This report describes the percutaneous extraction of embolized intracardiac inferior vena cava (IVC) filter struts using fluoroscopy and fused intracardiac echocardiography and three-dimensional electroanatomic mapping. Six patients with indwelling IVC filters placed at outside institutions 5 months to 14 years previously presented with cross-sectional imaging of the chest demonstrating fractured IVC filter struts embolized to the myocardial free wall (four patients) or interventricular septum (two patients). All embolized filter struts were successfully retrieved, and open heart surgery was avoided.

Objective: Intracardiopulmonary migration of an inferior vena cava (IVC) filter is an uncommon but potentially life-threatening complication. A previous systematic review including data through 2008 found that the most common cause for migration was operator error and that open thoracotomy was the best first option for management. The aim of this study was to assess the clinical presentation and causes of intracardiopulmonary filter migration, as well as the most commonly used management strategies over the past 15 years.

Silent Brain Infarction (SBI) is increasingly recognized in patients with cardiac conditions, particularly Atrial Fibrillation (AF) in elderly patients and those undergoing Transcatheter Aortic Valve Implantation (TAVI). While these infarcts often go unnoticed due to a lack of acute symptoms, they are associated with a threefold increase in stroke risk and are considered a precursor to ischemic stroke. Moreover, accumulating evidence suggests that SBI may contribute to the development of dementia, depression, and cognitive decline, particularly in the elderly population.

Objectives: Inferior vena cava (IVC) penetration is a prevalent complication following the placement of conical filters. However, there is a paucity of studies examining the penetration in smaller IVC. The objective of this study was to assess the time of penetration, the incidence of serious complications associated with penetration, and the process of IVC wall repair in the smaller IVC following the placement of a conical filter.
