Successful Handmade Monobloc Aortomitral Valve Replacement for Extensive Aortic Root Abscess

Aortic root abscess is one of the most catastrophic complications of aortic valve endocarditis. Complete debridement 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 debridement, 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 debridement. (C) 2021 by The Society of Thoracic Surgeons

Automated summary

Aortic root abscess is a severe complication of aortic valve endocarditis that requires complete debridement during surgical treatment, sometimes involving reconstruction of the aortic annulus. In cases of extensive abscess, a handmade aortomitral monobloc valve can be utilized to achieve complete debridement.
