Patients will be followed for the duration of the PAS. This study is required by FDA as a condition of approval of the Model 4798 LV lead and is integrated within the Product Surveillance Registry (PSR).


The Attain Stability Quad (ASQ) PAS is a multi-center, single arm, prospective observational study. However, in the US, retrospective enrollments from participants in the IDE study (IDE #G170020) are allowed.
