Successful Handmade Monobloc Aortomitral Valve Replacement for Extensive Aortic Root Abscess.

Abstract

Aortic root abscess is one of the most catastrophic complications of aortic valve endocarditis. Complete débridement is recommended regardless of the kind of infected lesion. A 37-year-old man with extensive aortic root abscess due to prosthetic aortic valve endocarditis was surgically treated. The main lesion was the aortomitral continuity extending to the commissure between the left and right coronary cusps. After débridement, the aortic annulus underneath the left coronary artery was reconstructed using a handmade aortomitral monobloc valve without aortic annuloplasty. This valve was required for the extensive root abscess of the left and noncoronary sinus to achieve complete débridement.
