Internal mammary artery graft: retrospective report with 17 years' survival.

This report describes one of the earliest cases of successful internal mammary artery grafting. A left internal mammary-right coronary artery titanium stent anastomosis was performed on Jan. 5, 1968, at Allegheny General Hospital. Repeated cardiac catheterization 2 weeks, 6 months, and 6 years after the operation showed a patent anastomosis. The patient survived over 17 years after the operation.
