Does balloon pulmonary angioplasty improve symptoms, exercise capacity, and haemodynamics in patients with inoperable chronic thromboembolic pulmonary hypertension?
Balloon pulmonary angioplasty is a safe and effective treatment for inoperable CTEPH, with outcomes improving over time due to a procedural learning curve.
AIMS: To evaluate safety and efficacy of balloon pulmonary angioplasty (BPA) in a large cohort of patients with chronic thromboembolic pulmonary hypertension (CTEPH). METHODS: From 2014 to 2017, 184 inoperable CTEPH patients underwent 1006 BPA sessions. Safety and efficacy during the first 21 months (initial period) were compared with those of the last 21 months (recent period). A total of 154 patients had a full evaluation after a median duration of 6.1 months. RESULTS: initial period) were the strongest factors related to the occurrence of lung injury. 3-year survival was 95.1%. CONCLUSION: This study confirms that a refined BPA strategy improves short-term symptoms, exercise capacity and haemodynamics in inoperable CTEPH patients with an acceptable risk-benefit ratio. Safety and efficacy improve over time, underscoring the unavoidable learning curve for this procedure.
