Key result
Catheter-directed therapies relieve RV strain with lower bleeding risk than systemic thrombolysis in intermediate-high-risk PE.
Why the study?
As catheter-directed therapy gains adoption in pulmonary embolism management, further studies and clinical trials are required to clearly define its role in reducing complications and mortality, especially in intermediate-high-risk patients.
Does catheter-directed therapy improve outcomes and reduce bleeding risk compared to systemic thrombolysis in patients with pulmonary embolism?
Does catheter-directed therapy improve outcomes and reduce bleeding risk compared to systemic thrombolysis in patients with pulmonary embolism?
Catheter-directed therapy is an increasingly relevant treatment for pulmonary embolism that may offer a safer alternative to systemic thrombolysis, particularly when managed by specialized response teams.
May inform PE response team decisions on catheter-directed approaches; leaves open randomized confirmation of outcome benefits.
Pulmonary embolism (PE) ranks as the third leading cause of cardiovascular-related deaths in Western nations. Patients classified as high-risk (HR)-those exhibiting hemodynamic instability-require immediate interventions to restore blood flow. While intermediate-HR (IHR) individuals remain hemodynamically stable, they face a significant chance of clinical decline and thus need close and continuous observation. Effective risk assessment, mortality prediction, and therapeutic decision-making in these patients rely on a combination of clinical evaluation and imaging studies. Catheter-directed therapy (CDT) has emerged as a promising option, offering the ability to alleviate clot burden and reduce strain on the right ventricle, all while posing a lower risk of major bleeding compared to systemic thrombolysis. The growing adoption of CDT reflects its increasing relevance in PE treatment, especially when managed by specialized PE response teams that ensure individualized, multidisciplinary care. As clinical practices evolve, further studies and robust clinical trials are necessary to clearly define CDT's role in lowering the risks of complications and death among IHR PE patients. This article explores the current understanding and future direction of managing PE, focusing in the role of catheter-based interventions.

Latsios et al. (2025) conducted a review in Pulmonary embolism. Catheter-directed therapy vs. Systemic thrombolysis was evaluated. Catheter-directed therapies offer effective clot reduction and right ventricular strain relief with lower bleeding risks than systemic thrombolysis in intermediate-high-risk pulmonary embolism.
