BACKGROUND: Stress echocardiography (SE) has an established role in evidence-based guidelines, but recently its breadth and variety of applications have extended well beyond coronary artery disease (CAD). We lack a prospective research study of SE applications, in and beyond CAD, also considering a variety of signs in addition to regional wall motion abnormalities. METHODS: In a prospective, multicenter, international, observational study design, > 100 certified high-volume SE labs (initially from Italy, Brazil, Hungary, and Serbia) will be networked with an organized system of clinical, laboratory and imaging data collection at the time of physical or pharmacological SE, with structured follow-up information...

The stochastic nature of cavitation implies visualization of the cavitation cloud in real-time and in a discriminative manner for the safe use of focused ultrasound therapy. This visualization is sometimes possible with standard echography, but it strongly depends on the quality of the scanner, and is hindered by difficulty in discriminating from highly reflecting tissue signals in different organs. A specific approach would then permit clear validation of the cavitation position and activity. Detecting signals from a specific source with high sensitivity is a major problem in ultrasound imaging...

BACKGROUND: Deletion in the chromosomal region 22q11 results from the abnormal development of the third and fourth pharyngeal pouches during embryonic life and presents an expansive phenotype with more than 180 clinical features described that involve every organ and system. HISTORY AND SIGNS: A 23-year-old African woman presented for the first trimester echography, which revealed an isolated anechoic structure suggesting a ureteral dilatation. The suspicion of a malposition of great arteries in the second trimester indicated an amniocentesis leading to a diagnosis of 22q11 deletion...

Although interventional devices, such as needles, guide wires, and catheters, are best visualized by X-ray, real-time volumetric echography could offer an attractive alternative as it avoids ionizing radiation; it provides good soft tissue contrast, and it is mobile and relatively cheap. Unfortunately, as echography is traditionally used to image soft tissue and blood flow, the appearance of interventional devices in conventional ultrasound images remains relatively poor, which is a major obstacle toward ultrasound-guided interventions...

A 77-year-old male with many comorbidities underwent off pump coronary artery bypass grafting. A severely atherosclerotic ascending aorta was revealed by preoperative computed tomography(CT) and epiaortic echography during operation. Therefore, V-composite saphenous vein grafting was adopted for non left anterior descending artery (LAD) coronary lesions in addition to left internal thoracic artery-left anterior descending artery bypass grafting. He was discharged with no complications and all grafts were confirmed to be patent by postoperative CT...

Recent developments in ultrasound imaging and ultrasound contrast agents (UCAs) improved diagnostic confidence in echography and set into motion their combined use as a tool for drug delivery and therapeutic monitoring. Non-invasive, precise and targeted delivery of drug molecules to pathological tissues by employing different mechanisms of drug release is becoming feasible. Areas covered: We sought to describe: the nature and features of UCAs; outline current contrast-specific imaging modes; before describing a variety of strategies for using ultrasound and microbubbles as a drug delivery system...

BACKGROUND: Ultrasound guidance for venous catheter placement requires the use of both hands. An accurate and stable ultrasound image is fundamental for obtaining good quality images, consequently permitting accurate needle placement. We hypothesized that the dominant hand could be used to perform echography, leaving the non-dominant hand available for peripheral venous catheter (PVC) insertion. METHODS: Prospective, open-label, randomized, crossover study. Group 1 inserted the PVC with the dominant hand, and held the probe with the non-dominant hand in a first series of 20 insertions, and vice versa in a second series of 20 insertions performed 11days later...

Patients with asymptomatic heart failure (HF; stage A and B) are characterized by maladaptive left ventricular (LV) remodeling. Classic 4-group classification of remodeling considers only LV mass index and relative wall thickness as variables. Complex remodeling classification (CRC) includes also LV end-diastolic volume index. Main aim was to assess the prognostic impact of CRC in stage A and B HF. A total of 1,750 asymptomatic subjects underwent echocardiographic examination as a screening evaluation in the presence of cardiovascular risk factors...

This Letter proposes an end-to-end mobile tele-echography platform using a portable robot for remote cardiac ultrasonography. Performance evaluation investigates the capacity of long-term evolution (LTE) wireless networks to facilitate responsive robot tele-manipulation and real-time ultrasound video streaming that qualifies for clinical practice. Within this context, a thorough video coding standards comparison for cardiac ultrasound applications is performed, using a data set of ten ultrasound videos. Both objective and subjective (clinical) video quality assessment demonstrate that H...

BACKGROUND: An appropriate diagnostic process is crucial for managing patients with acute heart failure (AHF) in emergency department (ED). Our study aims to describe the characteristics and therapeutic management of patients admitted to the ED for dyspnea suspected to have AHF, their in-hospital pathway of care and their in-hospital outcome. METHODS: Consecutive patients admitted in 26 French ED for dyspnea suspected to be the consequence of AHF, prior to in hospital diagnostic test, were prospectively included at the time of their admission in the DeFSSICA Survey...

BACKGROUND AND AIMS: Circulating Angiotensin Converting Enzyme 2 (ACE2) activity in chronic kidney disease (CKD) patients without previous history of cardiovascular disease (CVD) has been associated with classical risk factors (older age, diabetes and male gender). Furthermore, silent atherosclerosis has been described as a pathological link between CKD and CVD. We analyzed baseline ACE2 activity in non-dialysis CKD stages 3-5 (CKD3-5) patients as a biomarker of renal progression, silent atherosclerosis and CV events after 2 years of follow-up...

Ventricular septal defect (VSD) has a relatively non-aggressive clinical course; either spontaneous closure or causing congestive heart failure treatable with surgical intervention. We present two autopsy cases of sudden infant deaths from clinically undiagnosed VSDs. Case 1 was an 18-day-old boy. As the deceased coughed and became limp after feeding, he was carried to a hospital. Heart murmur was not auscultated there, so he was brought back to home. He presented severe dyspnea and then he was pronounced dead the next day...

A 57-year-old woman with Marfan syndrome had undergone the surgical treatment for pectus excavatum at 15 years of age. She had since been screened regularly by computed tomography(CT) to detect any vascular diseases. CT demonstrated a left subclavian arterial aneurysm at 55 years of age. It enlarged to a diameter of 32 mm, and surgical treatment was performed. The subclavian artery and the aneurysm were identified by echography in order to locate the exact sites of supraclavicular and subclavicular skin incisions...

Hyperthyroidism and thyroid storm affect cardiac circulation in some conditions. Several factors including trauma can induce thyroid storms. We herein describe the case of a 57-year-old woman who experienced a thyroid storm and exacerbation of acute heart failure on thyroid echography. She initially demonstrated a good clinical course after medical rate control for atrial fibrillation; however, thyroid echography for evaluating hyperthyroidism led to a thyroid storm and she collapsed. A multidisciplinary approach stabilized her thyroid hormone levels and hemodynamics...
