A system for tracking and displaying a real-time catheter position overlaying a fluoroscopic image includes a catheter having an optical coherence tomography (OCT) sensor thereon, a displacement sensor configured to identify displacement of the catheter, a controller, and a display. The controller is configured to receive a fluoroscopic image of the distal end of the catheter at a first position and determine a displacement of the catheter from the first position to a second position using the displacement sensor. The display is configured to display the distal end of catheter at the second position as an overlay on the fluoroscopic image.
