Pacemaker lead infection is a rare condition, most often occurring when intervention is needed after pacemaker implantation. Diagnosis is by blood cultures and confirmation by transoesophageal echocardiography; transthoracic echocardiography is often inadequate. A literature review indicated the microorganism most responsible for late lead infection is Staphylococcus epidermidis (which can grow...
AIMS To assess the agreement of left ventricular ejection fraction (LVEF) determinations from unenhanced echocardiography, contrast-enhanced echocardiography, magnetic resonance imaging (MRI), and cineventriculography as well as the inter-observer agreement for each method. METHODS AND RESULTS In 120 patients, with evenly distributed EF-groups (> 55, 35-55, < 35%), cineventriculography, unenh...
The Working Group on Echocardiography (WGE) of the Romanian Society of Cardiology was formally founded in 1991. Activities related to echocardiography took place occasionally even before, as early as 1977, when a first symposium on echocardiography was held, while in 1982 a first course on cardiac ultrasound was organized in Bucharest.
