Detailed explanation-1: -Tissue valves, which are made from pig heart valves or cow heart-sac tissue, typically last about 15 years.
Detailed explanation-2: -The Mosaic™ heart valve is one option for patients with aortic or mitral valve disease. The Mosaic heart valve is made from the heart valve of a pig (porcine). A pig’s heart valve anatomy is similar to that of a human heart. In order to implant the valve in the heart, the tissue is mounted on a flexible frame.
Detailed explanation-3: -These MICS procedures are usually performed through the third or fourth intercostal space using a limited 5-to 8-cm incision along the inframammary crease. The patient is commonly positioned supine with a slight bump under the right hemi-thorax to allow complete access to the sternum and both groins.
Detailed explanation-4: -Porcine aortic valve (PAV) xenografts are the most frequently used type of bioprosthetic (BP) valve for the replacement of damaged or diseased heart valves.
