Evaluation of left atrial myocardial deformation in patients with acute MR after STEMI using CMR feature tracking
نویسندگان
چکیده
Background Left atrium (LA) is an important predictor of cardiovascular morbidity and mortality. Data related to LA functional changes during acute MR after ST-segment elevation myocardial infarction (STEMI) are limited. CMR is rapidly evolving imaging modality and feature tracking becomes very promising technique for assessment of myocardial deformation. The aim of this study was to investigate LA functional changes during acute MR in patients with STEMI using cardiac magnetic resonance (CMR) feature tracking.

Predictors and prognostic value of left atrial remodelling after acute myocardial infarction
PURPOSE Left atrial (LA) volume is a strong prognostic predictor in patients following ST-segment elevation myocardial infarction (STEMI). However, the change in LA volume over time (LA remodelling) following STEMI has been scarcely studied. We sought to identify predictors for LA remodelling and to evaluate the prognostic importance of LA remodelling. METHODS This is a subgroup analysis from...
متن کاملQuantification of left atrial strain and strain rate using cardiovascular magnetic resonance myocardial feature tracking
Background Cardiovascular Magnetic Resonance myocardial feature tracking (CMR-FT) is a quantitative technique tracking tissue voxel motion on standard steady-state free precession (SSFP) cine images to assess ventricular myocardial deformation. The importance of left atrial (LA) deformation assessment is increasingly recognized and can be assessed with echocardiographic speckle tracking. Howeve...
متن کاملSerial assessment of left atrial deformation in patients undergoing pulmonary vein isolation: a cardiovascular magnetic resonance feasibility study
Background Left atrial (LA) performance quantification using Cardiovascular Magnetic Resonance (CMR) is of growing interest. There is evidence that declined left atrial function is associated with a poorer outcome following pulmonary vein isolation (PVI) in atrial fibrillation (AF). Furthermore, the influence of PVI on left atrial performance has not yet been investigated comprehensively. This ...
متن کاملEvaluation of ejection fraction in patients with acute myocardial infarction undergoing percutaneous coronary intervention
Introduction: Percutaneous coronary intervention (PCI) is a reperfusion strategy to increase life expectancy and ejection fraction (EF) in ST-segment elevation myocardial infarction (STEMI) patients. We investigated the effect of location, severity, type of lesion, number and type of vessel involved and time of angioplasty on the increase in EF in STEMI patients undergoing primary PCI (P-PCI) a...
