Intra-Aortic Balloon Counterpulsation - Pump (IABP):
A slender polyurethane balloon mounted on a catheter is placed in the descending thoracic Aorta with tip just distal to origin of left subclavian artery. A Console shuttles helium in and out of the balloon thus inflating and deflating it.
The balloon inflates during diastole thus causing augumentation of diastolic pressure, coronary perfusion and increasing MVO2 supply.
In Systole the balloon is deflated thus causing a decrease in aortic pressure, afterload and cardiac work. Myocardial oxygen consumption decreases
and cardiac Output increases.
Secondary effects associated with counterpulsation include a decrease in heart rate, systemic vascular resistance,left end diastolic pressure or PCWP, an increase in cardiac output and mean arterial pressure.
• Neuro: - Increase cerebral perfusion
• Renal: - Increase renal perfusion
• Vascular: - a decrease in SVR with an improvement in peripheral perfusion
• Respiratory: - a decrease in PADP /PCWP with a resultant improvement in respiratory function.
Indication for Use of IABP:
• Weaning from Cardiopulmonary Bypass
• Support during PTCA
• Acute Myocardial Infarction
• Unstable Angina
• Stunned Myocardium
• Bridge to Cardiac Transplantation
• Septic Shock
• Transport of Patients
• Paediatric Patients: What all of them??!!
