Dynamic anatomic relationship of the coronary arteries to the valves. Part 1: mitral annulus and circumflex artery

Introduction

Mitral regurgitation (MR) represents one of the most common valvular heart diseases affecting almost 10% of the population >75 years of age1. According to the American College of Cardiology/American Heart Association, surgical interventions still represent the gold standard for treatment of severe MR2. However, many patients do not undergo surgery due to increased surgical risk, which has driven the field of percutaneous mitral valve (MV) treatments, including repair and replacement technologies3. As catheter-based MV repair options are increasingly adopted in clinical practice, they require accurate preprocedural imaging, providing detailed anatomic information about the MV and adjacent structures ...
