(A) Two-dimensional TEE, midesophageal short-axis systolic view (63°), demonstrates an AMB within the RVOT that narrows the subinfundibular region. Two-dimensional TEE, transgastric long-axis systolic view (94°) without (B) and with (C) color flow Doppler, demonstrates the subinfundibular narrowing in the region of the AMB with mosaic-appearing turbulence consistent with flow acceleration (arrow) and the pathologic gradients with continuous-wave Doppler (D). AMB, Accessory muscle bundle; PV, pulmonic valve.
