Immediate Closure of Paravalvular Leak After Transcatheter Aortic Valve Implantation

Percutaneous closure of paravalvular leak after transcatheter aortic valve replacement.

An 86-year-old male underwent TAVR with a 26 mm Sapien valve, co valve, moderate-to-severe paravalvular AI persisted. The patient quick catheter was advanced across the tract over a stiff angled glidewire; a reduction of AI and rapid clinical recovery. (A) TEE long-axis and (B) shor confirms the 4-F MP catheter has been advanced outside the struts of th resulting in substantial reduction of AI ...

Risk factors for paravalvular leak after transcatheter aortic valve implantation

Many studies have shown that transcatheter aortic valve implantation (TAVI) improves outcomes in patients with severe aortic stenosis in whom a classical surgical procedure cannot be performed due to the high risk. As one of the most frequent periprocedural complications of TAVI, paravalvular leak significantly affects the short- and long-term prognosis for patients undergoing implantation. In ...

Paravalvular aortic leak after transcatheter aortic valve replacement: current knowledge.

397 T ranscatheter aortic valve replacement (TAVR) is now well-established as the standard of care for patients with severe symptomatic aortic stenosis who are deemed inoperable , 1 and is seen as an alternative treatment option to surgical aortic valve replacement (SAVR) in a subset of patients with high postoperative mortality. 2 The native valve is typically not removed but instead crushed b...

In vitro hemodynamic testing of Amplatzer plugs for paravalvular leak occlusion after transcatheter aortic valve implantation.

OBJECTIVE We aimed to in-vitro test Amplatzer devices (Amplatzer Vascular Plug II and Amplatzer Vascular Plug III, SJM, St. Paul, MN) in closing PVL generated by transcatheter balloon expandable aortic valve prosthesis in order to quantify the effective treatment of PVL. BACKGROUND Transcatheter aortic valve implantation (TAVI) procedures represent the treatment of choice for high risk patien...
