Chest radiography of contemporary trans-catheter cardiovascular devices: a pictorial essay.

Abstract

There is a plethora of cardiovascular devices used for therapy and monitoring, and newer devices are being introduced constantly. As a result of advancement of medical technology and rapid development of such technology to address unmet needs across cardiovascular care, multiple conditions which were previously treated surgically or with medications now benefit from trans-catheter device-based evaluation and management. Moreover, innovation to existing technology has transformed the structural design of many traditional cardiovascular devices, making them safer and enabling easier deployment within the chest (catheter-based versus surgical). A post-procedure chest radiography (CXR) is often the first routine imaging test ordered in these patients. A CXR is a relatively inexpensive and noninvasive imaging tool, which can be obtained at the patient's bedside if needed. Commonly implanted cardiovascular devices can be quite easily checked for appropriate positioning on routine CXRs. Potential complications associated with mal-positioning of such devices may be life-threatening. Such complications often manifest early on CXRs and may not be readily apparent on clinical examination. Prompt recognition of such abnormal radiographic appearances is critical for timely diagnosis and effective management. Clinicians need to be familiar with new devices in order to assess proper placement and identify complications related to mal-positioning. This pictorial essay aims to describe the radiologic appearances of contemporary cardiovascular devices, review indications for their usage and potential complications, and discuss magnetic resonance imaging (MRI) compatibility.
