Abstract

PURPOSE: The proportion of interventional catheterization in congenital heart disease is being increased in Korea, especially in Sejong Heart Institute, so we performed statistical analysis on the cardiac catheterization cases.
METHODS
Total 233 cases of congenital heart disease confirmed by cardiac catheterization at the Sejong Heart Institute between Jaunary 1995 and June 1995 were analyzed retrospectively.
RESULTS
1) The distribution of age has become more younger than that of previous reports that is, the proportion of the infant less than 1 year old was 34.8%. 2) The proportion of male sex was equal to that of female. TOF and TGA were observed predominantly in male patients, and PDA and UVH revealed female preponderance. 3) The relative frequencies of each individual congenital heart disease in order of frequency were as follows; TOF 37.3%, PDA 13.3%, VSD 8.2% and UVH 7.7%. 4) Among the 145 (62%) cases of hemodynamic study pre-operation and post-operation cases were 85 and 60 cases, respectively. The cases of interventional catheterization were 84 (36%), and those of endomyocardial biopsy were 4 (2%). 5) The frequencies of each interventional catheterization of 84 cases in order of frequency were as follows: defect closure 28 cases, balloon valvuloplasty 20 cases, balloon angioplasty 17 cases, coil embolization 15 cases, and balloon atrial septostomy 4 cases. 6) There were 2 cases of mortality associated with cardiac catheterization.
CONCLUSIONS
The proportion of interventional catheterization in congenital heart disease is being increased in the Sejong Heart Institute, and this trend will spread to the other cardiac center in Korea.
