Transcatheter removal of permanent dual-chamber leadless pacemaker, including imaging guidance (eg, fluoroscopy, venous ultrasound, right atrial angiography, right ventriculography, femoral venography), when performed; right atrial pacemaker component

A transcatheter removal of a permanent dual-chamber leadless pacemaker involves the extraction of a specialized cardiac device that is implanted within the heart to regulate its rhythm. This procedure specifically targets the right atrial component of the pacemaker system, which is designed to function without traditional leads. The leadless pacemaker consists of a pulse generator that contains a battery and an electrode, allowing it to deliver electrical impulses directly to the heart muscle. The dual-chamber system is particularly beneficial as it can stimulate both the right atrium and right ventricle, ensuring synchronized heart contractions. The removal of this device may be necessary in various clinical scenarios, such as when the pacemaker has been displaced, infected, or when the patient develops heart failure that necessitates the implantation of a different device, such as a cardiac resynchronization therapy device. The procedure is performed using imaging guidance techniques, including fluoroscopy, venous ultrasound, and angiography, to ensure accurate placement and retrieval of the pacemaker components. This minimally invasive approach allows for the safe extraction of the pacemaker while minimizing trauma to the surrounding tissues.
