Exclusion criteria include patients with acute coronary syndrome, contraindications to coronary CT angiography or coronary angiography, and those with renal insufficiency or active liver disease. Specifically, patients with persistently elevated serum transaminases of unknown cause or those with any serum transaminase levels exceeding three times the upper limit of normal will also be excluded from the study.
Who may be able to join
- Age ≥ 18 years

About this study
Official title: artifiCiAl Intelligence Model for Evaluating the Surgical Techniques of caRdiAc Surgeons (CAMERA)
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.
What is being measured
The primary outcome is the main question the study is designed to answer.
Consistency assessment between AI surgical evaluation scores and human expert scores.
Measured: At the end of enrollment
Secondary outcomes (3)
Intraoperative measurement of graft flow and flow resistance.
Measured: After enrollment
Characteristics of the surgeon's motion trajectory.
Measured: After enrollment
Consistency assessment between AI surgical evaluation scores levels and human expert scores levels.
AI surgical evaluation scores levels were divided into the following 3 score levels: low, middle, high; human expert scores levels were divided into the following 3 score levels: low, middle, high.
Measured: After enrollment
