Reconstruction of the mitral-aortic intervalvular fibrosa for infective endocarditis carries a high operative risk for the first year, though current outcomes have improved compared to the past.
Reconstruction of the mitral-aortic intervalvular fibrosa in infective endocarditis is a complex procedure with high initial operative risk that stabilizes after the first year.
Elevated first-year risk after mitral-aortic intervalvular fibrosa reconstruction warrants cautious selection; leaves open the need for prospective data on timing and technique.
Destruction of the mitral-aortic (or mitroaortic) intervalvular fibrosa (IVF) by infective endocarditis is a marker of advanced pathology. Patients are at high risk, as they are sicker, have more comorbidities and have more advanced pathology, requiring a difficult operation that includes debriding and reconstructing the IVF. The anatomy and surgical techniques for that reconstruction are presented and discussed. Operative risk is high and remains high for the first year, before becoming equivalent to that of conventional operations for endocarditis. Current outcomes are better than in the past, but there is room for further improvement.

Pettersson et al. (2014) conducted a review in Infective endocarditis with destruction of the mitral-aortic intervalvular fibrosa. Reconstruction of the mitral-aortic intervalvular fibrosa was evaluated. Reconstruction of the mitral-aortic intervalvular fibrosa for infective endocarditis carries a high operative risk for the first year, though current outcomes have improved compared to the past.
