TEE guided REBOA deflation following ROSC for non-traumatic cardiac arrest

Resuscitative endovascular balloon occlusion of the aorta (REBOA) is most commonly used to manage non-compressible torso hemorrhage. It is also emerging as a promising treatment for non-traumatic refractory cardiac arrest. Aortic occlusion during chest compressions increases cardio-cerebral perfusion, increasing the potential for sustained return of spontaneous circulation (ROSC) or serving as a bridge to extracorporeal cardiopulmonary resuscitation (ECPR). Optimal patient selection and post-ROSC management in such cases is uncertain and not well reported in the literature. We present a case of non-traumatic out-of-hospital cardiac arrest in which REBOA was placed in the emergency department with subsequent ROSC. Transesophageal echocardiography was used to guide post-ROSC REBOA management and balloon deflation.
