[Minimally invasive coronary surgery: new developments in myocardial revascularization]

Area of Science:

• Cardiovascular Surgery
• Minimally Invasive Techniques
• Surgical Innovation

Background:

• Conventional sternotomy for coronary revascularization carries risks like bleeding and infection.
• Minimally invasive approaches aim to reduce these complications and improve patient recovery.
• Growing interest in less invasive methods for coronary artery bypass surgery.

Purpose of the Study:

• To review the evolution and benefits of minimally invasive coronary revascularization techniques.
• To highlight advancements in surgical approaches and their impact on patient outcomes.
• To discuss the role of thoracoscopy and robotics in enhancing minimally invasive cardiac surgery.

Main Methods:

• Review of existing literature on minimally invasive coronary revascularization.
• Analysis of techniques including minimally invasive direct coronary artery bypass and totally endoscopic coronary artery bypass.
• Discussion of advancements in conduit harvesting (e.g., internal mammary artery) using thoracoscopy and robotics.

Main Results:

• Minimally invasive techniques are associated with fewer perioperative complications, shorter hospital stays, and faster return to daily activities.
• Faster functional recovery and improved quality of life are potential benefits.
• Techniques are becoming increasingly personalized to patient anatomy and revascularization goals.

Conclusions:

• Minimally invasive coronary surgery is an evolving field with growing evidence supporting its benefits.
• Thoracoscopy and robotics represent promising innovations for further improving outcomes.
• Mini-invasiveness is a key trend in the advancement of coronary artery bypass surgery.
