1 The morphologic nature of noncommitted ventricular septal defects in specimens with double-outlet right ventricle  Rudolf P. Beekman, MD, PhDa, Margot M. Bartelings, MD, PhDb, Mark G. Hazekamp, MD, PhDc, Adriana C. Gittenberger-de Groot, PhDb, Jaap Ottenkamp, MD, PhD, FESCa,d  The Journal of Thoracic and Cardiovascular Surgery  Volume 124, Issue 5, Pages (November 2002) DOI: /mtc Copyright © 2002 American Association for Thoracic Surgery Terms and Conditions

2 Fig. 1 Subaortic VSD. Right ventricle in specimen with DORV with an anteroposterior outflow tract. The Y of the septomarginal trabeculation (arrow) cradles the VSD. The arrow overlies the aortic orifice. The subpulmonary outflow tract (P) lies anterior to the outlet septum (OS) and is not stenotic.

3 Fig. 2 Subpulmonary VSD. Right ventricle in specimen with DORV with side-by-side outflow tracts. The Y of the SMT (arrow) cradles the VSD. The anterior limb (AL) of the SMT is not closely related to the outlet septum. The VIF is connected to the outlet septum (OS). The lateral outflow tract, which lies to the left and somewhat anterior on the figure, is subaortic.

4 Fig. 3 Noncommitted VSD. Right ventricle in specimen with DORV. The probe lies through the noncommitted muscular inlet VSD, which lies below the tricuspid valve on this figure and has no relationship with the septomarginal trabeculation (SMT), which has been sectioned. VIF, Ventriculoinfundibular fold; OS, outlet septum.

5 Fig. 4 Not-directly-committed VSD. Right ventricle in specimen with DORV. Aortic orifice (A) with broad ventriculoinfundibular fold (VIF) beneath it. On the figure the VSD, which opens into the outlet portion, lies to the right of the aorta and VIF and is cradled by the septomarginal trabeculation.

6 Fig. 5 Not-directly-committed VSD. Left-sided right ventricle with DORV in specimen with atrioventricular discordance, complete atrioventricular septal defect in which the anterior bridging leaflet (ABL) is seen passing through the VSD. The VSD has an inlet and outlet component. There is some distance from the outlet component of the VSD to the aortic orifice, which lies below the outlet septum (OS) on this figure.
