Impact of Structural Heart Disease on the Acute Complication Rate in Atrial Fibrillation Ablation: Results from the German Ablation Registry
Acute Complication Rate in AF Ablation Introduction Catheter ablation (CA) has emerged as a widespread therapeutic option in the treatment of atrial fibrillation (AF). Currently, no safety data with regard to the impact of the underlying structural heart diseases (SHD) are available. We sought to assess the risk for acute and long-term complications during CA of AF in relation to underlying SHD. Methods and Results We included 6,211 patients in a prospective registry undergoing CA of AF in 41 nationwide centers. All patients were divided into 4 groups according to the underlying heart disease: No SHD (69.4%), hypertensive heart disease (HHD) (12.0%), coronary artery disease (CAD) (15.1%), a…
Complication Rates of Catheter Ablation of Atrial Fibrillation in Patients Aged ≥75 Years versus <75 Years-Results from the German Ablation Registry
Age-Related Complication Rates in AF AblationIntroduction Despite a rising demand for catheter ablation (CA) of atrial fibrillation (AF) in an elderly population, complication and success rates are not fully elucidated. We sought to compare complication rates of CA of AF in patients ≥75 versus <75 years of age. Methods and Results Patients with symptomatic, drug-refractory AF were prospectively enrolled from January 2007 to 2010 in this multicenter study. A total of 4,449 patients, group 1 ≥75 years and group 2 <75 years (n = 227, age 77.3 ± 2.2 vs. 59.7 ± 9.8 years, 52.0% vs. n = 4,222, 68.9% male, CHA2DS2-VASc-Score 3.7 ± 1.0 vs. 1.7 ± 1.2; P < 0.001, respectively), with paroxysmal AF (59…
