Abstract |
In order to find out the incidences of muscular ventricular septal defect and multiple ventricular
septal defects in cases with isolated ventricular septal defect, tetralogy of Fallot, complete endocar-
dial cushion defect, complete transposition of the great arteries, corrected transposition of the great
arteries and double outlet right ventricle, a retrospective analysis of 620 left ventriculograms were
performed. The surgical and echocardiographic findings were also considered to determine the
location and number of the defects.
The incidences of muscular defect were as follows; ventricular septal defect (2.1%), tetralogy of
Fallot (3.1%), complete endocardial cushion defect (0.0%), complete transposition of the great arteries
(12.1%), corrected transposition of the great arteries (12.5%) and double outlet right ventricle (9.1%).
The incidences of multiple defects were as follows; ventricular septal defect (0.9%), tetralogy of
Fallot (3.1%), complete transposition of the great arteries (9.1%), corrected transposition of the great
arteries (6.3%) and double outlet right ventricle (9.1%).
The incidence of muscular defect in isolated ventricular septal defect was lower than that of
western countries. However the incidence of multiple defects in the transposition of the great arteries
was not different from the result of the western study.
All those who had defect(s) in muscular septum only hade good prognosis. Even in the cases with
multiple defects, only a small proportion of the cases had surgically difficult lesions.
As the incidence of multiple or muscular defect are very low in isolated ventricular septal defect
and echocardigraphic accuracy of identifying muscular defect approaches 85%, the oriental patients
with isolated ventricular septal defect may undergo surgical correction without invasive studies with
neglible risk of residual muscular defect. |
