Gross, histologic and ultrastructural studies were made of 14 porcine valve bioprostheses
that were found to contain calcific deposits at the time of removal either at reoperation (13 …

Calcification of cardiovascular prosthetic implants is a common and important problem. This
review provides an update based upon the Conference on Cardiovascular Implant …

To determine the incidence and extent of calcification of implanted glutaraldehyde-treated
porcine prosthetic heart valves, 82 valves explanted from 73 patients were examined for …

Calcification of bioprosthetic heart valves fabricated from glutaraldehyde-pretreated bovine
pericardium has not been investigated. The objectives of this study were to characterize …

Calcification, the major cause of bioprosthetic heart valve failures, is a serious clinical
problem with uncertain pathogenesis. The objectives of the present study were to define the …

Sixty-seven glutaraldehyde-processed porcine bioprostheses (PBs), recovered at autopsy or
reoperation from 65 patients, were evaluated by roentgenologic and pathologic …

Objective: Calcification is the most important cause of structural deterioration of
glutaraldehyde-fixed bioprosthetic valves. Devitalization of tissue favors calcium deposits in …

Calcification developed in the degenerating collagen of the cusps of three porcine xenograft
heart valves implanted in children for less than 4 years. The morphologic features and …

To study the process of calcification in bioprostheses, 108 glutaraldehyde-treated porcine
aortic valve leaflets were implanted subcutaneously in rabbits and removed 1 day to 6 …

The purpose of this study was to characterize the physicochemical properties of calcific
deposits that cause the failure of tissue‐derived heart valve bioprostheses. This was done in …
