CTICasesDislodged Transcatheter Aortic Valve Replacement (TAVR) requiring Surgical Retrieval
Imaging findings
A young patient with aortic valve endocarditis presented with pulmonary edema. Following an attempted transcatheter aortic valve replacement (TAVR), the valve dislodged, appearing to bounce within the aortic annulus before migrating into the left ventricle. This necessitated a median sternotomy for surgical retrieval of the valve.
Key takeaways
Transcatheter aortic valve replacement (TAVR) in younger patients, particularly those with a non-calcified aortic annulus or friable tissue due to endocarditis, carries an increased risk of valve dislodgement. The lack of calcification may prevent adequate seating and purchase of the valve, requiring emergent surgical intervention to retrieve the embolized device.
