Hello, I recently had an echo done because I have been feeling out of breath lately. No one called me to follow up yet and i don't know what this all means? Should I be concerned? I'm 32. The results were: Impression Summary Ejection Fraction = 45-50%. Left ventricular systolic function is mildly reduced. A variety of Doppler measurements indicate impaired left ventricular relaxation, which is associated with grade I/IV or mild diastolic dysfunction. The discontinuity of the interatrial septum is suggestive of an atrial septal defect.
