73:The Hyperinvasive Trial with Jan Belohlavek

Wait…ECPR works?

To the believers, this has been a foregone conclusion.  To the rest of the world, the question of whether ECPR improves cardiac arrest survivorship has been in question. Jan Belohlavek and his Prague colleagues just presented their 8 year data showing better outcomes in cardiac arrest patients that got a grouped therapy of early transport, prehospital targeted temperature management, mechanical chest compressions, and ECMO over those who got a traditional resuscitation.  This study is key and contrasts to the Oslo study that we reviewed just a few months earlier.  Jan speaks with Zack about the details of the results and what were the keys to their success.

72: Should We All Switch To Bivalirudin?

Heparin has been the mainstay of anticoagulation for ECMO patients for years.  In recent years, this has been challenged.  Bivalirudin has become a potential better anticoagulant.  Troy Seelhammer in EDECMO episode 55 gave us some insight into this.  This month Ryan Rivosecchi and his crew at UPitt have released their findings in Critical Care Medicine.  This retrospective study suggests great improvement in major bleeding in patients who received Bivalirudin compare to Heparin (40.7% vs 11.7%, p < 0.001).  Listen to Ryan and Zack discuss anticoagulant use in ECMO patients in this month's episode.

68: ARREST – The First Randomized ECPR Trial Ever

 

 

 

 

 

 

The ARREST Trial is published!  Demetris Yannopoulos, Jason Bartos and their army of rockstars have done it!  This is the first randomized ECPR trial and it showed tremendous benefit of ECPR compared to traditional therapies.  Zack explores this paper and their concurrent publication of process with Demetris.   Their two Lancet papers are below

67: Da DO2: Fundamental ECMO Physiology with Sage Whitmore

Have you ever wondered about how initiating ECMO changes the cardiovascular physiology?  Have you wondered what metrics you should be looking at when resuscitating a patient that has a beating heart and a ECMO flow?  Dr. Sage Whitmore, an ED Intensivist from Nashville with ECMO training from UMichigan, leads us through the basic to the tough questions of ECMO physiology.online pharmacy

65: ECPR Journal Club: Dual Sequential Defibrillation, CT after ECMO, and much, much more

This month we tackle a number of topics.  Garrett Sterling is back again with Zack to talk about cutting edge resuscitation, ECMO, and the interplay between the two.  Dual sequential defibrillation, CT after ECMO initiation, should you perform bystander CPR in the era of Covid, some US ECMO data, and an awesome 3D modeling for ECPR training models.  All in one 30 minute podcast!

64: Contraindicated??? – Long Live the Aortic Dissection with Garrett Sterling

Aortic Dissection is a contraindication for ECMO….or is it?  In this episode, Zack Shinar and Garrett Sterling discuss the sticky topic of ECMO for aortic dissection.  They discuss a recent case where Joe Bellezzo, Karl Limmer, Craig Larsen, and the entire Sharp team save a Type A aortic dissection with cardiac arrest.

Zack and Garrett traverse the details around ECMO in aortic dissection ranging from VA ECMO in ECPR to VVECMO for pulmonary edema.  They go through the literature on the subject and make some conclusions based on this data. The ultimate question – “Is Aortic Dissection a Contraindication for ECMO?”

62: Jason Bartos Take 2: The Future of ECPR Now

Last month you heard Jason talk about the ECPR program at the University of Minnesota.  This month Zack and Jason talk about post initiation care and the crazy ECPR realities that Demetris, Jason and U of M have created.  The sky is the limit for their team!

61: Jason Bartos – ECPR Redefined

Jason Bartos and his crew at the University

Image result for university of minnesota cardiology"

of Minnesota have revolutionized the concept of ECPR for out of hospital cardiac arrests.  His crew are interventional cardiologists who take OHCA straight to the cardiac cath lab.  They have initiate times of around 6-8 minutes and have neurologically intact survival rates higher than 30%.  Below are two of Jason’s recent papers which every person who considers themselves an ECPR fan should pour over with a fine-toothed comb.  There is so much in these papers.  We split this interview into two pieces because there is so many pearls in it.

 

Outcomes

Resuscitation paper – 48% survival in 100 patients

Circulation paper 2020– 33% vs. 23% ALPS

  • Cohort who had VF/VT and one shock vs. a cohort who had VF/VT and failed to ROSC at the scene, in the ambulance, and then all the way to the hospital.
  • OHCA – > Straight to the Cath lab –> Get on ECMO –> Go to CCU under Cards care.
  • Inclusion criteria – Vf/vt, lactate <18, paO2 >50,ETCO2>10

60: ECPR 2.0 with Scott Weingart

     We've had some recent episodes on ECMO physiology.  Today's episode focuses on the differences between ECMO physiology in the patient in cardiogenic shock versus the one in cardiac arrest. Scott Weingart talks with Zack about how the difference between these two patient populations is HUGE!  Scott also mentions details about cannulation and some critical post ECMO initiation pearls.

58: First U.S. Pre-Hospital ECPR Program

The U.S. has seen pre-hospital programs spring up in Paris, UK, and Australia.  It was thought that due to billing issues this could never happen in America….but it has.  Jon Marinaro and Darren Braude have accomplished this against all odds.  Zack interviews the two of them on how they were able to accomplish this task amidst the many financial, logistic, and medical problems surrounding this monumental task.
