Definitions for Left Ventricle Metrics

This section aims to provide basic definitions and standard practices for the identification of left ventricle features.

Basic Definitions:

• Longitudinal Line: Line formed between Apex and Base reference nodes.

• Normal vector: Vector based on longitudinal line as “Apex” to “Base”

Geometry Types:

• Ideal: Geometry created based on ellipsiod.

• Type A: Geometry created based on patient-specific data with one large opening (no Mitral or Aortic structures).

• Type B: Geometry created based on patien-specific data with two openings: Mitral and Aortic valves.
