“…In vivo results of the grafts made up of these classic materials, particularly low flow grafts are not encouraging. Some reports have shown that the human umbilical vein can be used as a biological graft with patency rates of 46% between 3— 13 months [ 54 ]. Along the same line Vrandecic et al has used a Bovine Internal Mammary Artery (BIMA) graft in the surgical treatment of small arteries [ 55 ].…”

Three-dimensional (3D) printing, also known as additive manufacturing, was developed originally for engineering applications. Since its early advancements, there has been a relentless development in enthusiasm for this innovation in biomedical research. It allows for the fabrication of structures with both complex geometries and heterogeneous material properties. Tissue engineering using 3D bio-printers can overcome the limitations of traditional tissue engineering methods. It can match the complexity and cellular microenvironment of human organs and tissues, which drives much of the interest in this technique. However, most of the preliminary evaluations of 3Dprinted tissues and organ engineering, including cardiac tissue, relies extensively on the lessons learned from traditional tissue engineering. In many early examples, the final printed structures were found to be no better than tissues developed using traditional tissue engineering methods. This highlights the fact that 3D bio-printing of human tissue is still very much in its infancy and more work needs to be done to realise its full potential. This can be achieved through interdisciplinary collaboration between engineers, biomaterial scientists and molecular cell biologists. This review highlights current advancements and future prospects for 3D bio-printing in engineering ex vivo cardiac tissue and associated vasculature, such as coronary arteries. In this context, the role of biomaterials for hydrogel matrices and choice of cells are discussed. 3D bio-printing has the potential to advance current research significantly and support the development of novel therapeutics which can improve the therapeutic outcomes of patients suffering fatal cardiovascular pathologies.

During the last decade many countries have witnessed a dramatic increase in the number of patients undergoing coronary artery bypass grafting. As a consequence, the number of patients with insufficient or inadequate autologous vessels suitable for use as coronary artery grafts is also increasing. These patients may include those who have had previous heart operations, as well as those with bilateral varicose veins and phlebectomy. Given the shortage of autologous grafts, prosthetic and biological conduits are available for use in CABG. However, a small-diameter vascular prosthesis with acceptable long-term patency still remains the cherished wish for cardiovascular surgeons.

“…Like some other artificial small-diameter vascular grafts showing excellent anti-thrombogenicity in in vitro studies, no longterm results or patencies have been reported so far for their use in CABG. A human umbilical vein (HUV) graft (Biograft, Meadox Medicals, Oakland, NJ, USA; 4 mm internal diameter) demonstrated angiographic graft patency rates of 46% (6/13) at 3-13 months [19]. In another report, treated bovine IMA graft (Biocor BIMA Biograft, Biocor laboratory, 4 and 5 mm of internal diameter) was implanted in the coronary artery position of 20 patients [20].…”

Prosthetic grafts are required for coronary artery bypass grafting (CABG) when the availability of suitable autologous conduits is limited. The ideal cardiovascular bypass graft requires a broad range of characteristics including strength, viscoelasticity, biocompatibility, blood compatibility and biostability. Many alternative conduits have been developed and used in the past, but most of them have failed, except in rare instances. This review aims to analyse the current status of their use and prospects for the future. We performed a literature search on PubMed using the generic terms 'conduits for coronary artery bypass grafting'; 'reoperative coronary artery bypass grafting'; 'redo coronary artery bypass grafting'; 'PTFE'; 'Dacron or PET'; 'gastroepiploic artery'; 'inferior epigastric artery'; 'biological grafts'; 'tissue-engineered grafts'; 'synthetic grafts'; 'prosthetic grafts'; 'polyurethane grafts'; 'cephalic veins'; 'short saphenous vein;' and 'alternative conduits'. In addition, we searched through related citations and references from selected articles. A total of 1253 references and 110 full-text articles were reviewed, and they were further selected based on available information. This review concludes that, over the past three to four decades, achieving the goal of a prosthetic graft with equivalent function and durability to the internal mammary artery or long saphenous vein has proved to be elusive.
