We fully agree with Habib that, on the basis of the current literature, radial artery patency is supposed to be superior to sapheneous vein patency even when the grafts are anastomosed to moderately stenosed coronary targets. Nevertheless, we believe that the radial artery as a graft for coronary artery bypass grafting should be used under the most promising conditions, that is, for highly stenosed coronary vessels. Radial artery harvesting is more complex than vein harvesting and may lead to more serious complications, such as circulatory or sensory disturbances at the donor arm. Considering this in a risk–benefit analysis, we argue that the radial artery should be harvested only when optimum patency rates are expected for the individual patient. Therefore, we adhere to our recommendation to place the radial artery only to highly stenosed target vessels.
