Background The aim of this study was to investigate the prevalence and clinical significance of echocardiographic “accretions” on intracardiac leads in patients with permanent pacemakers. Methods Two hundred eleven patients…
Background Apical outpouching, including wall motion abnormalities and aneurysms, has been described in apical hypertrophic cardiomyopathy (ApHCM). Methods Between 1976 and 2006, 193 patients with ApHCM (120 men; overall mean…
Objective An increase in the diastolic to systolic flow velocity ratio (D/S) in the proximal left internal thoracic artery (ITA) after coronary artery bypass grafting (CABG) enables noninvasive assessment of…
In this issue of the Journal of the American Society of Echocardiography , Mottram et al. illustrate the role of echocardiography in the early detection of the expression of a mutation…
Background The purpose of this study was to evaluate the potential of combined use of transthoracic Doppler echocardiographic coronary flow velocity reserve (CFVR) measurements and findings of retrograde coronary flow…
Ischemic mitral regurgitation is a common complication of the healing phase of myocardial infarction. A number of mechanisms have been invoked in its pathogenesis, including alterations of papillary muscle position,…
Background Speckle-tracking imaging is a novel method for assessing left ventricular (LV) function and ischemic changes. The aim of this study was to assess the predictive value of two-dimensional longitudinal…
Background Carotid ultrasound screening (CUS) has been recommended for cardiovascular disease risk prediction, but its effectiveness in clinical practice is unknown. The purpose of this study was to prospectively determine…
Objective The study objective was to evaluate whether a novel global position system (GPS)-like position-sensing technology will enable accurate co-registration of images between imaging modalities. Co-registration of images obtained by…
Background The aim of this study was to investigate the role of carotid plaque in predicting ischemic cardiovascular risk, which has been intensively reported in Western populations but not yet…
