Top 5 medical apps – Latest medical apps on rheumatic mitral regurgitation
The expedient members from appsread.com closely analyses about top 5 medical apps and brings conclusion with regard to latest news on rheumatic mitral regurgitation. The inflammatory changes associated with the rheumatic process transforms the mitral valve into a stiff funnel shaped unit. The latest news on rheumatic mitral regurgitation list out changes brought on by the rheumatic process ending in thickening of the leaflets, tethering of the leaflets due to shortening and thickening of the sub-valvular apparatus as well as fusion of the commissures. This can result in a predominantly stenotic valve, predominantly regurgitate valve or a valve with mixed valve on 2-D echo is well known.
They include thickened leaflets particularly at the tips, elbowing of the anterior mitral leaflet and markedly restricted or immobile posterior leaflet. The shortening of the sub-valvular apparatus results in apical displacement of the cooptation point. The top 5 medical apps analysis about the features which are best appreciated in the parasternal long axis view. In the short axis view, commissural fusion is seen but this is only minimal in predominantly regurgitate lesions.
It is in this top 5 medical apps view that the mitral valve area can be accurately assessed by planimetry. In patients with predominant regurgitate valve, there is significant retraction of the leaflets, resulting in failure of cooptation. This is best appreciated in the short axis as well as the parasternal long axis views. The extent of the mal-cooptation of the leaflets is proportional to the MR severity.
The gold standard for the diagnosis of mitral valve prolapse MVP is 2-D echocardiography. The latest news on rheumatic mitral regurgitation suggests that MVP is seen as displacement of the mitral leaflets, into the LA beyond the line connecting the annular-hinge points, of 2mm or more. The diagnosis criteria have been refined in light of 3-D echocardiography data which showed the mitral annulus to be saddle shaped and not planar. The latest news on rheumatic mitral regurgitation talks about the diagnostic criteria which has avoided over diagnosis of MVP. The top 5 medical apps reveals about the early studies which have estimated the prevalence of MVP to be 5-15 %. It is also learnt from latest news on rheumatic mitral regurgitation that observational studies utilizing more potent rigorous criteria which have expediently demonstrated a more accurate prevalence of 1.6-2.4 %.
This top 5 medical apps refined diagnosis criterion allows the diagnosis of MVP to be made only from the parasternal long axis and the apical long axis view. This is because these imaging views pass through the highest point of the annulus while in the apical four chamber view the imaging plane passes through the lowest point of the annulus. The apparent displacement of the leaflets into the LA in the apical four chamber view does not represent prolapse of the mitral valve.
