Abstract

Described herein is a guide wire that includes one, two or multiple pressure transducers for use in TAVI. The guide wire may include an aortic pressure sensor spaced from a left ventricular pressure sensor with sufficient length to allow the aortic pressure sensor to be located in the aorta while the ventricular pressure sensor is simultaneously located in the left ventricle. The pressure readings between the left ventricle and aorta may be subtracted to determine an improved indication of the prognosis of a patient with intermediate post-TAVR aortic regurgitation after assessment with transesophageal echocardiography.

Description

Technical field [0001] The present invention relates to a guide wire for sensing pressure and a method of use thereof. Background technique [0002] All publications cited herein are incorporated by reference in their entirety, as if each individual publication or patent application was explicitly and individually indicated as being incorporated by reference. The following description includes information that can be used to understand the present invention. It is not admitted that any information provided in this article is prior art, or is related to the present invention as currently claimed, or that any publication cited explicitly or implicitly is prior art. [0003] Transesophageal echocardiography (TEE) is currently the mode of choice in the comprehensive preoperative evaluation of aortic regurgitation (AR) after TAVR, and it can evaluate both the severity and the mechanism of action, thereby combining the valve with the paravalvular (PV ) AR is distinguished. It has been...
