Abstract
Dual sensor system for continuous blood pressure monitoring during transcatheter heart valve therapies (TVT), such as transcatheter aortic valve replacement (TAVR) or transcatheter mitral valve replacement (TMVR), comprises a controller, a support guidewire for TVT containing a first Fabry-Pérot (FP) optical pressure sensor near its distal end, and a pigtail catheter for delivery of contrast medium containing a second FP optical pressure sensor near its distal end. For example, for TAVR, the support guidewire is positioned to place the first optical pressure sensor within the left ventricle (LV) for monitoring LV pressure, the pigtail catheter is positioned in the aorta to place the second optical pressure sensor in the ascending aorta for direct measurement of pressure in the aorta, downstream of the aortic valve, enabling continuous monitoring of blood pressure at both sensor locations during TAVR. The controller may be configured to interface with standard patient monitoring systems.
