A single center tertiary care experience utilizing the large volume mega 50cc intra-aortic balloon counterpulsation in contemporary clinical practice.

Objective: Clinical outcomes and adverse events utilizing the large volume 50cc intra-aortic balloon (IAB) in contemporary clinical practice.

Background: The newer large volume 50cc IAB, recently introduced into clinical practice offers improved diastolic augmentation and better left ventricular (LV) unloading compared to the older 40cc IAB.

Methods: In 150 consecutive patients who received intra-aortic balloon counterpulsation (IABC) with a 50cc balloon from 2011 to 2015, we retrospectively analyzed demographic, clinical, laboratory, and hemodynamic variables, adverse events and survival to discharge from index hospitalization.
