Transcatheter aortic valve implantation has also evolved as a suitable treatment option for degenerative surgical heart valve disease, with considerable experience in the aortic and mitral positions. Success of a valve-in-valve (VIV) procedure depends on four main concepts. These include the following:

This is a retrospective review of 260 patients undergoing TAVI, looking at the relationship between aortic valve calcium score and post procedural paravalvular leakage. The results suggest that the amount of calcification significantly impacts the occurrence, the degree and localization of paravalvular leakage after TAVI.

This manuscript reports on the findings of a meta-analysis of retrospective observational studies comparing clinical outcomes at 1-year in patients treated by either transfemoral (TF) or transapical (TA) transcatheter aortic valve implantation for sever aortic stenosis.

In this retrospective, multicentre study, the authors evaluate clinical outcomes in 139 patients with bicuspid aortic valves undergoing transcatheter aortic valve implantation (TAVI) with either a self or a balloon-expandable prosthesis.

This study examined the effect of the introduction of TAVR on overall AVR rates in the US using the STS and STS/ACC registries. From 2008 to 2013, AVR rates increased at hospitals performing TAVR by 69%, including a 22% increase in surgical AVR; the latter increase was primarily in low- and moderate-risk patients. In contrast, non-TAVR hospital AVR

This is a matched case controlled study of 27 consecutive patients with severe symptomatic aortic stenosis undergoing transcatheter aortic valve implantation (TAVI) with the SAPIEN 3 (SV3)device in 2 centers.

The German Aortic Valve Registry comprises data of 78 centers on conventional, transvascular and transapical valve replacements. After stratification for EuroScore and the German AV score, mortality was comparable with either therapy even for high-risk groups.

WASHINGTON D.C. -- September 16, 2014 -- Use of a dual-filter cerebral protection system reduces the number and volume of cerebral lesions in patients with severe aortic stenosis undergoing transaortic valve replacement (TAVR), according to prospective research presented at the 2014 Transcatheter Cardiovascular Therapeutics meeting (TCT).
