Article Synopsis
- The study explored the effectiveness of quantitative assessments of the left atrial appendage (LAA) for identifying thrombus compared to traditional qualitative assessments.
- Researchers analyzed data from 138 patients undergoing transesophageal echocardiography and calculated a cavity-to-wall (C/W) pixel density ratio of the LAA.
- The C/W ratio showed a strong correlation with both qualitative assessments and thromboembolic events, suggesting it could serve as a reliable and easily quantifiable method to assess thromboembolic risk in patients with atrial fibrillation.
Objectives: The purpose of this study was to determine the prognostic value of feature-tracking global longitudinal strain (GLS) measured during vasodilator stress cardiac magnetic resonance (CMR) imaging.
Background: Prior studies have suggested that blunted myocardial strain during dobutamine stress echocardiography may be associated with adverse prognosis. Recent developments in CMR feature-tracking techniques now allow assessment of strain in clinical practice using standard cine images without specialized pulse sequences or complex post-processing.
Objectives: The aim of this study was to evaluate the incremental prognostic value of global coronary flow reserve (CFR) in patients with known or suspected coronary artery disease who were undergoing stress cardiac magnetic resonance (CMR) imaging.
Background: Coronary microvascular dysfunction results in impaired global CFR and is implicated in the development of both atherosclerosis and heart failure. Although noninvasive assessment of CFR with positron emission tomography provides independent prognostic information, the incremental prognostic value of CMR-derived CFR remains unclear.
Objectives: This study sought to evaluate the prognostic value of cardiac magnetic resonance (CMR)-derived mitral annular plane systolic excursion (MAPSE) in a large multicenter population of patients with hypertension.
Background: In patients with hypertension, cardiac abnormalities are powerful predictors of adverse outcomes. Long-axis mitral annular movement plays a fundamental role in cardiac mechanics and is an early marker for a number of pathological processes.
