In this episode of SoCCC Pre-Rounds, Dr. Simon Parlow sits down with Dr. Jason Katz, advanced heart failure and transplant cardiologist, critical care leader, and president of the Society of Critical Care Cardiology, to dive into the real-world challenges of managing VA ECMO at the bedside.
ECMO can be life-saving, but it’s also one of the most complex tools in the ICU. Dr. Katz breaks down what every trainee needs to know: the difference between VV and VA ECMO, when and how to decide who’s a candidate, and why every cannulation must come with an “exit strategy.” He shares practical insights on navigating the first critical days, staying vigilant for complications like Harlequin syndrome, and when left ventricular venting makes sense.
If you’ve ever felt overwhelmed by the idea of managing a patient on VA ECMO, this episode gives you a clear, practical roadmap so you feel more prepared the next time you see an ECMO consult roll into the CICU.
Key Takeaways
The difference between VV and VA ECMO and why VA supports both the heart and lungs.
Classic indications for VA ECMO: when to consider it for refractory cardiogenic shock or cardiac arrest.
How to decide if your patient has a viable exit strategy, bridge to recovery, bridge to transplant, or bridge to decision.
Harlequin syndrome (differential hypoxemia): What it is, how to detect it, and what to do about it.
Pearls on left ventricular venting and unloading: when to consider a balloon pump, Impella, or atrial septostomy.
- Why multi-disciplinary shock teams are essential for real-time ECMO decision-making.

Notable Quotes
[10:18] "You need to think about how you're going to get off the device, again, whether you're hoping for recovery or it's a bridge to an exit strategy like durable VAD or transplantation." — Dr. Jason Katz
[13:48] "Transplantation as an exit strategy. But again, the longer these patients are on these devices, the ECMO is certainly the case. But for every temporary MCS device, the longer they're on these devices, the higher their risk for getting one of these complications." — Dr. Jason Katz
