Procedural safety of a fully implantable intravenous prostanoid pump for pulmonary hypertension.
In patients with severe pulmonary arterial hypertension, subcutaneous or catheter-based intravenous application of prostanoids carries a risk of local side effects or systemic infections, which limits their use and acceptance. Recently, a fully implantable pump for continuous application of intravenous treprostinil was approved in Germany. However, surgery is a major risk for patients with severe pulmonary arterial hypertension. The purpose of this study was to investigate the safety of a fully implantable pump inserted under local or general anesthesia in patients with severe pulmonary hypertension. ⋯ Our observational study provides preliminary evidence supporting the procedural safety of a fully implantable pump inserted under local or general anesthesia for patients with severe pulmonary hypertension. The observation of major complications in a subset of patients requires extensive pre- and post-operative assessments. Future trials are required to provide further evidence for the long-term safety and efficacy of the pump using this approach.
