Review of minimally invasive coronary artery bypass grafting

Area of Science:

• Cardiovascular Surgery
• Minimally Invasive Techniques
• Coronary Artery Disease Management

Background:

• Coronary artery bypass grafting (CABG) is a cornerstone treatment for coronary artery disease (CAD).
• Traditional CABG involves a sternotomy, which carries potential risks and a longer recovery period.
• Minimally invasive CABG (MICABG) offers an alternative approach, avoiding full sternotomy.

Purpose of the Study:

• To provide an overview of minimally invasive CABG (MICABG) for clinicians managing patients with CAD.
• To discuss the current status, techniques, and outcomes of MICABG.
• To identify future directions and considerations for MICABG implementation.

Main Methods:

• A narrative review of existing literature on minimally invasive CABG was conducted.
• The review focused on techniques, patient selection, outcomes, and future prospects of MICABG.
• Data from observational studies and randomized controlled trials were synthesized.

Main Results:

• MICABG, particularly single-vessel procedures without cardiopulmonary bypass, has been available for over 20 years but has seen slow adoption.
• Multivessel MICABG and hybrid revascularization (MICABG combined with percutaneous coronary intervention) are options for complex CAD.
• Studies indicate MICABG is associated with lower transfusion rates, fewer infections, shorter ICU/hospital stays, and quicker return to activity.

Conclusions:

• Minimally invasive CABG represents a valuable addition to the revascularization toolkit for an aging and complex CAD population.
• Careful patient selection and preoperative planning are crucial for successful MICABG outcomes.
• Further research and evidence are needed to fully elucidate the long-term benefits and expand the application of MICABG.
