Neo-Leaflet Failure after Comprehensive Aortic Root and Valve Reconstruction.
The comprehensive aortic root and valve reconstruction (CARVAR) technique comprises two main procedures, which are aortic root reduction using prosthetic rings and neo-leaflet reconstruction using a pericardial patch. Although concerns about durability of the pericardial neo-leaflet have been raised in the CARVAR technique, complications related to leaflet reconstruction have not been reported to date. The present report describes two cases of complications associated with leaflet reconstruction. After resecting the reconstructed leaflets, aortic valve replacement was performed in the patients. Careful and close follow-up is required for patients who had undergone CARVAR surgery, and aortic valve surgery should be performed in a timely manner if needed.
