NCT02737969

Brief Summary

This is a pilot study of patients undergoing structural heart disease procedures that utilize TEE and fluoroscopic guidance at the New York University (NYU) Langone Medical Center. Patients in this study will undergo their procedure utilizing the TEE/Angio fusion software prototype. This protocol is primarily intended to ascertain the potential utility of the software prototype in the study population and to provide data and feedback to improve the workflow and algorithms of the prototype. As such, a primary outcome variable and statistical analysis plan have not been identified. However, procedural time, measures of radiation exposure (dose area product, total radiation dose, fluoroscopy time), degree of residual valvular regurgitation or paravalvular regurgitation as applicable, and complications will be recorded.

Outcome Measures

Primary Outcomes (5)

  • Procedural Time'

    One day

  • Dose Area Product of Radiation Exposure

    Once the TEE probe is placed, the interventional cardiologist will acquire 2 fluoroscopic images with the 'tee probe in view, at least 30 degrees apart. These 2 images will be used to co-register the ultrasound and fluoroscopy systems. The document entitled, "NSR\_EchoXrayFusion", this adds a negligible amount of radiation exposure (0.0006%).

    One day

  • Degree of residual valvular or paravalvular regurgitation

    One day

  • Total Radiation Dose

    One Day

  • Fluoroscopy Time

    One Day

Study Arms (1)

TEE/Angio fusion software

Patients planned to undergo a transcatheter-based structural heart disease procedure that utilizes TEE and fluoroscopic guidance

Device: Transesophageal Echocardiography/angiography (TEE/Angio)

Interventions

The TEE probe will be inserted into the patient's esophagus, after anesthetic induction or conscious sedation is administered, and removed after the completion of the procedure. Once the TEE probe is placed, the interventional cardiologist will acquire 2 fluoroscopic images with the TEE probe. These images will be used to co-register the ultrasound and fluoroscopy systems. As part of routine care, TEE and fluoroscopy images will be acquired throughout the procedure for clinical purposes. As new fluoroscopy images are acquired, the prototype software will automatically track the location of the TEE probe. When the echocardiographer has an image of a cardiac structure of interest, he may use the prototype software to place landmarks. The echocardiographer may then press a button to have the landmarks displayed on the fluoroscopy image that is only visible on an assist monitor and will not interfere with the standard fluoroscopy imaging monitor.

Study Population

Patients planned to undergo a transcatheter-based structural heart disease procedure that utilizes TEE and fluoroscopic guidance at the NYU Langone Medical Center

You may qualify if:

  • Subjects must be more than 18 years of age
  • Subjects must have a plan to undergo a transcatheter-based structural heart disease procedure that utilize TEE and fluoroscopic guidance

You may not qualify if:

  • Subjects with a known contraindication for insertion of the TEE probe (e.g. history of esophageal stricture, scleroderma, etc.), which will be ascertained by a non-invasive imaging specialist (contraindications are routinely assessed in the course of the preoperative workup)Subjects who have a known contraindication for insertion of the TEE probe (e.g. history of esophageal stricture, scleroderma, etc.), which will be ascertained by a non-invasive imaging specialist (contraindications are routinely assessed in the course of the preoperative workup)
  • Pregnant
  • Participating in a competing study
  • Unable or do not provide consent
