Abstract
The aim of this study is to summarize currently available catheter-based therapies in acute and chronic pulmonary embolic disease. Catheter-based therapies to treat acute pulmonary embolism and its sequelae such as chronic thromboembolic pulmonary hypertension (CTEPH) are emerging as the next frontier within interventional cardiology. However, the true benefit of these catheter-based therapies in intermediate-risk and high-risk pulmonary embolism and CTEPH remains unclear. The current evidence supporting such interventions comes primarily from small single-arm studies in acute pulmonary embolism and case series in CTEPH. Appropriately powered randomized controlled trials with meaningful clinical outcomes as endpoints are needed to elucidate the true benefit of catheter-based therapies in pulmonary embolism compared with other treatment modalities such as anticoagulation and systemic thrombolysis in acute pulmonary embolism and riociguat and pulmonary endarterectomy in CTEPH.
