| Abstract |
|
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 evaluated for transcatheter closure of ASD; the results were compared with the operation diameter.
The result of study was as follows : 1) The (Qp:Qs) ratio have no significant(p>0.01) correlation with the operation diameter(r= 0.342)
2) The angiographic size have a significant(p<0.01) correlation with the operation diameter (r=0.842)
3) The echo diameter has the best correlation with the operation diameter(r=0.935; p<0.01)
The operation diameter can be estimated by the equation: 1.05¡¿echo diameter in millimeters+0.93mm.
It is concluded that operation diameter of ASD can be estimated accurately by two-dimensional subcostal echo measurements, which in turn could be used for selection of device size for occlusion of the ASD. |
