Personalized CRT - MPP Post Approval Study

Medtronic market-released cardiac resynchronization therapy (CRT) Quadripolar (Quad) systems approved for commercial release with the Multiple Point Pacing (MPP) feature were eligible to contribute to the Post-Approval Study (PAS) objectives. Products with MPP capabilities receiving appropriate license or regulatory approval during the conduct of the PAS were included and contributed to the PAS objectives upon commercial release. CRT is an established pacing therapy for patients with heart failure (HF). CRT provides atrial- synchronized biventricular (BiV) pacing using standard pacing technology combined with a special third lead that is implanted via the coronary sinus and positioned in a cardiac vein to sense and/or pace the left ventricle (LV). Following a sensed atrial contraction or atrial paced event, both ventricles are stimulated to synchronize their contraction. The MPP feature is designed to allow a second LV pace to occur in LV Only or BiV pace configurations. In the LV Only pace configuration, the LV paces occur simultaneously or sequentially (LV- LV), as applicable by product. When Bi-V pacing is enabled, the RV pace can be delivered either before or after the LV paces, with the order determined by the programmed Ventricular Pacing Configuration. The MPP PAS was a global, prospective, observational multi-center study. Patients implanted with an eligible CRT Quad system were enrolled and followed in the Product Surveillance Registry per the expected standard of care practices of their care provider.
