primary malignant neoplasms of the pericardium are rare and are predominantly mesotheliomas, followed by benign localized fibrous mesothelioma, malignant fibrosarcoma, angiosarcoma and benign and malignant teratomas. 1 this article concerns an atypical presentation of this malignant tumor with symptoms and signs of pericardial effusion. this unusual feature was complete encasement of the heart ...

OBJECTIVE To determine the proportion between the segments of the normal human tricuspid valve (TV) annulus and its use as a parameter for ring annuloplasty "in vitro" and "in vivo". METHODS Digital images of the tricuspid ring of 30 human cadaveric hearts, without fixation and without tricuspid regurgitation (TR), were analyzed and the proportion between the antero-posterior and septal segme...

attempted with BioGlue surgical adhesive (Cryolife International Inc, Kenesaw, GA), which is a polymer of bovine serum albumin and glutaraldehyde that reaches bonding strength within 2 minutes of mixing and application. The patient was placed back onto bypass and cooled, and the heart was perfused with cardioplegic solution. BioGlue was then applied to the external surface of the dehisced margi...

HYPOTHESIS Bovine pericardium (BP) demonstrates improved intraoperative hemostasis and equivalent perioperative morbidity compared with Dacron when used as patch material for angioplasty following carotid endarterectomy. OBJECTIVE To prospectively compare BP and Dacron patch angioplasty after carotid endarterectomy in a randomized fashion. METHODS Ninety-five consecutive primary carotid end...

The present study was designed to carry out an in vivo and in vitro comparative evaluation of three bio-scaffold augmentation devices used for superficial digital flexor tenorrhaphy in donkeys. Twenty-four clinically healthy donkeys were assigned for three treatment trials (n = 8) using one of three bioscaffold materials (glycerolized bovine pericardium xenograft, tendon allograft and allograft...

Aim: To present a challenging case of hypotony after trabeculectomy and its treatment. Case description: A 22-year-old woman with juvenile glaucoma underwent a conventional trabeculectomy with mitomycin C on the right eye (OD). In the immediate postoperative period, we observed a hyperfiltration bleb with hypotony refractory to conservative measures leading to hypotony maculopathy. A surgical r...

BACKGROUND AND PURPOSE Carotid endarterectomy (CEA) with patch angioplasty produces greater results than with primary closure; however, there remains uncertainty on the optimal patch material in CEA. A systematic review of randomized controlled trials (RCTs) was performed to evaluate the effect of angioplasty using venous patch versus synthetic patch material, and Dacron patch versus polytetraf...

BACKGROUND The reported incidence of mesh infection in contaminated operative fields is as high as 30% regardless of the material used. Recently, mesenchymal stem cells (MSCs) have been shown to possess favorable immunomodulatory properties and improve tissue incorporation when seeded onto bioprosthetics. The aim of this study was to evaluate whether seeding noncrosslinked bovine pericardium (V...

Bioprosthetic valves fail frequently because of pathological mineralization, a process that begins in cell remnants of the glutaraldehyde (GLUT) fixed tissue. Other pathological cardiovascular calcification and physiological mineralization in skeletal/dental tissues are both largely initiated in cell-derived membranous structures (often called "matrix vesicles"), and the enzyme alkaline phospha...
