INTRODUCTION Venous occlusion is a relatively common complication of endocardial lead implantation. It may cause a critical problem when implantation of a new lead is needed. Traditional methods result in leaving abandoned leads. The optimal approach seems to be the extraction of the damaged or abandoned lead, regaining venous access and implantation of a(More)
BACKGROUND Rapid conversion of atrial fibrillation (AF) to sinus rhythm may be achieved by the administration of class IA, IC and III antiarrhythmic drugs or vernakalant hydrochloride. However, that treatment may be related to potential pro-arrhythmia, lack of efficacy or the exceptionally high cost of a compound used. Antazoline is a first generation(More)
INTRODUCTION Over the last 10 years, there has been an increasing number of patients with pacemaker (PM) and cardioverter-defibrillator (ICD). This study is a retrospective analysis of indications for endocardial pacemaker and ICD lead extractions between 2003 and 2009 based on the experience of three Polish Referral Lead Extraction Centers. MATERIAL AND(More)
PURPOSE Radiofrequency ablation (RFA) is considered the treatment of choice in cases of atrioventricular nodal reciprocating tachycardia (AVNRT) and atrioventricular reciprocating tachycardia (AVRT). Published studies suggest a considerable time gap between the onset of the arrhythmia, correct diagnosis, and RFA which may reach 10-15 years. The cost of(More)
The authors present the case of a 62-year-old male patient with an implantable cardioverter-defibrillator and end-stage heart failure supported with an intra-aortic balloon pump. Implantation of a triple-site cardiac resynchronization system and complex heart failure treatment brought a significant improvement, return to home activity and 17-month survival.(More)
BACKGROUND Previously presented new electrocardiography (ECG) algorithm for localization of arrhythmogenic focus (AFo) in right ventricular outflow tract (RVOT) was based on spontaneous arrhythmia QRS morphology analysis. The aim of this study was to estimate the clinical value of our RVOT algorithm in a prospective study. METHODS AND RESULTS Algorithm(More)
BACKGROUND The increasing number of patients with cardiac implantable electronic devices (CIEDs) causes a rise in the absolute percentage of individuals qualifying for a transvenous lead extraction (TLE) due to infectious, vascular or lead failure related indications. As the survival time prolongs, TLE procedures more and more often concern the electrodes(More)
Transvenous lead extraction can be a method to regain venous access. We present the case of a man, aged 67, with indications to upgrade an ICD to a resynchronization therapy device. Since innominate vein occlusion was diagnosed and extraction of an abandoned ventricular pacing lead did not provide lumen regain, a functional atrial lead was extracted with(More)
BACKGROUND AND AIM Effectiveness of implantable cardioverter-defibrillators (ICD) in patients with reduced left ventricular ejection fraction after myocardial infarction has been documented in large randomised trials. We analysed the predictive value of clinical factors at the time of implantation for adequate ICD interventions and mortality risk. METHODS(More)
