Balloon pulmonary angioplasty
For CTEPH patients ineligible for pulmonary endarterectomy (PEA), or who have recurrent or persistent pulmonary hypertension after surgery, balloon pulmonary angioplasty (BPA) is an emerging option, and promises haemodynamic and functional benefits for inoperable patients. The rationale is to open obstructed vessels or widen stenotic lesions using a catheter-based intervention. The procedure consists of the identification of pulmonary artery lesions that can be treated; passage of a guide wire across the lesion or occlusion; and balloon dilatation of the target lesions to restore pulmonary blood flow. Staged procedures with repeat catheterisations and dilatations are needed to achieve optimal haemodynamic results. Long-term haemodynamic and clinical follow-up are essential.
