">MAZE PROCEDURE
maze procedure cryoablation atrial flutter
The objectives of the Maze procedure are 3-fold: (1) to cure atrial
fibrillation, (2) to restore atrioventricular synchrony, and (3) to restore both right and left atrial transport function.
Heye Zhao, a Texas resident now in his 60’s, probably contracted mitral
valve disease in his early 20’s 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.
“With SurgiFrost, which is easy to handle and achieves desired
temperatures very rapidly, I am consistently able to perform a full
Cryo - Maze procedure with deep, efficacious lesions on both the left and
right side of the heart,” said Dr. Mack. “This enhanced comfort level
in producing these lesions, particularly closer to critical structures
such as the coronary sinus and mitral valve annulus, is contributing to
excellent long-term patient outcomes.
SURGIFROST – AN EFFECTIVE CHOICE
- Cryoablation has been used effectively as part of the maze procedure for atrial fibrillation (AF) treatment6
- “Most of the incisions originally performed as a part of the Maze-III procedure have been replaced by cryolesions.”3
- Short ablation times
- Transmural linear lesions can be produced in an open heart, or on a closed beating heart
Our laboratory experience with the left atrial isolation procedure and
with the experimental maze procedure confirmed that the only sure way
to interrupt conduction along the coronary sinus is to cryoablate it.
