About

TEE Alternative Views

This app offers a unique learning environment for understanding complex 3D heart structures through 19 non-standard 2D echocardiographic views. It combines a rotatable 3D heart model with associated TEE clips, allowing users to visualize internal cardiac anatomy and perform more comprehensive studies.

Highlights
  • 19 non-standard 2D TEE views
  • Rotatable 3D heart model
  • Interactive echocardiographic plane
  • TEE clip visualization
  • Internal cardiac structure reveal
  • Enhanced TEE study learning
Read full description

The primary challenge in learning TEE is translating the two dimensional echocardiographic image into a visualization of the complex three-dimensional (3D) structure of the heart. This TEE Alternative Views app provides a learning environment where users can explore 19 non-standard but complimentary 2D TEE views using two visualization methods simultaneously: (1) a rotatable 3D heart model with an echocardiographic plane and (2) the associated TEE clip. The 3D heart model and echo plane can be rotated, helping to relate the echocardiographic image to heart structures. Part of the heart above the echo plane can be removed, revealing the internal cardiac structures that correspond to the TEE image. This app will enable the user to perform a more complete TEE study than can be obtained from the 20 standard TEE views. For the 20 standard TEE views, please refer to our TEE Standard Views app. The 19 alternative TEE views illustrated in this app are: Coronary Sinus View (100 Degrees) Coronary Sinus View (0 Degrees) Tricuspid Valve Transgastric Short Axis View Tricuspid Valve Mid-Esophageal View Pulmonic Valve Transgastric View Pulmonary Artery Mid Esophageal Right Coronary Artery View Coronary Arteries View Left Pulmonary Veins View Right Pulmonary Veins View Right Upper Pulmonary Vein View Arch Innominate Artery View Arch Left Common Carotid Artery (LCCA) View Arch Subclavian (LSCA) View Five Chamber View Hepatic Vein View Left Atrial Appendage View 1 Left Atrial Appendage View 2 Superior and Inferior Vena Cava View

Verdict

The call

The clearest difference is price: CathSource at Free against TEE Alternative Views's $4.99. CathSource also leads on ratings volume (23 vs 1) and update cadence (every 2 months vs every 6 months).
