In January 2005, the oversight responsibility of the Post-Approval Studies Program was transferred to the Division of Epidemiology (DEPI) of the Office of Surveillance and Biometrics (OSB)/Center for Devices and Radiological Health (CDRH).
The CDRH Post-Approval Studies Program encompasses design, tracking, oversight, and review responsibilities for studies mandated as a condition of approval of a premarket approval (PMA) application, protocol development product (PDP) application, or humanitarian device exemption (HDE) application. The program helps ensure that well-designed post-approval studies (PAS) are conducted effectively and efficiently and in the least burdensome manner.
CDRH has established an automated, internal tracking system that efficiently identifies the reporting status of active PAS studies ordered since January 1, 2005 based on study timelines incorporated in study protocols and agreed upon by the CDRH and applicants. This system represents CDRH's effort to ensure that all PAS commitments are fulfilled in a timely manner.
In addition, CDRH launched this publicly available webpage to keep all stakeholders informed of the progress of each PAS. The webpage displays general information regarding each PAS, as well as the overall study status (based on protocol-driven timelines and the adequacy of the data) and the applicant's reporting status for each submission due.
This study is designed to characterize the chronic performance of the St. Jude Medical QuickFlex®
ì Model 1258T LV Lead.
Study Population Description
Study Population: Patients with an approved indication, as per cardiovascular society guidelines, for implantation of
an ICD or CRT-D system for treatment of heart failure or life-threatening ventricular tachyarrhythmia(s). Indication: The device is indicated for the treatment of heart failure or life-threatening ventricular tachyarrhythmia(s).
1884 patients, 80 sites
Complication free survival rate at 5 years for complications related to the RV lead or
SJ4 connector is greater than 92.5%. The following complications will be included in this analysis: Cardiac perforation, Lead dislodgement that occurred greater than 30 days after implant, Lead insulation damage, Lead fracture, Lead/Port damage, Abnormal RV lead performance (abnormal lead defibrillation impedance, abnormal lead pacing impedance, elevated pacing thresholds, loss of capture, loss of defibrillation output, loss of sensing, oversensing, undersensing), Other unexpected complications that are considered related to the RV lead or SJ4 connector
Followup Visits and Length of Followup
Patients will be followed every six months for 5 years
