| Abstract |
Background: The rate of mitral bioprosthesis implantation in clinical practice is increasing. Transcatheter valve-in- valve implantation has been described for high risk patients requiring redo valve surgery. To report our experience with transapical valve-in-valve implantation for failed mitral bioprosthesis. Since 2010, 10 patients have undergone transapical valve-in-valve implantation for failed bioprosthesis in our center. Aortic valve-in-valve implantation was performed in one of them and mitral valve-in-valve implantation in nine. Mean age was 82 ± 4 years and 6 were female (67%). Mean time from original mitral valve (MV) replacement to valve-in-valve procedure was 10.5 ± 3.7 years. Follow-up was completed by all patients with a mean duration of 13 ± 12 months. Preoperatively, all patients presented with significant mitral regurgitation, two with mitral stenosis due to structural valve failure. All nine patients underwent successful transapical valve-in-valve implantation with an Edwards Sapien balloon expandable valve. There was no in-hospital mortality. Mean and median hospital duration was 15 ± 18 and 7 days respectively. Valve implantation was successful in all patients and there were no major complications, except for major femoral access bleeding in one patient. At last follow-up, all patients were alive and in NYHA functional class I or II. Echocardiography follow-up demonstrated that mitral regurgitation was absent or trivial in seven patients and mild in two. At follow-up, peak and mean gradients changed from 26 ± 4 and 8 ± 2 at baseline to 16.7 ± 3 and 7.3 ± 1.5, respectively. Transcatheter transapical mitral valve-in-valve implantation for failed bioprosthesis is feasible in selected high risk patients. Our early experience with this strategy is encouraging. Larger randomized trials with long-term clinical and echocardiographic follow-up are recommended. |

Attention Score in Context
This research output has an Altmetric Attention Score of 6. This is our high-level measure of the quality and quantity of online attention that it has received. This Attention Score, as well as the ranking and number of research outputs shown below, was calculated when the research output was last mentioned on 15 August 2018.
All research outputs
#6,497,306
of 25,382,440 outputs
Outputs from Israel Medical Association Journal
#130
of 846 outputs
Outputs of similar age
#93,973
of 399,683 outputs
Outputs of similar age from Israel Medical Association Journal
#3
of 27 outputs
Altmetric has tracked 25,382,440 research outputs across all sources so far. This one has received more attention than most of these and is in the 74th percentile.
So far Altmetric has tracked 846 research outputs from this source. They receive a mean Attention Score of 4.9. This one has done well, scoring higher than 84% of its peers.
Older research outputs will score higher simply because they've had more time to accumulate mentions. To account for age we can compare this Altmetric Attention Score to the 399,683 tracked outputs that were published within six weeks on either side of this one in any source. This one has done well, scoring higher than 76% of its contemporaries.
We're also able to compare this research output to 27 others from the same source and published within six weeks on either side of this one. This one has done well, scoring higher than 88% of its contemporaries.
