Abstract

The aortic root is a structure consisting of the lower part of the ascending aorta, sinotubular junction (STJ), annulus, cusps, aortic sinus of Valsalva, and coronary artery ostia. When considering the structure of the aortic root and its surroundings, confirming the structure of (1) the junction of the root of the pulmonary trunk (PT) with the right ventricular outflow tract (RVOT) as a basic concept makes it simpler to understand the precise structure of (2) the junction of the aortic root with the left ventricular outflow tract (LVOT).
