Completed · 2017 until 2021
Engel Reto, Gemperle Michaela
This study assesses in a pilot trial the effect of PDE-5 inhibition with Tadalafil on RV size and function, exercise capacity and neurohumoral activation in adults with a systemic RV over a 3-year follow-up period.
Included patients: Adults (≥18 years) with a systemic RV due to D-TGA repaired with an atrial switch procedure or due to ccTGA.
Excluded: myocardial infarction, stroke, or open heart surgery in the previous 3 months; expected heart transplant within the next 6 months
Primary endpoint: Change in mean end-systolic RV volumes (RV ESV) from baseline to study end at 3 years
Secondary endpoints: Change in mean systemic RV ejection fraction (EF); Change in exercise capacity measured as peak VO2 during cardiopulmonary exercise testing and change in serum neurohormonal activation.
