Perceval Valve Implantation: Technical Details and Echocardiographic Assessment.

The Perceval valve (LivaNova, London, United Kingdom) is a collapsible, sutureless bioprosthetic aortic valve. This novel design is well suited for minimally invasive approaches and has particular advantages for patients with small, calcified annuli. The implantation technique is unique, and echocardiographic assessments of valve cage shape, angulation, and height are essential. The following discussion provides a framework of technical and sonographic considerations to help surgical teams achieve reproducible success with Perceval valve deployment.
