Patient Review of Dr. S. Chris Malaisrie

"Nine weeks after surgery, I've come so far. I'm already walking 2 miles and back to my daily life. God, bless my surgeon Dr. S. Chris Malaisrie and the Northwestern team!"

-- Janis Kielbas, heart valve surgery patient

"I was diagnosed with an enlarging aortic aneurysm in October 2024 through my monitoring echocardiogram. I have been having them to monitor my slight regurgitation of my aortic valve from a previous open heart surgery decades earlier.

After doing my own research mostly on HeartValveSurgery.com, I became familiar with Dr. Malaisrie. Being a former Chicagoan, now living in North Carolina, Dr. Malaisrie was my second opinion about my aortic aneurysm. I was very impressed with my virtual consultation with him. He was exactly who I thought he was after seeing several videos of him at HeartValveSurgery.com.

After he assured me he could repair my bicuspid valve I knew he was the surgeon for the job. My local surgeon wanted to replace my valve. In late March of 2025, I had my valve sparing aortic root replacement surgery (David procedure) at Northwestern Memorial Hospital in Chicago. Everything went great!

It was the best decision to fly back to Chicago to have this surgery. The whole experience from the beginning to the end was fantastic. Everyone involved in my care from before surgery, during and after were great! I cannot say enough good things about the people involved in my care.

If you have a complicated heart issue and need surgery, I HIGHLY recommend Dr. Malaisrie and his staff over at Northwestern Medicine. Thank you again Dr. Malaisrie, your staff, and every hospital personnel (doctors, nurses, nurses assistants, technicians, PT’s,OT’s and the hospital maintenance) who took care of me with kindness, compassion and great skill!!!"
