MITEA or (MR-Informed Three-dimensional Echocardiography Analysis) dataset consists of annotated 3D echocardiography (3DE) data using labels derived from paired CMR scans acquired in a mixed cohort of 134 human subjects (82 healthy controls and 52 patients with acquired cardiac disease). For each subject, two 3DE scans (scan and rescan, in a randomised order) are available, at 2 image frames corresponding to end-diastole and end-systole. For each image, segmentations are also provided. Labelled regions are of the left ventricular myocardium (class value 1) and cavity (class value 2), which can be used for the quantification of LV systolic function and mass. A pre-trained deep learning model (based on nnU‑Net) is also made available.
