Effect of Phosphodiesterase-5 Inhibition on Systemic Right Ventricular Size and Function. A Multicentre, Double-Blind, Randomized, Placebo-Controlled Trial: SERVE
Authors' conclusion
In this trial in adults with systemic right ventricles, right ventricular systolic function, exercise capacity and neuro-hormonal activation remained stable over a 3-year follow-up period. No significant treatment effect of tadalafil was observed.

Primary result
As reported in the abstract
Difference
3.4 ml
95% CI −4.3 to 11.0
P = 0.39
Between Tadalafil and Placebo
difference 3.4 ml (95% CI −4.3 to 11.0); P = 0.39
Secondary outcomes
