Yazd Province of Iran ICD Registry for the Years 2014-2016.

Objective: 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?

Methods: Adult patients with an indication for ICD implants were enrolled in our registry and followed over a 19-43-month period.

Results: 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.

Conclusions: 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.
