Three dimensional right ventricular diastolic vortex rings: characterization and comparison with left ventricular diastolic vortex rings from 4D flow MRI

Year: 2014

Type: article

Abstract: Background Efficient right ventricular (RV) pumping function requires optimal blood flow dynamics. In the left ventricle (LV), diastolic vortex ring formation distal to the mitral valve (MV) has been reported to be an important mechanism for such blood flow optimization. Earlier work based on computational fluid dynamic s( CFD) simulations using simplified RV geometry modeling have reported vortex ring formation in the RV during the early filling phase and its breakdown at the late diastolic phase. However, neither those CFD studies have characterized vortex rings nor have they been confirmed by 4D flow MRI. The purpose of this study was to investigate and characterize the formation of vortex rings during diastolic filling in the RV and to compare them with those of LV in healthy volunteers.
