  Visual Summary. Clinical Timeline Demonstrating Delayed Fragmentation and Intracardiac Migration of an Iliac Venous Stent With Multimodality Imaging Findings, Surgical Management, and Key Learning Points CTA = computed tomography angiography; IVC = inferior vena cava; RV = right ventricle; TEE = transesophageal echocardiography; TTE = transthoracic echocardiography.
