A Tale of Two Pulmonary Artery Catheters.

Innovative catheter-based therapies are increasingly being used for the treatment of patients with submassive pulmonary embolism. These patients may be monitored in the intensive care unit following insertion of specialized pulmonary artery catheters. However, the infusion catheters utilized in catheter-based therapies differ greatly from traditional pulmonary artery catheters designed for hemodynamic monitoring. As such, the critical care team will have to be familiar with the monitoring and management of these novel catheters. Important distinctions between the catheters are illustrated using a clinical case report.
