Corrected 23 Oct 2026: Measure wording clarified; no values changed.
Authors' conclusion
Occlusion morphology has a significant impact on BPA success and complication rates.
Study context
- Population
- Patients with chronic thromboembolic pulmonary hypertension (CTEPH) undergoing balloon pulmonary angioplasty (BPA) with total occlusion, Fuwai Hospital, Beijing, May 2018–May 202238 occluded lesions in 33 patients
- Participants
- 204 patients
- Exposure
- Pointed-head vs round-head vs orifice total occlusion in BPA
- Outcome
- BPA success by occlusion morphology
