One of these patients had double valvar replacement because of both right and left atrioventricular valvar regurgitation.
The funnel consisted of myocardium that formed a continuity between the right wall of the atrioventricular canal and the ventricular septum.
Postoperative echocardiography showed a satisfactory intracardiac repair with no residual shunts and minimal regurgitation across the left atrioventricular valve.
The category of univentricular connections includes double inlet ventricles, along with absence of one atrioventricular connection.
In 4 of the patients, the presence of atrioventricular block was initially masked by the pre-excitation.
There was moderate degree of residual leakage at two commissures (instead of one) of die tri-leaflet left atrioventricular valve (vertical plane of left ventricle).
The atrioventricular connections through the common atrioventricular valve were equally shared between the ventricles.
Strong consideration should be given for permanent pacing in patients whose only source of atrioventricular conduction is via a bypass tract.
