Quantification of Pulmonary Perfusion in Balloon Pulmonary Angioplasty

A 73-year-old female patient presented to our outpatient clinic with shortness of breath. She had a history of recurrent pulmonary embolism. We suspected she was suffering from chronic thromboembolic pulmonary hypertension (CTEPH). During a standard CTEPH workup (right heart catheterization, pulmonary angiography including C-arm CT), the patient was deemed inoperable and therefore scheduled for balloon pulmonary angioplasty (BPA). The mean pulmonary artery pressure at the beginning of the BPA sessions was 37 mmHg (norm: < 25 mmHg).
