Troubleshooting Total Artificial Heart: Novel Use of Implantable Hemodynamic Monitor

Vinh Q Chau et al. JACC Case Rep. .

Abstract

Accurate device optimization of the Syncardia temporary total artificial heart is difficult while waiting for heart transplantation. In this challenging clinical cohort, using an implantable hemodynamic monitor (CardioMEMS HF system) can assist in volume and hemodynamic assessments. (Level of Difficulty: Advanced.).

Keywords: CardioMEMS; IHM, implantable hemodynamic monitor; TAH, temporary artificial heart; TAH-t, Syncardia temporary total artificial heart; heart failure; mechanical circulatory support; pulmonary artery hypertension; total artificial heart.

Significant Pulmonary Edema Involving Both Lungs With Effusions on Chest X-Ray and CT at Baseline BR of 115 beats/min (A) Hemodynamics via implantable hemodynamic monitor (IHM) interrogation at low (110 beat/min) and high (135 beats/min) beat rate (BR) (B and C) in supine and sitting positions showing that at a higher BR, there is a decrease in pulmonary pressures, suggesting adequate volume unloading. (D) There was marked improvement in airspace opacities on follow-up chest x-ray and implantable hemodynamic monitor readings after increasing BR and further diuresis. CT = computed tomography; PA = pulmonary artery.
