Transthoracic echocardiography ( TTE transthoracic echocardiography ) is a critical tool in the field of clinical cardiology. It often serves as one of the first-line imaging modalities in the evaluation of cardiac disease owing to its low cost, portability, widespread availability, lack of ionizing radiation, and ability to evaluate both anatomy and function of the heart. Consequently, a large majority of patients undergoing a cardiac computed tomography (CT) or magnetic resonance (MR) imaging examination will have a TTE transthoracic echocardiography available for review...

REVIEW
Arash Aryana, André d'Avila
Over the last two decades, epicardial catheter ablation has evolved into a practical approach for treatment of ventricular tachycardia (VT). There are certain considerations when performing this procedure. First, presence of epicardial fat can diminish peak-to-peak electrogram amplitude and also impede radiofrequency energy delivery. Hence, epicardial VT ablation should be performed with cooled-tip radiofrequency using reduced irrigation flow within a relatively 'dry' pericardial milieu. Furthermore, catheter orientation is key when performing epicardial ablation...

BACKGROUND: Little data currently exist supporting the correlation of socioeconomic status (SES) to markers of subclinical coronary atherosclerosis. The main aim was to investigate the relationship of SES measured by economic status and educational level with coronary artery calcification (CAC) and pericardial fat volume (PFV) assessed by multi-detector CT (MDCT). METHODS: Two hundred twenty consecutive patients with suspected coronary artery disease who underwent 64-slice MDCT angiography for assessment of coronary atherosclerosis were recruited between January 2014 and March 2015...

Surgical treatment of mycotic aneurysm of the thoracic aorta is challenging because contamination from surrounding tissues may occur even after complete debridement with a prosthetic graft replacement of the aneurysm. This study describes the simple but very useful technique of using a pericardial fat flap to protect the prosthetic graft from reinfection.

BACKGROUND: The pathophysiology of acute pericarditis remains largely unknown, and biomarkers are needed to identify patients susceptible to complications. As adipose tissue has a pivotal role in cardiovascular disease pathogenesis, we hypothesized that quantification of epicardial fat volume (EFV) provides prognostic information in patients with acute pericarditis. MATERIALS AND METHODS: Fifty (n = 50) patients with first diagnosis of acute pericarditis were enrolled in this study...

BACKGROUND: South Asians have a low body mass index and high prevalence of cardiovascular disease (CVD) relative to other racial/ethnic groups. Radiographically detected ectopic fat distribution is better associated with CVD than body mass index. We assessed whether differences in ectopic fat depots explained differences in the prevalence/severity of coronary artery calcium (CAC), a predictor of incident CVD events, among South Asians compared with other racial/ethnic groups. METHODS AND RESULTS: We examined the associations of radiographically detected visceral, intermuscular, intrahepatic, and pericardial fat with CAC among adults without baseline CVD...

Importance: The natural history of hypertrophic cardiomyopathy (HCM) is complex and may include progressive heart failure and severe left ventricular dysfunction. When disease progression is abrupt, however, other coexisting diseases should be ruled out. This may be difficult in the case of amyloidosis, which classically mimics HCM. Results: We present an example of severe clinical deterioration in a patient with HCM due to superimposed amyloid light-chain amyloidosis...

INTRODUCTION: Visceral adipose tissue is a known important risk factor for coronary artery disease (CAD). While some studies have suggested relationship between epicardial fat thickness (EFT) and CAD, there are no adequate studies for pericardial fat thickness (PFT). The aim of this study was to determine the association of EFT and PFT with CAD. METHODS: This cross-sectional study was conducted on patients who were candidates for elective coronary artery angiography, referred to Emam Reza Hospital, Mashhad, Iran during Jan 2014-2016...

BACKGROUND: Point-of-care ultrasonography (POCUS) is a widely used tool in emergency and critical care settings, useful in the decision-making process as well as in interventional guidance. While having an impressive diagnostic accuracy in the hands of highly skilled operators, inexperienced practitioners must be aware of some common misinterpretations that may lead to wrong decisions at the bedside. OBJECTIVES: This article provides a revision list of common POCUS misdiagnoses usually found in practice and offers useful tips to recognize and avoid them...

Obesity, the major cause of the current global epidemic of type 2 diabetes (T2D), induces insulin resistance in peripheral insulin target tissues. Several mechanisms have been identified related to cross-talk between adipose tissue, skeletal muscle and liver. These mechanisms involve both increased free fatty acid release and altered secretion of adipokines from adipose tissue. A major determinant of metabolic health is the ability of subcutaneous adipose tissue (SAT) to store excess fat rather than allowing it to accumulate in ectopic depots including liver (i...

Obesity is associated with increased risk of developing atrial fibrillation (AF). Different fat depots may have differential associations with cardiac pathology. We examined the longitudinal associations between pericardial, intrathoracic, and visceral fat with incident AF. We studied Framingham Heart Study Offspring and Third-Generation Cohorts who participated in the multidetector computed tomography substudy examination 1. We constructed multivariable-adjusted Cox proportional hazard models for risk of incident AF...

INTRODUCTION: Adiposity has been associated with atherosclerosis in clinical studies. However, few autopsy studies have investigated this association, and they had only examined the coronary artery disease. Moreover, most studies had small sample sizes and were limited to middle-aged or young adults. Our aim is to investigate the association between adiposity and systemic atherosclerosis in an autopsy study. METHODS AND ANALYSIS: A sample of 240 deceased with 30 years or more will be evaluated...

Fat-associated lymphoid clusters (FALC) are inducible structures that support rapid innate-like B-cell immune responses in the serous cavities. Little is known about the physiological cues that activate FALCs in the pleural cavity and more generally the mechanisms controlling B-cell activation in FALCs. Here we show, using separate models of pleural nematode infection with Litomosoides sigmodontis and Altenaria alternata induced acute lung inflammation, that inflammation of the pleural cavity rapidly activates mediastinal and pericardial FALCs...

OBJECTIVE: Major depressive disorder (MDD) is associated with an estimated fourfold risk for premature death, largely attributed to cardiovascular disorders. Pericardial adipose tissue (PAT), a fat compartment surrounding the heart, has been implicated in the development of coronary artery disease. An unanswered question is whether people with chronic MDD are more likely to have elevated PAT volumes versus acute MDD and controls (CTRL). METHODS: The study group consists of sixteen patients with chronic MDD, thirty-four patients with acute MDD, and twenty-five CTRL...

Adipose tissue, a major endocrine organ, consists of brown and white adipocytes. Brown fatmay play a beneficialrole in cardiometabolic disordersBrown adipose tissue can also improve glucose and lipid metabolism. In contrast, the expansion of white adipose tissue has been related to obesity, type 2 diabetes mellitus and cardiovascular disease (CVD). Both the quantity and the quality of the white adipose tissue as well as its distribution may affect CVD risk. In this context, the link between adiposity and CVD risk is greater for visceral than subcutaneous fat...
