Steps toward percutaneous aortic valve replacement.
BACKGROUND To date, the surgical approach is the only option to replace the aortic valve. Percutaneous pulmonary valve replacement has recently opened new perspectives on transcatheter replacement of cardiac valves. We report our experience of aortic valve replacement through a percutaneous technique in lambs. METHODS AND RESULTS A bovine jugular vein containing a valve was dissected and sutu...
متن کاملPercutaneous valved stent implantation in the ascending aorta for the treatment of very high-risk aortic regurgitation: an animal study.
PURPOSE We investigated the effects of percutaneous valved stent implantation in the ascending aorta as an alternative treatment for aortic regurgitation in a canine model. MATERIALS AND METHODS A total of 16 healthy dogs weighing an average of 18.3 ± 2.1 kg were used for the establishment of animal models of chronic aortic regurgitation by percutaneous aortic valve perforation and balloon di...
متن کاملPercutaneous valved stent implantation above the coronary ostia.
BACKGROUND In recent years, some experimental and clinical studies on transcatheter aortic valve implantation (TAVI) have been conducted. TAVI is indicated in patients with calcified pure or predominant aortic stenosis. The risk of this technique is still high. Aortic valved stent implantation above the coronary ostia might avoid blocking the coronary ostia. METHODS AND RESULTS Twenty healthy...
متن کاملTransapical mitral valve implantation: the Lutter valve
The development of transcatheter techniques for treatment of severe mitral valve regurgitation in the beating heart is focus of recent research. An off-pump treatment technique poses great benefits, particularly for multimorbid patients, often being non-compliant to the gold standard treatment, being open heart surgery with use of a cardiopulmonary bypass. Thereto, two approaches are being fo...
متن کاملPercutaneous aortic valve replacement: computed tomography scan after valved stent implantation in human cadaver hearts.
Computed tomography scans were performed before and after aortic valve resection with consecutive implantation of a valved stent in human hearts with highly calcified aortic valves in situ (n=2). This demonstrates that the valved stent shows better fitting in the annulus after removal of the native valve.
