"Bioprosthesis valve cardu00ecaca without stent, and processes for total replacement of the root of an aortic valve in a patient cardu00ecaca endogenous mamu00ecfero,And for surgical replacement of a valve cardu00ecaca and a segment of the vascular tissue adjacent a patient mamu00ecfero ".This is an aortic bioprosthesis without stent (devoid of structure inhibiting stenosis and coronary arterial segments without ligaments and clear.Stretching from the same, and processes for surgical replacement of cardiac valves aortic and / or aortic (e.g.Lung) using the aortic bioprosthesis without stent.The presence of coronary segments clear and devoid of ligaments facilitates anastomosis from end to end of the native coronary arteries of the patient and / or bypass graftsCoronary arterial to coronary segments existing bioprosthesis even when the native coronary arteries (coronary grafts) are too short or short to reach paThe network of the aortic segment of the bioprosthesis.The presence of coronary segments clear and devoid of ligaments also eliminated the need to remove a "button" or segments of the native aorta in relation to the segments art.Eriais native coronary prior to the deployment of bioprosthesis, thus being beneficial to patients whose ascending aorta is diseased or otherwise compromised.
