Does percutaneous left atrial to femoral artery mechanical bypass allow successful bridging to surgical LVAD in patients with medically refractory cardiogenic shock and severe aortic regurgitation?
Percutaneous left atrial to femoral artery mechanical bypass may serve as a viable bridge to surgical LVAD in patients with cardiogenic shock and severe aortic regurgitation, a condition where intra-aortic balloon counterpulsation is contraindicated.

May support percutaneous LA-FA bypass for bridging to LVAD in refractory cardiogenic shock with severe AR; hypothesis-generating, requiring prospective validation.
Severe aortic regurgitation (AR) is a well-established contraindication to intra-aortic balloon counterpulsation therapy. We report two cases of medically refractory cardiogenic shock in patients with severe AR who were successfully bridged to surgical left ventricular assist device implantation by percutaneous left atrial to femoral artery mechanical bypass. Further investigation into the clinical utility of percutaneous mechanical support in the setting of AR and shock is required.

Pham et al. (2012) conducted a case report in Medically refractory cardiogenic shock and severe aortic regurgitation (n=2). Percutaneous left atrial to femoral artery mechanical bypass was evaluated on Successful bridge to surgical left ventricular assist device implantation. Percutaneous left atrial to femoral artery mechanical bypass successfully bridged two patients with medically refractory cardiogenic shock and severe aortic regurgitation to surgical LVAD implantation.
