AIMS Catheter ablation is an effective treatment for atrial fibrillation (AF). The outcome of AF ablation in septuagenarians is not clear. Our aim was to evaluate success rate, outcome, and complication rate of AF ablation in septuagenarians. METHODS AND RESULTS We collected data from 174 consecutive patients over 75 years of age who underwent AF ablation(More)
INTRODUCTION Around 30% of patients do not respond to cardiac resynchronization therapy (CRT). Nonischemic cardiomyopathy has been identified as an independent predictor of response to CRT, probably due to the absence of compact scar. METHODS AND RESULTS The relationship between cardiac scar, ischemia, and hibernation (both at the left-ventricular pacing(More)
BACKGROUND The benefit of biventricular pacing (BiV) may be substantially affected by optimal lead placement. AIM To evaluate the importance of right ventricular (RV) lead positioning on clinical outcome of BiV. METHODS AND RESULTS A total of 99 patients with symptomatic heart failure and implantation of BiV system were included. Position of the(More)
AIMS We assessed the relationship between cardiac resynchronization therapy (CRT)-induced reverse remodelling and mortality during a long-term follow-up in a prospective observational study. METHODS AND RESULTS We analyzed data from a prospective registry including 398 consecutive patients who underwent CRT between September 1998 and September 2007. Left(More)
BACKGROUND Despite the recent advances in cardiac mapping, ablation of scar-related ventricular tachycardia (VT) still remains a clinical challenge. A detailed electroanatomical map is a prerequisite for accurate localization and ablation of the VT substrate. OBJECTIVE The purpose of this study was to evaluate the feasibility and accuracy of integrating(More)
Restoration of the atrioventricular (AVD) and interventricular (VVD) delays increases the hemodynamic benefit conferred by biventricular (BiV) stimulation. This study compared the effects of different AVD and VVD on cardiac output (CO) during three stimulation modes: BiV-LV = left ventricle (LV) preceding right ventricle (RV) by 4 ms; BiV-RV = RV preceding(More)
INTRODUCTION Alcohol septal ablation and surgical myectomy represent accepted therapeutic options for treatment of symptomatic patients with hypertrophic obstructive cardiomyopathy. Long-term experience with radiofrequency ablation of arrhythmogenic substrates raised a question if this technique might be effective for left ventricular outflow tract (LVOT)(More)
The goal of this study was to analyze total procedural and fluoroscopic time during initial experience with implantation of LV lead in a single center, and to assess the performance of electrophysiologically-guided approach for cannulation of the coronary sinus (CS) in a subsequent period. Over an initial period of 29 months, a total of 46 attempts to(More)
BACKGROUND Decrease in neurohormonal activation during pharmacotherapy for chronic heart failure (CHF) is associated with haemodynamic and clinical improvement. We tested the hypothesis that changes in neurohormonal activation after initiation of cardiac resynchronization therapy (CRT) predict its long-term clinical effect. METHODS The study group(More)
Acute hemodynamic studies suggest that resynchronization therapy using single-site left ventricular pacing (LVP) is equivalent to biventricular pacing (BIVP). The aim of this study was to assess the performance of LVP versus BIVP during exercise by means of stress echocardiography. A total of 28 patients (25 men and 3 women, mean age 60.9 +/- 8 years) with(More)
