Cardio-pulmonary MRI for detection of treatment response after a single BPA treatment session in CTEPH patient s

Objectives Chronic thromboembolic pulmonary hypertension (CTEPH) can be treated with balloon pulmonary angioplasty (BPA) in inoperable patients. Sensitive non-invasive imaging methods are missing to detect treatment response after a single BPA treatment session. Therefore, the aim of this study was to measure treatment response after a single BPA session using cardio-pulmonary MRI.
