ABSTRACT:
Bicuspid aortic valve (BAV) disease is generally associated with thoracic aortic dilatation (TAD). Related factors include; genetical, morphological (valvular phenotype) and most recently, hemodynamic profiles associated with flow pattern and wall shear stress. Cardiac magnetic resonance 4D Flow (4DF) can give an integral evaluation of these later flow variables. Remarkable, different spectrums of flow and vortex direction exist in BAV that are related to the site of TAD (proximal or distal). Therefore, we present a 57 years old patient with BAV (Sievers 0) with anteroposterior leaflets distribution in which 4DF depicted an anteriorly and righthand oriented jet that correlated with the zone of grater AD; also, vortex rotation was counterclockwise, corresponding to the most frequent vortex type in BAV. In conclusion, 4DF is a powerful and ground-breaking tool that enhances our knowledge of BAV related aortopathy.
