Best Pediatric Cardiologist Mississauga Near Me

4worldlovers:
Dr. Freud is the Director of Fetal Cardiology and an Associate Professor of Paediatrics. She graduated from Harvard Medical School, completed cardiology training at Lurie Children’s Hospital of Chicago, and advanced cardiac imaging and research fellowships at Boston Children’s Hospital.

She was previously on the faculty at Columbia University Medical Center where she began exploring novel applications for fetal cardiac therapy and helped develop a fetal cardiac intervention program. Her research has centered on understanding the natural history of cardiac disease in utero and investigating both percutaneous and pharmacologic therapies to improve outcomes by the time of birth. In addition, she is working to understand the impact of a prenatal diagnosis of copy number variants and genetic syndromes, particularly 22q11.2 microdeletion syndrome, on perinatal outcome.

Dr. Freud studies how heart disease progresses in the womb. Heart disease may be due to abnormal development of the structure or function of the heart, or may be due to other conditions affecting the unborn baby. The information gleaned from her research is not only important for counseling expectant parents, but also to identify potential targets for therapy to optimize the baby’s outcome by the time of birth and beyond.

In addition, she investigates the impact of a prenatal genetic diagnosis or genetic variants of the heart disease on outcome. She is particularly interested in unborn babies with 22q11.2 microdeletion syndrome, the majority of whom have congenital heart disease.
