Dr. Gang

"Dr. Gang replaced my bicuspid aortic valve and corrected my ascending aortic aneurysm through open heart surgery.

First consultation meeting: Dr. Gang was enthusiastic and outgoing. My wife and I were impressed with his experience, knowledge, and his amazing confidence in his skills. Equally important to me, he had a keen understanding of my existing health/condition and appreciated my objectives to return to competitive cycling. In fact, he thoroughly understood the typical stresses from training and discussed his experience dealing with similar cases. We knew we had the right surgeon.

Surgery experience: My surgery was flawless. I had no complications in the hospital and was released 4 days after surgery. Dr. Gang visited every day to give his assessment.

Post surgery: I’ve had no complications. I was walking every day upon my return home to regain my stamina. Dr. Gang’s staff was AMAZINGLY responsive (often replying within the hour) to every question.

My sternotomy scar is remarkably light - not near as gruesome as I expected. We just had our 5-week checkup with Dr. Gang - he reviewed the surgery with us, shared a picture of my bicuspid valve (cool) and pronounced me healthy - though I still have to allow my sternum to heal!

I can’t recommend Dr. Gang enough. My wife and I are so grateful for his talent and how he treated all aspects of my journey.

I highly recommend Dr. Gang for your surgery. "
