In-hospital refractory cardiac arrest treated with extracorporeal membrane oxygenation: a tertiary single center experience.

Abstract We retrospectively assessed the experience of our tertiary care center on the use of venous-arterial extracorporeal membrane oxygenation (VA-ECMO) in 16 adult patients with refractory cardiac arrest. Cardiac arrest was due to acute coronary syndrome in 10 patients (62.5%), Takotsubo Syndrome in 1 patient (6.25%), dilated cardiomyopathy in 4 (25%) patients and massive pulmonary embolism in 1 patient (6.25%). The device was implanted in the catheterization laboratory in 14 patients (87.5%), in the operating room in 1 patient (6.25%) and in the emergency department in 1 patient (6.25%). During support, 7 patients were submitted to percutaneous coronary intervention, while coronary artery bypass grafting was performed in 1 patient, and cardiac surgery for repair of left ventricular wall rupture was performed in 1 patient. The device was successfully weaned in 6 patients (37.5%), among whom 2 patients died and 4 patients (25%) were discharged alive. In our institution 2/16 (12.5%) patients treated with VA-ECMO for refractory cardiac arrest survived to hospital discharge neurologically intact, and a good neurological function was observed in 3/16 (18.8%) at six-month follow-up.
