This grid is the typicaldesignation of body materials. Slight variations may occur due to raw material availability.1) Note the material designation imprinted on the valve body or associated tag. The marking includes the valve style, size letter, and body material.
Radial immunodiffusion (RID) is a technique that can quantitatively. determine the concentration of an antigen. Unlike many gel and liquid. precipitation techniques which qualitatively detect antigen, RID is a. sensitive quantitative technique that is often used clinically to detect. patient levels of blood proteins.
Aetna considers minimally invasive, off-pump Maze procedures, also known as thoracoscopic off-pump surgical ablation (TOPS), experimental and investigational for atrial fibrillation or flutter because there is insufficient evidence of their effectiveness. See also CPB 0019 - Holter Monitors.The Maze procedure is a surgical treatment of atrial fibrillation (AF) in which multiple atrial incisions interrupt the pathogenic reentrant circuits and also direct the sinus impulses to the AV node along a specified route.etna considers minimally invasive, off-pump Maze procedures, also known as thoracoscopic off-pump surgical ablation (TOPS), experimental and investigational for atrial fibrillation or flutter because there is insufficient evidence of their effectiveness.
