Monitoring myocardial recovery during induced hypothermia with a disposable monoplane TEE probe.

A 73 year old female with a history coronary artery bypass grafting and coronary stents had a witnessed cardiac arrest at home. She was transferred to an outside hospital and emergency heart catheterization revealed patent LIMA to LAD, stented grafts open, and no new culprit lesions. A temporary transvenous pacing wire was placed for bradycardia. She was transferred to the ICU where she was sedated and paralyzed for induction of hypothermia approximately five hours after the arrest. A miniaturized disposable TEE probe (Photo 1) was placed to allow ongoing monitoring of cardiac function and intravascular volume.
