UHL ANOMALY Figure 17-13 UHL ANOMALY The ventricular wall is devoid of muscle, showing endocardium (black arrow) directly opposed to epicardial fat. This complete lack of muscle in the wall is different than the pathology seen in arrhythmogenic cardiomyopathy.

TAUSSIG-BING ANOMALY: ARTERIAL SWITCH OPERATION Figure 37-42 TAUSSIG-BING ANOMALY: ARTERIAL SWITCH OPERATION Muscular subaortic (neo-subpulmonary) stenosis (yellow arrows) was severe, dynamic, and fatal postoperatively, in an infant. The ventricular septal defect patch (white arrow) is intact. More about this image found in TAUSSIG-BING ANOMALY: ARTERIAL SWITCH OPERATION Muscular subaortic (neo-su...

EBSTEIN ANOMALY Figure 39-1 EBSTEIN ANOMALY The septal and posterior tricuspid leaflets are displaced downward, the right ventricle is divided into atrialized and functional portions, and the right-sided chambers are dilated.

EBSTEIN ANOMALY: DOWNWARD DISPLACEMENT Figure 39-5 EBSTEIN ANOMALY: DOWNWARD DISPLACEMENT Between the true annulus (white arrow) and the functional annulus (yellow arrow), the posterior leaflet is anchored to the underlying free wall by numerous short myocardial stumps rather than by tendinous More about this image found in EBSTEIN ANOMALY: DOWNWARD DISPLACEMENT Between the true annulus (white arr...

EBSTEIN ANOMALY: DOWNWARD DISPLACEMENT Figure 39-6 EBSTEIN ANOMALY: DOWNWARD DISPLACEMENT From the hinge-point (dashed line), the distorted septal and posterior leaflets have little mobility due to multiple abnormal attachments to the free wall, in a middle-aged adult. An acute infarction More about this image found in EBSTEIN ANOMALY: DOWNWARD DISPLACEMENT From the hinge-point (dashed line),...
