No fixed or reversible perfusion abnormalities detected.
Mild increased RV uptake (arrows with "RV") in the rest and stress study.
The absence of perfusion abnormalities in the setting of markedly increased LV volume strongly suggests LV volume overload condition (CMP ?, valve disease ?).
ECHO
LV dilatation with severe reduction in systolic function
EF=15-20%
Mild mitral regurgitation (1+)
Left atrial enlargement
Comments:
Most likely explanation for the contractile dysfunction is hypertensive CMP, and a less likely theory would be primary CMP.
