Attain Performa™ Left Ventricular (LV) Quadripolar Leads Chronic Performance Study

Study Overview
=================
Brief Summary
-----------------
Lead survivability will be summarized.

Detailed Description
-----------------
The purpose of this study is to evaluate long-term performance of the Attain Performa™ LV Leads. This evaluation is based on the number of lead-related complications occurring during the study compared to the number of leads enrolled in the study. The leads will be followed for 5 years after implant. This study is required by FDA as a condition of approval of the Attain Performa™ LV Leads. This study is conducted within Medtronic's post-market surveillance platform.

What is the study measuring?
-----------------
Primary Outcome Measures

| Outcome Measure | Measure Description | Time Frame |
| --- | --- | --- |
| Lead complication | Survival analysis will be used to analyze the lead. Lead status will be reported as a function of time post-implant for all leads in the study. Lead related complications include but are not limited to: failure to capture, abnormal sensing, threshold rise, abnormal impedance, insulation breach, conductor fracture, extracardiac stimulation, lead dislodgement, cardiac perforation, structural lead failure. | 5 years | 

Secondary Outcome Measures

| Outcome Measure | Measure Description | Time Frame |
| --- | --- | --- |
| Types of lead-related adverse device effects | Summary statistics will be used to report types and rates of lead related adverse device effects (ADE). Examples of ADEs include but are not limited to: failure to capture, abnormal sensing, threshold rise, abnormal impedance, insulation breach, conductor fracture, extracardiac stimulation, lead dislodgement, cardiac perforation, structural lead failure. | 5 years | 
| Returned lead analysis | A listing of analysis results of all Attain Performa study leads which are explanted and returned for analysis will be reported. | 5 years | 
| Lead survival estimate by model | An analysis will be conducted at the end of the study to provide comparative statistics on the safety performance of each individual lead model. | 5 years |
