Coronary Anatomy (Dominance, Left Main anomalies) and Cardiac Cycle Mechanics (Pressure-Volume loops

Created using ChatSlide

This overview covers key aspects of coronary anatomy, including definitions of dominance and the territories of the right and left coronary arteries. It also addresses left main coronary anomalies, emphasizing the importance of recognizing variants and assessing ischemic risks using CTA. Additionally, the cardiac cycle is explored through pressure-volume loops, detailing the relationships between preload, afterload, and contractility, while linking loop shifts to various clinical states.
