Modality: Anatomic specimen Orientation: Outflow tract view from left ventricular apex
Description: Looking up the aortic outflow
from the apex of the left ventricle, there is a well circumscribed subaortic
fibrous ring (SAR)
causing severe subaortic stenosis. This ring is just inferior to the aortic
valve leaflets and extends through the area where the anterior leaflet of
the mitral valve (MV)
and aortic valve are in fibrous continuity. There is a ventricular septal
defect (VSD),
that had been previously surgically repaired, inferior to the subaortic
fibrous ring. The patch on the right ventricular surface covering the
ventricular septal defect orifice is not visualized. Institution: The Congenital Heart Institute of Florida (CHIF) Image Label: A070900-24a Source of Image: Van Mierop Archive, University of Florida, Gainesville, Florida Image Certification: AWG Rating: 5 January 2013

Modality: Anatomic specimen Orientation: Opened left ventricular outflow tract view Description: The subaortic fibrous ring (yellow dots) and left ventricular outflow tract have been opened, using a single cut, demonstrating the severe subaortic stenosis. It extends through the area where the anterior leaflet of the mitral valve and the aortic valve are in fibrous continuity. The aortic valve (AoV) is thickened and is bicuspid. Note the high take off of the right coronary orifice (RCO). The left coronary orifice (LCO) and left main coronary artery have been transected. (VSD-ventricular septal defect). Contributor: Diane E.

Modality: Three dimensional echocardiogram Orientation:Three dimensional parasternal short axis image Description: This 3D echo videoclip in the parasternal short-axis orientation is from a different patient with a subaortic fibrous ring (SAR). Note the striking similarity between the gross specimen above and this 3D image. The SAR in the left ventricular outflow tract is seen best between 4 and 9 o'clock in this orientation. The aortic valve leaflets are not seen in this view. The atrial septum is seen at approximately 7 o'clock and the septal leaflet of the tricuspid valve is seen opening and closing at approximately 10 o'clock.
