Fetal Dilated Cardiomyopathy
Thank you to Dr Jorge Faerron (Twitter: @cardiopedhnn) for pointing out this great article that is available open access.
Case of severe fetal dilated cardiomyopathy
Zoom on the mitral and tricuspid valve which are seen to open and close. The flap of the foramen ovale is seen also going toward both sides of the septum, possibly indicating a bidrectional flow. The AV valves open only shortly, possibly indicating poor filling. The heart is dilated. There is severe systolic dysfunction.
Dilated cardiomyopathy. THe apex of the RV looks trabeculated from the distension.
Apical views outlining the architecture of the tricuspid and mitral valve. One may appreciate also in the last panel, the pulmonary valve which is seen opening and closing, indicating that there is forward flow.
Colour box indicates that there is filling through the tricuspid valve and some regurgitation. Colour indicates that there is flow going towards the LVOT. One may also appreciate the mitral insufficiency.
PFO indicates that there is flow occasionally left to right, indicating high LA pressure from likely the severe LV dysfunction.
Arch does not look obstructed
Tricuspid insufficiency
Aortic valve opens and closes, indicating that there is forward flow.
Dilated heart relative to the chest
TAPSE indicates reduced RV function
Some degree of Aortic Valve hypoplasia
Both atrio-ventricular valves are open
