Brief Summary:
The primary objectives of this registry is to correlate the amount of fibrosis as documented on Electrocardiogram (ECG) gated Computed Tomography (CT) scans with ease of advancing sheaths over the leads through the SVC zone during lead extraction.

Condition or disease
Mechanical Complication of Cardiac Electronic Device

Detailed Description:
This is a multi-center, prospective, observational registry study which plans to enroll approximately 200 patients referred for Cardiac Implantable Electronic Device(CIED) lead extraction at one of the five study centers. The objective of this study is to determine whether a correlation exists between fibrosis detected on ECG gated cardiac CT and the ease of lead extraction as measured by need for extraction energy. All patients will be followed for 30 days post-lead extraction to assess vital status and re-hospitalizations via phone call

Outcome Measures
Go to 
Top of Page Study Description Study Design Groups and Cohorts Outcome Measures Eligibility Criteria Contacts and Locations More Information

Primary Outcome Measures :
  1. Correlation of the presence and degree of fibrosis as determined by ECG gated cardiac CT with the presence and degree of fibrosis determined by ease of extraction sheath advancement [ Time Frame: 30 days ]
    The presence and degree of fibrosis determined by the ease of extraction sheath advancement will be evaluated in three zones. Zone 1 will be the area before the Superior Vena Cava (SVC), Zone 2 in the SVC and Zone 3 after the SVC


Secondary Outcome Measures :
  1. Percentage of ECG gated CT scans that show fibrosis [ Time Frame: 30 days ]
    The percentage of ECG gated CT scans will be determined by scans that show little to no SVC (Zone 2) fibrosis, show little to no Zone 1 fibrosis, show little to no Zone 3 fibrosis, cardiac perforation, extravascular lead location

  2. Major complications as defined by Heart Rhythm Society (HRS) 2017 consensus guidelines [ Time Frame: 30 days ]
    major complications

  3. Minor complications as defined by HRS 2017 consensus guidelines [ Time Frame: 30 days ]
    minor complications

  4. Mortality [ Time Frame: 30 days ]
    Death assessed

  5. Procedural outcomes [ Time Frame: 30 days ]
    Operator ease of extraction (grade 1-5)

  6. Fluoroscopy time [ Time Frame: 30 days ]
    Fluoroscopy duration of time

  7. Pathological reports from extracted leads [ Time Frame: 30 days ]
    Pathology reports from extracted leads if available

  8. Hospitalizations directly related to the extraction of leads or procedure related [ Time Frame: 30 days ]
    Number of hospitalizations related to the extraction of leads or procedure related within 30 days post procedure
