OBJECTIVES: To assess the natural history and outcome of fetal pulmonary stenosis [PS] detected at 14 to 16 weeks gestation. METHODS: This is a retrospective study, in the years 2004-2015, with serial follow up during pregnancy. Patients referred for complete early fetal ultrasound including all fetal systems and a fetal echocardiogram. Ninety seven percent of the women were low risk, and 3% had risk factors such as maternal type 1 diabetes mellitus, exposure to teratogenic drugs or anomalies in previous pregnancies or in other family members...

BACKGROUND: Echocardiographic screening for rheumatic heart disease (RHD) can identify individuals with subclinical disease who could benefit from antibiotic prophylaxis. However, most settings have inadequate resources to implement conventional echocardiography and require a feasible, accurate screening method. We aimed to investigate the accuracy of screening by non-expert operators using focused cardiac ultrasound (FoCUS). METHODS: In this prospective study of diagnostic accuracy, we recruited schoolchildren aged 5 to 15 years in Fiji to undergo two blinded tests...

The cohort of long-term survivors of heart transplant is expanding, and the assessment of these patients requires specific knowledge of the surgical techniques employed to implant the donor heart, the physiology of the transplanted heart, complications of invasive tests routinely performed to detect graft rejection (GR), and the specific pathologies that may affect the transplanted heart. A joint EACVI/Brazilian cardiovascular imaging writing group committee has prepared these recommendations to provide a practical guide to echocardiographers involved in the follow-up of heart transplant patients and a framework for standardized and efficient use of cardiovascular imaging after heart transplant...

BACKGROUND: Frequently, hospitalized patients are referred for transthoracic echocardiograms. The availability of a pocket mobile echocardiography device that can be incorporated on bedside rounds by cardiologists may be a useful and frugal alternative. METHODS: This was a cross-sectional study designed to compare the accuracy of pocket mobile echocardiography images with those acquired by transthoracic echocardiography in a sample of hospitalized patients. Each patient referred for echocardiography underwent pocket mobile echocardiography acquisition and interpretation by a senior cardiology fellow with level II training in echocardiography...

BACKGROUND: Serious cardiac valve disease and left ventricular hypertrophy occur in most untreated older children with severe mucopolysaccharidosis type I. Although it is assumed that early intervention prevents these processes, evaluation of cardiac findings in these infants has not yet been reported. METHODS: We reviewed echocardiograms of 13 untreated infants < 1 year of age with severe mucopolysaccharidosis type I who had undergone evaluation for hematopoietic cell transplantation...

BACKGROUND: Aortic root dilation, dissection and rupture are major clinical problems in Marfan syndrome (MFS). Although β-blockers remain the standard of preventive treatment, preliminary results from animal studies and a selected group of severely affected MFS children show significant benefit from treatment with losartan, an angiotensin II receptor blocker with TGF-β inhibiting potential. Large-scale human trials are now needed to confirm these results. This trial aims to evaluate the combined effect of both drugs...

Valvular cardiomyopathy can present a diagnostic challenge in the absence of overt cardiac symptoms. This report describes the case of a 46-year-old woman who presented with acute peritonitis associated with vomiting and abdominal distension. Subsequent abdominal computed tomography and ultrasound revealed bibasal pleural effusions, ascites, and normal ovaries. An echocardiogram revealed that all cardiac chambers were dilated with a global decrease in contractility and severe mitral, tricuspid, and aortic regurgitation...

OBJECTIVE: The traditional physical examination of the heart is relatively inaccurate. There is little information regarding whether cardiac hand-carried ultrasound performed by noncardiologists adds to the accuracy of physical examinations. The purpose of this study was to determine whether hand-carried ultrasound can add to the accuracy of hospitalists' cardiac physical examinations. METHODS: During a focused training program in hand-carried echocardiography, 10 hospitalists performed cardiac examinations of 354 general medical inpatients first by physical examination and then by hand-carried ultrasound...

BACKGROUND: Diagnosis of pulmonary arterial hypertension (PAH) relies on Doppler measurement of pulmonic and tricuspid regurgitation (TR). However, these are not always detectable. HYPOTHESIS: Tissue Doppler imaging (TDI), a novel noninvasive ultrasound technique, provides indirect but sensitive and specific assessment of elevated systolic pulmonary artery pressure (SPAP) in dogs. ANIMALS: One hundred and five dogs with TR. METHODS: Prospective observational study...

PURPOSE: The purpose of this study was to determine the sensitivity and specificity of arterial Doppler findings of aortic regurgitation to assess if the amplitude of changes of Doppler tracings can accurately quantify the degree of regurgitation. PATIENTS AND METHODS: We analysed and compared the arterial Doppler tracings and echocardiograms of 250 patients. RESULTS: Even if the obvious pitfall of vascular stenoses is avoided, the global sensitivity of arterial Doppler findings for aortic regurgitation remains weak (30%)...

In the current study, we describe an adult patient with torrential aortic regurgitation due to an aortic dissection flap interfering with aortic cusp motion, in whom a transesophageal echocardiogram with the probe positioned in the upper esophagus and transpharyngeal ultrasound examination demonstrated prominent reversed flow throughout diastole in the left subclavian, left vertebral, left common carotid, and left internal carotid arteries. Another unique finding was the demonstration of aortic valve leaflets held in the fully opened position in diastole by the dissection flap as it prolapsed into the left ventricular outflow tract, dramatically documenting the mechanism of torrential aortic regurgitation in this patient...

The advances in Doppler echocardiography, like last year, concern the technology, the indications and the description of the natural history of cardiovascular diseases. The year 2000 will be remembered for the development of portable echocardiographs with two-dimensional and Doppler capabilities but without M mode, pulsed or continuous Doppler. These instruments weigh less than 3 kg and may be used at the bedside; however, problems of training personnel, reimbursement and availability of equipment remain. Myocardial contrast echocardiography has been the subject of many publications which validate continuous intravenous infusion of different contrast agents, which, coupled with techniques of image processing, suggest that quantification of regional myocardial perfusion at rest or during physiological or pharmacological stress may not be far off...

Recent studies have suggested that intermediate-frequency M-Mode transthoracic echocardiographic imaging is a promising method for evaluating the left ventricle in transgenic mice. However, there is a paucity of data regarding two-dimensional (2-D) echocardiography and cardiac Doppler echocardiography in this model. Therefore we studied 15 mice (body weights 38 to 65 gm) with an ultrasound system equipped with a 9 MHz transducer. M-mode, 2-D, pulsed, and color-flow Doppler studies were performed. Mean +/- SD for septal, posterior wall, and left ventricular cavity dimensions at end diastole were the following: M-mode: 1...

The increasing popularity of Doppler echocardiography in recent years has stemmed from the combination of Doppler with two-dimensional echocardiography, and from the Doppler capability for flow velocity measurement. In the past decade, Doppler instrumentation has evolved from single probe A- and M-mode systems with non-quantitative Doppler output, into multi-faceted instruments combining two-dimensional echo, M-mode echo, with both pulsed and continuous wave Doppler. In the field of pediatric cardiology, quantitative Doppler applications have proven most useful in noninvasive measurement of the severity of obstruction at aortic and pulmonic valves, and across pulmonary artery bands...
