Cardiac Imaging to Assess Left Ventricular Systolic Function in Atrial Fibrillation

The validity and reproducibility of systolic function assessment in patients with atrial fibrillation (AF) using cardiac magnetic resonance, echocardiography, nuclear imaging computed tomography is unknown. A prospectively-registered systematic review was performed, including 24 published studies AF at the time reporting or data on left ventricular parameters (PROSPERO: CRD42018091674). Data extraction risk bias were performed by 2 investigators independently synthesized qualitatively. In 3 resonance (40 patients), ejection fraction stroke volume measurements correlated highly catheter angiography (r ?0.85), intra- and/or interobserver variability low. From (171 there no external validation assessments but intra intersession 18 echocardiography (2,566 showed high global longitudinal strain tissue Doppler s' angiography-derived dP/dt ?0.88). Global myocardial performance index both associated adverse cardiovascular events. Reproducibility better when selecting an index-beat (where preceding R-to-R intervals are similar) compared to averaging consecutive beats. There relating tomography. Most small biased selection good quality images, limiting clinical extrapolation results. remains unclear due paucity good-quality data.
