Description
Summary:The additional ischemic electrocardiographic changes evoked by walking had him undergo revascularization for LAD (Fig. 1e, f). Since cardiac magnetic resonance imaging was rejected due to claustrophobia, three-dimensional (3D) TTE was performed. The 3D apical view demonstrated trabecular formation crosslinking to septal and lateral walls, suggesting that the LV mass was myocardial trabeculation, not a thrombus (Fig. 1g; Videos 4–6); however, the possibility of a concomitant invisible tiny thrombus adjacent to the trabeculation remained. Since the TTE appearance of LV thrombi varies from case to case depending on thrombus age, morphology, and location, two-dimensional imaging has a certain limitation [4]. Declarations Conflict of interest Kei Takahashi, Toru Egashira, Toshimi Kageyama, Tetsuo Oumi, Shigeo Shimizu, Kazunori Moritani, and Hideo Mitamura declare that they have no conflicts of interest.
