"Unlocking the secrets of heart disease in children both at the bench and at the bedside, and then developing new diagnostic and treatment approaches is most rewarding. In that way, my work extends not only to the children I personally treat but also to those cared for by other physicians."

  • Michael A. Portman, MD, is director of research in the Division of Cardiology at Seattle Children’s Hospital and professor in the Department of Pediatrics at the University of Washington School of Medicine. He is attending physician at Seattle Children’s Heart Center and the Cardiology Clinic at Providence Everett Medical Center.

    Portman’s research activities include pharmacological clinical trials, basic science research projects focused on cardiac metabolism in animal models and mentoring future clinical researchers. He is an editorial board member of the American Journal of Physiology — Heart and Circulatory Physiology and co-investigator for a grant on cardiovascular research training.

      We moved to live in 2003 to Seattle From Mexico and We immediately Contacted a Dr. to follow My son history of KD , he has KD at 2 years old . And we still follow his investigation and watching that He has been doing amaizing discoveries. My son is 21 know and He still avoiding the milk and he was raised with soy milk and know we understand a lot of KD thanks Dr. for you amaizing Job.

      Dr.Portman, and Dr. Jeremy are the most amazing specialist. They deserve life's path 5o peace , comfort, and compassion. My5 the child was diagnosed with Kawasaki disease at 4.5 months.Its much thankfulness too them that my baby girl is here with us today, healthy.They a4e worth a million

      We absolutely love Dr. Portman. My son was diagnosed, in September, with an unusual case of Kawasaki Disease. I had little answers, and the stress and fear continued to pile up on our family. I remember when we first met Dr. Portman, he came into my son's hospital room, and put an ease to all of our fears. He took the time to answer any questions, and didn't leave until we had an ease and understanding that he was going to do everything possible for our son. He also treated him like a 10 year old boy, who has a bright future ahead of him, instead of another patient in the hospital. His has a huge passion for children in general, but also kids who are diagnosed with this rare disease. I absolutely recommend him to any other family who is seeking a Cardiologist that will take time to make sure you have the absolute best care for your child. He has made such a devastating and scary experience, for our son and family, a little more peaceful with his vast knowledge and sensitivity towards the patient. We love Dr. Portman!

      Dr. Portman is an amazing doctor. He has a Heart of gold. When my brother, Brandon, was 15, He was diagnosed with Hypertrophic Cardiomyopathy also known ad HCM. When I was younger I didn't realize the difference Dr. Portman had made to all our lives.Now That I am older I have realized he gave us all a reason to smile and laugh, no matter how hard the times. My brother has had had 2 open heart surgeries and has a pacemaker. He is okay now. But still has trouble from time to time. His most recent check up. They had told him the left side of his heart is only working at 80%. So this was a set back for us all. I really want to thank Dr. Portman for always explaining things to us in a manner I even knew what was going on back then. And for giving me a chance to grow up beside my brother. I am so happy he was there for the whole family for years. I really owe him my childhood. I don't know what I would have done with out my big brother. So thank you Dr. Portman. I wish you nothing but happiness. Thank you for being such a caring and understanding man!

      DR. Portman is literally the smartest man I have met in real life. I met him when my daughter was 7 days old and he diagnosed her with transposition of the heart. I was 23 years old and my baby was broken. I was devastated . He treated her with kindness and caring. He was very good at explaining every detail of her treatment and what exactly was going on with her. He was there through Surgery and always goes above and beyond. His decisions saved her life. My daughter will be 19 in October and is still going strong thanks to his knowledge and expertise . She is going to college in the Fall and chose a college in Seattle so we could have his knowledge and care right down the road in case anything happens. He is an honorary member of my family and we all love him for what he has done for us.

Research Description

We also perform research in Kawasaki Disease, which is an inflammatory syndrome attacking coronary arteries in children. Our work includes drug studies in animal models, and pharmacogenomic studies in patients. We are also performing clincial trials in patients.

We study cardiac metabolism and the impact of changing substrate utilization on the heart during development and during pathological states such as heart failure and cardiopulmonary bypass. Thyroid regulation of metabolism is a primary interest. Work is translational and progresses from basic benchtop studies to mice to large animals to the bedside.

Research Focus Area
