Area of Science:

  • Medical Imaging
  • Surgical Navigation
  • Cardiology

Background:

  • Pericardial puncture is crucial for draining pathological pericardial effusions.
  • Accurate needle guidance in the mobile cardiac environment is challenging.
  • Surgeon's mental visualization limits precision in soft-tissue procedures.

Purpose of the Study:

  • To develop and validate CASPER, a navigation software for pericardial puncture.
  • To enhance surgeon's understanding of effusion anatomy and guide needle trajectory.
  • To assess the feasibility and safety of CASPER in preclinical and clinical settings.

Main Methods:

  • CASPER utilizes optical localization and echographic imaging for real-time guidance.
  • Surgeons segment effusion images and define needle trajectories.
