215 Patient Reviews for
Dr. McCarthy

"Seven weeks ago, I had mitral valve repair surgery performed by Dr. Patrick McCarthy at Northwestern Medicine. I cannot say enough about Dr. McCarthy and the extraordinary team surrounding him.

From the confidence and expertise Dr. McCarthy brought to my surgery, through my hospitalization and now into recovery, the level of care has been exceptional. What has impressed me just as much as the surgical result is that the care did not end when I left the hospital. Seven weeks later, I still feel that this team is actively involved in my recovery.

I especially want to recognize Janice Knuckey, whose diligence, responsiveness, and follow-through have been remarkable. She was there throughout my hospitalization, at my follow-up appointments, and as recently as this week continues to make sure questions are answered and that my recovery is progressing appropriately. That continuity of care means a tremendous amount to a patient recovering from heart surgery.

Dr. McCarthy is obviously an exceptionally accomplished heart surgeon, but what I experienced was much more than the work of one great surgeon. It is an entire team committed to the patient before, during, and long after surgery.

I am extremely grateful to Dr. McCarthy, Janice Knuckey, and the entire Northwestern cardiac team for the skill, compassion, and continued attention they have given me throughout this experience."

"Dr. McCarthy is a very calm, experienced surgeon. Once I was diagnosed, other surgeons in the area suggested I see Dr. McCarthy for a Mitral Valve Repair. I am just about 10 weeks post-surgery. I feel good with a little bit of pain near the surgical site and a bit of exhaustion at the end of the day.

Each week, I see huge improvements in how I am feeling. I am grateful that Dr. McCarthy repaired my Mitral Valve. I highly recommend him and his team."
