Future perspectives in catheter-based treatment of pulmonary embolism

Abstract

AbstractPulmonary embolism is the third commonest cause of cardiovascular death globally. The majority of such patients present with low-risk features and can be managed with simple anticoagulation; however, a large group of patients exhibit evidence of right ventricular dysfunction on echocardiography or CT at the time of presentation and these patients are at risk of early haemodynamic compromise, particularly in those with abnormal cardiac biomarkers. Catheter-directed thrombolysis has been proposed as a treatment-strategy for patients with pulmonary embolism with evidence of acute right ventricular dysfunction. We review the current technologies in mainstream use, the evidence base in support of their use and discuss future research requirements in this area.
