CTICasesAcorn CorCap Cardiac Support Device
Imaging findings
A 59-year-old woman with heart failure has a chest radiograph showing a structure following the contours of the ventricles and lying against the pericardium, corresponding to a mesh sewn around the ventricles.
Key takeaways
The Acorn CorCap is a surgically implanted mesh cardiac support device wrapped around the ventricles to restrict remodeling and dilatation in heart failure with mitral regurgitation, developed in the mid-2000s but never FDA-approved and now rarely seen. Recognizing the ventricular mesh on imaging identifies this historical device rather than a pathologic finding.
