The pathology of cardiovascular interventions and devices for coronary artery disease, vascular disease, heart failure, and arrhythmias

In order to predict cardiovascular disease, it is imperative to study heart function carefully. This study examines the hemodynamics of the left ventricular and aortic vessels by selecting the proper boundary conditions. A further aspect of this study is the simulation of flow in the presence of an occlusion of the aortic vessels. In this study, fluid flow is analyzed using ANSYS CFX software, and cardiac geometry networking is performed using ICEM CFD software. Blood is assumed to be homogeneous, non-Newtonian, and pulsed. A significant reduction in pressure drop and heart rate is associated with stenosis of the coronary arteries. Consequently, it can pose severe risks to the patient. Having 50% stenosis of the arteries can reduce the pressure in the aorta by 33% and double the blood flow in the LSA. In addition, the maximum pressure is 136 mmHg for the patient in the normal state, 120 mmHg, and 104 mmHg for the patient with 30% and 50% stenosis, respectively.
