Why the study?
Severe peri-annular tissue impairment in aortic root infective endocarditis can hamper successful surgical reconstruction, risking dehiscence and anterior mitral leaflet retraction.
Does sub-annular implantation of a pericardial valved conduit improve outcomes in patients with disruptive aortic root endocarditis?

Does sub-annular implantation of a pericardial valved conduit improve outcomes in patients with disruptive aortic root endocarditis?
Answers are grounded in this paper and cite their sources.
Sub-annular implantation of a pericardial valved conduit for disruptive aortic root endocarditis is a promising technique that avoids tension on friable structures and showed no graft reinfection at 13 months.
Infective endocarditis (IE) with extensive annular disruption and aortic root involvement carries an ominous prognosis (1,2). The broad and severe impairment of the peri-annular tissues at the level of the interventricular septum and mitro-aortic continuity may hamper a successful surgical reconstruction, with dehiscence and retraction of the anterior mitral leaflet (AML) being a possible dreadful complication (3,4). Here we present our technique for root replacement (Bentall) that involves a sub-annular implantation of a 100% pericardial valved conduit (BioconduitTM, Biointegral Surgical, Inc., Ontario, Canada).

Eusanio et al. (2019) conducted a case report in Aortic root endocarditis (n=22). Sub-annular implantation of a pericardial valved conduit (Biointegral Bioconduit) was evaluated on Survival, graft reinfection, and structural valve deterioration at follow-up.
