We describe the steps for the percutaneous implantation of the intra-aortic balloon pump (IABP), a mechanical circulatory support device. It acts by counterpulsation, inflating at the onset of diastole, augmenting diastolic aortic pressure and improving coronary blood flow and systemic perfusion, and deflating before systole, reducing left ventricular afterload.
Overview
This article details the procedure for the percutaneous implantation of the intra-aortic balloon pump (IABP), a device that supports cardiac function through counterpulsation. The IABP inflates during diastole to enhance coronary blood flow and deflates before systole to reduce left ventricular afterload.
