabecular type, and 16 perimembranous outlet type. There was no muscular and mixed type.

A patient with non-ischaemic cardiomyopathy, and pre-existing atypical atrial flutter and left bundle branch block, developed broad complex tachycardia. In this unique and uncommon case of double tachycardia, we discuss the diagnostic approach of ventricular tachycardia in patients with broad complex tachycardia, and the use of different contemporary algorithms to help diagnose ventricular tachycardia and differentiate it from supraventricular tachycardia with aberrant conduction.

OBJECTIVETo summarize application experience of attain ® select II catheter delivery system for left ventricular lead implantation in cardiac resynchronization therapy (CRT).

METHODSCRT/CRT-D was applied for 86 patients with congestive heart failure and left bundle-branch block. Left ventricular lead implantation was applied without use of attain ® select II catheter delivery system in 42 patients without coronary vein anatomy variation (group A). Coronary sinus and cardiac vein angiography detected coronary vein anatomy variations in 44 patients and attain ® select II catheter delivery system was not used in 21 patients (group B) and used in 23 patients (group C). Total procedure time, LV lead implantation time, X-ray exposure time and complications were compared among groups. The optimal LV lead location were observed at the end of procedure.

RESULTSPatients were followed up to 245 days (160 - 368 days). Total procedure time [(119 ± 18) min vs. (142 ± 17) min; (119 ± 18) min vs. (143 ± 17) min], LV lead implantation time [(32 ± 7) min vs. (49 ± 8) min;(32 ± 7) min vs. (51 ± 7) min]and X-ray exposure time [(27 ± 6) min vs. (46 ± 84) min;(27 ± 6) min vs. (45 ± 7) min] were significant reduced in group C compared to group A and B. Procedure-related complications were similar among the 3 groups. The rate of optimal LV lead location was significantly higher in group C than in group B (96% vs. 71%).

CONCLUSIONSIt is feasible and safe to implant LV lead through coronary sinus with attain ® select II catheter delivery system. Applying Attain ® select II catheter delivery system can improve the rate of optimal LV lead location with coronary venous anatomy variation.

BACKGROUND: In the general population, the incidence of bundle branch block (BBB) is relatively low, and its effects on long-term prognosis have not been established. Previous studies on the incidence and correlation of BBB to clinical factors have produced conflicting results. However, the incidence of BBB was strongly related to age. This study aimed to describe the incidence of and risk factors for BBB in Korea. METHODS: In this study, 14, 540 adults (male 6, 573/female 7, 967) > or=40 years old received screening tests for general health between April and December 2000. Participants answered questionnaires and underwent examinations, which included blood pressure, electrocardiogram (ECG), total cholesterol and fasting glucose. The data analysis was performed using SPSS 10.0 for windows. RESULTS: The incidences of complete right bundle branch block (CRBBB) were 1.5 and 2.9% in people older than 40 and 65 years, respectively. Approximately 38.0% of individuals with CRBBB were older than 65 years. The incidence of CRBBB was higher in men than women at all age groups was highest in those aged 75-79 years. Males, advancing age (> or=65 years), hypertension and diabetes mellitus (DM) were associated with an increased risk of CRBBB. The incidences of complete left bundle branch block (LBBB) and bifascicular bundle branch block (BBBB) were 0.1 and 0.08% and 0.3 and 0.2% in those older than 40 and 65 years, respectively. Approximately 71.4 and 58.3% of individuals with LBBB and BBBB, respectively, were older than 65 years. Advancing age and cardiac disease were associated with an increased risk of LBBB. Advancing age was associated with an increased risk of BBBB. The most potent risk factor for BBB in this study was advancing age. CONCLUSION: The incidences of BBB were 1.7 and 3.4% in those older than 40 and 65 years respectively. Bundle branch block correlates strongly with age, and is common in the older ages groups. These findings support the theory that bundle branch block is a marker of slowly progressing degenerative diseases.

PURPOSE: The importance of postoperative management of those who have undergone intracardiac repair for congenital heart diseases has increased in recent years. In this study, we investigated postoperative complications and their relations to preoperative age or duration of the intubation and artificial ventilation in infants with large symptomatic ventricular septal defect. METHODS: Between January, 1993 and December, 1996, sixty infants underwent primary closure of a ventricular septal defect (VSD). The patients were divided into two groups based on preoperative age : group 1, infants aged 6 month or less (n=40), and group 2, infants aged more than 6 month (n=20). And, another three groups were divided into 3 groups due to the duration of the intubation and artificial ventilation including < 24 hour and 24-48 hour, >48 hour, respectively. We compared the incidence of complications such as infection, respiratory or cardiovascular complications among each group. RESULTS: No specific differences between two age groups were found, but the incidence of right bundle branch block was high in age group of 6 month or less (P<0.05). The incidence of sepsis was high in group of >48 hour (P<0.05). And also, arrhythmias, atelectasis, toxic hepatitis were more frequently observed in the former group. CONCLUSION: These results indicate that early weaning of the artificial ventilation in infants with large symptomatic ventricular septal defect could protect them from development of severe life- threatening infection such as sepsis. We suggest 48 hours or less as the optimal duration of artificial ventilation. Additionally, earlier weaning could provide earlier oral feeding or earlier ambulation, which is improve respiratory homeostasis.

Malignant lymphoma can involve the cardiac cavity or myocardium as a mass. Clinical symptoms of its cardiac involvement are usually absent or nonspecific, making the diagnosis of the cardiac involvement very difficult before death. We experienced a patient with secondary myocardial non-Hodgkin's lymphoma presenting with sustained ventricular tachycardia (VT) as a primary clinical problem. A 39-yr-old woman visited our hospital because of dyspnea and palpitation for 7 days. Physical examination revealed rapid heart beat with variable intensity of the first heart sound and soft mass in the lower abdomen. VT with a cycle length of 480 msec was recorded in resting 12-lead electrocardiogram. Two well-circumscribed hypo-echogenic round masses were demonstrated in the interventricular septum and left ventricular posterior wall. Cytological examination of aspirated pericardial fluid and percutaneous needle biopsy of the abdominal mass revealed a diffuse large cell type non-Hodgkin's lymphoma. Myocardial masses and ventricular tachycardia resolved with chemotherapy using cyclophosphamide, adriamycin, vincristine and prednisone regimen. To our best knowledge, the same case as ours has not been reported previously.
