Pacemaker and Implantable Cardioverter Defibrillator Implants

Initial Implantation Complications: Pacemaker and Implantable Cardioverter Defibrillator

2022, N =799

In 2022, Cleveland Clinic performed 452 pacemaker and 347 implantable cardioverter defibrillator (ICD) implants, for a total of 799 procedures with low rates of complications. The device-related infection rate within 90 days of implant was 0.3%. The overall complication rate for these implanted device procedures was 2.0%.ᵃ There were no procedure-related deaths.

ᵃInitial implant: No prior device had been implanted (includes all devices for bradycardia and tachycardia); excludes special devices such as laptop and loop recorders. Percentage totals were rounded.

The overall major complication rate is inclusive of lead dislodgements, pneumothorax requiring a chest tube, device-related infections, and pericardial effusions with percutaneous interventions.

Lead Extraction Procedure: Volume, Success, and In-Hospital Mortality

2018 – 2022

Electrophysiologists at Cleveland Clinic perform a high number of lead extractions. Many of these patients have complex conditions that result in referral to Cleveland Clinic physicians. Leads may need removal because of malfunction, blocked blood vessels, or infection. In most cases, the leads can be removed without opening the chest or heart. A multidisciplinary approach is utilized to minimize the risk for this procedure.

A total of 861 lead extraction procedures were performed to remove 1551 leads at Cleveland Clinic from 2018 through 2022. The overall clinical success rateᵃ was 95.9%. In-hospital mortalityᵇ was 0.12% vs the benchmark¹ of 1.2%.

ᵃClinical success is defined as removal of all targeted leads and lead material from the vascular space or retention of a small portion of the lead (< 4 cm) that does not negatively impact the outcome goals of the procedure.

ᵇIn-hospital mortality was calculated by dividing the total number of in-hospital deaths (N = 1) by the total number of lead extraction procedures (N = 861).

Device Clinic Evaluations: Volume

2022, N = 83,078

Cleveland Clinic was the first hospital in the country to integrate a patient database for pacemaker and implantable cardioverter defibrillator follow-up with electronic medical records. This innovative approach to follow-up allows staff to keep track of patients’ health conditions regardless of the patient's location. Remote monitoring is also associated with increased longevity and decreased need for in-person follow-up.

The Miller Family Heart, Vascular & Thoracic Institute uses the MyChart® function in Epic, Cleveland Clinic’s electronic medical record system, to quickly notify patients of their device status.
