dPmax for Predicting Right Ventricular Failure After Left Ventricular Assist Device Implantation
Predictive Value of dPmax Measured by Pulse Contour Analysis for Postoperative Right Ventricular Failure in Patients Undergoing LVAD Implantation
This single-center, prospective observational study aims to evaluate whether dPmax, a measure of the maximum rate of arterial pressure rise obtained through pulse contour analysis, can predict right ventricular failure after left ventricular assist device (LVAD) implantation in adults. Measurements collected during routine monitoring before and after anesthesia induction will be analyzed alongside preoperative echocardiographic findings. The primary outcome is right ventricular failure within 30 days after surgery, assessed using Mechanical Circulatory Support-Academic Research Consortium (MCS-ARC) criteria. Secondary objectives include comparing the predictive performance of dPmax with the ratio of tricuspid annular plane systolic excursion to pulmonary artery systolic pressure (TAPSE/SPAP) and identifying an optimal dPmax threshold for predicting right ventricular failure. No additional invasive procedures will be performed for research purposes.
