Background Transcatheter treatment in post infarction ventricular septal defects can be unique and complex hence the development of a new technique is needed to improve outcomes. Summary We describe 2 cases in which a large and complex apical post infarction ventricular septal defects were treated with a novel transcatheter approach as salvage and the other due to refusal for open surgical repair. By direct externalization and enmeshment of a device to the right ventricular moderator band the defect was blocked, and immediate improvement of hemodynamics was achieved Conclusion In large, complex, apical post infarction ventricular septal defects with no apical rims, the DEXTER technique allows for exclusion of the defect and vestigialization of the right ventricular apex. An immediate and dramatic hemodynamic improvement can therefore be achieved.
