About 30% of patients treated with cardiac resynchronization therapy (CRT) do not respond to treatment. The aim of this study was to identify clinical predictors of lack of improvement in patients receiving CRT. From 197 consecutive patients scheduled to receive CRT, 143 fulfilled the inclusion criteria. Mean age was 68 +/- 7 years and 79% were men. Heart(More)
Numerous clinical studies have demonstrated the therapeutic benefit of trastuzumab in women with breast cancer. However, a small but not insignificant proportion of patients have experienced trastuzumab-associated cardiotoxicity during these trials. This phenomenon is generally characterized by an asymptomatic reduction in left ventricular ejection fraction(More)
UNLABELLED Fabry cardiomyopathy (FC) is characterized by left ventricular hypertrophy (LVH). The aim of this study is to determine whether early changes revealed by tissue Doppler imaging (TDI) are useful for detecting preclinical cardiac abnormalities in patients with this X-linked genetic disorder. If so, this tool could help in deciding whether to begin(More)
OBJECTIVES Apical ballooning shares features with acute coronary syndromes. Recently, atypical forms have been reported without apical involvement. Usually, the prognostic reports have compared them with ST-segment elevation infarction. Left ventricular transient dyskinesias (LVTD), however, frequently occur without ST-segment elevation and when present,(More)
OBJECTIVES The aim of this study was to examine the feasibility of transthoracic two-dimensional (2D)-echocardiography in defining the cavo-tricuspid isthmus (CTI) anatomy and its value concerning the ease of catheter ablation of isthmic atrial flutter (AF). METHODS CTI analysis was accomplished in 39 cases: 16 necropsy specimens and 23 patients. Sixteen(More)
AIM To study recent experience and safety of ergonovine stress echocardiography in our centre. METHODS In this study we collected the clinical variables of patients referred since 2002 for ergonovine stress echocardiography, in addition to indications, the results of this test, complications, blood pressure and heart rate values during the test and the(More)
INTRODUCTION The incidence of type 2 diabetes mellitus (T2DM) is increasing worldwide. When diagnosed, many patients already have organ damage or advance subclinical atherosclerosis. An early diagnosis could allow the implementation of lifestyle changes and treatment options aimed at delaying the progression of the disease and to avoid cardiovascular(More)
Paraganglioma, also referred to as pheochromocytoma when functionally active, is a rare tumor thought to arise from the neuroectodermally derived paraganglionic cells that are dispersed widely along the autonomic ganglia. Mediastinal localization is very rare and the clinical presentation is variable. In most cases, hypertension due to catecholamine excess(More)
