Clinical TrialUsefulness of Speckle-Tracking Imaging for Right Ventricular Assessment after Acute Myocardial Infarction: A Magnetic Resonance Imaging/Echocardiographic Comparison within the Relation between Aldosterone and Cardiac Remodeling after Myocardial Infarction Study.
Right ventricular (RV) dysfunction after acute myocardial infarction (AMI) is frequent and associated with poor prognosis. The complex anatomy of the right ventricle makes its echocardiographic assessment challenging. Quantification of RV deformation by speckle-tracking echocardiography is a widely available and reproducible technique that readily provides an integrated analysis of all segments of the right ventricle. The aim of this study was to investigate the accuracy of conventional echocardiographic parameters and speckle-tracking echocardiographic strain parameters in assessing RV function after AMI, in comparison with cardiac magnetic resonance imaging (CMR). ⋯ After AMI, RV GLPSS is the best correlate of CMR RV ejection fraction. In patients with inferior AMIs, RV GLPSS displays even higher diagnostic value than conventional echocardiographic parameters.

Comparative StudyThe Miniaturized Multiplane Micro-Transesophageal Echocardiographic Probe: A Comparative Evaluation of Its Accuracy and Image Quality.
The initial experience with the miniaturized multiplane micro-transesophageal echocardiographic probe (MTEE) reported high-quality diagnostic imaging in small infants. The aim of this study was to compare the diagnostic accuracy and image quality of the intraoperative MTEE with the pediatric multiplane transesophageal echocardiographic probe (PTEE). ⋯ Although the image quality of the MTEE is inferior compared with the PTEE, its diagnostic accuracy in infants weighing <5 kg is comparable.
