Costlier Heart Device May Not Be Worth It, Study Suggests

Dual-chamber implanted defibrillators had more complications than single-chamber models

HealthDay SHARE

Another question they weren't able to address in the study was cost. Single-chamber devices are initially less expensive than dual-chamber models.

A study published in September 2005 in the Journal of the American College of Cardiology said it costs roughly $34,000 for a single-chamber device and about $38,000 for a dual-chamber model.

But that study also found that the cost savings of single-chamber devices can be wiped out if patients need to upgrade to the dual-chamber model because their condition gets worse, a situation that occurs in about 5 to 6 percent of patients in clinical trials.
