Systems, methods, and devices for cardiac procedures with a multi-pressure measurement catheter

A method to perform multiple diagnostic functions using a catheter with a multi-pressure measurement pathway arrangement, the method comprising:

• measuring a left ventricular pressure with an end hole of a central pressure measurement pathway, the central pressure measurement pathway formed by a central tube being at least partly disposed within the catheter and terminating at a first hub to connect the end hole of the central pressure measurement pathway to a pressure transducer, the end hole of the central pressure measurement pathway being located at a distal end of the catheter;
• and
• measuring an aortic pressure with one or more end holes of one or more outer pressure measurement pathway, the one or more outer pressure measurement pathway formed by an outer tube surrounding the central tube and disposed in the catheter, the one or more outer pressure measurement pathway terminating at a second hub to connect one or more end holes of the one or more outer pressure measurement pathway to a pressure transducer, the one or more end holes being located along an outer sidewall of the catheter spaced one or more defined distances from the end hole of the central pressure measurement pathway.
