Authors' conclusion

Among patients undergoing major cardiac surgery for advanced heart failure, inhaled pulmonary-selective vasodilator treatment using iEPO was associated with similar risks for RVF development and development of other postoperative secondary outcomes compared with treatment using iNO.

Study context

Population
Patients undergoing orthotopic heart transplantation or LV assist device implantation for advanced HFrandomized, eligible at surgery
Participants
231 patients
Comparison
Inhaled epoprostenol vs inhaled nitric oxide
  • Inhaled epoprostenol (iEPO)n = 120
  • iNOn = 111reference
Primary endpoint
Composite RV failure rate (after transplantation:
  • Mechanical circulatory support for isolated right ventricular failure (RVF)
  • After LV assist device: moderate
  • Severe right HF by INTERMACS criteria)

Primary result

As reported in the abstract

Risk difference

2.5 percentage points

90% one-sided CI −6.6% to 11.6%

Events by treatment group

iEPO vs iNO
risk difference 2.5 percentage points (90% one-sided CI −6.6% to 11.6%)

Secondary outcomes

Mechanical ventilation duration, hospital and ICU length of stay, AKI incl. renal replacement therapy, death at 30 days, 90 days and 1 year

No significant between-group differences
