Beating heart totally endoscopic coronary artery bypass

Area of Science:

• Cardiovascular Surgery
• Minimally Invasive Techniques
• Vascular Grafting

Background:

• Graft patency and freedom from graft failure are critical outcomes in coronary artery bypass grafting.
• Beating-heart totally endoscopic coronary artery bypass (TECAB) is a minimally invasive approach under investigation.

Purpose of the Study:

• To evaluate graft patency and clinical outcomes after beating-heart TECAB.
• To assess the safety and efficacy of TECAB in patients requiring coronary revascularization.

Main Methods:

• 214 patients underwent beating-heart TECAB between July 2004 and June 2007.
• Postoperative angiography (CT or conventional) assessed graft patency and anastomosis.
• Clinical follow-up evaluated major adverse cardiac events.

Main Results:

• No myocardial infarction, operative mortality, or conversion to cardiopulmonary bypass was observed.
• Angiography confirmed grossly patent grafts without stenosis in all assessed patients.
• 1.4% of patients required reintervention, indicating high clinical freedom from graft failure.

Conclusions:

• Beating-heart TECAB demonstrates excellent clinical freedom from graft failure (98.6%).
• The technique shows promising short-term results for coronary revascularization.
• Long-term angiographic and clinical follow-up is warranted to confirm durability.
