Systems, methods, and devices for performing
heart procedures include a multi-functional
catheter with a multi-lumen arrangement. The multi-lumen arrangement includes a central lumen formed by an inner tube with multiple pressure channels embedded in the wall of the
catheter. The central lumen has a first end hole terminating at a distal end of the multi-functional
catheter. The outer lumen has one or more second side holes. Moreover, a welded tip can maintain a consistent
diameter for the distal end. Multiple radiopaque markers can identify various portions of multi-functional catheter to aid in positioning the lumens at different placements in the heart and / or crossing the
aortic valve. Accordingly, multiple diagnostic procedures can be performed with the multi-functional catheter, such as a coronary angiogram and a trans-valvular pressure gradient measurement, while omitting reliance on additional catheters or a digital console
system.
