Intra-Aortic Balloon Pump (IABP) Intra-aortic balloon counter-pulsation is a method of invasive hemodynamic support. A catheter is placed through an arterial sheath and advanced into the thoracic aorta. A gas filled balloon at the end of the catheter inflates in sync with the cardiac cycle: • Balloon inflates in diastole → increases coronary perfusion • Balloon deflates in systole → decreases afterload & increases LV stroke volume (SV) The thick-walled LV is only perfused by the coronaries during diastole. By increasing diastolic pressure, the IABP improves coronary artery perfusion. • Triggers (EKG, Pressure) • Timing • Anticoagulation • Complications and Monitoring • Augmentation / Weaning by Nick Mark MD @nickmmark #IABP #IntraAortic #aortic #Balloon #Pump #diagnosis #management #cardiology #criticalcare
