Dual Admittance Catheter‐Derived Biventricular Pressure‐Volume Analysis in Swine: Comparison with Contrast‐Enhanced Computed Tomography During Transient Pressure Overload

Abstract

Objective Admittance catheter‐derived pressure‐volume (PV) analysis offers the ability to assess dynamic changes in ventricular performance. The present study was designed to evaluate the feasibility and accuracy of biventricular PV analysis by comparing admittance catheter‐derived measurements of left (LV) and right ventricular (RV) volumes with data obtained from simultaneous contrast‐enhanced cardiac computed tomography (CT) before, during, …
