Aorta-coronary bypass grafting with the internal mammary artery: clinical experience in 70 patients
C Chenvechai, MJ Irarrazaval, FD Loop, DB Effler, G Rincon and FM Sones Jr
Clincal and angiographic results in 70 patients who received free internal
mammary artery (IMA) grafts are reviewed. One postoperative death occurred,
but it was not related to the free IMA technique. Forty- seven patients
underwent postoperative arteriography. The average interval between
operation and catheterization was 10.7 months, and the patency rate for 49
free IMA grafts was 89.8 per cent. Of the 29 patients who recieved free IMA
grafts as the only revascularization procedure, 21 patients (80 per cent)
progressed to Functional Class I and only 5 patients did not have
improvement in their functional status.
