[Myocardial revascularization. Historical review]

Area of Science:

• Cardiovascular Surgery
• Cardiac Revascularization
• Medical Device Technology

Context:

• Atherosclerotic coronary artery disease (CAD) is a leading cause of mortality in developed nations, underscoring the critical importance of effective surgical interventions.
• Historically, indirect revascularization techniques yielded suboptimal and inconsistent clinical results, prompting the development of more advanced surgical strategies.
• The evolution of surgical procedures reflects a continuous effort to improve outcomes for patients suffering from CAD.

Purpose:

• To review the historical evolution of surgical treatments for coronary artery disease (CAD).
• To evaluate the transition from indirect to direct myocardial revascularization techniques.
• To assess the safety and efficacy of various direct revascularization methods.

Summary:

• Early surgical attempts at indirect revascularization, based on questionable scientific principles, provided poor and unpredictable outcomes.
• The development of implanting the left internal mammary artery into the myocardium showed initial promise but limited success in establishing coronary connections.
• Direct myocardial revascularization, employing techniques such as patches, endarterectomies, and bypass grafts, emerged as a safer and objectively assessable approach to restore myocardial blood supply.

Impact:

• Direct myocardial revascularization techniques have demonstrated safety and allow for objective assessment of surgical outcomes.
• These advancements provide improved therapeutic options for managing atherosclerotic coronary artery disease.
• The evolution of surgical strategies continues to enhance the management of life-threatening cardiac conditions.
