Ectopic thyroid tissue in the left ventricular outflow tract Doan Baykut, MD, Udo Fiegen, MD, Arno Krian, MD, Andreas Thiel, MD The Annals of Thoracic Surgery Volume 69, Issue 2, Pages 620-621 (February 2000) DOI: 10.1016/S0003-4975(99)01344-2
Fig 1 Preoperative transesophageal echocardiographic image of the left ventricular outflow tract and interventricular septum. The first tumor is located directly under the aortic valve, while the second tumor is intraseptal, thinly covered by myocardium. (AV = aortic valve; IVS = interventricular septum; LV = left ventricle; LVOT = left ventricular outflow tract; TU = tumor).

Fig 2 Intraoperative situs. The left ventricular outflow tract is exposed through the aortic valve. The arrow marks the tumor partly obstructing the outflow tract. The Annals of Thoracic Surgery 2000 69, 620-621DOI: (10.1016/S0003-4975(99)01344-2)
Fig 3 Transesophageal echocardiographic image after tumor resection. The left ventricular outflow tract is now free of any obstruction. The primary tumor site appears slightly excavated (arrow). The second tumor, which was left in situ, is partly visible. (AO = aorta; LVOT = left ventricular outflow tract; NCC = noncoronary cusp of the aortic valve; RCC = right coronary cusp of the aortic valve.)
