We reviewed the clinical and hemodynamic studies in 10 patients with the isolated congenital mitral insufficiency. The patients ranged in age from 6 months to 16 years at the time of diagnosis and the incidence was 0.26% among the total congenital heart disease proven by cardiac catheterization and angiography. In two cases anterior mitral cleft was demonstrated by 2-D echocardiography and/or operation. In two cases left coronary artery was originated from pulmonary artery. Eight cases out of ten presented symptoms indicating varying degrees of left ventricular failure. Apical systolic murmur was heard in all except one, who had only triple rhythm. The electrocardiograms revealed left ventricular hypertrophy in 8 cases and biventricular hypertrophy in 2 cases. Roentgenographically left atrial enlargement was observed in 4 cases. Left arterial and ventricular dimension were increased in 7 cases by echocardiography. In 5 cases of them, pulmonary artery wedge pressure or left atrial pressure was increased. One patient died in congestive heart failure at the age of 10 months and one patient died postoperatively. Other 4 patients have been managed with medication without difficulty.

Over a continuous 4-year period, from January 1989 till December 1992, 7,100 infants were born in Department of Obstetrics and admitted to Nursery or Neonatal Intensive Care Unit of Department of Pediatrics of Seoul National University Children's Hospital. Among them, 126 cases were diagnosed as respiratory distress syndrome (RDS) of newborn. The total incidence of RDS among all the newborns (inborn) was 1.77%. And the incidence of RDS related to birth weight was 81.82% in infants of 500~749 g of birth weight, 68.57% in infants of 750~999 g of birth weight, 55.6% in infants of 1,000~1,249 g of birth weight, 35.71% in infants of 1,250~1,499 g of birth weight, 16.67% in infants of 1,500~1,749 g of birth weight, 9.82% in infants of 1,750~1,999 g of birth weight, 1.00%in infants of 2,000~2,249 g of birth weight, 1.29%in infants of 2,250~2,499 g of birth weight, and 0.08% in infants of more than 2,500 g of birth weight. Cumulative incidence of RDS related to birth weight was 81.82%in infants under 750 g of birth weight, 71.74% in infants under 1,000 g of birth weight, 62.39% in infants under 1,250 g of birth weight, 53.33% in infants under 1,500 g of birth weight, 39.85% in infants under 1,750 g of birth weight, 30.83% in infants under 2,000 g of birth weight, 20.42% in infants under 2,250 g of birth weight, and 13.70% in infants under 2,500 g of birth weight. The incidence of RDS related to gestational age was 83.33%, in infants under 25 weeks of gestation, 78.57% in infants at 25~26 weeks of gestation, 67.31% in infants at 27~28 weeks of gestation, 56.41%in infants at 29~30 weeks of gestation, 16.47% in infants at 31~32 weeks of gestation, 4.74% in infants at 33~34 weeks of gestation, 1.15% in infants at 35~36 weeks of gestation, and 0.05% in infants at more than 37 weeks of gestation. Cumulative incidence of RDS related to gestational age was 83.33% under 25 weeks of gestation, 80.00% under 27 weeks of gestation, 70.83% under 29 weeks of gestation, 63.33% under 31 weeks of gestation, 46.38% under 33 weeks of gestation, 27.76% under 35 weeks of gestation. Perinatal risk factors related to the incidence of RDS were analyzed by the multiple logistic regression statistical method in 595 infants, who were born under 37 weeks of gestation and under 2,500 g of birth weight in Seoul National University Hospital. The risk of RDS rose with decreasing gestational age (odds ratio=1.76, 95% CI=1.57, 1.99), with decreasing 5 minute Apgar score (odds ratio=1.23,95% CI=1.08, 1.40), while prolonged ruptrue of membranes of > 24 hours in the absence of maternal infection was highly protective (odds ratio=0.37, 95% CI=0.20, 0.70).

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.
