Key result
Modified mechanical Valsalva conduit successfully excludes infected aortic annulus in destructive recurrent endocarditis.
Why the study?
Reoperative aortic valve replacement in destructive recurrent prosthetic aortic valve endocarditis with destroyed aortic annulus and sinus of Valsalva presents technical challenges for secure suture placement.
Case Report
A novel modification of a composite mechanical Valsalva conduit provides a surgical option for complex recurrent prosthetic aortic valve endocarditis with annular and sinus destruction.

May offer a surgical option in complex recurrent prosthetic aortic valve endocarditis; hypothesis-generating and requires validation in larger series.
We describe a novel technical modification for reoperative aortic valve replacement in destructive recurrent prosthetic aortic valve endocarditis. We encountered complex anatomy in a previously operated aortic root wherein the aortic annulus and the right coronary sinus of Valsalva were destroyed. This precluded secure suture placement. We modified a composite mechanical Valsalva conduit to create a separate sinus of Valsalva left in continuity with the mechanical valve. This approach allowed us to exclude the infected right sinus of Valsalva and the corresponding aortic annulus.

Barua et al. (2024) conducted a case report in Destructive recurrent prosthetic aortic valve endocarditis. Modified composite mechanical Valsalva conduit was evaluated. A modified composite mechanical Valsalva conduit allowed for the exclusion of the infected right sinus of Valsalva and corresponding aortic annulus in destructive recurrent endocarditis.
