Studies on CRT-D Longevity
Battery Longevity in Cardiac Resynchronization Therapy Defibrillators was an independent, retrospective, and first-of-its-kind study – inclusive of devices with contemporary battery technology – that showed there are discrepancies in battery longevity of CRT-D devices.
The 4-year survival rate3 of device battery was 67 % for Medtronic devices compared to 94 % for Boston Scientific devices and 92 % for St. Jude Medical devices.3
BOSTON SCIENTIFIC = 173 PATIENTS
MEDTRONIC = 416 PATIENTS
ST. JUDE = 57 PATIENTS
Device Longevity in Cardiac Resynchronization Therapy Implantable Cardioverter Defibrillators Differs Between Manufacturers: Data from the Danish ICD Registry was the second independent, retrospective study inclusive of devices with contemporary battery technology that agreed with the results of Dr. Saba’s study – Boston Scientific CRT-Ds lasted significantly longer than Medtronic CRT-Ds.
NEW DATA FROM HRS 2014:
The 4-year survival rate4 of device battery was 81.1 % for Medtronic devices compared to 95.7 % for Boston Scientific devices and 93.6 % for St. Jude Medical devices.4
BOSTON SCIENTIFIC = 136 PATIENTS
MEDTRONIC = 651 PATIENTS
ST. JUDE = 1,587 PATIENTS
BIOTRONIK = 369 PATIENTS
Contemporary Cardiac Resynchronization Implantable Cardioverter Defibrillator Battery Longevity in a Community Hospital Heart Failure Cohort was the third independent, retrospective study inclusive of devices with contemporary battery technology that also agreed with the results of both Dr. Saba and Dr. Johansen’s studies – Boston Scientific CRT-Ds lasted significantly longer than Medtronic CRT-Ds.
NEW DATA FROM HFSA 2014:
The 4-year survival rate5 of device battery was 50 % for Medtronic devices compared to 98.1 % for Boston Scientific devices and 90 % for St. Jude Medical devices.5
BOSTON SCIENTIFIC = 53 PATIENTS
MEDTRONIC = 28 PATIENTS
ST. JUDE = 10 PATIENTS

NEW DATA FROM HFSA 2014:
Ampere Hour as a Predictor of CRT ICD Pulse Generator Longevity: A Multi-Center Study showed Boston Scientific CRT-Ds are lasting significantly longer than both Medtronic and St. Jude CRT-Ds.
This study also concluded that battery capacity (aka ampere hours) is a predictor of longevity.
BOSTON SCIENTIFIC = 273 PATIENTS
MEDTRONIC = 587 PATIENTS
ST. JUDE = 153 PATIENTS
Boston Scientific believes access to product performance information is essential to medical professionals and to patients and their families. In the Product Performance Report, you will find:
The LILAC study demonstrated that single placement of the novel Boston Scientific quadripolar, spiral leads allowed acceptable pacing performance with low pacing thresholds (PT) and phrenic nerve stimulation (PNS) avoidance.7
