| Abstract |
The indication for surgery in asymptomatic severe mitral regurgitation (SMR) with preserved left ventricular ejection fraction (LVEF) is controversial. We sought to study 3D myocardial mechanics in this population and test 3D-speckle tracking (3DST) parameters as possible predictors of events. 45 asymptomatic patients with SMR and LVEF >60 % and 20 control individuals without cardiac disease underwent 3DST echocardiography. MR group additionally underwent further clinical monitoring. Dyspnea, LVEF under 60 %, or admissions for heart failure were considered as events. When compared with control group, MR group showed lower percentage of global 3D strain, (35.4 ± 9.1 vs. 43.9 ± 10.6; p = 0.003), lower radial strain, lower area change rate and higher end-diastolic volume. In a follow-up time of 23.2 ± 14.5 months we found 15 events (33.3 %). When comparing the remaining patients with this new-onset HF group we found significant differences in longitudinal strain (-17.9 ± 3.3 vs. -15.8 ± 2.1; p = 0.036), area strain (AS) (-48.6 ± 4.6 vs. -43.7 ± 6.2; p = 0.006), circumferential strain (-35.8 ± 4.7 vs. -31.8 ± 6.1; p = 0.034), 3D LVEF (67.1 ± 4.6 vs. 63.0 ± 7.4; p = 0.034) and E/E' index (13.5 ± 3.9 vs. 19.3 ± 9.5; p = 0.006). In multivariate Cox regression AS alone was the only independent predictor. A cutoff value of AS greater than -41.6 % reached a hazard ratio of 4.41 (p = 0.004) for prediction of events. In asymptomatic patients with SMR and preserved ejection fraction, 3DST derived AS is a promising tool for predicting the development of heart failure. This finding may be useful for guiding the selection of patients for early mitral valve repair/replacement surgery even if they are asymptomatic. |

Attention Score in Context
This research output has an Altmetric Attention Score of 3. 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 07 August 2016.
All research outputs
#15,092,197
of 25,374,917 outputs
Outputs from The International Journal of Cardiovascular Imaging
#606
of 2,012 outputs
Outputs of similar age
#159,094
of 315,801 outputs
Outputs of similar age from The International Journal of Cardiovascular Imaging
#10
of 43 outputs
Altmetric has tracked 25,374,917 research outputs across all sources so far. This one is in the 40th percentile – i.e., 40% of other outputs scored the same or lower than it.
So far Altmetric has tracked 2,012 research outputs from this source. They receive a mean Attention Score of 2.3. This one has gotten more attention than average, scoring higher than 69% 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 315,801 tracked outputs that were published within six weeks on either side of this one in any source. This one is in the 49th percentile – i.e., 49% of its contemporaries scored the same or lower than it.
We're also able to compare this research output to 43 others from the same source and published within six weeks on either side of this one. This one has done well, scoring higher than 76% of its contemporaries.
