Reinnervation of the heart following cardiac transplantation. Cardiac reinnervation is highest in the left anterior descending (LAD) territory, followed by the left circumflex (LCX) territory, and lowest in the right coronary artery (RCA) territory.4, 11, 13, 49 It starts at the base of the anterior wall of the left ventricle (LV) and expands to the septal and lateral walls.3, 8, 9, 11, 33 The magnitude of reinnervation is highest at the anterobasal wall followed by the septal wall.7, 11 There is a gradient of reinnervation from the base to the apex of the heart.11 Ventricular reinnervation occurs prior to sinus node reinnervation.8
