BACKGROUND Axillary vein puncture has been demonstrated to be an effective method for pacemaker and defibrillator leads implantation, without the complications encountered with the standard intrathoracic approach. OBJECTIVE Different techniques have been adopted for the cannulation of the axillary vein. We report our experience using the outer edge of the(More)
BACKGROUND Implantable cardioverter defibrillators (ICDs) and cardiac resynchronization therapy (CRT) reduce mortality in patients with heart failure (HF) and left ventricular dysfunction. However, their efficacy in patients with chronic kidney disease (CKD) is controversial. OBJECTIVE We examined the association between renal dysfunction and clinical(More)
Low/medium-bleeding-risk populations undergoing percutaneous coronary intervention (PCI) show significantly less bleeding with bivalirudin (BIV) than with unfractionated heparin (UFH), but this has not been established for high-risk patients. We performed a randomized double-blind prospective trial comparing efficacy and safety of BIV versus UFH combined(More)
Lead insulation material and implant route have a major impact on lead reliability and durability. We compare the incidence of lead insulation failure resulting from both the venous approach and insulation type. Two hundred ninety consecutive leads were followed for a mean period of 57 +/- 30 months; leads with < 1 year follow-up were excluded. There were(More)
The aim of this retrospective study was to determine the incidence of symptomatic AF of patients who had undergone coronary artery bypass grafting (CABG) during long-term follow-up. The study population included 305 post-CABG patients who were regularly followed in the outpatient clinic. Paroxysmal AF (PAF) was defined as an episode of symptomatic AF when(More)
BACKGROUND Torsade de pointes is rarely associated with chronic amiodarone treatment, despite the effect of amiodarone on QT interval prolongation. OBJECTIVE To identify risk factors and associated conditions that may cause TdP in patients on chronic amiodarone treatment. METHODS We reviewed the data of six consecutive patients on chronic amiodarone(More)
Torsades de pointes (TdP) has not been previously reported with loratadine. A 73-year old woman on chronic treatment with amiodarone for atrial fibrillation received loratadine and presented with syncope and multiple episodes of TdP. We suggest that QT interval should be monitored whenever loratadine is co-administered with drugs that may potentially(More)
BACKGROUND Current clinical guidelines restrict catheterization laboratory activity without on-site surgical backup. Recent improvements in technical equipment and pharmacologic adjunctive therapy increase the safety margins of diagnostic and therapeutic cardiac catheterization. OBJECTIVE To analyze the reasons for urgent cardiac surgery and mortality in(More)
BACKGROUND During lead implantation, venous access is generally achieved by puncturing the subclavian or axillary vein. Sometimes, although rarely, after lead positioning, the lead must be changed because of its inadequate mechanical stability or poor pacing parameters. This report concerns a technique of lead exchange that avoids an additional vein(More)
