Bicuspid aortic valve fusion was associated with regional wall shear stress distribution, systolic flow imbalance and bicuspid aortic valve aortopathy in a recent study.
Researchers performed four-dimensional flow MRI in 75 patients to determine aortic valve anatomy and function. Patients were divided into three groups according to leaflet fusion pattern: 15 with right-left bicuspid aortic valve (RL-BAV; mid-altered ascending aorta diameter of 39.9 ± 4.4 mm); 15 with right-noncoronary bicuspid aortic valve (RN-BAV; mid-altered ascending aorta diameter of 39.6 ± 7.2 mm); and 30 aorta size-matched controls with tricuspid aortic valves and aortic dilatation (diameter of 41 ± 4.4 mm). The cohort also included 15 healthy volunteers with anatomically normal tricuspid aortic valves and no history of CV anomalies (diameter of 24.9 ± 3 mm). Full Story »
