BACKGROUND: Patients with patent grafted bilateral internal thoracic arteries may require repeat myocardial revascularization because of either progression of disease in a nongrafted native vessel or failure of a saphenous vein graft. In order to avoid extensive dissection and possible damage of the internal thoracic arteries, we elected to proceed with an off-pump minimally invasive direct coronary artery bypass grafting (MIDCABG) approach using the pedicled right gastroepiploic artery. This paper summarizes our midterm angiographic results.

METHODS: From 1996 to 2003, 15 patients were reoperated on using this approach in our department. Internal thoracic artery grafts always revascularized the anterior and lateral territories and were angiographically patent. Indications for repeated surgery were: (1) coronary disease progression in 8 patients; (2) occlusion of the saphenous vein graft in 6 patients; and (3) anastomotic stenosis of a pedicled right gastroepiploic artery in 1 patient. Off-pump grafting of the pedicled right gastroepiploic artery was targeted at the posterior descending artery in 14 patients, and at the left anterior descending artery in 1 patient.

RESULTS: Thirty-day mortality was 6.5% (1 of 15 patients). With a mean follow-up of 56 ± 20 months, angina-free survival was 79%. At angiographic control (mean, 38 months), the pedicled right gastroepiploic artery was patent in 13 patients. One patient had an occluded right gastroepiploic artery graft at 23 months and another patient showed progression of disease distal to the right gastroepiploic artery anastomosis at 28 months.

CONCLUSIONS: Off-pump MIDCABG repeat revascularization with a pedicled right gastroepiploic artery is an effective method of revascularization for patients with patent bilateral internal thoracic arteries.
