Evaluation of the OpSens OptoWire III and Novel TAVR Algorithm to Measure Pressure Gradient During TAVR.

Background: We aim to establish the degree of agreement related to gradient measurement during transcatheter aortic valve replacement (TAVR) between the OpSens OptoWire III and its new proprietary TAVR algorithm and hemodynamic value derived by catheterization and echocardiogram (transthoracic echocardiogram and transesophageal echocardiogram).

Methods: The current study was a prospective, single-arm, single-center study. All subjects underwent hemodynamic assessment before and after TAVR using standard hemodynamic assessment using 2 pigtails, transthoracic echocardiogram, transesophageal echocardiogram, and the OpSens OptoWire III.
