Comparison of levosimendan, NO, and inhaled iloprost for pulmonary hypertension reversibility assessment in heart transplant candidates.

ABSTRACT:

Aims

Assessing reversibility of pulmonary vascular changes through vasoreactivity testing (VRT) optimizes end-stage heart failure patient selection for heart transplant. All efforts should be made to unload the left ventricle and reduce pulmonary vascular resistance to effectively exclude irreversible pulmonary hypertension.

Methods and results

We reviewed our centre's cardiac transplant registry database (2009-2017) for VRT and compared haemodynamic responses with 40 ppm inhaled NO (n = 14), 14-17 μg inhaled iloprost (n = 7), and 24 h 0.1 μg/kg/min intravenous levosimendan (n = 14). Response to levosimendan was assessed by repeat right heart catheterization within 72 h. Baseline clinical and haemodynamic features were similar between groups. VRT was well tolerated in all pa
