Redo coronary artery bypass graft (redo CABG) procedures are a surgical challenge, especially when one or both internal thoracic arteries (ITAs) have been previously harvested. The lack of available ITA grafts at reoperation might jeopardize the long-term outcomes, because pedicle ITAs have shown longer patency than have other grafts.^1,2

Early and midterm results after recycling of ITA grafts in coronary reoperations were demonstrated to be satisfactory.^3–5 We report clinical and angiographic long-term follow-up of this procedure.

Patients and Methods

From January 1990 to December 2005, 9 patients (7 men and 2 women) underwent redo CABG, recycling the previously implanted ITAs. Patients were evaluated with regard to clinical, echocardiographic, and angiographic findings. They were prospectively followed up by direct visit, echocardiography, and stress test (Table 1). Between June 2006 and December 2006, a coronary angiographic follow-up was performed in all survivors (8 patients). Outcome variables included perioperative (30-day) mortality and morbidity, long-term survival, and ITA graft patency.
