The specialised articles on this website were written by medical experts, and are intended for patients and their families, the interested public, doctors, medical staff and the media.

The website provides information on diagnosis and therapy of congenital heart defects, presents current research projects and results, and gives contact details of self-help groups, advice centres and medical institutions for patients with congenital heart defects.

The Competence Network for Congenital Heart Defects is sponsored by the German Federal Ministry of Education and Research (BMBF) as part of the ‘Health Research: Scientific Research for the People’ programme. The network’s objective is to improve the treatment available to children, adolescents and adults suffering from congenital heart defects.

Legal information

1. Disclaimer

Knowledge in the field of medicine is subject to continuous change as research progresses and clinical experience is gained. The authors and experts of this website take great care to present factual information in a form that can be easily understood. By no means does the information provided by the Competence Network for Congenital Heart Defects substitute a personal examination or diagnosis performed by a doctor. No liability is therefore accepted for content made available by the operators of this website, nor for contributions made by authors and experts, except in cases of deliberate or grossly negligent misinformation. The same applies to content made available by third parties, which are merely linked to this website. All offers are subject to change and are not binding. The author expressly reserves the right to amend, update, delete or (temporarily or permanently) cease the publication of parts or all of this website without prior notice.

2. References and links

The author accepts no liability for direct or indirect references to third-party websites (hyperlinks) outside the author’s area of responsibility. The author hereby states that there was no recognisable illegal content on any of the linked web pages at the time of placing the link. The author has no influence whatsoever on the current and future design, content or authorship of the linked websites. The author therefore dissociates themselves explicitly from any content of any linked pages which were modified after the time of linkage. This holds true for all links and references within this website. Any illegal, incorrect or incomplete information, and especially any damages caused by the usage or non-usage of that information, is the sole responsibility of the provider of the linked page, not the referrer to that page.

3. Copyright

All texts and images and the layout of these web pages are protected worldwide by copyright law. The contents of this website may be used for private purposes. To use the texts for other purposes, permission must be obtained from the owner of this website. All product designations and trade names mentioned on this website are the property of their respective owners and are as such protected by trademark and/or patent law. The right of reply may be exercised only under the terms specified in §10 of the German interstate treaty on media services (MdStV).

4. Data protection

In cases where users have the opportunity to enter personal or business details (names, e-mail or postal addresses) on this website, the provision of such data by the user is expressly voluntary. Third parties may not use contact details published in the editorial notes or a comparable section of this website (such as e-mail and postal addresses, or telephone and fax numbers) to send any information not explicitly requested by the person concerned. We explicitly reserve the right to press legal charges against senders of so-called spam mails who violate this ban.

5. Severability clause

Should one of the above clauses/provisions be or become entirely or partly invalid on the basis of legal regulations and directives or due to changes in legislation, it shall be substituted by whichever valid clause or provision most closely approximates the intended purpose of the original. The remaining provisions shall not be affected, and shall continue to be valid and enforceable to the fullest extent permitted by law.
