Invasive Hemodynamic Assessment of Patients with Heart Failure and Pulmonary Hypertension.

Overview

OPINION STATEMENT: Right heart catheterization (RHC) with a pulmonary artery (PA) catheter is a minimally invasive method of obtaining hemodynamic data (e.g., right atrial and pulmonary pressures, cardiac output, pulmonary vascular resistance), which are used to diagnose and manage patients with advanced heart failure (HF), HF with preserved ejection fraction, and pulmonary hypertension (PH). Invasive hemodynamic data obtained from RHC can aid in the prognostication of HF and PH patients and are important in guiding decisions of implanting mechanical circulatory support devices and listing patients for heart and/or lung transplantation. The basis of RHC has also paved the way for implantable hemodynamic devices to monitor pulmonary artery pressures in the outpatient setting, which can reduce rates of HF-related hospitalizations. We will discuss the utility of PA catheters in the diagnosis and management of the aforementioned disease states, the role of implantable hemodynamic monitors, and the complications associated with RHC procedures.
