Lecture Session 13: Pairing up Imaging and Morphology to Redefine Cardiac Anatomy (2020)-Ventricular Shape: How Do I Describe it and Does it Matter?

Ventricular Shape: How Do I Describe it and Does it Matter?

Video Transcription

Video Summary

The speaker argues that heart shape matters as much as volume in congenital heart disease, but normal MRI reference values are limited and based on small studies. They review evidence in single-ventricle disease, Tetralogy of Fallot, and Ebstein anomaly, showing that ventricular remodeling, bulging, sphericity, and annular tilt can affect function and strain. They also describe computer-based methods, such as atlas models and principal component analysis, to assess shape more objectively and efficiently. Overall, the talk suggests moving beyond simple volumetric measurements toward more precise, shape-based clinical assessment.
