2.A Case of Coarctation of the Aorta Treated with Balloon Angioplasty.
Korean Circulation Journal 1990;20(1):135-140
Balloon dilatation angioplasty was performed in a 15 months old child with isolated discrete unoperated coarctation of the aorta. The peak systolic pressure gradient across the coarctation before balloon angioplasty was 80 mmHg, and immediately after balloon angioplasty it decreased to 19 mmHg. No significant complications were encountered during the procedure. No evidence of aneurysm formation and restenosis was seen on 6 months follow-up examination. Balloon dilatation angioplasty seems to be a safe and effective nonsurgical alternative for relieving the obstruction associated with discrete coarctation of the aorta.

3.A Study of the Effects of the Acute Pulmonary Artery Banding on Baroreflex Regulation of Sympathetic Nerve Activity in Rabbits.
Korean Circulation Journal 1995;25(6):1208-1216
BACKGROUND: Constriction or banding of the pulmonary artery to create pulmonary artery stenosis is a palliative procedure designed to limit pulmonary blood flow in congenital cardiac malformation with unrestricted left to right shunt. Activation of sensory endings such as the arterial baroreceptors results in an inhibitory endings in the heart. The purpose of this study is to test the hypothesis that acute pulmonary artery constriction(PAC) results in an enhanced cardiopulmonary inhibition of the arterial baroreflex. METHODS: Baroreflex control of renal sympathetic nerve activity(RSNA) were examined in rabbits before and during reversible PAC. New Zealand white rabbits were instrumented with an occluder around the main pulmonary artery, a right ventricular catheter, femoral artery and venous catheters, and recording electrodes around renal sympathetic nerves. Baroreflex mediated changes in RSNA were monitored during decreases and increases in mean arterial pressure. RESULTS: Acute PAC produced significant([<0.05) changes in mean arterial pressure(76.3+/-1.9 vs. 59.8+/-3.0mmHg), right ventricular systolic pressure(23.1+/-4.2 vs. 42.3+/-7.4mmHg), and resting RSNA(100 vs. 71+/-6.3%). The effect of acute PAC on the arterial baroreflex was characterized by decreases in RSNA range(103.0+/-1.3 vs. 83.8+/-3.8%) and gain (-3.5+/-0.2 vs. -2.6+/-0.2). CONCLUSION: Acute PAC significantly attenuates arterial baroreflex control of RSNA in rabbits. The attenuated arterial baroreflex regulation of RSNA may be result of an enhanced inhibitory influence from activated cardiac receptors.

Congenital tricuspid stenosis is an uncommon congenital heart anomaly. Tricuspid stenosis is usually associated with other anomalies, most commonly severe pulmonary stenosis or atresia with secondary hypoplasia of the right ventricle. Clinically it may be difficult to distinguish from tricuspid atresia. A case of congenital tricuspid stenosis in a 32 day-old-girl is presented. The patient had cyanosis and dyspnea. Echocardiographic study revealed tricuspid stenosis with right ventricular hypoplasia, atrial septal defect and pulmonary stenosis.

We experienced a case of congenital rubella syndrome manifesting patent ductus arteriosus, petechiae, microcephaly, intrauterine growth retardation, and hepatomegaly in one-day-old female newborn infant. Congenital rubella syndrome was confirmed by positive results of anti-rubella IgM in the sera of patient. Anti-rubella IgM was negative in the sera of mother, while anti-rubella IgG was positive.

Direct intraarterial measurement of blood pressure is an important diagnostic procedure in critical patients and premature baby care. Direct measurement was more accepted and confident method in physician than the indirect methods. But the presence of a significant amplification of systolic pressure in peripheral artery may lead to important error. So we have investigated the degree of the systolic pressure amplification from the ascending aorta to the femoral artery in children. Pressure waves recorded in the ascending aorta, aortic arch, diaphragmatic level of the descending aorta, common iliac artery, and femoral artery in 37 patients with congenital heart disease, aged 9 months to 21 years old (mean 7.16 yrs old) during diagnostic cardiac catheterization. The results were as follows 1) Amplification of the systolic pressure increased progressively from the ascending aorta to the femoral artery (16.7%) 2) Diastolic pressure decreased progressively from the ascending aorta to the femoral artery (6.5%) 3) Mean pressure decreased progressively from the ascending aorta to the femoral artery (1.5%) 4) Pulse pressure increased progressively from the ascending aorta to the femoral artery (42.8%) 5) There was significant drop (7%) of the systolic pressure of the ascending aorta compared with that of left ventricle. The results showed that the peripheral amplifications were limited to the systolic and pulse pressure, but the diastolic and mean pressure in peripheral arteries were lower than that of central artery.
