Key result
Simulation of controlled magnetic fields (HTC 60-80%) in aortic dissection models suggested local magnetic fields may relax aneurysm muscles while maintaining uniform blood flow distribution.
Why the study?
Aortic dissection causes hematocrit disturbances leading to oxygenation sensitivity that impairs imaging procedures in magnetic field-based interventions.
Scaled-controlled magnetic fields may help manage critical cardiovascular issues by maintaining uniform blood flow in aortic dissection models.
Model of AD flow and magnetic fields needs validation; leaves open clinical utility for OS-impaired interventions.
Aortic dissection (AD) is a complication that may considerably interrupts the flow of blood into vital organs. AD is implicated as the cause of hematrocrit disturbances which may lead to oxygenation sensitivity (OS) that impairs imaging procedure in magnetic field-based interventions. In this study, we utilised Einstein viscosity model to formulate a unified solution coupling wall deformation of AD effect, blood flow and magnetic field in a unified equation. Simulation was undertaken for varying HTC from 60% to 80% for selected controlled values of magnetic flux; pressure distribution in the region of AD showed rapidly increasing momentum and haemodynamic instability. We inferred that the contribution of local magnetic field is directed to relaxation of the muscles in the region of aneurysm while maintaining the blood flow at uniform distribution. Scaled-controlled magnetic effect may be suitable to management of critical cardiovascular issues such as necrosis in magnetic field environment.

Dare et al. (2021) studied Aortic dissection. Controlled magnetic field was evaluated on Pressure distribution and haemodynamic stability. Simulation of controlled magnetic fields (HTC 60-80%) in aortic dissection models suggested local magnetic fields may relax aneurysm muscles while maintaining uniform blood flow distribution.
