BACKGROUND The aim of the study was to compare in our center the effect of different ablation techniques on intermediate term freedom from atrial fibrillation (AF) or atrial tachycardia (AT) in patients affected by refractory AF. METHODS AND RESULTS We retrospectively selected 94 patients who underwent AF ablation in our electrophysiological laboratory… (More)
Atrial fibrillation (AF) is a frequent chronic dysrythmia with an incidence that increases with age (>40). Because of its medical and socio-economic impacts it is expected to become an increasing burden on most health care systems. AF is a multi-factorial disease for which the identification of subtypes is warranted. Novel approaches based on the broad… (More)
AIMS To evaluate the effects of pulmonary vein isolation (PVI) in terms of feasibility, safety and success rate on a midterm follow-up period in septuagenarians undergoing ablation with the Arctic Front Cryoballoon for atrial fibrillation (AF). METHODS AND RESULTS We prospectively enrolled 21 patients aged 70 years or older (14 male; age 73 ± 2.5 years)… (More)
A 65-year-old man was admitted to our centre because of recurrent drug-resistant episodes of paroxysmal atrial fibrilla-tion, for pulmonary vein radiofrequency catheter ablation. Double transseptal (TS) puncture was performed under real-time three-dimensional transoesophageal echocardiography (RT 3D TEE) guidance. We started by placing a quadripolar… (More)
BACKGROUND Although the assessment of diastolic dysfunction (DD) is an integral part of routine cardiologic examinations, little is known about associated electrocardiographic (ECG) changes. Our aim was to investigate a potential role of ECG indices for the recognition of patients with DD. METHODS AND RESULTS ECG parameters correlating with… (More)
BACKGROUND Recently, we and others reported that early repolarization (J wave) is associated with idiopathic ventricular fibrillation. However, its clinical and genetic characteristics are unclear. METHODS AND RESULTS This study included 50 patients (44 men; age, 45 ± 17 years) with idiopathic ventricular fibrillation associated with early repolarization,… (More)
We present an unusual transient pro-arrhythmic effect of ajmaline in a patient with resuscitated cardiac arrest and a left ventricular apical aneurysm. We discuss the clinical presentation and the possible physio-pathological explanation for this new pro-arrhythmic effect linked to administration of intravenous ajmaline.
