The implantable loop recorder is a useful diagnostic tool for patients with unexplained syncope. The capability to automatically detect and store arrhythmic events, implemented in the last generations of these devices, can further improve the diagnostic yield, but this feature can be compromised by inappropriate detection of false arrhythmias. We herein(More)
AIMS Vasovagal syncope (VVS) is a common disorder characterized by a drop in blood pressure accompanied with bradycardia; although it is generally considered a benign condition, some patients may be highly symptomatic despite general counselling and/or pharmacological therapy. Closed-loop stimulation (CLS), responding to myocardial contraction dynamics,(More)
Heart failure (HF) epidemic has increased need for accurate diastolic dysfunction (DD) quantitation. Cardiac MRI can elucidate left atrial (LA) phasic function, and accurately quantify its conduit contribution to left ventricular (LV) filling, but has limited availability. We hypothesized that the percentage of LV stroke volume due to atrial conduit volume(More)
AIMS Current guidelines recommend cardiac resynchronization therapy (CRT) in selected heart failure patients, but do not precisely clarify when a back-up implantable cardioverter defibrillator (ICD) should be associated (CRT-D). In this study we evaluate the occurrence of ventricular arrhythmias in a population of patients implanted with biventricular(More)
BACKGROUND Indication to implantable cardioverter defibrillator (ICD) for primary prevention of sudden death relies on left ventricular ejection fraction (LVEF). We measured the proportion of patients in whom indication to ICD persisted at the time of generator replacement (GR) and searched for predictors of appropriate therapies after GR. METHODS We(More)
PURPOSE OF REVIEW The left atrial cavity has recently been identified as a potential biomarker for cardiac and cerebrovascular accidents. This review examines the potential of left atrial size and function in predicting cardiovascular disease in the general population and outcomes in coronary artery disease (CAD) patients. RECENT FINDINGS The atrium is(More)
Coronary artery aneurysm (CAA) is an uncommon disease observed in only 0.15-4.9% of patients undergoing coronary angiography. CAA are defined as dilated coronary artery sections exceeding by 1.5 times the diameter of normal adjacent segments or of the patient's largest coronary vessel. Occasionally, CAA enlarge enough to be called giant CAA. We report the(More)
BACKGROUND As atrial stiffness (Kla) is an important determinant of cardiac pump function, better mechanical characterization of left atrial (LA) cavity would be clinically relevant. Pulmonary venous ablation is an option for atrial fibrillation (AF) treatment that offers a powerful context for improving our understanding of LA mechanical function. We(More)
Many clinically important differences exist between beta blockers. B1-selectivity is of clinical interest because at clinically used doses, b1- selective agents block cardiac b-receptors while having minor effects on bronchial and vascular b-receptors. Beta-adrenergic blocking agents significantly decrease the frequency and duration of angina pectoris,(More)
Coronary artery disease is the major cause of mortality and morbidity in the industrialized countries; in the United States of America and in Europe, it is responsible for one of every six deaths per year. In the setting of ischemic heart disease, angina pectoris and chest pain, in particular, are the major causes of emergency department accesses. Angina(More)
