Left ventricular-infundibular apical septal defect: a rare entity revisited.

Apical ventricular septal defects are a heterogeneous group of septal defects that need accurate anatomic characterisation for planning appropriate management. Left ventricular-infundibular apical septal defects are defects between the left ventricular septum and the infundibular apex of the right ventricle with distinctive morphological features. We describe two illustrative examples of this septal defect with focus on their therapeutic implications and long-term outcome.
