Gross morphology of the right ventricular inflow
and outflow tracts was analyzed to assess their normal
variations and abnormal findings associated with
various cardiac anomalies. Twenty cases of hearts
from autopsy series of the Seoul National University
Hospital were used, including 8 cases of abnormal
hearts, The diagnoses of abnormal hearts were single
ventricle, truncus arteriosus, tetralogy of Fallot,
transposition of great arteries, double outlet right
ventricle, atrioventricular canal and ventricular septal
defects respectively.
The results are as follows: 1. The size and location of papillary muscles
showed some variation in normal and abnormal
hearts. The medial papillary muscle showed some
variation within normal heart group. The muscle
portion of the medial papillary muscle was regularly
absent in abnormal hearts.
2. Bulbar raphe showed anterior convexity in
normal hearts but variations of the depth and anterior
convexity were present. Bulbar raphe was
regularly absent in abnormal hearts.
3. Septal and parietal bands showed mild variation
in normal hearts. They were fused together in
abnormal hearts. The bands of hearts with truncus
arteriosus, transposition of great arteries or double
outlet right ventricle were absent or ambiguous.
4. Abnormalities of resorption, rotation and inversion
of conal septum and bulboatrio-ventricular
ledge seem to result in various degrees of bulboventricular
malformation and also affect the structural
components of inflow and outflow tract of the right
