Dear user, we’re proud to present you version#2 of our CircAdapt educational tool. This second version has unmet possibilities to simulate normal and pathological cardiac conditions, ranging from valvular disorders to intra-cardiac shunts, heart failure, infarcts and asyncronous electrical activation. We have done our utmost best to present you with an intuitive Graphical User Interface (GUI), but we admit that not every choice made might be the best one. We hence invite you to submit comments and suggestions for improvements related to the cosmetics and user-friendliness of version#2 to info@circadapt.org We will use this information for version#3, planned to be released spring 2023.
