A 66-year-old man was undergoing transesophageal echocardiography in preparation for valve surgery for aortic stenosis when he experienced respiratory arrest during the procedure. The transesophageal echocardiography probe was withdrawn, and his ventilation was assisted using a bag-valve mask. The patient then experienced significant bradycardia with hypotension and a code blue was activated within the hospital. On arrival, the code team noted an agonal rhythm on telemetry. Blood pressure and oxygen saturation readings were unable to be obtained. A pocket-sized ultrasonographic device (Vscan, GE Healthcare) carried by a cardiologist responding to the code recorded subcostal views intermittently throughout the resuscitation (Video 1).
