About the Book

Cardiovascular diseases are still the leading cause of death in developed countries. Revascularization procedures such as coronary artery and peripheral bypass grafts, as well as access surgery represent a 2$ billion market yearly for the US alone. Despite intense research over many decades, no clinically suitable, shelf-ready, synthetic, vascular, small-caliber graft exists. There is therefore still a quest for such a clinical vascular prosthesis for surgical revascularization procedures and access surgery. Many approaches have been tried and are currently under investigation with promising results. These range from acellular and cell-based, stable or bio-degradable, synthetic scaffolds to biological or decellularized grafts, not forgetting self-assembly technologies for in vitro or in vivo VTE. All these approaches can be further enhanced by functionalization, e.g. with growth factors and drug elution. This updatable book aims to cover all the relevant aspects of Vascular Tissue Engineering (VTE) and novel alternatives to develop vascular grafts for clinical applications. The chapters in this book cover different aspects of manufacturing scaffolds with various polymers, mechanical characteristics, degradation rates, decellularization techniques, cell sheet assembly, 3-D printing and autologous mandril-based VTE. All the necessary in vitro tests such as biocompatibility and thrombogenicity are reviewed. Pre-clinical assessment of in vivo experimental models include patency, compliance, intimal hyperplasia, inflammatory reaction, cellular ingrowth and remodeling. Finally, early clinical trials will be periodically updated regarding results, regulatory aspects and post-marketing quality assessment. Furthermore, the reader should get an insight into various approaches, technologies and methods to better understand the complexity of blood surface and cell interactions in VTE. Translational research has yielded early human applications clearly showing the enormous need of research in the field to provide better solutions for our patients and this continuously updated book will hopefully become a reference in the field for life sciences.

Peter Zilla's Peter Zilla is an academic Cardiovascular and Thoracic Surgeon who is Chief of Adult and Paediatric Cardiothoracic Surgery at Cape Town's Groote Schuur and Red Cross Children's Hospitals, Director of the Cardiovascular Research Unit, Co-Director of the Cape Heart Institute, and CEO of Strait Access Technologies at the University of Cape Town, South Africa. He holds an M.D. degree from the University of Vienna, a Dr.Med. degree from the University of Zurich, a Ph.D. from the University of Cape Town, and a P.D. (habil) from the University of Vienna. In his capacity as Chief of the Christiaan Barnard Department, where the first human heart transplantation was performed in 1967, he has built up a training program for cardiothoracic surgeons from the African continent.

His main research foci have consistently been in the fields of tissue engineering and prosthetic cardiovascular implants. Pioneering tissue engineering since 1983, he initiated an international multicenter study with in-vitro endothelialisation of peripheral bypass grafts culminating in more than 400 patient-implants. His second focus, improving heart valve prostheses for the young patients of developing countries, has led to tissue treatments that extend the longevity of heart valve prostheses manifold.

His engagement in the field of rheumatic heart disease has additionally awarded him international recognition as a leader in this field when he united all major cardiothoracic surgical societies worldwide under one umbrella (Cardiac Surgery Intersociety Alliance/CSIA), thereby creating a worldwide platform for the establishment of local cardiac surgical capacity in regions of the world that are endemic for RHD but have no access to open heart surgery. Addressing this challenge also from another side, he co-founded a University of Cape Town Start-Up Company in 2008 under the name "Strait Access Technologies" (SAT), securing a leading global position in innovative concepts for trans-catheter heart valve technologies for the patients and resources of lowto middle-income countries.

He is author of almost 200 peer-reviewed full papers and inventor of 41 filed or issued US/PCT patents, having been cited almost 10,000 times with an h-index of 51. He is the editor of 6 books and has authored numerous book chapters. He obtained significant international academic and industry grants and was the recipient of several international awards.
