1. Oral Use of Phenytoin to Reduce Calcification in Bovine Pericardium and Porcine Aortic Leaflets Implants in Rats
Abstract Introduction: This study aims to test the effect of phenytoin as an inhibitor of the process of dystrophic calcification in bovine pericardium and porcine leaflets implanted in the subcutaneous tissue of rats. Methods: Isolated segments of biomaterials were implanted subcutaneously in young rats. The study groups received 500 mg phenytoin per kilo

2. Mortality Rates of Surgical Techniques for Correcting Atrioventricular Disjunction
Abstract We compared the mortality rates of two surgical techniques for correction of atrioventricular disjunction in 10 out of 720 patients who underwent mitral valve replacement from 2005 to 2012. In group I, the mitral annulus was fixed with bovine pericardial strips; in group II, a 'patch' of bovine pericardium was sutured and extended from the base of t

3. Correção de fenda palatina secundária traumática em cão - relato de caso
RESUMO A fenda palatina é a comunicação entre a cavidade oral e a nasal através de um orifício no palato. Tem diversas etiologias, podendo ser congênita, traumática, por deficiência mineral ou por fatores hormonais. O diagnóstico é realizado por meio de exame físico da cavidade oral, e a correção cirúrgica é o tratamento de escolha. Em animais

4. Bovine Pericardial Patch Augmentation of One Insufficient Aortic Valve Cusp with Twenty-three-year Positive Clinical Follow-up Independent of the Patch Degeneration
Abstract Scientific progress shall ultimately boost the current acceptance level for conservative aortic valve surgery. The present text aimed to report the 23-year long-term follow-up of one patient operated with bovine pericardium cusp extension. Growing confidence in the efficacy of the operation will allow a more expeditious indication for surgical treat

5. Experimental Model of Saccular Abdominal Aortic Aneurysm in Swines with Pericardium Sac
Abstract Objective: To consider modifications in an experimental model of saccular aortic aneurysm, aiming at better reproducibility, to be used in the development of vascular prostheses. Methods: Experimental study in two phases, developed in the Center of Experimental Surgery and Bioterium (CCEB) of the University of Health Sciences of Alagoas (UNCISAL),

6. Use of Bovine Pericardium and Sutureless Biological Glue in Left Ventricular Rupture After Mitral Valve Replacement, Five Years of Follow-up
ABSTRACT 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 h

7. Experimental Study and Early Clinical Application Of a Sutureless Aortic Bioprosthesis
ABSTRACT INTRODUCTION: The conventional aortic valve replacement is the treatment of choice for symptomatic severe aortic stenosis. Transcatheter technique is a viable alternative with promising results for inoperable patients. Sutureless bioprostheses have shown benefits in high-risk patients, such as reduction of aortic clamping and cardiopulmonary bypas

8. Estudo comparativo da biocompatibilidade in vivo de matrizes acelulares de pericárdio bovino e porcino / In vivo biocompatibility study of acellular bovine and porcine pericardium matrices
Acellular matrices are used in tissue engineering for reconstruction or replacement of damaged tissues .In this study acellular matrices were developed using porcine pericardium and bovine pericardium, which contain a large quantity of type I collagen, using an alkaline hydrolysis treatment at the times of 12 hours and 24 hours. The matrices were developed t

9. Arc-to-arc mini-sling 1999: a critical analysis of concept and technology
PURPOSE: The aim of this study was to critically review the Arc-to-Arc mini-sling (Palma's technique) a less invasive mid-urethral sling using bovine pericardium as the sling material. MATERIALS AND METHODS: The Arc-to-Arc mini-sling, using bovine pericardium, was the first published report of a mini-sling, in 1999. The technique was identical to the "tensio

10. Preparação, avaliação físico-química e biológica in vitro de pericárdio bovino conjugado com fibroína de seda/quitosana via liofilização e irradiação / Preparation, physico-chemical and biological in vitro evaluation of bovine pericardium combined with silk fibroin/chitosan via freeze-drying and irradiation
Neste trabalho, a irradiação por feixe de elétrons foi estudada como uma ferramenta para a reticulação do tecido de pericárdio bovino (PB). A conjugação de quitosana e fibroína de seda no tecido de PB liofilizado também foi objeto de estudo deste trabalho. Para isto, amostras de PB foram liofilizadas e irradiadas em um acelerador de elétrons utili

11. The influence of freezing rates on bovine pericardium tissue Freeze-drying
O pericárdio bovino é um material utilizado na fabricação de biopróteses. A liofilização é um método de secagem que vem sendo estudado para a conservação de válvulas cardíacas. A preservação das características do biomaterial é de fundamental importância no bom funcionamento das válvulas. Este artigo é a primeira etapa do desenvolvimento

12. Mechanical, thermal and morphological properties of glutaraldehyde crosslinked bovine pericardium followed by glutamic acid treatment
Major problems with valve bioprostheses are associated with progressive structural deterioration and calcification, directly associated with the use of glutaraldehyde (GA). This work describes the effects of GA processing and borate/glutamic acid buffer treatment on the mechanical, thermal and morphological properties of 0.5% GA crosslinked bovine pericardiu
