An observational study in Ventricular Dysfunction, Right, sponsored by Pınar Kırdemir. Recruiting at 1 site in Turkey (Türkiye). Open to participants aged 18 Years and older. Per ClinicalTrials.gov, last updated 2026-11-05.
Sponsored by Pınar Kırdemir · Observational
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.
90 studies on the registry are indexed under Ventricular Dysfunction, Right; 28 are open to participants now.
This study's planned enrollment of 89 is below the median of 100 across 51 observational studies indexed under Ventricular Dysfunction, Right.

Exclusion Criteria:
Underlined terms in the criteria open these too. Explained by clinicaltrials.gg, not part of the registry record. The study team decides who can take part.
Before you join, the study team explains what taking part involves — its purpose, what happens, the risks and possible benefits — and answers your questions, so you can decide freely. Consent is usually recorded on a form (the informed consent form, ICF) signed by you or, where the law allows, by someone legally authorised to decide for you.
You can keep asking questions during the study, you are told of new information that matters, and you can choose to leave at any time.
Relapsed: the illness came back after treatment had worked. Refractory: it did not respond to treatment, or stopped responding while still on it.

Arterial pulse contour analysis will be performed using the PulsioFlex monitoring system during routine invasive arterial monitoring for LVAD implantation. dPmax, representing the maximum rate of rise in arterial pressure, will be recorded before and after anesthesia induction. Absolute values and the relative change between measurements will be evaluated for their association with right ventricular failure within 30 days after surgery. No additional arterial catheterization or invasive procedures will be performed for research purposes.
Right Ventricular Failure Within 30 Days After LVAD Implantation
Time frame: 30 days after surgery.
Started Jun 2026 (actual). Primary completion is estimated for Sep 2029, 39 months after the start.
Of 25 observational studies under Ventricular Dysfunction, Right, half reached primary completion within 24 months of starting (the median), counting those still running; a quarter within 9 and three quarters within 26. This study's planned 39 months is above that.
