Human cardiac valves are increasingly used in the reconstruction of ventricular outflow tracts and offer performance advantages over porcine and mechanical prostheses; the durability of these replacements has been associated with leaflet interstitial

Cryopreserved allograft valves are increasingly being used as valvular replacements. Leaflet fibroblast viability has been suggested to influence clinical durability. The warm ischemic time is thought to be a critical determinant of this cell viabili

Background. Surgical correction of symptomatic Zenker's diverticulum is effective; however, elderly symptomatic patients may be denied surgical intervention because of perceived increased risks. Methods. To address this concern, we reviewed 75 patien

Parathyroid carcinoma is a rare clinical entity with a reported incidence of between 0.5% and 4% of all patients with primary hyperparathyroidism. Equally as unusual is the presence of an intrathyroidal parathyroid gland, which is usually found at th

Preparation protocols for human cardiac valves are intended to minimize cytotoxicity because it has been thought that viable leaflet interstitial cells may enhance homograft durability. Preimplantation factors influencing the status of these cells at

To assess the initial metabolic phase of cellular injury from cardiac valve processing, high-energy phosphate concentrations were analyzed in valve leaflets subsequent to critical processing steps. Using a porcine model, valves were processed in a ma

Twenty-five human cryopreserved valves with harvest-related warm ischemic times (WITs) ranging from 0 to 20 hours were studied using transmission electron microscopy to characterize the effects of harvesting and preservation on leaflet matrix cells.

Preimplantation preparation of cardiac valves includes three major steps: (1) harvesting with accompanying ischemia (warm time from cessation of donor heart beat), (2) antibiotic disinfection, and (3) controlled-rate cryopreservation. To define the i
