Accelerated structural deterioration due to calcific degeneration of bioprosthesis may occur in: children, adolescents, young adults, and patients with altered calcium metabolism (e.g., chronic renal failure, or hyperparathyroidism). Contegra is an integrated valved conduit for reconstruction or replacement of the natural right ventricular outflow tract (RVOT) or replacement of a failed homograft or composite pulmonary conduit. (Care should be taken to avoid water entering the ear. "MR Safe", nonmetallic porcine valve for surgical implantation, "MR Conditional" Transcatheter Aortic Valve Replacement (TAVR), "MR Conditional" Bi-leaflet mechanical valve. No direct clinical evaluation of the benefits of AOA treatment in humans has been conducted. With an updated browser, you will have a better Medtronic website experience. (Case courtesy of Dr Matt A. Morgan, "MR Conditional" Cardioband C-shaped annuloplasty device being anchored in the mitral annulus. Specific instructions on how to maintain proper hygiene of the operative ear should be given to the patient. Roots arepressurized at 40 mm Hg with glutaraldehyde. The Hemashield Woven Double Velour Vascular Graft is not approved for use as a coronary artery replacement. Suitable for Future Interventions Valve dimensions and geometry enable future valve-in-valve (ViV) replacements. Implantation of substantially oversized Mosaic Porcine Aortic Bioprostheses Model 305 can potentially lead to cases of higher-than-expected transvalvular gradients. MR Conditional, nonmetallic frame mitigates risk of corrosion betweensurgical valve and transcatheter valve stent materials. Products This includes: Handle (234 mm length) pliant, without locknut to be used with Mosaic or Mosaic Ultra prostheses, Handle (368 mm length) pliant, without locknut to be used with Mosaic or Mosaic Ultra prostheses, Mosaic Mitral Obturator Set (no handles, no tray). Contraindications: The Medtronic Open Pivot Heart Valve is contraindicated in patients unable to tolerate anticoagulation therapy. High-performance stent that allows for absorption of stress produced during the cardiac cycle. Physiologic Fixation, our advanced tissue fixation process, to mitigate biomechanical failures and promote long-term valve durability by: Improving preservation of valve structure and leaflet function, allowing it to function similar to a native valve. Carpentier-Edwards annuloplasty rings, Models 4400 and 4500, marketed from 1980 to 1983, were made of stainless steel. It is recommended that EpiDisc be used immediately after the opening of the pouch; discard any unused portion of the device. "MR Conditional" mitral annuloplasty device on chest x-ray. Protects tissue from inadvertent damage and prevents entanglement with the sub-valvular apparatus. Chole RA and Brummet RE, et al. The Mosaic bioprosthesis is an evolution in durability and implantability, based on the proven platform of the Hancock II valve. A subset of these valves have required explantation within five years of implantation at an overall occurrence rate of 0.1% (one explant per 1000 aortic implants).
