My mom had german measles in the 1st trimester of her pregnancy in me. is their a possibility that i could get heart diseases from it?

Preg& German measles: Usually if there is going to be problems with exposure to rubella during pregnancy, you would know by now. I doubt you will have any problems with your heart from the exposure.

Yes: The more common results of rubella during first trimester include sensorineural deafness (58%), eye abnormalities—especially retinopathy, cataract and microphthalmia (43%) and congenital heart disease—especially patent ductus arteriosus (50% of patients).
