While researchers and device makers have focused on improving the safety and efficacy of pacemakers, implantable cardioverter-defibrillators, and other cardiovascular implantable electronic devices, issues surrounding the lead wires that connect these tools to the myocardium have received less attention. But that dynamic is changing.
The Heart Rhythm Society has issued recommendations for policies and guidelines on lead performance and a consensus statement on transvenous lead extraction. The documents were released during the society's May scientific sessions in Boston.
NEED FOR GUIDANCE
Millions of patients are now living with cardiovascular implantable electronic devices. Studies have shown lead failure rates of between 1% and 9% at 2 years and up to 28% at 8 years. Simply replacing leads is not always an option; the procedure is associated with risk of complications, and mortality rates of more than 1% have been reported.
"There are times when leads can develop problems," said Richard L. Page, . . . [Full Text of this Article]
