Small caliber vascular grafts for coronary artery bypass grafting have largely failed, prompting a review of current challenges, new technologies, and future possibilities for alternative conduits.
This review highlights the historical failures, current challenges, and future technological possibilities for using vascular prostheses in CABG when autologous grafts are unavailable.
Autologous grafts remain first-line for CABG; leaves open development of viable small-caliber alternatives.
Alternative conduits must be chosen when autologous grafts are not available for coronary artery bypass grafting (CABG). Viable grafts do not always have perfect characteristics for CABG, and homologous venous conduits have been used with unsatisfactory results. Many small caliber vascular grafts used for coronary bypass conduits have been developed in the past, but most of them have failed except in rare instances. In this paper the current problems in available conduits, new technologies for improvement, animal models, and possibilities for the future for CABG conduits are discussed.
