Yazd Province of Iran ICD Registry for the Years 2014–2016

Abstract

This study aimed to investigate the trends in the care of patients undergoing implantable cardioverter-defibrillator (ICD) implantation in our region and to analyze whether the quality of care is the same as the other centers or not? Adult patients with an indication for ICD implants were enrolled in our registry and followed over a 19-43-month period. The ICD implantation rate was 100/million per year. The mean age of patients treated with ICD was 62.36 (±12.93) years old and the majority of patients were men (77.6%). Most patients had ischemic heart failure (65.2%). Nearly half of the patients had NYHA class III (53.8%) and the mean of ejection fraction was 26.7 (±9.8%). ICDs were frequently implanted for primary prevention (71.9%). Single chamber ICDs (ICD-VR) were chosen in 25.2%, dual-chamber ICDs in 37.1% (ICD-DR) and biventricular ICDs (CRT-D) in 37.6%, respectively. Complications related to ICD implantation occurred in about 7.49% of all procedures. During follow-up period death occurred in 14.8% of our patients. Also, 13.3% of patients received ICD shock which was appropriate in 71% of patients. In comparison between our registry and NCDR registry, baseline patient characteristics and ICD type were almost the same, but the complication rate was higher. There is still a need to perform a large multicenter registry in our community to improve our knowledge in this Era.
