Impact of BPA in CTEPH on Cardiac and Pulmonary Physiology Assessed by CMR-derived 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.

Effects of Combination Medical Therapy Followed by BPA on Right Ventricular-PA Coupling and Hemodynamics in CTEPH

The main goal of this study is to determine the effects of combination medical therapy (Riociguat and Macitentan) and balloon pulmonary angioplasty (BPA) on hemodynamics and right ventricular (RV) function (including advanced assessments of RV-pulmonary artery (PA) coupling from invasive hemodynamics) in participants with inoperable or post-PTE residual CTEPH.

Effects of Pulmonary Rehabilitation on Quality of Life and Health in Pulmonary Arterial Hypertension Patients

Pulmonary hypertension (PH) is a major global health concern, affecting approximately 1% of the world's population. With global aging and increased life expectancy, its incidence continues to rise. PH is a progressive and disabling disease, with studies showing its progression correlates with worsening symptoms and increased mortality. Even with targeted medications, the prognosis remains poor across PH subtypes, with PAH patients showing only a 49% 7-year survival rate. The 2022 ESC/ERS guidelines emphasize that PH management requires a comprehensive, multidisciplinary approach. Beyond pharmacological and surgical treatments, rehabilitation has demonstrated benefits in improving exercise capacity, quality of life, functional class, and peak oxygen consumption. However, research on specific and effective comprehensive pulmonary rehabilitation programs remains lacking.

TrEatment Approach in the Multimodal Era Registry

The goal of this observational patient registry is to learn how expert centers treat patients with chronic thromboembolic pulmonary hypertension (CTEPH). CTEPH is a condition in which blood clots block the blood vessels in the lungs. There are currently three treatment options for patients with CTEPH: * surgery to remove blood clots from large vessels in the lungs (pulmonary endarterectomy (PEA)) * the use of a small balloon to unblock smaller blood vessels (balloon pulmonary angioplasty (BPA)) * drugs Patients can also receive a combination of these treatments. The main question this registry aims to answer are: * How many patients receive a given kind of treatment? * How do expert centers combine the different treatments? * Are patients doing better after they receive a given kind of treatment? * How many patients are alive 1, 3 and 5 years after they receive a given kind of treatment? Participants will receive the same treatments that they would receive if they did not participate in the study. During the study, patients will visit their doctors as they would do normally. The doctors will collect information on the patients' health and enter it into the study database. The follow-up time will be at least 3 years for all patients.

Biological Sex and CTEPH-related RV Dysfunction and Recovery (BIOSPHeRe)

1. To identify biological sex differences in baseline RV function in CTEPH 2. To identify biological sex differences in recovery of RV function after PTE surgery in CTEPH 3. To determine if sex hormone levels relate to RV function at CTEPH diagnosis and during recovery after PTE.
