In this study, we used the surface plasmon resonance (SPR) to estimate filling defects, including incomplete mold filling and trapped air bubble.
The authors suggested a need to refine the broad clinical use of the mitral E/E′ ratio to estimate filling pressures and cautioned against the direct inference of relationships in patients with a decompensated state with significant LV systolic dysfunction, cardiac remodeling, or biventricular pacing.
Diagram in top panel illustrates the two types of estimates plotted: individual estimates (filled dots, means of species pairs connected by solid lines) and lineage estimates (open dots, species pairs connected by dash lines).
In fact, due to the abundance of data, it is always possible except in the case of long gaps to find close to optimal subsets from which g, h estimates fill the gaps of the graphs of Fig. 3, and are on the general trend.
Also, it has been suggested that serial intrapatient measurements of natriuretic peptide might more adequately correlate with filling pressures, rather than single measurements [ 10], and so serial measurement of NT-proBNP or BNP might still be useful in estimating filling pressures.
For the analysis, missing values were estimated and filled in by a method based on Bayesian inference [ 36] (see the additional files 1 and 2).
With regard to PM10, the estimate accounting for funnel plot asymmetry was 1.00 (95% CI: 0.92, 1.08); this estimate required filling in the funnel plot with four hypothetical studies.
A blinded board-certified cardiologist reviewed LBEs to estimate LA filling pressures following ASE guidelines.
The diagnosis and management of CHF remain a clinical challenge; decisions are based on clinical assessments of volume status, which are used to estimate cardiac filling pressures [3].
Therefore, we also conducted the Trim-and-Fill method, which trims unmatched values around the initial estimate and fills the funnel plot with imputed missing studies in an iterative process to achieve symmetric funnel plots (Duval and Tweedie 2000).
