INTRODUCTION: Percutaneous left atrial appendage (LAA) occlusion is an emerging treatment option for patients with non-valvular atrial fibrillation who cannot tolerate oral anticoagulation. The Watchman device (Boston Scientific Corporation, Natick, MA, USA) is deployed at the ostium of the LAA, and an appropriately sized device is critical for successful occlusion. However, standardized imaging protocols for device sizing have not been established. OBJECTIVES: We investigated the clinical utility of a standardized imaging protocol, with pre-procedural multi-detector cardiac computed tomography (MDCT), and intra-procedural transesophageal echocardiography (TEE), for Watchman device sizing...

Medical imaging has advanced enormously over the last few decades, revolutionizing patient diagnostics and care. At the same time, additive manufacturing has emerged as a means of reproducing physical shapes and models previously not possible. In combination, they have given rise to 3-dimensional (3D) modeling, an entirely new technology for physicians. In an era in which 3D imaging has become a standard for aiding in the diagnosis and treatment of cardiac disease, this visualization now can be taken further by bringing the patient's anatomy into physical reality as a model...

The incidence of blunt chest trauma (BCT) is greater than 15% of all trauma admissions to the emergency departments worldwide and is the second leading cause of death after head injury in motor vehicle accidents. The mortality due to BCT is inhomogeneously described ranging from 9% to 60%. BCT is commonly caused by a sudden high-speed deceleration trauma to the anterior chest, leading to a compression of the thorax. All thoracic structures might be injured as a result of the trauma. Complex cardiac arrhythmia, heart murmurs, hypotension, angina-like chest pain, respiratory insufficiency or distention of the jugular veins may indicate potential cardiac injury...

BACKGROUND: Asystole (ASY) and pulseless electrical activity (PEA) are increasing and ventricular fibrillation (VF) or ventricular tachycardia (VT) declining as presenting rhythms of sudden cardiac arrest (SCA). Since there is limited information on possible differences in the etiology of underlying structural heart disease, we analyzed the clinical and/or autopsy findings of victims with ASY, PEA or VT/VF. METHODS: All SCA cases with recorded ASY, PEA or VT/VF occurring after onset of witnessed collapse were analyzed by the emergency personnel between the years 2007-2012 within the Oulu University Hospital area...

Cardiovascular disease remains a worldwide public health issue. As fructose consumption is dramatically increasing, it has been demonstrated that a fructose-rich intake would increase the risk of cardiovascular disease. In addition, emerging evidences suggest that low concentration alcohol intake may exert a protective effect on cardiovascular system. This study aimed to investigate whether low-concentration alcohol consumption would prevent the adverse effects on cardiovascular events induced by high fructose in mice...

Mitral regurgitation (MR) is a major cause of cardiovascular morbidity and mortality. MR is classified as primary (organic) if it is due to an intrinsic valve abnormality, or secondary (functional) if the etiology is because of remodeling of left ventricular geometry and/or valve annulus. Transthoracic echocardiography (TTE) is the initial modality for MR evaluation. Parameters used for the assessment of MR include valve structure, cardiac remodeling, and color and spectral Doppler. Quantitative measurements include effective regurgitant orifice area, regurgitant volume, and regurgitant fraction...

Pericardial effusion of various sizes is a quite common clinical finding, while its progression to effusive-constrictive pericarditis occurs in about 1.4-14% of cases. Although available evidence on prevalence and prognosis of this rare pericardial syndrome is poor, apparently a considerable proportion of patients conservatively managed has a spontaneous resolution after several weeks. A 61-year-old female presented to our emergency department reporting fatigue, effort dyspnea and abdominal swelling. The echocardiography showed large pericardial effusion with initial hemodynamic impact, so she underwent a pericardiocentesis with drainage of 800-850cm(3) of exudative fluid, on which diagnostic investigations were undertaken: possible viral and bacterial infections, medical conditions, iatrogenic causes, neoplastic and connective tissue diseases were all excluded...

Nowadays, reasonable transcatheter tricuspid valve (TV) interventions are emerging as therapeutic options for functional tricuspid regurgitation (TR). The preprocedural planning is based on a multimodality imaging approach, which aims to (1) define the mechanisms of TR, (2) characterize TV morphology, (3) analyze the anatomic relationship between the TV apparatus and other structures, and (4) determine the size of the tricuspid annulus and vena cavae. Intraprocedural guidance is based mainly on transesophageal echocardiography (seldom transthoracic) and fluoroscopy, with the recent introduction of fusion imaging...

A 74-year-old male presented to the emergency department 46 days after undergoing an aortic valve replacement. He presented with nonspecific symptoms developed over the previous 15 days, with a new onset of a systolic panfocal murmur. Echocardiography revealed a great vegetation measuring 15 mm by 23 mm causing a severe obstruction of the bioprosthesis. The patient underwent an emergency surgical procedure due to his hemodynamic unsteadiness. During the procedure, we noted an obstruction of the left ventricle outflow tract with pseudoaneurysm of the aortomitral continuity...

BACKGROUND: Pulmonary embolism can be difficult to diagnose, particularly in those who are hemodynamically unstable and cannot be imaged to confirm the diagnosis. Echocardiography can allow for rapid assessment of patients in shock, but requires adequate transthoracic windows to obtain clinically useful information. Emergency physician-performed transesophageal echocardiography (TEE) may be a useful tool when transthoracic echocardiography fails.

Heart failure is a rare cause of wheezing and may develop into a critical condition in children. Few cases report patients with heart failure, secondary to dilated cardiomyopathy, with high fever. A 23-month-old girl visited the emergency department with high fever, cough, first wheezing episode, chest retraction and tachycardia. The chest X-ray revealed consolidation on the left lower lung field; the cardiothoracic ratio was 60%. She was diagnosed with bronchial asthma triggered by pneumonia, which remained unchanged during four visits...
