Figure 1: Pulmonary valve (morphological points): Parasternal short axis view – (a) Basal muscular ring (1); body of cusps in between the basal ring and Sino-tubular junction (2); sinotubular junction or cranial attachment (3) a site of supravalvular PS. Red stars are points for PV annular measurement; TV attachment and muscular sleeve between TV and PV (yellow star and yellow broken line). (b) Three-dimensional CT angio showing pulmonary valve from outside (pink lines demarketing extent of pulmonary valve). (c) Morphological points - A parasternal short axis view. Classical “Cup and saucer” view due to obliquity of infundibulum a muscular sleeve distancing TV and PV; shared wall of left ventricular outflow with RVOT (green), MPA (yellow), RPA (violet); various sites of possible obstruction are shown (infundibular, valvular, supravalvular, bifurcation and branch pulmonary arteries.). PS: Pulmonary stenosis, PV: Pulmonary valve, TV: Tricuspid valve, CT: Computed tomography, RVOT: Right ventricular outflow obstruction, MPA: Main pulmonary artery, RPA: Right pulmonary artery
