Abstract
Application of the miniaturized ImaCor Trans-Esophageal Echocardiogram (TEE) probe in Heart Transplant/Mechanical Cardiac Support Patients In the surgical cardiac care unit (SCCU), therapeutic interventions often need to be done at the bedside, necessitating the need for a rapidly employable diagnostic tool for the cardiac intensivist. We report the clinical utility of the miniature ImaCor TEE-probe in guiding management of post heart transplant (H-Txp) and mechanical cardiac support patients (MCS) and describe the economic benefit of such a device. This is an IRB approved retrospective review of MCS/H-Txp patients who had ImaCor TEE monitoring in the SCCU of our institution in 2011. The effect on management was stratified into 3 categories; Major (tamponade/device selection/RV failure), Moderate (weaning support device guidance/ inotrope management/fluid management/hemodynamic instability) and Minor (line placement/useful data). The ImaCor TEE-Probe was utilized in a total of 34 patients, of which 21 were either supported by MCS or were post H-Txp. Of these, 13 were on ECMO, 9 were post-VAD, 3 supported by the Impella device and 4 were post-H-Txp. 6 patients were placed on more than 1 method of MCS and 1 patient was supported by ECMO after a H-Txp. The device had a Major effect on management in 4 patients (19%), Moderate effect in 13 (62%) and a Minor effect in 4 (19%). The cost difference between this new device and the traditional TEE is also significant (900 USD vs 4000 USD). Our institution saved in excess of 150,000 USD with the use of this device instead of traditional TEE. This figure did not include the ability of this probe to be used repeatedly within a 72-hour time frame, and the potential cost of going to the operating theatre for further management. This device has proven to be an invaluable new adjunct in the SCCU by allowing previously unobtainable continuous real time monitoring of the MCS/H-Txp patient. Use of the ImaCor TEE-probe provides the cardiac intensivist with timely important clinical data that improves patient care and is economically advantageous.
