From: Long-segmental middle aortic coarctation: a rare case first diagnosed by transthoracic echocardiography

Fig. 1

TTE and abdominal vascular ultrasound showed long segmental middle aortic coarctation. A M mode showed the left ventricular hypertrophy with a reduced ejection fraction to 44.8%. B, C The suprasternal view showed no aortic coarctation in the isthmus. DG With a slight adjustment of the probe in the parasternal long-axis view of the left ventricle, the diameter of the thoracic descending aorta behind the left atrium gradually decreased. HJ The longitudinal axis of the thoracic descending aorta showed a segmental narrowing with a calcified plaque(arrow) in the thoracic descending aorta below the level of the atrioventricular sulcus, Color Doppler showed a turbulent flow in the narrowing segment with a peak velocity of 829 cm/s. KL Abdominal vascular ultrasound showed a long segment narrowing (bracket) of descending abdominal aorta above the level of the superior mesenteric artery. LV left ventricle, LA left atrium, RVOT right ventricular outflow tract, RV right ventricle, SMA superior mesenteric artery, AAO ascending aorta, DAO descending aorta, ARCH aortic arch, LCCA left common carotid artery, LSCA left subclavian artery
