  • Riata ICD Lead Failures

    The Riata and Riata ST ICD leads manufactured by St. Jude Medical have recently come under increased scrutiny because of the observation that the conductor cables could extrude from the outer insulation.
  • Cardiac Device-Related Infective Endocarditis

    This study reports data from the International Collaboration on Endocarditis-Prospective Cohort Study (ICE-PCS) on the clinical characteristics of infective endocarditis related to pacemakers and ICDs.
  • PCI in Addition to Medical Therapy for Stable CAD — The Debate Continues

    Medical therapy is the mainstay of treatment for coronary artery disease (CAD), resulting in improved clinical outcomes. Revascularization with percutaneous coronary intervention (PCI), in addition to medical therapy, improves symptoms in patients with stable CAD.
  • New Cardiomyopathy

    Concentric left ventricular hypertrophy (CLVH) is occasionally unexplained. Thus, these investigators from Beijing, China, sought evidence for Danon disease, a glycogen storage disease, in patients being evaluated for cLVH who underwent endomyocardial biopsy.
  • Risk of Sudden Cardiac Death with Azithromycin

    In this paper, the authors performed a pharmacoepidemiologic study on the relationship between azithromycin, a frequently used broad-spectrum macrolide antibiotic, and cardiovascular death. The authors analyzed data from the Tennessee Medicaid program. This database provides information on medical care encounters and dates and causes of death and is linked to death certificates and hospital discharge data.
  • New Cardiomyopathy

    These investigators from Australia present a case of isolated left ventricular (LV) apical hypoplasia with fatty infiltration confirmed by CT and MRI. The left anterior descending artery was small and truncated early on angiography. Echocardiography showed a large banana-shaped right ventricle (RV) that wrapped around the apex of the hypocontractile truncated LV. Also there was apical papillary muscle insertion.

  • New Insights into Atrial Fibrillation Ablation

    This interesting study examined a new technique for exploring the mechanism(s) for atrial fibrillation (AF). Patients scheduled for catheter ablation of paroxysmal or persistent AF were recruited for the study. Antiarrhythmic drugs were stopped before the study was performed.
  • Pharmacology Watch

    Azithromycin and cardiac risk; warfarin and heart failure; aspirin and VTE; effectiveness of long-acting contraceptives; and FDA actions.
  • Management of Atrial Fibrillation in Chronic Kidney Disease Patients

    Patients with chronic kidney disease or who have had renal replacement therapy have often been excluded from trials of anticoagulation in atrial fibrillation (AF). In this study, the authors analyzed data from hospitalized patients with nonvalvular AF in Denmark from 1997 through 2008. Patients with chronic kidney disease with and without renal replacement therapy were identified from a national registry.
