The National ICD Registry Report released a new version that expands on the 2009 Annual Report to include data on leads and pediatric implants to reflect recent advancements in healthcare.

Through collaboration with the FDA, the registry now incorporates lead data fields to track when leads are implanted, revised, removed or abandoned. More than 560,000 leads were entered into Version 2.1. In addition, for the first time, the Pediatric and Congenital Electrophysiology Society (PACES) worked with the registry to account for pediatric implants and congenital heart disease diagnosis. Registry data now includes over 300 pediatric implants.

Currently, the registry accrues ICD implants at the rate of more than 12,500 per month. In the seven quarters of data collection, 263,284 ICD procedures were performed in more than 250,000 patients. In total, at the end of 2011, the ICD registry accrued more than 850,000 ICD procedures.

From April 2010 through the end of 2011, the new version of the registry gathered new data on ICD utilization in the real world. Data highlights include:

• More than 260,000 procedures performed by more than 4,300 clinicians at 1,428 institutions;
• Primary prevention device implantation in 73.8 percent of patients;
• Secondary prevention indication in 22.5 percent;
• More than 560,000 leads entered into the database (57.6 percent new and 42.4 percent previously implanted); and
• More than half of the physicians recording implant procedures are EP Board Certified or completed an electrophysiology fellowship, accounting for 83 percent of all ICD implants.

Evaluation of the data since the previous ICD registry was published shows key changes in the landscape of ICD implantation. Compared to 2009 data:

• Total number of procedures included in the registry increased 6.4 percent, which is partially related to the inclusion of “lead only” procedures which accounted for 62 percent of the additional monthly procedures; and
• Less single and dual chamber ICDs and more cardiac resynchronization devices, which is primarily a result of an increase in replacement devices growing from 25 percent to almost 40 percent.
