Summary

The EVOLVE-ECMO(Early Left Atrial Venting Versus Conventional Treatment For Left VEntricular Decompression During Venoarterial ExtraCorporeal Membrane Oxygenation Support) study is a randomized controlled trial to evaluate the prognostic effect of early LA venting(when detect B-line on serial lung ultrasound) on weaning VA-ECMO support in refractory CS who receive VA-ECMO support. The aim of EVOLVE-ECMO trial is to test the hypothesis that early LA venting would result in a significant reduction in failure of weaning ECMO support in refractory CS.

Conditions

  • Cardiogenic Shock
  • Extracorporeal Membrane Oxygenation Support
  • Refractory Pulmonary Edema

Interventions

PROCEDURE

Left atrial venting

The contralateral femoral vein is assessed with an 7-French(Fr) sheath() and femoral artery is assessed with 5-Fr sheath( ) for fluoroscopic guidance using 5-Fr pig-tail catheter. In some cases trans-esophageal echo is used. The inter-atrial septum in punctured with a standard BRK™tran-septal needle(St. Jude Medical Inc., St. Paul, MN) under direct visualization via an 8-Fr Mullin sheath(St. Jude Medical Inc.). A SAFARI™(Boston Scientific, Galway, Ireland) guidewire is advanced into the LA. An 8-Fr Mullin-sheath is removed and atrial septostomy is performed using 21-Fr dilator. A 17-Fr or 21-Fr Biomedicus Percutaneous Femoral cannula(Medtronic Inc., Minneapolis, MN) is then placed in the LA and was attached to the ECMO circuit using a Y connector.
