Professor Salim Khalifah Kazem of the Department of Control and Systems Engineering at the University of Technology published a joint scientific paper, published in the journal of physics, in the Scopas Thomson Reuters classification:

 (Numerical investigation of the effect of aortic root engineering on internal flow stresses on the mechanical heart valve structure of the binary diffuser).

The researchers found that the stresses in BMHV may be caused by pulse blood flow in the valve failure. In this study, Von Mesis stress is computed and compared to BMHV, which is placed in two types of aortic root geometry, which is the aortic root with non-sinuses Replicas and with identical sinuses, at different physiological blood flow rates.

The researcher found that the von Mesis strain when BMHV was placed in the aortic root with asymmetric sinuses up to 47% higher than BMHV in the aortic root with identical sinuses under the same physiological conditions. The velocity vectors were observed to be high and then lead to increased stress of von Mesis to BMHV and placed in the aortic root with asymmetric sinuses that can lead to valve failure.
