Abstract:
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.

Heart Valves
The AV valves prevent the backflow of blood from the ventricles to the atria during ventricular contraction. These valves function with the assistance of the chordae tendineae and papillary muscles. When the ventricles are relaxed, the chordae tendineae are slack, allowing blood to flow from the atria into the...
Detailed Structure and Function of Lymph Nodes
From a histological perspective, lymph nodes can be split into two main areas: the superficial cortex and the deep medulla. The outer cortex is populated by dendritic cells, macrophages, and B lymphocytes, which are densely packed into follicles. When these B-lymphocytes are presented...
