About

to conduct a clinical investigation to determine if inhaled epoprostenol (Veletri®, iEPO) and inhaled nitric oxide (iNO) will have similar impact on outcomes in adult patients undergoing durable LVAD placement, heart transplantation, or lung transplantation 2. to conduct a cost-capture analysis on the expense each drug incurs per patient.

Full description

In adult cardiothoracic surgical patients, iNO is used to treat precapillary pulmonary hypertension (PH), right-sided heart failure (RHF), and ventilation-to-perfusion (V:Q) mismatch. Adult patients who undergo durable LVAD implantation (e.g. Heartware®, Heartmate 2®, or Heartmate 3®), cardiac transplantation for HFrEF, or those that have endured lung transplantation as a result of end-stage lung disease, compose the largest subpopulation which receives iPVD therapy at Duke University Hospital. iEPO may display an equivalent efficacy profile to iNO for pulmonary vasodilation and oxygenation and have a similar impact on clinical outcomes.

Subjects undergoing LVAD placement or heart transplantation (N=224) or lung transplantation (N=200) will be prospectively enrolled over a three-year period (one-year for follow-up). Patients will be randomly assigned 1:1 according to stratified randomization blocking either iNO or iEPO. Additional study procedures will involve data collection, blood, and tissue sampling.
