Internal thoracic artery grafts for the entire heart at a mean of 12 years.

Background: There is consensus today that the long-term results of bypassing the left anterior descending artery with an internal thoracic artery (ITA) graft are superior to those of a saphenous vein graft. Our hypothesis for this study was that three-vessel revascularization with only ITA grafts would also give excellent results.

Methods: Using our previously described techniques to enhance the length of ITA grafts by skeletonization and high mediastinal mobilization, we were able to perform tension-free, three-vessel revascularization using only ITA grafts in 125 (83%) of a consecutive series of 150 patients with three-vessel occlusive coronary disease.

Novel vascular endothelial growth factor binding domains of fibronectin enhance vascular endothelial growth factor biological activity.

Interactions between integrins and growth factor receptors play a critical role in the development and healing of the vasculature. This study mapped two binding domains on fibronectin (FN) that modulate the activity of the angiogenic factor, vascular endothelial growth factor (VEGF). Using solid-phase assays and surface plasmon resonance analysis, we identified two novel VEGF binding domains within the N- and C-terminus of the FN molecule.
