From January to December 1984, 191 patients with associated ventricular septal defect(VSD) were studied in the cardiac cathetherization laboratory. Among theses 191 cases, 58 cases(30.4%) of subpulmonic VSD were identified by angiocardiography. Among the 59 cases of subpulmonic VSD, 12 cases(20.6%) were complicated with aortic infficiency(AI). The relative frequency of subpulmonic VSD increased with the increase of age and the frequency of complication of AI with the subpulmonic VSD also increased with the increase of age. The amount of left to right shunt in the patients with subpulmonic VSD and AI was small and Qp/Qs ratio was less than 2.0 in all of the 12 cases. Among the 12 patients 4 cases had a pressure gradient greater than 20 mmHg across the infundibular region of the right ventricle.

We evaluated the accuracy of a noninvasive method for estimating right ventricular systolic pressures in patients with atrial septal defect and tricuspid regurgitation defected by two-dimensional and Doppler ultrasound. Of 54 patients with atrial septal defect, 24(44%) had jets of tricuspid regurgitation. By use of the maximum velocity(V) of the regurgitatant jet recorded by continuous wave Doppler ultrasound and the Bernoulli equation, we predicted right ventricular systolic pressure(RVP) calculated by the equation of RVP=4V2+10 proposed by Tei et al.The values correlated well with catheterization values(r=0.851, standerd error of estimate=4mmHg). In addition the relation between the Lt to Rt shunt amount and the severity of tricuspid regurgitation was assessed. The severity of tricuspid regurgitation graded on a four-pointscali by pulsed Doppler and two-dimensional echocardiography correlated with Qp/Qs ratio calculated by the Fick's method(p<0.05).

A case of chronic atrial tachycardia in a 12-year-old boy is reported. His complaints were frequent precordial palpitation and mild exertional dyspnea with 6 months duration, EKG showed the findings of chronic atrial tachycardia, repetitive type. Digitalis therapy was established and continued for about 6 months. The attack of tachycardia ceased from 2 weeks after beginning of the treatment and didn't reappeared until the end of treatment. After cessation of digitalis therapy, follow-up study was made for over 6 months but no attack of tachycardia was observed even during this period. A review of literatures was made briefly.

Hypoplastic left heart syndrome is a rare congenital heart disease. This is a universally fatal leison, and approximately 80% of patients die within the first week of life. The diagnosis should be considered in infants, with the sudden onset of heart failure, systemic hypoperfusion and cyanosis. 2 cases of hypoplastic left syndrome are presented with review of related literatures.

Thirty - five cases of coarctation of aorta, diagnosed by cardiac catheterization and angiography during the period of 1980-1984, at the department of Pediatrics of Seoul National University Hospital, were studied on the clinical features and management. The followoing results were obtained : 1) The incidence of coartation of aorta was 1.2% of congenital heart disease and sex ratio of male to female was 2.2 : 1. 2) The anatomical type of coarctation was preductal in 19 cases, juxtaductal in 15 cases and postductal in 1 case. Most of preductal coarctation (89.5%) were associated with aortic arch or isthmus hypoplasia. 3) All of these patients had various type of additional cardiac anomalies and among them, PDA was the most common associated lesion and followed by VSD. 4) Significant BP gradient between upper and lower extremies and weak femoral pulsation were noticed in 15 cases(42.8%). 5) Congestive heart failure was present in all but one patient less than 1 year old, while only 3 cases(15%) had congestive heat failure in patients older than one year. 6) Overall surgical mortality was 31.8%, but significant decrease in surgical mortality was found since 1983.
