BACKGROUND The purpose of this multicenter study was to determine the reliability of visual assessments of segmental wall motion (WM) abnormalities and global left ventricular function among highly experienced echocardiographers using contemporary echocardiographic technology in patients with a variety of cardiac conditions. METHODS The reliability of(More)
BACKGROUND Cardiac tumours are very uncommon and are the topic of little investigation. Imaging features offer reliable diagnostic evidence for cardiac tumours, but diagnostic confusion may arise when tumours with similar features are present. METHODS Between January 2003 and July 2008, 34 patients were operated on for cardiac tumours in this institute.(More)
OBJECTIVES The aim of this study was to evaluate the significance of increased left atrial (LA) volume determined within the first 48 h of admission as a long-term predictor of outcome in patients with acute myocardial infarction (MI). BACKGROUND The LA volume reflects left ventricular (LV) diastolic properties. Whereas other LV Doppler diastolic(More)
BACKGROUND Left atrial volume (LAV) is an important marker of heart failure (HF) severity. We hypothesized that LAV independently correlates with clinical outcomes in patients who receive cardiac resynchronization therapy with a defibrillator (CRT-D) and can be used for improved risk assessment in this population. METHODS AND RESULTS The benefit of CRT-D(More)
BACKGROUND Heart failure with preserved ejection fraction (HFpEF) comprises a large portion of heart failure patients and portends poor prognosis with similar outcome to heart failure with reduced ejection fraction (HFrEF). Thus far, no medical therapy has been shown to improve clinical outcome in this common condition. TRIAL DESIGN The study is a(More)
BACKGROUND Patients with complex congenital heart disease (CHD) have a high incidence of extracardiac vascular and non-vascular malformations. Those additional abnormalities may have an impact on the precise planning of surgical or non-surgical treatment. OBJECTIVES To assess the role of electrocardiography-gated CT-angiography (ECG-CTA) in the routine(More)
We evaluated the potential advantage of real-time 3-dimensional echocardiography on the assessment of mitral valve morphology and function in patients with isolated cleft mitral valve. Five patients, aged 33 +/- 9 years, with isolated cleft mitral valve and no associated cardiac anomalies, were studied. Real-time 3-dimensional echocardiography demonstrated(More)
OBJECTIVES The aim of this study was to evaluate whether certain post-Maze left atrial (LA) contractile profiles may pose a risk for ischemic stroke. BACKGROUND The mechanical contraction of the left atrium may be modified after the Maze procedure. Whether this imposes a risk for stroke, even in the presence of sinus rhythm and after removal of the LA(More)
Intravenous leiomyomatosis is a rare, benign neoplasm of the uterine, affecting adult women. We report two cases in whom intravenous leiomyomatosis extended through the inferior vena cava into the right heart chambers and the pulmonary artery. Both patients underwent staged operation with excision of the cardiac and primary tumour. The differential(More)
