A Novel Device for Intraoperative Direct Visualization of a Pressurized Root in Aortic Valve Repair.

ABSTRACT:

Purpose

One major challenge in generating reproducible aortic valve (AV) repair results is the inability to assess AV morphology under physiologic pressure. A transparent intraoperative AV visualization device was designed and manufactured.

Description

This device comprises an open proximal end, a cantilevered edge to allow attachment of the device to the aorta or graft, a distal viewing surface, and 2 side ports for fluid delivery and air removal.

Evaluation

The performance of the device was evaluated ex vivo using normal porcine AV in situ (n = 3), porcine AV after valve-sparing aortic root replacement (VSARR) (n = 3), porcine pulmonary valve in the Ross procedure (n = 3), and in 3 patients who underwent VSARR. AV morphology was clearly visualized using the device i
