Introduction
Imaging evaluates device position integrity lead complications and associated cardiac or vascular issues and guides management of device related problems. Radiography provides initial assessment while CT and MRI with appropriate safety protocols offer detailed evaluation. Collaboration with electrophysiology and device manufacturers ensures safe imaging practices.
Radiography and Fluoroscopy
Chest radiographs assess lead position generator location and gross complications such as lead fracture or pneumothorax. Fluoroscopy can evaluate lead mobility and guide extraction planning. Radiographic comparison with prior studies helps detect migration or hardware failure.
CT and MRI Considerations
CT provides high resolution assessment of lead course and surrounding structures and is useful for pre extraction planning while MRI requires device specific safety evaluation and programming adjustments. MRI conditional devices allow safe imaging under defined protocols and monitoring. Advanced imaging detects infection erosion and thrombus associated with devices.
Clinical Management
Imaging findings are integrated with clinical signs device interrogation and laboratory data to guide interventions such as extraction revision or antibiotic therapy. Multidisciplinary coordination with cardiology electrophysiology and radiology ensures patient safety. Documentation of device type and manufacturer facilitates imaging planning.
