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 11 days 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 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...

OBJECTIVE: The question whether arterial stiffness in hypertension is increased solely because of increased arterial pressure is not solved. Because measurement of arterial stiffness is highly dependent on measurement of blood pressure (BP), the development of methods independent of BP is necessary for clarifying this question. Ultrafast echography (UFE, Supersonic Imagine, Aix en Provence, France) makes use of very fast sampling rate (up to 10 kHz), so transient events such as pressure wave arrival can be tracked...

Evaporation of droplets of three pure liquids (water, 1-butanol, and ethanol) and four binary solutions (5 wt % 1-butanol-water-based solution and 5, 25, and 50 wt % ethanol-water-based solutions) deposited on hydrophobic silicon was investigated. A drop shape analyzer was used to measure the contact angle, diameter, and volume of the droplets. An infrared camera was used for infrared thermal mapping of the droplet's surface. An acoustic high-frequency echography technique was, for the first time, applied to track the alcohol concentration in a binary-solution droplet...

BACKGROUND: Cyst of Nuck is an infrequent disease originated in the inadequate obliteration of the processus vaginalis during the embrionary life of the woman. Clinically usually appears as a slowly growth inguinal tumor, painless, smooth, soft, fluctuant and irreducible. Differential diagnosis must include inguinal hernia and other etiologies of inguinal tumor, for which echography is the main diagnostic test. Treatment consists on surgical extirpation and local reparation. It is exposed a case of a patient with cyst of Nuck clinically typical...

Distal embolization of a fractured indwelling central catheter is a rare complication. The pinch-off syndrome (POS) should be known, prevented and early detected. We present a case in which further radiological exams were required to find the fragmented catheter with an atypical migration, requiring local surgery for removing. After chest and abdominal CT scan, neck X-ray, and heart echography, the catheter was found on the lower limbs X-ray on the internal side of right knee corresponding to a location of saphenous vein...

OBJECTIVES: Prostate cancer (PCa) is the most common form of cancer among men in the US and the second most common cause of death. It has been observed that an increasing number of newly diagnosed patients exhibit low-risk features and that over-treatment with radical prostatectomy is a growing problem. The feasibility of focal therapy as an organsparing alternative, however, depends on the reliability of imaging techniques to identify, localize and monitor clinically relevant PCa lesions...

Diagnosis of giant-cell arteritis (GCA) is challenging in the absence of cardinal cranial symptoms/signs. We aimed to describe the clinical presentation, diagnostic process, and disease course of GCA patients without cranial symptoms, and to compare them to those of patients with typical cranial presentation. In this retrospective multicenter study, we enrolled patients with GCA who satisfied at least 3 of the 5 American College of Rheumatology criteria for GCA, or 2 criteria associated with contributory vascular biopsy other than temporal artery biopsy or with demonstration of large-vessel involvement; underwent iconographic evaluation of large arterial vessels (aortic CT scan or a positron emission tomography with F-fluorodeoxyglucose combined with computed tomography (FDG-PET/CT) scan or cardiac echography combined with a large-vessel Doppler) at diagnosis...

Echographic examination for leg vein thromboembolism was carried out in 123 patients scheduled for thoracic surgery. Preventive measures for thromboembolism were conducted after the risk assessment. Echography was done after surgery in 72 cases, most of which were cases of lung malignant tumors, and thromboembolism was detected in 4 cases. Thus, the incidence rate of venous thromboembolism was 5.6%( 4/72). There was no patients who developed pulmonary thromboembolism during the examination period, suggesting reasonable risk assessment and preventive measures in our procedure...

Automated ultrasound breast imaging would overcome most of the limitations that precludes conventional hand-held echography to be an effective screening method for breast cancer diagnosis. If a three dimensional (3D) ultrasound dataset is acquired without manual intervention of the technician, repeatability and patient follow-up could be improved. Furthermore, depending on the system configuration, resolution and contrast could be enhanced with regard to conventional echography, improving lesion detectability and evaluation...
