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...
متن کاملQuantitative analysis of paravalvular leak of transcatheter aortic valves using cardiac MR
Background There is now extensive registry and clinical trial data demonstrating an increased incidence of paravalvular leak following transcatheter aortic valve implantation (TAVI) when compared with open aortic valve replacement (AVR). Despite recent improvements in both hardware and software, echocardiographic measurement of aortic regurgitation (AR) largely remains qualitative in nature. Ca...
متن کاملRisk 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 ...

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 ...
متن کاملPlugging paravalvular leaks after transcatheter aortic valve replacement: why and how?
SEE PAGE 681 P aravalvular leaks or paravalvular regurgitation (PVR) occur after most transcatheter aortic valve replacements (TAVRs) utilizing the firstand second-generation devices. They are generally mild and are seemingly of no clinical significance, although controversy exists on this point (1,2). When PVR is moderate or greater, it is clinically significant, blunting clinical improvement ...
