Coronary artery bypass grafting without full sternotomy

Area of Science:

• Cardiovascular Surgery
• Minimally Invasive Cardiac Surgery

Background:

• Coronary artery bypass grafting (CABG) is a standard treatment for coronary artery disease.
• Traditional CABG involves a full sternotomy, which can lead to significant patient morbidity.
• Minimally invasive techniques aim to reduce surgical trauma and improve patient recovery.

Purpose of the Study:

• To review minimally invasive coronary artery bypass grafting techniques.
• To highlight the efficacy and safety of alternative approaches to full sternotomy CABG.

Main Methods:

• Review of established minimally invasive CABG procedures, including Left Internal Thoracic Artery-Left Anterior Descending artery bypass (LITA-LAD bypass) via left anterior thoracotomy.
• Discussion of techniques for multiple revascularizations using limited lateral thoracotomy or L-figure approaches.
• Exploration of alternative bypass methods such as axillary-coronary bypass and Right Gastroepiploic Artery-Right Coronary Artery bypass (RGEA-RCA bypass), particularly for redo surgery.

Main Results:

• LITA-LAD bypass is a well-established procedure with good graft patency, low mortality, and morbidity rates.
• Multiple revascularizations can be achieved through limited thoracotomy or L-figure approaches.
• Axillary-coronary and RGEA-RCA bypasses serve as viable alternatives in specific patient populations, including redo cases.

Conclusions:

• Minimally invasive CABG, including LITA-LAD bypass, provides a less invasive option for selected patients.
• Alternative surgical strategies exist for complex and redo coronary artery bypass grafting procedures.
