FIGURE 3 Intraoperative TEE and surgical images. (A) Pre-TEE shows an aneurysmal dilation of left main coronary artery (LMCA) origin. (B) Color Doppler imaging with systolic aliased flow in the sinus node artery (SNA). (C-D) Pre-TEE bicaval view reveals an aneurysm-like fistula from left main coronary to right atrium (RA), which adjacent to superior vena cava (SVC). (E) A collapsed left coronary aneurysm under cardiopulmonary bypass. (F) Post-TEE long-axis view reveals a collapsed aneurysm in the posterior of the left atrium. White star represents aneurysm.
