Population

12 autopsied hearts: four with complete type common atrioventricular orifice (CAVO), two with atrial septal defect of the ostium primum type (ASD-I), two with ventricular septal defect of the persistent common AV canal type (VSD-C) and four without heart disease.

Intervention

Microscopic study of serial sections of the atrioventricular (AV) conduction system

Comparator

Normal control hearts without heart disease (n=4)

Outcome

Histopathological disposition of the AV conduction system and its correlation to the mean frontal QRS axis on ECGsurrogate

The study provides histopathological evidence that the postero-inferior displacement of the left bundle branch is responsible for the left axis deviation commonly observed in common AV orifice and related congenital anomalies.
