What does maze stand for in cardiac surgery?
37.33. The Cox maze procedure, also known as maze procedure, is a type of heart surgery for atrial fibrillation. “Maze” refers to the series of incisions arranged in a maze-like pattern in the atria. Today, various methods of minimally invasive maze procedures, collectively named minimaze procedures, are used.
Is the maze open-heart?
The surgical ablation version of the maze procedure is much faster than Cox Maze III and is considered very effective. As an open-chest procedure, it is usually performed on patients needing open-heart surgery for other issues, such as valve replacement or repair or coronary artery bypass (CABG).
What does the maze procedure do?
The maze procedure is the surgical ablation approach with the greatest long-term success in treating atrial fibrillation. The maze procedure includes creation of lines of conduction block (scar tissue) that block the abnormal impulses that cause atrial fibrillation, enabling restoration of normal sinus rhythm.
Why is it called a Maze procedure?
Some surgeons use a combination of techniques to make the incisions. The incisions are made in a certain pattern, like a maze, that will direct the heart’s electrical impulses straight to the heart’s lower chambers. Maze surgery works because after the heart heals, scar tissue forms.
What does acronym maze mean?
Definition. Options. Rating. MAZE. Minnesota Association for Zombie Enthusiasts.
How long does the Maze procedure last?
Total time in the operating room is usually about two to three hours. The Maze procedure itself takes about an hour. The remainder of the time is spent safely engaging and disengaging from bypass, opening and closing the chest, and inserting the necessary pressure monitoring lines.
How does the AtriClip work?
The AtriClip, which is applied to the outside surface of the left atrial appendage, permanently closes the left atrial appendage at its base, preventing blood from entering the pouch. This procedure is performed by a cardiac surgeon using minimally invasive surgical techniques.
Is maze surgery open-heart surgery?
Traditionally, the Maze procedure is done as part of an open-heart surgery assisted with a heart-lung machine (cardiopulmonary bypass). Instead of making cuts, doctors can use radiofrequency energy or freeze the tissue to disrupt the abnormal signals.
How long does Maze procedure take?
The surgery takes about 3 hours. For patients who have AF along with other heart problems like coronary artery disease or valve disease, the surgeon may combine Maze surgery with other operations that will correct both problems.
Does Maze procedure cure AFib?
Surgical maze procedures have a high success rate, with from 70% to 95% of people being free of atrial fibrillation long term after the procedure. Some people may still need medications to help control their irregular heart rhythm after the procedure.
Why is it called maze?
The word “maze” dates from the 13th century and comes from the Middle English word mæs, denoting delirium or delusion. The word “labyrinth” may date as far back as the 14th century, and derives from the Latin labyrinthus and the Greek labýrinthos, or, a building with intricate passages.
What is a cardiac maze procedure?
James Cox , MD, and associates developed the “maze” or “Cox maze” procedure, an “open-heart” cardiac surgery procedure intended to eliminate atrial fibrillation, and performed the first one in 1987. “Maze” refers to the series of incisions arranged in a maze-like pattern in the atria.
What is maze heart procedure?
A maze procedure is a surgery used to control atrial fibrillation, or “a-fib,” a heart condition where the heart rhythm is irregular. If it can’t be controlled by medication or other treatments, a maze procedure may be an appropriate treatment. It gets this name from the linear scars left on the heart’s chambers post-surgery, like a maze.
What is a medical maze procedure?
The maze procedure is a type of heart surgery used to fix a condition that involves an irregular heartbeat, known as atrial fibrillation . The surgical procedure involves creating scar tissue at strategic locations around the heart.
What is a heart maze?
Maze is a surgical procedure used to treat atrial fibrillation. A doctor creates a pattern of scar tissue (the maze) in the upper chambers of the heart by applying heat (radiofrequency energy) or cold (cryoablation).
