A 67-year-old man presented with 3 months of exertional dyspnoea and 1 week of oedema. Examination revealed elevated neck veins, pulsus paradoxus, muffled heart sounds, decreased breath sounds and pedal oedema. Transthoracic echocardiogram (TTE) demonstrated cardiac tamponade, and chest X-ray showed pleural effusion. Pericardiocentesis, thoracocentesis, laboratory investigations and CT did not elucidate an underlying aetiology. Three weeks later, he presented with recurrent cardiac tamponade and pleural effusion...

Left ventricular volume-time curves (VTCs) provide hemodynamic data, and may help clinical decision making. The generation of VTCs using echocardiography, however, is time-consuming and prone to inter-operator variability. In this study, we used a new non-invasive, operator-independent technique, the hemodynamic cardiac profiler (HCP), to generate VTCs. The HCP, which uses a low-intensity, patient-safe, high-frequency applied AC current, and 12 standard ECG electrodes attached on the thorax in a pre-defined pattern, was applied to five young healthy volunteers, five older healthy volunteers, and five patients with severe mitral regurgitation...

A 10-year-old well and asymptomatic female was referred for screening of acute right ventricular dilatation (ARVD) as she had an elder brother diagnosed with ARVD whom died of sudden cardiac death. Electrocardiography (ECG), transthoracic echocardiography (TTE) and cardiac magnetic resonance imaging (CMR) were performed. Results of these investigations were suggestive of ARVD. Despite being a rare cardiac disease and largely unrecognised in children and young adult population, ARVD is an important cause of ventricular arrhythmias in this group of patients and is one of the causes of sudden cardiac death (SCD) in this population...

INTRODUCTION: The mitral valve area (MVA) poorly reflects the hemodynamic status of (MS). In this study, we compared the MVA with mitral valve resistance (MVR) with regard to the determination of hemodynamic consequences of MS and the immediate outcomes of percutaneous balloon mitral valvuloplasty (PBMV). METHODS: In a prospective study, 36 patients with severe rheumatic MS with left ventricular ejection fraction (LVEF) >50% were evaluated. They underwent transthoracic echocardiography (TTE) and catheterization...

BACKGROUND: Transthoracic echocardiography (TTE) and computerized axial tomography (CT) are complementary imaging techniques. It is possible that a combination of the two may offer a better way of identifying pulmonary hypertension (PH) than either one alone. OBJECTIVES: To determine the diagnostic accuracy of TTE combined with chest CT in pulmonary hypertension. METHODS: We performed a retrospective review of consecutive patients who had undergone TTE, CT and right heart catheterization (RHC) between 7/1/2008 and 6/30/2012...

BACKGROUND: Campylobacter spp. are a common cause of mostly self-limiting enterocolitis. Although rare, pericarditis and myopericarditis have been increasingly documented as complications following campylobacteriosis. Such cases have occurred predominantly in younger males, and involved a single causative species, namely Campylobacter jejuni. We report the first case of myopericarditis following Campylobacter coli enterocolitis, with illness occurring in an immunocompetent middle-aged female...

BACKGROUND: The aim of this study was to assess the accumulation pattern of 18F-FDG in fasting patients with takotsubo cardiomyopathy (TTC) and to correlate the results with perfusion scintigraphy and echocardiography. METHODS: 18 consecutive patients with TTC were identified by clinical symptoms, cardiac catheterization, and echocardiography. Coronary angiography (CA) and transthoracic echocardiography (TTE) were performed on the day of the onset of symptoms. An assessment of myocardial perfusion (99mTc-MIBI) and glucose metabolism (18F-FDG) was performed within 18 days...

BACKGROUND: The appropriateness of repeat transthoracic echocardiography (TTE) for stable heart failure (HF) is based on timing of the follow-up examination, but this lacks scientific support. We sought the association of routine follow-up TTE on survival and readmission in stable HF. METHODS: Patients with HF were selected from consecutive HF admissions from 2008 to 2012. Groups were divided into: no follow-up TTE; routine <1year with no change in status ("rarely appropriate"), ≥1year follow-up with no change in status ("maybe appropriate") and TTE due to change in clinical status ("appropriate")...

A 69-year-old man was admitted after syncope followed with chest pain and signs of cardiac tamponade. He had undergone permanent dual-chamber pacemaker implantation 3 weeks earlier. Transthoracic echocardiography (TTE) confirmed a pericardial effusion, and urgent pericardial drainage was performed. Right ventricular perforation caused by active-fixation (screw-in) lead was verified by multislice computed tomography. The lead was extracted under fluoroscopy and bedside TTE monitoring in the operating room with cardiothoracic surgery backup...

BACKGROUND: The intended physiologic response to a fluid bolus is an increase in stroke volume (SV). Several ultrasound (US) measures have been shown to be predictive. The best measure(s) in critically ill surgical patients remains unclear. METHODS: This is a prospective observational study in critically ill surgical patients receiving a bolus of crystalloid, colloid or blood. A transthoracic echocardiogram (TTE) was performed before (pre-TTE) and after. A positive volume response (+VR) was defined as a ≥15% increase in SV...

OBJECTIVES: This study hypothesized that the presence of residual mitral regurgitation (MR) post-continuous flow (CF) left ventricular assist device (LVAD) implantation based on quantitative assessment would be negatively associated with right ventricular (RV) size and function and clinical outcomes. BACKGROUND: MR is associated with elevated left atrial pressure, secondary pulmonary hypertension and RV dysfunction. Implantation of a LVAD leads to mechanical unloading of the left ventricle and generally improves MR...

Left ventricular pseudoaneurysm (LVPA) after mitral valve replacement (MVR) is a rare condition. The diagnosis of LVPA may be difficult, and for accurate diagnosis, two-dimensional (2D) transthoracic echocardiography (TTE) should be used in combination with other imaging modalities such as multiple detector computed tomography (MDCT) and three-dimensional (3D) TTE. Herein is presented a late type of post-MVR pseudoaneurysm in a 72-year-old female who was admitted to the authors' emergency department with complaints of dyspnea...

Li-S batteries are a promising next-generation battery technology. Due to the formation of soluble polysulfides during cell operation, the electrolyte composition of the cell plays an active role in directing the formation and speciation of the soluble lithium polysulfides. Recently, new classes of electrolytes termed "solvates" that contain stoichiometric quantities of salt and solvent and form a liquid at room temperature have been explored due to their sparingly solvating properties with respect to polysulfides...

Aortic valve infective endocarditis (IE) can be complicated with severe aortic regurgitation (AR) jet-related lesions such as vegetations, pseudoaneurysms, aneurysms or perforations on the anterior mitral leaflet. Herein is reported the case of a 69-year-old male with culture-negative aortic valve endocarditis complicated with aortic valve perforations resulting in severe and eccentric AR and an AR jet-related ventricular septal defect (VSD). Neither transthoracic echocardiography (TTE) nor two-dimensional transesophageal echocardiography (2D-TEE) were unable to clearly discriminate an aorto-right ventricular fistula from a VSD...
