Influence of Graft/Host Diameter Ratio on the Hemodynamics in Sequential ITA Anastomoses

Abstract Multivessel grafting with internal thoracic artery (ITA) conduits may improve the long-term results of coronary surgery for patients with multivessel coronary disease. Sequential ITA grafting has been increasingly used as a means of allowing a single ITA to revascularize a greater amount of the myocardium (Izzat et al, 1994). In this procedure, the graft first supplies blood to a coronary artery via a side-to-side …
