Pathophysiology
Anatomical Course of the Left Fascicle
The left posterior fascicle is a distal extension of the left main bundle and courses posteriorly toward the posterior papillary muscle which is located in the posterior, medial and inferior aspect of left ventricle and inferoposteriorly toward the left ventricular free wall. [1]
Blood Supply of the Left Posterior Fascicle
The proximal part of the left posterior fascicle is supplied by the artery supplying the atrioventricular (AV) node (often the right coronary artery) and, at times, by septal branches of the left anterior descending (LAD) artery.
