Biopolymer/Suture Polymer Interaction: Is It a Key of Bioprosthetic Calcification?

The aim of this study was to evaluate the effect of suture material made of polyester (PET), polypropylene (PP), and polytetrafluoroethylene (PTFE) on the calcification of a bovine pericardium (BP) consisting of collagen biopolymer preserved with an epoxy compound. Non-porous film made of the synthetic reinforced polymer REPEREN^(®) was chosen as a control material. Samples of the material (sutured or non-sutured with each of the three types of surgical sutures) were implanted subcutaneously in...

Infectious pseudoaneurysm of the apex of the left cardiac ventricle in a drug addict patient: report of a case

A 43-year-old patient presented to the emergency room due to chest pain, loss of consciousness and an episode of pyrexia. The assessment quickly revealed an infectious pseudoaneurysm of 4.5 cm of the left ventricle apex. The patient underwent emergency cardiac surgery with a large resection of the apical left ventricular cardiac tissues. The surgical reconstruction was performed using a bovine pericardial patch. Associate treatment was targeted intra-veinous (IV) antibiotics, post-operative...

Transabdominal and transvaginal repair of vesico-vaginal fistula with bovine pericardium (Tutopatch). A double case report

Vesico-vaginal fistula (VVF) is an abnormal connection between the bladder and vagina, usually occurring after complex oncologic gynecologic surgeries. It typically presents as continuous urinary incontinence and is diagnosed through clinical examination, imaging, and cystoscopy. Conservative management rarely achieves healing, making surgical repair the preferred option. We report two cases of VVF treated with Tutopatch®, a bovine pericardium-derived graft, used as an interposition graft via...
