OBJECTIVES: Although real-time ultrasound guidance during central venous catheter insertion has become a standard of care, postinsertion chest radiograph remains the gold standard to confirm central venous catheter tip position and rule out associated lung complications like pneumothorax. We hypothesize that a combination of transthoracic echocardiography and lung ultrasound is noninferior to chest radiograph when used to accurately assess central venous catheter positioning and screen for pneumothorax...

Chronic indwelling central venous catheters can result in formation of fibrin sheaths increasing risk of occlusion, thrombosis and infection. Endovascular infection of right-sided heart structures induced by such sheaths is very rare. A 48-year-old woman with end-stage renal disease initially treated for diabetic ketoacidosis developed persistent Staphylococcus epidermidis bacteraemia without an identifiable source. Although transthoracic echocardiography was unremarkable, transoesophageal echocardiography revealed a fibrin sheath and vegetations in superior vena cava-right atrium junction, which was the site of the tip of a central catheter that had been removed 2 months prior, consistent with fibrin sheath-associated endovascular infection...

BACKGROUND: Preoperative assessment of geriatric patients with a hip fracture may include transthoracic echocardiography (TTE), which increases resource utilization and cost and may delay surgery. The purpose of this study was to evaluate preoperative TTE utilization at a single institution in order to determine (1) how often TTE is ordered in accordance with clinical practice guidelines (CPGs), (2) how frequently TTE reveals cardiac disease that may alter medical or anesthesia management, and (3) whether following CPGs reduces unnecessary TTE utilization without potentially missing important disease...

Background: The fundoscopic examination of hypertensive patients, which is an established hypertension-related target organ damage (TOD), tends to be underutilized in clinical practice. We sought to investigate the relationship between retinal alterations and left atrium (LA) volumes by means of real-time, three-dimensional echocardiography (RT3DE), which is the most pivotal predictor of diastolic dysfunction. Methods: Our population consisted of 88 consecutive essential hypertensive patients (age 59...

Aims. The Assessment of left ventricular (LV) function remains a clinical challenge especially in patients with preserved LV ejection fraction (EF) and valvular heart diseases (VHD). Mechanical dispersion is supposed to be a strong predictor of events and, to be related to the extent of fibrosis. Regional cardiac work is a new validated and very promising approach to quantify LV-function. We investigated the differences in mechanical dispersions and global LV work (totW) and wasted work fraction (WWF) in normal subjects and in patients with severe primary mitral regurgitation (MR) and severe aortic stenosis (AS)...

Background.: The presence of patent foramen ovale (PFO) has been linked to many illness, including cryptogenic stroke, transient ischemic attack, migraine, platypnea-orthodeoxia syndrome and decompression sickness in scuba divers. Transesophageal echocardiography is the gold standard technique for the visualization of atrial septal anatomy, but it is a secondary level exam, not always available, with additional associated costs and not completely free from procedural risks. Standard transthoracic echocardiography (TTE) has a too low sensitivity for PFO screening...

BACKGROUND: Transesophageal echocardiography (TEE) is routinely performed before atrial fibrillation (AF) transcatheter ablation to exclude the presence of left atrial (LA) or LA appendage (LAA) thrombi. The aim of the study is to evaluate if easily accessible clinical parameters may relate to the presence of LA or LAA thrombi to identify patients who could potentially avoid TEE. METHODS AND RESULTS: Between January 2012 and September 2014, data from 1539 consecutive patients undergoing TEE, as a work-up before AF transcatheter ablation, in six large volume centers were collected...
