The article offers information on replacing an aortic valve without open-heart surgery. Topics discussed include traditional valve replacement surgery, drawbacks of the less-invasive technique known as transcatheter aortic valve replacement (TAVR), and questions to ask if the heart surgeon recommends an...

Method of replacing atrioventricular heart valves using flexible tubes A method is disclosed for using tubular material to replace a semilunar heart valve (i.e., an aortic or pulmonary valve). To create such a replacement valve, the native valve cusps are removed from inside an aorta or pulmona...
Embodiments of a prosthetic heart valve comprise an annular main body, an atrial cap extending radially outwardly from the atrial end of the main body, and a plurality of ventricula
The faulty natural aortic valve, next to the left ventricle (2), is excised and removed. A fastener driving tool with a cuff (19) attached is inserted through the incision (200). The knob (36) is rotated while holding handle (35) to deploy the fasteners through the cuff (19) to ...
