A variety of patch materials has been used to close large atrial septal defects (ASD). Autologous pericardium and glutaraldehyde-preserved bovine pericardium are the most used. Lyophilized bovine pericardium has not been tested inside the cardiovascular system. The aim of this work was to study the behaviour and effectiveness of lyophilized glutaraldehyde-preserved bovine pericardium in ASD clo...

BackgroundAnimal-derived pericardium is a key material that enables the successful clinical use of bioprosthetic heart valves. Recently, transcatheter valves have placed more emphasis on enhancement this tissue, especially in terms producing uniform, thin, durable tissue. In study, we provide new method to achieve thinner tissue and insights into how consistent which potentially may lead valves...

The use of graft materials in bladder mucosa has been examined in animal models, but debate exists over which materials are effective. Intestine has been used as a substitute in augmentation cystoplasty for patients with neuropathic bladder, but serious adverse effects of the operation have occurred in some instances. We report a case of a successful repair of an enterovesical fistula by use of...

Rupture of the left ventricular wall after mitral valve replacement is an infrequent but lethal complication. Reporting correction technique of ventricular rupture with bovine pericardium patch secured with glue and without suturing: a 51 years-old female patient, with double rheumatic mitral lesion, severe stenosis and discrete insufficiency, who had a mitral valve replacement. During surgery,...

Methods The various xenogeneic tissues (porcine pericardium, aortic valve, aortic wall and bovine pericardium, aortic valve, aortic wall) were fixed in 0.5% glutaraldehyde solution and implanted into the subcutaneous tissue of the wild type-mouse and the KO mouse for 3 months. The implanted mice were harvested and studied for the histopathology, amounts of calcification and immune responses by ...

OBJECTIVE The objective was to analyze the decellularization process with SDS in glutaraldehyde-preserved bovine pericardium as an anticalcification method in a circulatory sheep model. METHODS The valved tubs were implanted in pulmonary artery position in sheep by 180 days. The animals were divided in two groups of 8 animals: control group--glutaraldehyde-preserved bovine pericardium and the...

Introduction: In this paper, our objective was to compare the decellularized and conventional pericardium mechanical resistance and also its capability of inducing inflammatory response in an animal experimental model. Methods: In order to study these properties, we divided the pericardia into two groups: Group I pericardium conventionally treated with GTA and Group II – pericardium previously ...
