Objective
Air embolism is a serious complication of catheterization laboratory and may cause mortality and morbidity. Currently there is no device used for air embolism prevention during angiography and angioplasty procedures. In this study, we tested the flow Dynamics and efficiency of a new air holder device in virtual hemodynamic conditions.
Methods
The air holder device was hemodynamically tested by using Computational Fluid Dynamics (CFD) Software (ANSYS, USA). The device was introduced to the program as a three-dimensional (3D) design. Afterwards enjections were applied with standard coronary angiography pressures and volumes. 1 ml air was virtually added to the all injection flows. Flow waves, pressure and speed recordings were made.
