(tt2732) F, 68 y. Sonos 2000. Chest pain and LBBB. Aortic dissection type A, anterior wall of ascending aorta (see intimal mobile flap in 2D parasternal and jugular views, and M-mode) between sino-tubular junction and brachiocephalic branch. Note color Doppler flow in aortic true lumen distal to flap in arch. Associated moderate AR. See also intra-operative TE exam (te0373).
胸痛及左束支传导阻滞(LBBB)。A型主动脉夹层, 升主动脉前壁 (2D胸骨旁和颈动脉视图及M型中可见可移动的内膜皮瓣) 窦管交界处和头臂干之间。 注意主动脉真腔内,即主动脉弓内皮瓣的远端的彩色多普勒血流。符合中度主动脉瓣返流。亦可见于术中食道彩超检查(te0373)
