Key result
Left atrial venoarterial extracorporeal membrane oxygenation resulted in hemodynamic improvement and stabilization for emergency valve-in-valve TAVR in a patient with severe aortic regurgitation.
Why the study?
Venoarterial extracorporeal membrane oxygenation is contraindicated in patients with severe aortic regurgitation.
Case Report (n=1)
Left atrial venoarterial ECMO can be successfully used to stabilize patients with cardiogenic shock and severe aortic regurgitation (where standard VA-ECMO is contraindicated) as a bridge to emergency valve-in-valve TAVR.
May support stabilization for TAVR in select acute AR shock cases; leaves open confirmation in prospective trials.
A 51-year-old man with past medical history of bioprosthetic aortic valve replacement presented in cardiogenic shock secondary to acute bioprosthesis degeneration with severe aortic regurgitation. Venoarterial extracorporeal membrane oxygenation is contraindicated in patients with severe AI. Use of left atrial venoarterial extracorporeal membrane oxygenation resulted in hemodynamic improvement, allowing patient stabilization for emergency valve-in-valve transcatheter aortic valve replacement. (Level of Difficulty: Advanced.)

Chiang et al. (2022) conducted a case report in Cardiogenic shock secondary to acute bioprosthesis degeneration with severe aortic regurgitation (n=1). Left atrial venoarterial extracorporeal membrane oxygenation was evaluated on Hemodynamic improvement and patient stabilization for emergency valve-in-valve transcatheter aortic valve replacement. Left atrial venoarterial extracorporeal membrane oxygenation resulted in hemodynamic improvement and stabilization for emergency valve-in-valve TAVR in a patient with severe aortic regurgitation.
