Percutaneous 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 کاملOff-pump tricuspid valved stent implantation: the next step.
OBJECTIVES Off-pump transcatheter valved stent implantation could be a treatment option for patients suffering from symptomatic tricuspid regurgitation (TR) who are classified as inoperable. In this study, we present our recent short-term results of transventricular tricuspid valved stent implantation and compare different stent types for atrial anchorage. METHODS Fifteen pigs received a self...
متن کاملTricuspid valved stent implantation: novel stent with a self-expandable super-absorbent polymer.
OBJECTIVE Trans-catheter aortic and pulmonary valve replacement procedures can result in favorable outcomes in selected patients. The aim of this study was to investigate the functioning of a novel self-expanding valved stent with super-absorbent polymer (SAP) for minimally invasive replacement of the tricuspid valve. METHODS A newly designed nitinol stent with SAP was specially designed for ...
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.
