Interventional Therapies and Mechanical Circulatory Support for Acute Pulmonary Embolism.

Overview

Acute pulmonary embolism (PE) represents the third leading cause of cardiovascular mortality, with most PE-related mortality associated with acute right ventricular (RV) failure. Despite an increase in attention to acute PE with new endovascular devices for therapy and the adoption of multidisciplinary clinical treatment teams, mortality rates remain high in patients who present with PE-related hemodynamic compromise. Currently, the advanced treatment modalities for acute high-risk and intermediate high-risk PE are limited to several interventional modalities-open surgical embolectomy and systemic fibrinolytic agents. The purpose of this state-of-the-art review is to describe modern therapeutic techniques and strategies (both interventional and surgical) and the role of mechanical circulatory support (MCS) for hemodynamic compromise in PE.
