Intraoperative Goal-Directed Perfusion Improves Outcomes in Left Ventricular Assist Device Explant Heart Transplantation.

Left ventricular assist device (LVAD) explant heart transplantation represents a metabolically vulnerable population with an increased risk for renal failure and mortality. Oxygen extraction ratio (O2ER), which integrates oxygen delivery and tissue oxygen demand, may provide a physiologic marker of cumulative metabolic...

Use of intraoperative right ventricular strain as a predictor of outcomes in adult heart transplant patients

Right ventricle (RV) evaluation in the perioperative period is challenging for anesthesiologists, given the limited objective assessment methods available for transesophageal echocardiography (TEE). Speckle-tracking strain imaging may offer a more objective evaluation of RV function. This study evaluated the predic...

Bridge or Burden? Heart Transplant Outcomes Following Left Ventricular Assist Device Explant in the Contemporary Allocation Era.

These findings suggest LVAD explant identifies a higher-risk transplant phenotype shaped by surgical burden, device-associated physiologic effects, and allocation-era transplant timing, rather than by intrinsic device-related risk alone.
