Robotically assisted coronary artery bypass grafting: a systematic review and meta-analysis

Area of Science:

• Cardiovascular Surgery
• Minimally Invasive Surgery
• Medical Technology

Background:

• The comparative efficacy of robotically assisted coronary bypass surgery (RACBS) versus traditional non-robotic procedures remains unclear.
• Uncertainty exists regarding the superiority of RACBS in clinical outcomes.

Purpose of the Study:

• To systematically review and synthesize existing evidence comparing RACBS with non-robotic coronary bypass surgery.
• To evaluate the safety and effectiveness of RACBS based on available trial data.

Main Methods:

• Comprehensive literature searches were performed using MEDLINE, EMBASE, and LILACS databases.
• Two independent reviewers screened citations, assessed the quality of included trials, and extracted relevant data.

Main Results:

• Three non-randomized trials met the inclusion criteria.
• RACBS was linked to longer operative times but shorter ICU and hospital stays, higher extubation rates, and reduced odds of atrial fibrillation and myocardial infarction.
• No significant differences were observed in the odds of stroke or mortality between RACBS and non-robotic approaches.

Conclusions:

• While RACBS demonstrates potential benefits, the current evidence is derived from studies with inadequate design and a high risk of selection bias.
• Further high-quality randomized controlled trials are essential to validate these findings and ascertain the long-term advantages of RACBS.
