Interval results with right gastroepiploic bypass.

Area of Science:

• Cardiovascular Surgery
• Minimally Invasive Cardiac Surgery
• Coronary Artery Bypass Grafting

Background:

• Right gastroepiploic artery bypass grafting is a recognized surgical option since the mid-1980s.
• Long-term graft patency remains a critical consideration for this procedure.
• Minimally invasive techniques have emerged to address surgical challenges.

Purpose of the Study:

• To evaluate the efficacy of off-pump, minimally invasive right gastroepiploic artery bypass grafting.
• To assess long-term graft patency and patient outcomes in a high-risk cohort.
• To analyze results in patients with reoperative coronary artery disease.

Main Methods:

• A series of 43 patients (44-79 years) underwent off-pump, minimally invasive right gastroepiploic artery bypass grafting via a subxiphoid incision.
• All patients had Canadian Cardiovascular Society class III-IV heart disease, with 81.3% having undergone 1-3 reoperations.
• Follow-up averaged 57.9 months, including Doppler studies and angiography for patency assessment.

Main Results:

• Forty-one of 43 patients (95.3%) survived at a mean follow-up of 57.4 months.
• Graft patency rates were high, with Doppler studies showing 95.3% and angiography confirming 91.6% patency.
• Postoperative complications were minimal (7%), with a crude mortality of 2.3%.

Conclusions:

• Minimally invasive, off-pump right gastroepiploic artery bypass grafting is a safe and effective option for high-risk patients with reoperative coronary artery disease.
• The procedure yields favorable long-term graft patency and low mortality rates.
• This approach provides a viable surgical choice with excellent outcomes in a challenging patient population.
