Abstract

Introduction and objectives: We describe the results for Spain of the Second European Cardiac Resynchronization Therapy Survey (CRT-Survey II) and compare them with those of the other participating countries. Methods: We included patients undergoing CRT device implantation between October 2015 and December 2016 in 36 participating Spanish centers. We registered the patients’ baseline characteristics, implant procedure data, and short-term follow-up information until hospital discharge. Results: Implant success was achieved in 95.9%. The median [interquartile range] annual implantation rate by center was significantly lower in Spain than in the other participating countries: 30 implants/y [21-50] vs 55 implants/y [33-100]; P = .00003. In Spanish centers, there was a lower proportion of patients (cid:3) 75 years (27.9% vs 32.4%; P = .0071), a higher proportion in NYHA class II (46.9% vs 36.9%, P < .00001), and a higher percentage with electrocardiographic criteria of left bundle branch block (82.9% vs 74.6%; P < .00001). The mean length of hospital stay was significantly lower in Spanish centers (5.8 (cid:4) 8.5 days vs 6.4 (cid:4) 11.6; P < .00001). Spanish patients were more likely to receive a quadripolar LV lead (74% vs 56%, P < .00001) and to be followed up by remote monitoring (55.8% vs 27.7%; P < .00001). Conclusions: The CRT-Survey II shows that, compared with other participating countries, fewer patients in Spain aged (cid:3) 75 years received a CRT device, while more patients were in New York Heart Association functional class II and had left bundle branch block.
