AIMS To evaluate diagnostic accuracy of contrast echocardiography (CE) as compared with CT, for the screening of pulmonary arteriovenous malformations (PAVMs) in hereditary haemorrhagic telangiectasia (HHT); to evaluate the clinical significance of semi-quantitative analysis of a shunt on CE. METHODS AND RESULTS A blinded prospective study was conducted(More)
BACKGROUND Radiofrequency catheter ablation is a well-established approach to treating several types of cardiac arrhythmias. The aim of our study was to provide data on the diffusion of catheter ablation procedures in clinical practice through a meta-analysis of National Registries of electrophysiological procedures performed over a 5-year period, from 2000(More)
We describe a case of out-of-hospital cardiac arrest due to ventricular fibrillation in a patient with transient left ventricular apical ballooning syndrome. Our report confirms that left ventricular apical ballooning may have the same complications of myocardial infarction, adding the early ventricular fibrillation to the previous findings of left(More)
We describe a 74-year-old female patient with unstable angina. The coronary angiogram showed the presence of a single coronary artery arising from the right sinus of Valsalva, which is a very uncommon congenital anomaly, with subocclusive atherosclerotic plaques at the proximal and distal right coronary artery. The stenoses were treated through percutaneous(More)
We describe the case of a 30-year-old pregnant woman who underwent pacemaker implantation for recurrent syncope caused by sinus arrest. In order to minimize radiation exposure, which may potentially have teratogenic effects, we decided to perform pacemaker implantation by means of a hybrid technique involving the evaluation of electrophysiologic signals and(More)
Atrial fibrillation (AF) is one of the most frequent findings in the general population, with an incidence of about 0.1% per year and a mean prevalence of 0.95%. However, prevalence values are known to vary with age, being very low (0.1-0.2%) in subjects less than 55 years old, the age group comprising the greatest number of individuals who practice sport(More)
Atrial fibrillation (AF) is the most frequent cause of prolonged palpitations in young competitive athletes, even including those performing elite sport activity. This arrhythmia may occasionally affect impair athletes' ability to compete thus leading to non-eligibility at prequalification screening. Competitive sport has a significant impact on the(More)
Radiofrequency (RF) catheter ablation has not been widely undertaken in elderly patients. The aim of our study was to compare the success rate of radiofrequency ablation and the incidence of severe procedural complications in young-adult and elderly patients. We enrolled all patients undergoing radiofrequency catheter ablation procedures for(More)
BACKGROUND Syncope in patients with bifascicular block (BFB) is a common event whose causes might be difficult to assess. METHODS AND RESULTS Prevention of syncope through permanent cardiac pacing in patients with bifascicular block (PRESS) is a multicenter, prospective, randomized, single-blinded study designed to demonstrate a reduction in symptomatic(More)
This report describes a 64 year-old female patient admitted to our department for recurrent and symptomatic episodes of atrial fibrillation. Antiarrhythmic therapy with sotalol at 240 mg/day was started, and after 48 h the patient experienced several episodes of sustained torsade de pointes, dramatic marked QT interval prolongation and negative T wave, in(More)
