Relationship of Echocardiographic, Shunt Flow, and Angiographic Size to the Operation Diameter of the Atrial Septal Defect
Dae Kwon Hong, Hae Yong Lee, Baek Keun Lim
Clin Exp Pediatr. 1995;38(2):232-239.   Published online February 15, 1995
This report is based on analysis of admissions to the department of pediatric at the Wonju Christian Hospital during the 3 3/4-year period from January 1989 to September 1993 with an Isolated ostium secundum ASD. Several methods of assessment of ASD size, namely, echographic, pulmonary-to-systemic flow ratio(Qp:Qs), and angiographic measures, were undertaken in a group of 37 patients, who were being...
Comparisons of the Ratio of Pulmonary to Systemic Blood Flow(Qp/Qs) Determined by Non-invasive Doppler Echocardiography and Radionuclide-Angiocardiography in Congenital Heart Diseases.

Clin Exp Pediatr. 1989;32(7):943-950.   Published online July 31, 1989
This study was desinged to assess the accuracy of the ratio of pulmonary to systemic blood flow (Qp/Qs) measured by non-invasive continuous wave (CW) Doppler echocardiography comparing with other non-invasive Radionu- clide Angiocardiography (RNA) and invasive Fick method. Seventeen children with congenital heart disease, aged 14 months to 15 years, admitted for cardiac opention to this hospital, were studied. High correlations were found between the...
Studies on the Changes of Serum Osmolality Electrolytes, Digoxin-like Substance and Plasma Renin Activity Following Angiocardiography using Hypertonic Contrast Media.

Clin Exp Pediatr. 1987;30(4):398-405.   Published online April 30, 1987
Angiocardiography and cineangiocardiography have been employed with increasing frequency for the diagnosis of cardiovascular diseases. These commonplace technics of cardiovascular radiology depend upon the rapid injection of hypertonic contrast media into the heart or central circulation. In order to study the effects of concentrated radiopaque materials(Conray®, 1382 mOsm/L, 1-2 ml/ kg) on hemodynamic consequences, the changes of serum osmolality, sodium, potassium, chloride, digoxin-like substance and...

Clin Exp Pediatr. 1986;29(9):964-968.   Published online September 30, 1986
In 101 heart disease patients, the radionuclide angiocardiography(RNA) were performed. Quantitation of left to right shunts were obtained by RNA and oximetry method in 41 patients simultaneously. A comparison of the values for Qp/Qs ratio obtained by RNA & oximetry in those patients revealed a good correlation coefficient of 0.87(P
Comparative Study on Quantitation of Left to Right Shunts in Ventricular Septal Defect Using Oximetry and Radionuclide Method.

Clin Exp Pediatr. 1985;28(4):340-344.   Published online April 30, 1985
In 80 children with isolated ventricular septal defect, quantitation of left to right shunts was performed using oximetry and rdionuclide angiocardiography(RNA). The radionuclide angiocardiograms were acquired and analized by a gamma camera interfaced to a digital computer system. Pulmonary to systemic f!ow(Qp/Qs) ratios were calculated by analysis of pulmonary time-activity histograms using a gamma variate model. A comparison of the...
