In this manuscript the authors describe a systematic review of 71 cases of transcatheter heart valve embolization. In 72% of the patients, the prosthesis used was a balloon expandable one. In most cases valve embolization occurred soon after implantation and it happened in the aortic direction.

Aortic valve calcium score is a significant predictor for the occurrence of post-interventional paravalvular leakage after transcatheter aortic valve implantation — Results from a single center analysis of 260 consecutive patients
December 30, 2014
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.
Predictors of 1-year mortality in patients with aortic regurgitation after transcatheter aortic valveimplantation: an analysis from the multicentre German TAVI registry
June 26, 2014
In this study the authors use data from 1432 patients included in the German TAVI registry to identify variables which predict poor outcome in patients left with more than mild aortic regurgitation (AR) following TAVI. The Medtronic Core Valve prosthesis had been used in the great majority of the procedures.
Propensity matched analysis of longterm outcomes following transcatheter based aortic valve implantation versus classic aortic valve replacement in patient with previous cardiac surgery
June 20, 2014
This single-centre propensity matched study aimed to compare the outcomes between patients undergoing transapical TAVI or surgical aortic valve replacement in patients who have previously undergone cardiac surgery. Patients who underwent procedures between 2005 and 2012 were included with 40 patients in each group following propensity matching.
Coronary artery disease severity and aortic stenosis: clinical outcomes according to SYNTAX score in patients undergoing transcatheter aortic valve implantation
April 9, 2014
In this study the authors looked at the impact of coronary artery disease (CAD) in a single series of 445 patients undergoing TAVI for aortic valve stenosis. The pre-established primary endpoint of the study was a composite of cardiovascular death, stroke, or myocardial infarction (MI)—at 1 year.
