Different Approaches for Cannulation and Vessel Repair in VA ECMO

Priya Bhaskar, M.D. is an Associate Professor of Pediatrics at UT Southwestern and an attending in the Cardiac ICU at Children’s Medical Center Dallas. She completed her pediatric residency at Inova Children’s Hospital in Virginia and critical care fellowship at UTSW prior to completing a 1 year CICU fellowship at Laurie Children’s in Chicago. Prior to her current position here at UTSW she was a cardiac intensivist at Arkansas Children’s Hospital. Her professional interests include extracorporeal support and education. She serves on the ECMO team as a core staff physician, and she has co-authored a review on this topic that we will use to guide our conversation. 

Learning Objectives:

By the end of this podcast, listeners should be able to discuss:

1. The general indications for VA-ECMO in pediatrics.
2. The anatomic and physiologic rationale supporting various VA-ECMO cannulation strategies.
3. Physiologic targets to ensure adequate oxygen delivery for patients on VA-ECMO.
4. Hemodynamic complications of VA-ECMO such as left atrial hypertension and harlequin syndrome and general strategies in their management. 
5. Liberation strategies for VA-ECMO either to decannulation or conversion to ventricular assist device.
