This manuscript offers a comprehensive and easy to read review of annular rupture during TAVI. The authors explain the pathophysiology of this complication and classify it according to the anatomical location. They also discuss the management options in terms of diagnosis and treatment.

This a retrospective study of 175 patients who had survived more than 12 months following TAVI and for whom there were clinical and echocardiographic follow up data. Outcomes were compared between patients with significant (grade II or more) aortic regurgitation (AR) and those without significant aortic regurgitation (less than grade II).

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 is a retrospective study comparing outcomes in 25 octogenarian patients undergoing percutaneous mitral valve intervention with the Mitraclip device and 35 octogenarian patients undergoing surgical mitral valve repair or replacement for isolated mitral regurgitation.

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
