Off-pump coronary surgery through mini-incisions: is it reasonable?

Area of Science:

• Cardiovascular Surgery
• Minimally Invasive Cardiac Surgery

Background:

• Coronary artery bypass grafting (CABG) is the gold standard for coronary revascularization but carries risks, especially for patients with comorbidities.
• Minimally invasive techniques, including off-pump surgery without sternotomy, aim to reduce these complications.

Purpose of the Study:

• To describe a novel minimally invasive off-pump CABG technique.
• To review current literature on the safety and outcomes of minimally invasive off-pump CABG.

Main Methods:

• Literature review of recent studies on off-pump coronary artery bypass grafting.
• Description of a specific minimally invasive surgical technique.

Main Results:

• Off-pump and on-pump CABG demonstrate similar revascularization completeness, long-term patency, and need for reintervention in experienced centers.
• Observational studies suggest off-pump CABG may reduce stroke, bleeding, renal complications, and mortality in high-risk patients.

Conclusions:

• Off-pump cardiac surgery without sternotomy is a viable extension of off-pump CABG, potentially as safe as conventional CABG.
• This approach may benefit high-risk patients and those requiring a faster return to demanding physical work.
