Balloon Pulmonary Angioplasty (BPA)

​UC San Diego Health performs the most balloon pulmonary angioplasty (BPA) treatments in the country. BPA is an emerging treatment for patients with chronic thromboembolic pulmonary hypertension (CTEPH) who are not good candidates for PTE surgery.  Our pulmonary vascular specialists have performed more than 100 BPA procedures since 2015, with many now done each week.

​Balloon pulmonary angioplasty is performed while patients are awake, in the cardiac catheterization lab by a multidisciplinary team specially trained in this intervention. BPA requires multiple procedures (in four to six separate sessions) to treat all the pulmonary vessels effectively.  Following BPA, patients typically spend one night in the hospital for observation and are discharged the next day.
