Background Right ventricular (RV) mechanical dyssynchrony may be associated with RV dysfunction. The aim of this study was to investigate the feasibility of measuring RV synchrony in normal children using…
Background The aim of this study was to define the range of left ventricular (LV) velocities and deformation indexes in highly trained athletes, analyzing potential differences induced by different long-term…
Background Right ventricular end-diastolic volume (RVEDV) greater than 150 mL/m 2 is a risk factor for sudden death in patients with tetralogy of Fallot (TOF) after repair. Because of its…
Background Diabetic cardiomyopathy has been characterized by an early impairment of left ventricular (LV) longitudinal function as opposed to preserved LV radial function. Methods Conventional echocardiography and longitudinal (ϵ L…
Background Similar to power-to-weight ratio and weight-to-power ratio, which are measurements of the actual performance of any engine, the ratios of peak power output to left ventricular (LV) mass (peak…
Background Changes in left atrial (LA) volumes after ST elevation myocardial infarction are reported but have not been well described following non–ST elevation myocardial infarction (NSTEMI). Methods Seventy-five patients with…
Background The aims of this study were to determine the usefulness of hand-carried ultrasound devices in pediatric cardiology and to compare the performance of three different hand-carried ultrasound devices in…
Background Wall motion (WM), Doppler-derived measurement of the coronary flow reserve (CFR) in the left anterior descending coronary artery (LAD), and myocardial perfusion imaging (MPI) can be sequentially assessed during…
In this issue of JASE , Dalla Pozza et al. report a device comparison study using three “hand-carried” ultrasound devices chosen for their capability of imaging in the limited space of…
The use of ultrasound has developed over the last 50 years into an indispensable first-line test for the cardiac evaluation of symptomatic patients. The technologic miniaturization and improvement in transducer…
