Have you ever searched the internet for reliable answers about echocardiography related questions? With WikiEcho, the European Association of Cardiovascular Imaging (EACVI) is now offering a free, up-to-date and reliable online encyclopaedia for all people interested in echocardiography.

A large number of enthusiastic authors have already contributed over the past few months and from December 2012 the website is open to all users. Heart disease medicine Please help to make WikiEcho grow by participating actively in the discussions and writing your own articles.

As in any wiki, contributions and changes will be published immediately, but to reassure you about the quality of the content, WikiEcho has a special feature: articles will be reviewed by an EACVI board of echocardiography experts. Coronary heart disease nhs Watch out for the EACVI logo which indicates approved articles!

We would be glad if WikiEcho becomes your most used and trusted online source in echocardiography.
