Abstract:
Transvenous lead extraction is performed for device infection, lead failure, or to provide access for additional leads/device upgrade. A patient-centered risk assessment for transvenous lead extraction can be determined using a combination of clinical factors and several imaging modalities. Predicting a complex lead extraction, for example, one that will require powered tools or the use of a femoral approach, is aided by pre-procedural imaging and clinical assessment. Procedural imaging utilizing fluoroscopy, transesophageal echocardiography, and intracardiac echocardiography during an extraction can improve safety and identify complications rapidly.

Definition and Purpose
An X-ray, or radiograph, is a non-invasive method that uses ionizing radiation to take images of internal structures. It is mainly used in cardiac imaging to examine the heart, lungs, and major blood vessels, aiming to identify abnormalities in the heart's size, shape, and position, such as heart failure, congenital defects, and vascular...
