BACKGROUND: The American Society of Echocardiography Committee on Pediatric Echocardiography Laboratory Productivity was formed in 2011 to study institutional factors that could influence the clinical productivity of physicians and sonographers in academic pediatric echocardiography laboratories. In the previous two surveys, staff clinical productivity remained stable while total echocardiography volumes increased. This third survey was designed to assess how clinical productivity is associated with laboratory infrastructure elements such as training, administrative tasks, quality improvement, research, and use of focused cardiac ultrasound (FCU)...

BACKGROUND: Normal electrocardiographic (ECG) results have been reported to be associated with a low prevalence of structural heart disease and thus may preclude the need for transthoracic echocardiographic (TTE) imaging. The goal of this study was to determine the prevalence of important TTE abnormalities in patients with a normal ECG referred for TTE imaging. METHODS: Consecutive electrocardiograms over 6 months were reviewed. Patients with a normal ECG who underwent TTE imaging within 30 days formed the study group...

BACKGROUND: Diabetes and obesity are both worldwide growing epidemics, and both are independently associated with increased risk for heart failure and death. The aim of this study was to examine the additive detrimental effect of both diabetes and increasing body mass index (BMI) category on left ventricular (LV) myocardial systolic and diastolic function. METHODS: The present retrospective multicenter study included 653 patients (337 with type 2 diabetes and 316 without diabetes) of increasing BMI category...

BACKGROUND: Current diagnostic criteria for noncompaction cardiomyopathy (NCC) lack specificity, and the disease lacks prognostic indicators. Reverse apical rotation (RAR) with abnormal rotation of the cardiac apex in the same clockwise direction as the base has been described in adults with NCC. The aim of this study was to test the hypothesis that RAR might differentiate between symptomatic NCC and benign hypertrabeculations and might be associated with ventricular dysfunction. METHODS: Echocardiograms from 28 children with NCC without cardiac malformations were prospectively compared with those from 29 age-matched normal control subjects...

BACKGROUND: Ventricular dysfunction is associated with increased morbidity and mortality in children with hypoplastic left heart syndrome. The aim of this study was to assess the diagnostic performance of conventional and speckle-tracking echocardiographic measures of right ventricular (RV) function before bidirectional cavopulmonary anastomosis palliation in predicting death or need for heart transplantation (HTx). METHODS: RV fractional area change (RVFAC) and longitudinal and circumferential strain and strain rate (SR) were measured in 64 prospectively recruited patients with hypoplastic left heart syndrome from echocardiograms obtained before bidirectional cavopulmonary anastomosis surgery...

BACKGROUND: Right ventricular (RV) dysfunction is associated with adverse long-term outcomes in patients with tetralogy of Fallot. Little is known about RV function in the first years after surgical repair. The aim of this study was to investigate perioperative changes in myocardial deformation using global longitudinal strain. METHODS: A retrospective analysis of patients with surgically repaired tetralogy of Fallot was performed. Global longitudinal peak systolic RV strain was measured on early postoperative echocardiograms, two subsequent postoperative echocardiograms through 2 years postoperatively, and preoperative echocardiograms, when available...

BACKGROUND: Transthoracic echocardiography (TTE) and myocardial perfusion imaging (MPI) are used in cardiac patients. In this study the radiation exposure of sonographers performing TTE following MPI was evaluated. METHODS: Of 40 study patients, 30 underwent same-day 99m Tc sestamibi MPI and TTE, while another 10 underwent only TTE. Patients who underwent both studies were divided into three groups: right-handed TTE performed by an echocardiographer and right- and left-handed TTE performed by a cardiac sonographer...

BACKGROUND: Treatment of nonculprit coronary stenosis during primary percutaneous coronary intervention in patients with ST-segment elevation myocardial infarction may be beneficial, but the mode and timing of the intervention are still controversial. The aim of this study was to examine the significance and prognostic value of preserved coronary flow velocity reserve (CFVR) in patients with nonculprit intermediate stenosis early after primary percutaneous coronary intervention. METHODS: Two hundred thirty patients with remaining intermediate (50%-70%) stenosis of non-infarct-related arteries, in whom CFVR was performed within 7 days after primary percutaneous coronary intervention, were prospectively enrolled...

BACKGROUND: Coronary flow velocity reserve (CFVR) and left ventricular contractile reserve (LVCR) have demonstrated prognostic importance in patients with diabetes. The aim of this study was to investigate the prognostic contribution of combined evaluation of CFVR and LVCR in patients with diabetes with nonischemic stress echocardiography. METHODS: Three hundred seventy-five patients with diabetes (mean age, 68 ± 9 years) with nonischemic dipyridamole stress echocardiography underwent assessment of CFVR of the left anterior descending coronary artery (prospectively) and LVCR with left ventricular force (retrospectively) in a multicenter study...

BACKGROUND: Anthracycline cardiotoxicity can cause significant long-term morbidity in childhood cancer survivors (CCS), but many CCS do not manifest clinical symptoms until adulthood. The aims of this study were to characterize the dynamic myocardial response to exercise of CCS at long-term follow-up by combining semisupine bicycle exercise stress echocardiography with myocardial imaging techniques and to establish whether semisupine bicycle exercise stress echocardiography could identify CCS with abnormal exercise response...

BACKGROUND: Apical transverse motion (ATM) is associated with electromechanical dyssynchrony in adult dilated cardiomyopathy (DCM). Bundle branch block electromechanical dyssynchrony is uncommon in pediatric DCM, but ATM and its association with ventricular function have not been characterized. METHODS: Fifty-six children with DCM were retrospectively studied. Using echocardiography, ATM was assessed visually and by speckle-tracking longitudinal displacement of the interventricular septal and left ventricular (LV) lateral walls in opposite directions...

Fabry disease is an X-linked lysosomal storage disorder that results from a deficiency of α-galactosidase A. Increased left ventricular wall thickness has been the most commonly described cardiovascular manifestation of the disease. However, a variety of other structural and functional abnormalities have also been reported. Echocardiography is an effective noninvasive method of assessing the cardiac involvement of Fabry disease. A more precise and comprehensive characterization of Fabry cardiomyopathy using conventional and novel echocardiographic techniques may lead to earlier diagnosis, more accurate prognostication, and timely treatment...

BACKGROUND: Real-time three-dimensional echocardiography (RT3DE) is a promising method for accurate assessment of left ventricular (LV) volumes and function, however, pediatric reference values are scarce. The aim of the study was to establish pediatric percentiles in a large population and to compare the inherent influence of different evaluation software on the resulting measurements. METHODS: In a multicenter prospective-design study, 497 healthy children (ages 1 day to 219 months) underwent RT3DE imaging of the LV (ie33, Philips, Andover, MA)...

BACKGROUND: Patients with cardiomyopathy (CM) are at increased risk for pulmonary hypertension (PH). Data are lacking on the use of noninvasive PH measures by echocardiography in patients with CM. The aim of this study was to evaluate the correlation between Doppler-derived echocardiographic indices and catheterization-based measurement of pulmonary vascular resistance (PVR) in children and young adults with CM. METHODS: Imaging studies were retrospectively reviewed from pediatric patients with CM who underwent both echocardiography and cardiac catheterization within a 72-hour period...

BACKGROUND: We compared the long-term outcome of subjects without prior cardiac disease who underwent either vasodilator single-photon emission computed tomography (SPECT) or contrast stress-echocardiography (cSE) for suspected coronary artery disease (CAD). METHODS: Subjects who underwent vasodilator SPECT or cSE between 2008 and 2012 for suspected CAD but no history of cardiac disease were included. We retrospectively compared the association of each method with combined all-cause death and nonfatal myocardial infarction and their positive predictive value (PPV) for angiographically obstructive CAD...
