Primary cardiac angiosarcomas are frequently found at a large size with infiltration into the adjacent heart structure owing to their asymptomatic characteristics until an advanced stage. Therefore, extensive resection is often required to achieve a good prognosis. We herein report a case of entire circumferential resection of the right atrium surrounded by angiosarcoma and excellent three-dimensional reconstruction of the right atrium.

BACKGROUND: Functional mitral regurgitation (MR) can occur in patients with atrial fibrillation (AF) despite having preserved left ventricular (LV) systolic function. This MR is known as atrial functional MR. The aim of this study was to clarify the mechanism of atrial functional MR using real-time three-dimensional transesophageal echocardiography (3DTEE). METHODS: Sixty patients underwent transthoracic echocardiography and 3DTEE: 16 patients with AF and significant non-organic MR and preserved LV ejection fraction (>50%) constituted the AF-MR group, 20 patients with AF and no significant MR formed the AF-NSMR group, and 24 normal subjects comprised the control group...

PURPOSE: Measurement of inferior vena cava collapsibility (cIVC) by point-of-care ultrasound (POCUS) has been proposed as a viable, non-invasive means of assessing fluid responsiveness. We aimed to determine the ability of cIVC to identify patients who will respond to additional intravenous fluid (IVF) administration among spontaneously breathing critically-ill patients. METHODS: Prospective observational trial of spontaneously breathing critically-ill patients...

Renal angiomyolipomas are the most common renal mesenchymal tumors. While classic angiomyolipomas are benign, there are a number of other subtypes. Epithelioid variants are potentially malignant and may be indistinguishable from renal cell carcinoma on imaging. We present a 52-year-old woman who underwent left nephrectomy for an aggressive-appearing malignant renal epithelioid angiomyolipoma. At 6 months postoperatively, restaging FDG PET/CT demonstrated a hypermetabolic left adrenal mass extending to the left adrenal vein, left renal vein, inferior vena cava, and right atrium (SUVmax = 12)...

PURPOSE: Hemodialysis patients have extremely increased cardiovascular mortality. The coronary artery calcification score (CACS) in uremic patients receiving hemodialysis reflects the severity of atherosclerotic vascular disease and predicts the cardiovascular events. In cardiac conditions, left atrial (LA) size has a prognostic importance. In this study, relationship between coronary artery calcification and left atrial size was investigated. METHODS: This was a cross-sectional study involving 32 hemodialysis patients (16 females, 16 males; mean age, 52...

Left atrial (LA) enlargement and dysfunction are markers of chronic diastolic dysfunction and an important predictor of adverse cardiovascular and cerebrovascular outcomes. Accordingly, accurate quantification of left atrial volume (LAV) and function is needed. In routine clinical cardiovascular magnetic resonance (CMR) imaging the biplane area-length method (Bi-ALM) is frequently applied due to time-saving image acquisition and analysis. However, given the varying anatomy of the LA we hypothesized that the diagnostic accuracy of the Bi-ALM is not sufficient and that results would be different from a precise volumetric assessment of transversal multi-slice cine images using Simpson's method...

Long-term cessation of oral anticoagulation (OAC) following successful catheter or surgical ablation of atrial fibrillation (AF) is debated. Usually, in the presence of sinus rhythm at serial ECG recordings, the CHADS2, CHA2DS2VASc, and HAS-BLED scores are adopted to guide decision regarding OAC management. Areas covered: The safety of OAC cessation in patients without recurrent AF but with historically elevated risk for thromboembolism remains largely unknown. Taking the cue from two clinical cases, we provide an updated summary of the latest evidence regarding how to manage OAC after a successful atrial fibrillation ablation...

Pulmonary veins isolation (PVI) by radiofrequency (RF) ablation is currently an established treatment for symptomatic, drug-resistant paroxysmal atrial fibrillation. Although the effectiveness of the therapy has been clearly demonstrated, success rate after a single procedure is still sub-optimal. The main reason for recurrences after PVI is electrical pulmonary vein-atrium reconnection. In order to increase the likelihood of permanent PVI, the creation of a transmural, durable lesion is mandatory. The main determinants of lesion size and transmurality are power, stability, duration and contact-force during RF application...

Background Computed tomography (CT) of the left atrium (LA) is performed prior to pulmonary vein isolation (PVI) to improve success of circumferential ablation for atrial fibrillation. The ablation procedure itself exposes patients to substantial radiation doses, therefore radiation dose reduction in pre-ablational imaging is of concern. Purpose To assess and compare diagnostic performance of low-radiation dose preprocedural CT in patients scheduled for PVI using two types of reconstruction algorithms. Material and Methods Forty-six patients (61 ± 10 years) scheduled for PVI were enrolled in this study irrespective of body-mass-index or cardiac rhythm at examination...

BACKGROUND: In recent years cardioversion of atrial fibrillation has become a routine procedure, enabling symptomatic functional improvement in most cases. However, some patients develop complications after cardioversion. Identifying these individuals is an important step toward improving patient outcome. OBJECTIVES: To characterize those patients who may not benefit from cardioversion or who may develop complications following cardioversion. METHODS: We retrospectively analyzed 186 episodes of cardioversion in 163 patients with atrial fibrillation who were admitted to our cardiology department between 2008 and 2013 based on their clinical and echocardiographic data...

Heart failure (HF) is a pressing health concern as the expense of hospitalization financially burdens the health care system. Hemodynamic monitoring has the potential to detect increases in intracardiac filling pressures weeks before clinical deterioration; hence, preliminary findings of volume overload with the use of these devices may prevent the progression of disease and lead to a reduction in HF-associated hospitalizations. We extensively searched PubMed, Ovid SP, Embase, and Cochrane databases to identify all the possible studies that assess the effect of hemodynamic monitoring on hospitalizations in HF patients...

The term Mahaim conduction is conventionally used to describe decrementally conducting connections between the right atrium or the AV node and the right ventricle in or close to the right bundle branch. Although such pathways are rare, their unique properties make their diagnosis and treatment cumbersome. In this article we review the published evidence, and discuss the electrocardiographic and electrophysiological characteristics as well as the anatomy and origin of these fibres.
