Description: Having removed the atrial myocardium forming the atrial surface of the triangle of Koch, and with the floor of the coronary sinus dissected away, the artery to the atrioventricular node is revealed. This artery lies in a paraseptal space between the atrial musculature and the crest of the muscular ventricular septum. The artery extends anteriorly to the apex of the triangle of Koch (red diamond). The non-coronary leaflet of the aortic valve and a portion of the septal leaflet of the tricuspid valve have also been removed, revealing the atrioventricular (yellow dots) and interventricular components of the membranous septum (red dots). Note the close relationship of the aortic valve, the membranous septum, and the tricuspid valve. The medial papillary muscle is marked with a yellow arrow.
