The use of Twitter in healthcare has allowed healthcare professionals the opportunity to break down boundaries with patients. Previous Twitter studies relating to cardiology have explored features of tweets associated with professional organisations and journals focusing on cardiology. However, there have been few studies into tweets associated with congenital heart disease (CHD). This article shows the extracted and analysed study of 2,854 tweets associated with congenital heart disease. The results highlighted that the presence of a higher number of URLs, hashtags or followers didn't lead to a high number of retweets. Content analysis was carried out on 250 randomly selected tweets from the sample. Analysis of tweet content found that information was shared rather than being sought, with content sharing being the most popular style of tweet. This highlighted the power of Twitter in offering access to support to CHD suffers and families via an online platform. Support exists in various means, whether it is sharing experiences or learning more about CHD health campaigns.
