Dual-chamber defibrillators reduce clinically significant adverse events compared with single-chamber devices: results from the DATAS (Dual chamber and Atrial Tachyarrhythmias Adverse events Study) trial
April 28th, 2008 by 
admin This irregular effort evaluated clinically momentous inauspicious events (CSAEs), in patients established with dual-chamber (DC) vs. single-chamber (SC) implantable cardioverter defibrillator (ICD). DC-ICD had atrial tachyarrhythmia (AT) therapy capabilities. Strict planning recommendations were reinforced.
Patients with customary SC-ICD communication were irregular to DC-ICD, SC-ICD, or a DC-ICD programmed as an SC-ICD (SC-simulated) and followed for 16 months. Patients in the DC and SC-simulated groups decussate over after 8 months. The direct end was a flower of CSAE: all-cause mortality; intrusive intervention; hospitalisation (>24 h) for cardiovascular causes; incongruous shocks (two or more episodes); and uninterrupted characteristic AT long >48 h. The outcome uncertain was a pre-specified reason that rectified for clinical rigor and follow-up duration. Three cardinal and thirty-four patients were analysed (DC-ICD, n = 112; SC-ICD, n = 111; SC-simulated, n = 111). The stingy mitt ventricular banishment cypher was 0.36 ± 0.13, 69% were in useful collection ≥II. CSAE occurred in 65 DC-ICD, 82 SC-ICD, and 84 SC-simulated patients. The outcome uncertain was 33% modify in the DC-ICD assemble (OR 0.31; 95% CI 0.14–0.67; P = 0.0028). Mortality was 4% in DC, 9% in SC, and 10% in SC-simulated.
In patients with a accepted SC-ICD indication, DC-ICD was related with inferior CSAE when compared with SC-ICD.
