Yes, I was recently diagnosed with mild left ventricle dysfunction. My ejection fraction was 45% and my heart was enlarged. I attributed this to the ASD (atrial septal defect) that I had repaired at age 16. However, when I took my two boys (age 9 and 12) in to the cardiologist they both had low ejection fractions too. My youngest also had a small ASD and his ejection fraction was 48%. My youngest is awaiting a genetic work up. We are going to the genetic in June. We are new to all this. We thank Dr. Diane for her study we would have never put the pieces together without her.
