BACKGROUND Endothelial cell seeding of glutardialdehyde-fixed biological heart valves is hypothesized to improve biocompatibility and durability; however, the toxicity of glutardialdehyde prevents its use as a biological coating. Therefore, different detoxification strategies are applied, including surface coating with titanium, before in vitro endothelialization of glutaraldehyde-fixed bovine ...

introduction the pericardial agenesis is a rare congenital anomaly. classified as partial or total being asymptomatic in most cases, but some patients are at risk for serious complications and death, and these have indication for surgical treatment. case presentation this paper describes the case of a 21 year old patient, with atypical precordial pain, diagnosed with agenesis of the left perica...

The aim of this investigation was to evaluate the use of polypropylene mesh and glycerol preserved bovine pericardium (GBP) to repaire abdominal wall defects in 24 clinically healthy mongrel dogs using inlay and underlay techniques. Twenty four healthy mongrel dogs were used in this study. The animals were divided into two main groups according to the type of the prosthetic material used. Each ...

Decellularization techniques have been developed in an attempt to reduce the antigenicity of xenogeneic biomaterials, a critical barrier in their use as tissue engineering scaffolds. However, numerous studies have demonstrated inadequate removal and subsequent persistence of antigens in the biomaterial following decellularization, resulting in an immune response upon implantation. Thus, methods...

OBJECTIVE To analyze the results of 125 carotid endarterectomies under loco-regional anesthesia, with selective use of shunt and bovine pericardium patch. METHODS One hundred and seventeen patients with stenosis ≥ 70% in the internal carotid artery on duplex-scan + arteriography or magnetic resonance angiography underwent 125 carotid endarterectomies. Intraoperative pharmacological cerebral p...

BACKGROUND In this study we evaluated the performance of bovine pericardium preserved in glutaraldehyde used as a vascular patch. METHODS Fourteen young pigs, six females and eight males, weighting 10.3 - 18.4 kg were used in our study. We implanted three remnants in each pig, two in the abdominal aorta and one was juxtaposed to the peritoneum. The smooth face (SF) and rough face (RF) of each...

INTRODUCTION The aim of this study was to clinically assess the capacity of a novel bovine pericardium based, non-cross linked collagen matrix in root coverage. METHODS 62 gingival recessions of Miller class I or II were treated. The matrix was adapted underneath a coronal repositioned split thickness flap. Clinical values were assessed at baseline and after six months. RESULTS The mean rec...
