Abstract

A patient who had had two coronary artery bypass grafts and an aneurysmectomy required intra-aortic balloon pump (IABP) assistance to allow discontinuation of cardiopulmonary bypass (CPBP). An indwelling electromagnetic flow probe on the ascending aorta was used to monitor IABP over the following 8 days of assistance. Stroke volume (SV), Cardiac output (CO), stroke work (SW), and ventricular afterload (VA) were measured directly. Recovery was indicated as the discrepancy between CO and SV on and off IABP decreased. VA depended upon the degree of augmentation. SW bore an incostant relationship to IABP.

Cardiac Aneurysm

Aneurysm refers to a bulge of the wall or lining of a vessel commonly occurring in the blood vessels at the base of the septum or within the aorta. In the heart, it usually arises from a patch of weakened tissue in a ventricular wall, which swells into a bubble filled with blood. Discover the latest research on cardiac aneurysm here.
