The 3D anatomy of cardiac conduction system in the intact human heart. This figure demonstrates high resolution (73 × 73 × 73 µm³) micro-CT data. From a single data set, the cardiac conduction system has been segmented (c,d) and overlaid on a semi-transparent or ‘ghosted’ rendering of the myocardium and great vessels (a,b). Panel (a) presents the view from the right side, and panel (b) from the left. The myocardium has been virtually sliced in the longitudinal axis to expose internal structures. Data is presented in the attitudinally correct position for the human, that is, in the upright posture. This 3D dataset is available in the supplementary material as a video (Supplementary Video S1) to demonstrate more clearly the insight that the dataset allows into the anatomical relations between the aortic root, the sinus node, the atrioventricular conduction axis, the atrial and ventricular septa and the bundle branches. Ao- aortic root, AVCA- atrioventricular conduction axis, CS- coronary sinus, FO- fossa ovale, LBB- left bundle branch, LCL- hinge of left coronary leaflet, LPN- left purkinje network, LV- left ventricle, MA- mitral annulus, NCL- hinge of non-coronary leaflet, RBB- right bundle branch, RCL- hinge of right coronary leaflet, RV- right ventricle, RVOT- right ventricular outflow tract, RPN – right Purkinje network, TA- tricuspid annulus.
