Pulmonary stenosis and pulmonary regurgitation: both ends of the spectrum in residual hemodynamic impairment after tetralogy of Fallot repair
Byung Won Yoo, Han Ki Park
Clin Exp Pediatr. 2013;56(6):235-241.   Published online June 21, 2013

Repair of tetralogy of Fallot (TOF) has shown excellent outcomes. However it leaves varying degrees of residual hemodynamic impairment, with severe pulmonary stenosis (PS) and free pulmonary regurgitation (PR) at both ends of the spectrum. Since the 1980s, studies evaluating late outcomes after TOF repair revealed the adverse impacts of residual chronic PR on RV volume and function; thus, a...

Effects of Ductal Closure on Flow Velocities of Peripheral Pulmonary Arteries in Normal Term Infants
Hae-Soon Kim, Se Jeong Sohn, Young Mi Hong
Clin Exp Pediatr. 2000;43(10):1318-1322.   Published online October 15, 2000
Purpose : This study was performed to evaluate whether a relationship may exist between transient peripheral pulmonary stenosis and the closure of the ductus arteriosus in term infants. Methods : A total of 69 healthy full-term infants had pulmonary artery and ductal color Doppler flow velocity assessment performed at of 10 hours age(group I), 1-2 days of age(group II), and...
A Cause of Transient Systolic Murmur in Neonates Physiologic Pulmonary Artery Stenosis

A transient heart murmur is frequently heard in normal newborn who has no congenital heart disease. The cause of this murmur remains unclear but was speculated as hypoplasia of the pulmonary arterial branches or unusual alignment of the main pulmonary artery with its branches. Pulsed Doppler and two-dimensional echocardiographic studies were undertaken in 19 newborn infants with a transient murmur and...
Comparisons of the Pressure Gradients between Two-Dimensional Echocardiographic Doppler Studies and Cardiac Catheterization in Pulmonary Stenosis.

Clin Exp Pediatr. 1990;33(7):940-945.   Published online July 31, 1990
The right ventricular outflow tract pressure gradient measured by Doppler echocardiography was compared with the pressure gradient by cardiac catheterization in 19 children who were admitted to the department of Pediatrics, Dong San Hospotal during the period of 18 months from January 1987 to June 1988 for the evaluation of heart disease. Among 19 cases, 10 cases were Tetralogy of Fallot, 5 cases were...
The Estimation of Pressure Gradients of the various Cardiac Chambers Using Conbtinuos-Wave Doppler Echocardiography in Congenital Heart Disease.
Du Young Choi, Yeon Sim Kim, Hyung Suk Yoon
Clin Exp Pediatr. 1990;33(3):324-331.   Published online March 31, 1990
Continuous-Wave doppler echocardiography was used to estimate the Pressure gradient in 55 children with congenital heart disease. To test whether the Doppler method would be useful for evaluation and management of pediatric patients with ventricular septal defect (VSD)), pulmonic stenosis (PS), tricuspid regurgitation (TR), we recorded the maximal velocity (Vmax) of transseptal, pulmonary and regurgitant tricuspid jet flows and calculated the pressure gradients used by...
Percutaneous Balloon Valvuloplasty in Children with Pulmonary and Aortic Valvular Stenosis.
Chan Uhng Joo, Jung Soo Kim, Ho Yunh Song
Clin Exp Pediatr. 1989;32(9):1224-1231.   Published online September 30, 1989
Pulmonary and aortic valvular stenosis were relieved by percutaneous balloon valvuloplasty during cardiac catheterization on 14 children aged 22 months to 18 years. Before dilatation the transpulmonary systolic pressure gradients ranged from 43 mmHg (mean 87. 8 mmHg) in children with pulmonary valvular stenosis. There were significant reduction in the transpulmonary systolic pressure gradient (mean 33.1 mmHg) immediately after balloon valvuloplas- ty except one patient...
Percutaneous Balloon Angioplasty in Children with Pulmonary Valvular Stenosis.
Yong Soo Yun, Chang Yee Hong
Clin Exp Pediatr. 1987;30(12):1355-1362.   Published online December 31, 1987
Pulmonary valve stenosis was relieved by balloon dilatation during cardiac catheterization on 58 children aged 8 months to 15 years, mean 6.2 years. Pulmonary valve diameter was estimated by two-dimensional echocardiogrphy to assist in the choice of balloon size. Before dilatation the transpulmonary systolic pressure gradients ranged from 15 mmHg to 250 mmHg. There were significant reduction in the transpulmonary systolic pressure gradients immediately after...
