Lecture Session 13: Pairing up Imaging and Morphology to Redefine Cardiac Anatomy (2020)-A Novel View on Malalignment Ventricular Septal Defects

A Novel View on Malalignment Ventricular Septal Defects

Video Transcription

Video Summary

The speaker explains how to describe ventricular septal malalignment more precisely by defining: which septal part is misaligned, relative to what structure, the mechanism, direction, and extent. Two main categories are outlined: outlet septal malalignment and whole ventricular septal malalignment. Using cartoons and examples, they compare tetralogy of Fallot, posterior malalignment causing LV outflow obstruction, and different forms of double-outlet right ventricle. They emphasize that some “Taussig-Bing” appearances are actually different morphologies, especially when the mitral valve straddles. Best imaging for assessment is a series of short-axis cine views from atria to apex.
