An observational feasibility study.
A community hospital, single-institutional study.
Eighty consecutive adult patients undergoing cardiac surgery.
All patients were examined with 3D epicardial echocardiography before and after cardiopulmonary bypass; x-plane, live 3D, and 3D full-volume imaging modalities were systematically recorded. Feasibility and acquisition time were assessed. The image quality was evaluated by 3 independent surgeons.
Four sequential positions were determined to achieve a complete 3D heart examination focused on the structure of most interest. Acquisition plus elaboration did not require more than 20 minutes.
Three-dimensional epicardial echocardiography is feasible, and in the x-plane modality it is quicker than standard epicardial 2-dimensional examination. According to the judgment of independent observers, it provides high-quality and reproducible images, which are particularly valuable for mitral valve repair.
