From: Direct measurement of atrioventricular valve regurgitant jets using 4D flow cardiovascular magnetic resonance is accurate and reliable for children with congenital heart disease: a retrospective cohort study

Fig. 1

Graphic and mathematical depiction of the indirect methods calculating atrioventricular valve regurgitation (AVVR). a Ventricular stroke volume (SV) is the sum of AVVR and semilunar forward flow (SLFF); b AVVR is derived from the conservation of mass which assumes that atrioventricular net flow (AVNF) equals semilunar net flow (SLNF) in the absence of an intracardiac shunt
