[Myocardial revascularization without extracorporeal circulation].

Area of Science:

• Cardiovascular Surgery
• Interventional Cardiology

Context:

• Coronary artery disease (CAD) management involves drug therapy, percutaneous coronary angioplasty (PCI), and surgical myocardial revascularization.
• Conventional coronary artery bypass grafting (CABG) using cardiopulmonary bypass (CPB) has been the standard for decades, especially for complex CAD.
• Minimally invasive techniques and interest in off-pump coronary artery bypass (OPCAB) surgery challenge the traditional on-pump CABG approach.

Purpose:

• To review the evolution and clinical implications of OPCAB surgery.
• To compare the advantages and disadvantages of OPCAB versus on-pump CABG.
• To evaluate OPCAB as a treatment strategy for coronary artery disease.

Summary:

• OPCAB surgery, performed on a beating heart without cardiopulmonary bypass, is gaining traction as an alternative to conventional on-pump CABG.
• OPCAB may offer benefits for patients with co-morbidities contraindicating CPB use.
• Clinical outcomes and efficacy of OPCAB in the general patient population require further comprehensive evaluation.

Impact:

• Provides a comparative analysis of OPCAB and on-pump CABG from theoretical and clinical perspectives.
• Informs clinical decision-making regarding surgical revascularization strategies for coronary artery disease.
• Highlights areas for future research in OPCAB techniques and patient selection.
