intraaortic balloon counterpulsation

intraaortic balloon counterpulsation

a mechanical intervention by a device surgically placed in the lumen in the proximal aorta that affects deflation and inflation of a balloon, synchronized with the cardiac cycle. This intervention is aimed to reduce afterload (stress) and improve coronary perfusion by augmenting aortic pressure during diastole and decreasing it in systole. It is considered a palliative measure in patients with severe heart failure to maintain life until more definitive therapies can be effective. Used in emergency treatment for cardiogenic shock or intractable angina.

Thirty-seven percent of patients had compromised hemodynamics and required vasopressor drugs and intraaortic balloon counterpulsation. Each patient survived with normalized ejection fraction (mean 63%) (p<0.001) and rapid restoration to previous functional cardiovascular status within 6 [+ or -] 3 days.
Both groups were compared with each other from the aspect of postoperative need for intraaortic balloon counterpulsation (IABP), inotropic drug support, extubation time, length of intensive care unit and hospitalization stays, renal failure, stroke, malignant ventricular arrhythmia, atrial fibrillation, postoperative myocardial infarction and cardiac mortality.
After the operation, need for intraaortic balloon counterpulsation (IABP) or inotropic drug support, occurrence of low cardiac output syndrome (LCOS), malignant ventricular arrhythmias or atrial fibrillation, development of postoperative myocardial infarction, extubation time, length of intensive care unit (ICU) stay, neurological or renal complications, discharge time and cardiac mortality were recorded.
Use of intraaortic balloon counterpulsation in patients presenting with cardiogenic shock: observations from the GUSTO-1 Study.
The cuffs swiftly inflate at onset of diastole and rapidly deflate at onset of systole, providing hemodynamic effects similar to intraaortic balloon counterpulsation, including increased coronary artery blood flow along with afterload reduction.
