BACKGROUND Patients with idiopathic dilated cardiomyopathy (DCM) and impaired left ventricular ejection fraction have an increased risk of dying suddenly. METHODS AND RESULTS Patients with recent onset of DCM (< or =9 months) and an ejection fraction < or =30% were randomly assigned to the implantation of an implantable cardioverter-defibrillator (ICD) or(More)
INTRODUCTION Bidirectional conduction block at the subeustachian isthmus predicts long-term efficacy of atrial flutter ablation. Limited data are available on the incidence and outcome of minor conduction changes such as unidirectional or incomplete block. This prospective study sought to systematically assess discrete acute and long-term alterations of(More)
BACKGROUND The coronary venous system is increasingly used for left ventricular or biventricular pacing in patients with severe heart failure. The present study investigated the structure of the coronary veins in patients presenting with structural heart disease and malignant ventricular tachyarrhythmias. The availability of veins for possible lead(More)
Einteilung der Tachykardien: stabil – instabil supraventrikulär – ventrikulär Herzrhythmusstörungen sind häufig Anlaß für den betroffenen Patienten bzw. Angehörigen, den Rettungsdienst zu rufen. Der korrekten Diagnose und Akuttherapie am Notfallort wegen bradykarderund vorwiegend tachykarder Herzrhythmusstörungen kommt daher eine besondere Bedeutung zu. Es(More)
Appropriate and inappropriate therapies of implantable cardioverter defibrillators have a major impact on morbidity and quality of life in ICD recipients, but have not been systematically studied in children and young adults during long-term follow-up. ICD implantation was performed in 20 patients at the mean age of 16 +/- 6 years, 11 of which had prior(More)
AIMS First-line ablation prior to antiarrhythmic drug (AAD) therapy is an option for symptomatic paroxysmal atrial fibrillation (PAF); however, the optimal ablation technique, radiofrequency (RF), or cryoballoon (CB) has to be determined. METHODS AND RESULTS The FREEZE Cohort Study compares RF and CB ablation. Treatment-naïve patients were documented in(More)
OBJECTIVES Five drug classes have been shown to improve the prognosis of acute myocardial infarction in clinical trials: aspirin, beta-blockers, statins, renin angiotensin system (RAS) blockers and thienopyridines. We aimed to assess whether the benefits of combining these drugs (termed optimal medical therapy, OMT), will result in a reduction of mortality(More)
BACKGROUND Defibrillation thresholds (DFT) with standard implantable cardioverter-defibrillator leads in the right ventricle (RV) may be determined by weak shock field intensity in the myocardium of the left ventricle (LV). Adding a shocking electrode in a coronary vein on the middle of the LV free wall, thereby establishing biventricular defibrillation,(More)
BACKGROUND The purpose of the present study was to determine the role of a novel, noncontact mapping system for assessing a variety of atrial reentrant tachycardias (ART) in patients after the surgical correction of congenital heart disease. METHODS AND RESULTS In 14 patients, an electrophysiological study using the Ensite 3000 system was performed to(More)
