This manuscript reports on data from the UK registry from 2007 to 2012 including 3980 TAVI procedures and a 6 year follow up. The authors carry out a good analysis of trends, risk factors for mortality and results. They found little change in the characteristics of patients treated in the UK by TAVI from 2007 to 2012.

The authors analyzed all patients greater than age 18 in the National Inpatient Sample from 1998-2011 to evaluate trends and outcomes of tissue vs. mechanical aortic valve replacements. Implantation of tissue valves increased overall from 38% to 64% when comparing the earlier era to the later one.

This manuscript describes the findings of a retrospective analysis of 874 consecutive high risk or inoperable patients undergoing TAVR in three different centres, evaluating outcomes after up to three years of follow up. In-hospital mortality was 5%. Early mortality was strongly associated with the occurrence of procedural complications.

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:

Results from the European REdo Cardiac Operation Research Database (RECORD) indicate that outcome of redo aortic valve replacement is influenced by baseline risk factors and perioperative complications. Hospital mortality was seen in 5.1% of 711 evaluated cases.
January 10, 2015
Outcomes of surgical AVR were summarized from the STS Cardiac Surgery Database 2002-2010 to establish contemporary data for different surgical risk groups (low <4% risk, intermediate 4%-8% risk, high >8% risk). 80% were low risk, 6% were high risk. Hospital mortality was lower than predicted by STS PROM for all groups (low: 1.4$ vs 1.7%; inte

This study randomized 100 patients with AS to full sternotomy AVR with a conventional prothesis or hemisternotomy with a rapid deployment prosthesis. CPB times were similar, but Ao crossclamp times were 24% shorter in the rapid deployment group. Acute outcomes were similar. The rapid deployment group had a lower transvalvular gradient and a lower

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.
