Impact of Balloon Pulmonary Angioplasty in CTEPH on Cardiac and Pulmonary Physiology as Assessed by State-of-the-art Cardiovascular Magnetic Resonance 4D Flow Haemodynamics

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.
