Abstract

The first clinical use of homograft tissue in cardiovascular surgery was in 1948, when Gross used cadaveric arterial grafts to construct systemic to pulmonary artery shunts in patients with tetralogy of Fallot, and to repair coarctation of the aorta. Eighteen years later, a valved homograft was used for the first time in the treatment of congenital heart disease for reconstruction of the right ventricular outflow tract in a child with pulmonary atresia. Since these pioneering advances, valve and vascular homografts have become central to the management of congenital anomalies of the heart and great vessels. The primary use for homografts in congenital heart surgery today is establishment of a valved connection between the right ventricle and pulmonary arteries in children with tetralogy of Fallot with pulmonary atresia or other complicating factors, truncus arteriosus, transposition complexes, and double-outlet right ventricle, and in patients undergoing the Ross procedure. Homograft reconstruction of the left ventricular outflow tract has also been performed for many years in children with aortic insufficiency or recurrent aortic stenosis, but early homograft degeneration in young children has been a significant problem.

Birth Defects

Birth defects encompass structural and functional alterations that occur during embryonic or fetal development and are present since birth. The cause may be genetic, environmental or unknown and can result in physical and/or mental impairment. Here is the latest research on birth defects.

Allogenic & Autologous Therapies

Allogenic therapies are generated in large batches from unrelated donor tissues such as bone marrow. In contrast, autologous therapies are manufactures as a single lot from the patient being treated. Here is the latest research on allogenic and autologous therapies.

Aortic Coarctation

Aortic coarctation is a congenital condition characterized by narrowing of the aorta. Discover the latest research on this disease here.
