Metric Options: CountsSelecting the 1-year or 3-year option will change the metrics count to percentiles, illustrating how an article or review compares to other articles or reviews within the selected time period in the same journal. Selecting the 1-year option compares the metrics against other articles/reviews that were also published in the same calendar year. Selecting the 3-year option compares the metrics against other articles/reviews that were also published in the same calendar year plus the two years prior.
Example: if you select the 1-year option for an article published in 2019 and a metric category shows 90%, that means that the article or review is performing better than 90% of the other articles/reviews published in that journal in 2019. If you select the 3-year option for the same article published in 2019 and the metric category shows 90%, that means that the article or review is performing better than 90% of the other articles/reviews published in that journal in 2019, 2018 and 2017.

Article Description
In approximately one third of patients presenting with suspected severe aortic stenosis, there is a discrepancy between a severely reduced aortic valve opening area (< 1 cm) and a non-severe increase of the mean transvalvular gradient (< 40 mmHg). In a substantial number of these cases there is evidence of a severe paradoxical low-flow low-gradient aortic stenosis, characterized by a reduced stroke volume index in the setting of a normal left ventricular ejection fraction. This finding should trigger an extensive diagnostic work-up, including echocardiography, stress echocardiography and computed tomography to rule out measurement errors and to identify the cause(s) of the hemodynamic discrepancy. If the diagnosis of a severe paradoxical low-flow low-gradient aortic stenosis is confirmed and, furthermore, the patient is normotensive and reports stenosis-associated symptoms, the feasibility of an aortic valve replacement should be considered.
