Official title

artifiCiAl Intelligence Model for Evaluating the Surgical Techniques of caRdiAc Surgeons (CAMERA)

Overview

The goal of this study aims to investigate the use of artificial intelligence to analyze and evaluate the characteristics and proficiency of surgeons during vascular anastomosis in coronary artery bypass grafting (CABG) procedures. The main question it aims to answer is: Consistency assessment between AI evaluation scores and human expert evaluation scores for surgeons during left anterior descending (LAD) artery anastomosis.

Primary outcome measures

  • Consistency assessment between AI surgical evaluation scores and human expert scores. [Time frame: At the end of enrollment]
Secondary outcome measures (3)
  • Intraoperative measurement of graft flow and flow resistance. [Time frame: After enrollment]
  • Characteristics of the surgeon's motion trajectory. [Time frame: After enrollment]
  • Consistency assessment between AI surgical evaluation scores levels and human expert scores levels. [Time frame: After enrollment]

Eligibility criteria

Inclusion criteria

  • Age ≥ 18 years
  • Undergoing internal mammary artery-to-left anterior descending artery bypass grafting
  • First-time recipient of isolated CABG surgery
  • Signed written informed consent

Exclusion criteria

  • Patients with acute coronary syndrome
  • Patients with contraindications to coronary CT angiography or coronary angiography
  • Patients with renal insufficiency or active liver disease, including those with persistently elevated serum transaminases of unknown cause or any serum transaminase levels exceeding three times the upper limit of normal.

Criteria are shown verbatim from the registry (in English). Final eligibility is always assessed by the study center.
