A patient with a history of aortic valve endocarditis and surgical debridement presented with acute congestive heart failure because of severe aortic stenosis. During valve replacement surgery, an aortic annular enlargement was required to overcome a potential patient-prosthesis mismatch. We describe the use of a novel, bioresorbable, acellular xenograft for the enlargement patch. This material is expected to remodel into native patient tissue over time. This case offers an alternative implant for left heart reconstruction using a regenerative patch.
