Clinical trials

Patients with CTEPH referred for evaluation and conduction of BPA undergo standard of care diagnostic tests and treatment. This includes conventional echocardiographic, RHC and non-invasive (CT/CMR) or invasive (coronary angiography) coronary artery disease work-up. BPA will be conducted in generally 5 to 6 consecutive sessions. CMR will be performed prior to first and following the last intervention. Patient recruitment will be performed within 3 years, that is the last BPA session of the last patient in will have been performed at 3 years time.

Patients will undergo quantitative perfusion assessment in cardiovascular magnetic resonance imaging (dual bolus or dual sequence approach) as well as invasive coronary angiography for assessment of fractional flow reserve (FFR) including assessment of coronary flow reserve (CFR) and microcirculatory resistance (IMR).
