Study: NCT03422770

Intervention type: DIAGNOSTIC_TEST
Group type: OTHER
Intervention: Echocardiography
Description: Conventional transthoracic echocardiography will be performed, in addition 3D-imaging and acquisitions with high frame rate. The data from these patients will be anonymized and transferred for post-hoc analysis in dedicated computer software (GE Vingmed, EchoPac 2.0) and in validated machine learning algorithms.
