Leadless Pacemaker

Leadless Pacemaker

A leadless pacemaker is a self-contained device implanted directly inside the heart without the need for wires (leads), offering a minimally invasive alternative for select patients. Because there is no chest incision or pocket and no leads, certain complications associated with traditional pacemakers are avoided.

What to Expect During the Procedure

  • The procedure is performed under local anesthesia with sedation, meaning you will be awake but comfortable.
  • Rather than an incision near the collarbone, the device is delivered through a catheter inserted into a vein in the groin.
  • The self-contained pacemaker is implanted directly inside the heart and secured to the heart wall.
  • The device will be tested to ensure proper function before the catheter is removed.

Risks Involved

While leadless pacemaker implantation is generally safe, potential risks include:

  • Bleeding or bruising at the groin insertion site.
  • Minor bleeding at the groin site, which can typically be controlled by applying firm pressure for 30 minutes.
  • Cardiac perforation, a rare complication that may require a drain to be placed.
  • Device dislodgement (rare).
  • Blood clots (rare).

What to Expect After the Procedure

  • Minor bruising or soreness at the groin site, which may take a few weeks to resolve.
  • Because there is no chest pocket, recovery is often quicker than with a traditional pacemaker.
  • A follow-up appointment will be scheduled to check device function.

When to Seek Medical Attention

Go to the Emergency Room if you experience:

  • Severe pain or increasing swelling in the groin where the catheter was inserted.
  • Uncontrolled bleeding at the groin site.
  • Persistent dizziness, shortness of breath, or extreme fatigue.
  • Palpitations or an irregular heartbeat.

Follow-Up Care

  • You will have a follow-up visit to check device function.
  • Routine checks are needed to monitor battery life and performance.
  • If you have any concerns or unusual symptoms, contact our office for further evaluation.
