Abstract Type-B aortic dissection (AD) is one of the greatest complex and fatal conditions with co-occurring disorders, challenging to treat. The initial treatment for patients presenting with AD is medical intervention to stabilize the condition. In the present study, a patient-specific geometry of type-B AD is generated from computed tomography images, and a three-element Windkessel lumped parameter model is implemented at the outlets to realistic boundary conditions. According to the physiological response of the antihypertensive drugs in the reduction of aortic blood flow and heart rate, three case studies with different heart rates have been created. Hemodynamic distributions including wall shear stress indicators, velocity and pressure are investigated and compared in each model. Results show that there is a considerable reduction in pressure furthermore, time-averaged wall shear stress (TAWSS) values decreased by 25% and 30%, respectively. Main goal is to critically analysis the use of biomechanical and computational simulation tools to measure hemodynamic parameters in the absence and presence of antihypertensive drugs. It would be of significant use to clinicians to improve diagnostic and treatment planning.
