Oi Ling B. Kwan, RDCS Cardiac sonographers have always played an important role in echocardiography. Whether applying the technology daily as a diagnostic tool, participating in research and development of…
Background It has been reported that localized high velocity may be recorded by continuous-wave Doppler interrogation through the smaller central orifices of bileaflet mechanical heart valves (BMHV) and that this…
Background Patients with ventriculoarterial discordance, such as congenitally corrected and d-transposition of the great arteries, may undergo a morphologic left ventricular (LV) training strategy consisting of surgical pulmonary artery band…
Benjamin F. Byrd III, MD, FASE I am honored to assume the Presidency of the American Society of Echocardiography (ASE). I follow in the footsteps of many distinguished cardiologists and…
Background Sleep disturbance caused by obstructive sleep apnea is recognized as a contributing factor to adverse cardiovascular outcomes. However, the effect of restless legs syndrome, another common cause of fragmented…
Objective To evaluate, by noninvasive coronary flow velocity reserve (CFVR), whether patients with asymmetric hypertrophic cardiomyopathy (HC), with or without left ventricular outflow tract obstruction, demonstrate significant regional differences of…
Background Single ventricle (SV) exercise performance is impaired and limited by reduced ventricular preload reserve. The atrium modulates ventricular filling, and enhancement of atrial compliance can increase cardiac performance. We…
Background Long-term outcome in repaired tetralogy of Fallot (TOF) is related to chronic pulmonary insufficiency (PI), right ventricular (RV) dilation, and deterioration of RV function. The aim of this study…
Background An increased aortic pulse wave velocity (PWV), a marker of arterial stiffness, is associated with poor prognosis in various diseases. In patients with heart failure (HF), an increased aortic…
Background Despite a few experimental studies showing a dose-dependent myocardial depressive effect of propofol anesthesia induction, few clinical data are available to determine its precise impact on myocardial function, probably…
