A successful Cryo Maze procedure has cured this Texas resident of his atrial fibrillation

Heye Zhao, a Texas resident now in his 60s, probably contracted mitral valve disease in his early 20s in his native China. Doctors at Baylor University Medical Center decided that Mr. Zhao's best option was to have a double mechanical valve transplant. SurgiFrost's excellent safety profile allowed Dr. Hebeler to also perform a Maze procedure to prevent the post-surgical incidence of AF.

"Before he had his operation the doctor would not even let him travel. Now he drives a car and walks briskly for an hour every day," says niece Sandy Li. She also reports that he has resumed teaching, tutoring students in mathematics.
