Atrial fibrillation (AF) accounts for most embolic strokes, especially in elderly individuals. Although anticoagulation is known to reduce the risk of embolic stroke, a significant proportion of patients have relative or absolute contraindications to anticoagulation. The left atrial appendage has been implicated as the major source of emboli in more than 90% of ischemic strokes in nonvalvular AF. Left atrial appendage occlusion offers an alternative for stroke prevention in patients with an elevated stroke risk (CHADS2 score ≥2 or CHA2DS2-VASc score ≥3) who have a rationale for avoiding long-term oral anticoagulation after a shared decision-making process. However, there remain significant challenges in left atrial appendage occlusion therapy related to patient selection, the procedure itself, and postprocedural patient management decisions. In this review article, we discuss some of these challenges in a case discussion-based approach.

Attention Score in Context
Attention Score in Context
This research output has an Altmetric Attention Score of 5. 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 22 November 2018.
All research outputs
#7,000,448
of 25,382,440 outputs
Outputs from Mayo Clinic Proceedings
#2,238
of 5,151 outputs
Outputs of similar age
#113,001
of 339,234 outputs
Outputs of similar age from Mayo Clinic Proceedings
#33
of 63 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 72nd percentile.
So far Altmetric has tracked 5,151 research outputs from this source. They typically receive a lot more attention than average, with a mean Attention Score of 29.6. This one has gotten more attention than average, scoring higher than 56% 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 339,234 tracked outputs that were published within six weeks on either side of this one in any source. This one has gotten more attention than average, scoring higher than 66% of its contemporaries.
We're also able to compare this research output to 63 others from the same source and published within six weeks on either side of this one. This one is in the 47th percentile – i.e., 47% of its contemporaries scored the same or lower than it.
