CARDIAC VALVE ALLOGRAFTS (HOMOGRAFTS) highlights the current controversy about freehand subcoronary aortic valve and root replacement with regard to postoperative morbidity and long term durability. It discusses particular implantation techniques of preference in young patients and in different root pathology. Other chapters address intermediate- and long-term results on cardiac valve and vascular homografts for treating complicating cardiac valve and aortic infections.
The chapter on basic science additionally makes this book a highly authoritative reference source for cardiac surgeons, physicians and scientists.
This work provides a current survey of the state-of-the-art.
