What happens if a pacemaker lead comes loose?

Pacemaker lead fracture is one of the most common causes of pacemaker malfunction and is most frequently associated with weight lifting or chest trauma. These patients usually present with symptoms of dizziness, syncope, chest discomfort, and palpitations or less commonly with extracardiac symptoms.

How easy is it to dislodge pacemaker leads?

The incidence of early displacements is 1% in VVI pacemakers and 5.2% in DDD pacemakers (3.8% of the cases affecting atrial leads and 1.4% ventricular leads). Acceptable displacement rates should probably be less than 1 percent for ventricular leads and no more than 2 to 3 percent for atrial leads.

Can a pacemaker be dislodged?

“Pacemakers are made up of two main components, a generator and a lead that carries electrical impulses to the heart,” Janeira writes in Discover. “Often the lead tip is screwed directly into the heart muscle, but in rare cases it can dislodge and cease to stimulate the heart.”

Are pacemaker leads MRI safe?

MRI examinations can be performed safely in patients with non-MR compatible cardiac devices, including those who are pacemaker-dependent or have abandoned leads, according to a study published in Radiology: Cardiothoracic Imaging.

Can a MRI be used for an abandoned pacemaker?

An investigation by Higgins, et al. (2014) that involved patients with abandoned cardiac pacemaker and implantable cardioverter defibrillator (ICD) leads reported that the use of MRI in patients with abandoned cardiac device leads may be feasible when performed under careful monitoring conditions and with other precautions in place.

Is it safe to use an abandoned pacemaker lead?

Langman DA, et al. Abandoned pacemaker leads are a potential risk for patients undergoing MRI. Pacing Clin Electrophysiol 2011;34:1051-3. Langman DA, et al. Pacemaker lead tip heating in abandoned and pacemaker-attached leads at 1.5 Tesla MRI.

What are the risks of radiography of a pacemaker?

Radiography of Pacemakers and Implantable Cardioverter Defibrillators. Complications can include pneumothorax, hematoma (pocket or mediastinal), myocardial perforation with or without tamponade, hardware infection, inappropriate lead placement or pacing (such as of the diaphragm), and inappropriate shocks [ 4, 5 ].

Do you need an MRI for epicardial pacing leads?
