On this episode of the Donut of Destiny, hosts Sotirios Evangelou, MD, FSCCT and Nisha Hosadurg , MBBS speak with guest Alan Vainrib, MD on how computational fluid dynamics (CFD) is emerging as a powerful research tool for understanding blood-flow behavior in structural heart disease. Using CT/MRI-based models, CFD can simulate pressures, velocities, shear stress and even post-procedure hemodynamics — offering new possibilities for evaluating aortic stenosis, planning TAVR and guiding mitral, tricuspid and LAAO interventions.
