| Abstract |
The diagnostic role of echocardiographic and hemodynamic assessment in acute mitral regurgitation (AMR) remains unclear. The central question of this study was to determine if echocardiographic and hemodynamic parameters can predict early clinical events in AMR. AMR was induced by percutaneously severing the mitral valve chordae tendineae in 39 Yorkshire pigs. Immediately after AMR induction, echocardiographic and hemodynamic exams were performed, and compared between those who died and those who survived within 30-days of the procedure. Echocardiographic indices of MR severity as well as the left atrial pressure showed significant differences between survivors and non-survivors in univariate analysis. Multi-variate logistic regression analysis revealed that echocardiography-derived regurgitant fraction and vena contracta as well as mean left atrial pressure could be used to segment the cohort into survivors and non-survivors. Our study demonstrated, for the first time, that echocardiographic and hemodynamic assessment of AMR provides predictive information on early clinical events in a clinically relevant animal model of AMR. |

Attention Score in Context
This research output has an Altmetric Attention Score of 2. 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 26 July 2017.
All research outputs
#15,745,807
of 25,382,440 outputs
Outputs from The International Journal of Cardiovascular Imaging
#684
of 2,012 outputs
Outputs of similar age
#179,611
of 326,269 outputs
Outputs of similar age from The International Journal of Cardiovascular Imaging
#17
of 48 outputs
Altmetric has tracked 25,382,440 research outputs across all sources so far. This one is in the 37th percentile – i.e., 37% 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 63% 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 326,269 tracked outputs that were published within six weeks on either side of this one in any source. This one is in the 43rd percentile – i.e., 43% of its contemporaries scored the same or lower than it.
We're also able to compare this research output to 48 others from the same source and published within six weeks on either side of this one. This one has gotten more attention than average, scoring higher than 60% of its contemporaries.
