The Mosaic porcine bioprosthesis: Role of age on clinical performance in aortic position

Medtronic Mosaic porcine bioprosthesis - The Annals …

Recognizing the need to incorporate technologies that can potentially address these challenges, the Mosaic valve differs from previously-released tissue valves, in that it incorporates two proprietary technologies - the Medtronic AOA® 1,2 (alpha amino oleic acid) treatment and the Medtronic Physiologic Fixation™ process – which have not been available together in previous stented tissue valves. Both of these technologies have been shown in animal studies to maintain the natural leaflet structure of the valve and to reduce the potential for calcification of the animal tissue.

Medtronic Mosaic Heart Valve Replacement - 12 Year …

Medtronic tissue heart valves for both the aortic and mitral positions have undergone 30 years of development, and three distinct generations of bioprostheses have emerged. The third generation Mosaic bioprosthesis is the result of Medtronic’s commitment to advancing tissue technologies.

Medtronic mosaic porcine heart valve

The Medtronic Mosaic bioprosthesis is a third-generation valve made of porcine (pig) tissue. The tissue is attached to a cloth-covered, flexible plastic frame, called a stent. The bioprosthesis is then sewn into place where the patient’s diseased valve used to be.

The Medtronic Mosaic was implanted in 163 patients (35.6%) and the Carpentier-Edwards Magna in 295 patients (64.4%). Basic demographic data and risk scores were comparable (Table ). The mean implanted valve size was 22.4 ± 1.5 mm for the Medtronic Mosaic, which was significantly larger than the Carpentier-Edwards Magna size (21.8 ± 1.8 mm; P = 0.001). Procedural characteristics including cross-clamp time and intraoperative risk factors were comparable (Table ).

The Medtronic Mosaic® bioprosthetic heart valve (bioprosthesis), carefully crafted from porcine tissue and preserved with innovative techniques, is an artificial heart valve.

Another aspect has to be addressed in the discussion regarding postoperative transvalvular gradients. Previous publications highlighted the variable labelling of valve sizes and also reported a difference in the inner diameter of size-matched prostheses up to 2 mm [, ]. Therefore, studies comparing different aortic valve prostheses according to the labelled implanted valve size have to be interpreted with caution. Our department introduced the Medtronic Mosaic early and previously published a randomized analysis comparing implanted valve sizes in relation to the real annular diameter measured with a hegar dilator []. The implanted Carpentier-Edwards Magna labelled sizes were smaller compared with the Medtronic Mosaic valve for a standardized annular measurement. This was observed again in the current analysis. Not one 19 mm Medtronic Mosaic valve was implanted in this patient population and the average diameter according to the labelled size was 0.6 mm higher in the Medtronic Mosaic group.
