Cardiac Ablation - Health Article

Cardiac Ablation

what is ablation ?

Ablation is the burning away of the cells in the heart wall to be treated. An abnormality in the cardiac conduction system Such a deviation may cause cardiac arrhythmia.

An ablation is a procedure which sometimes forms part of an electrophysiological study. The burning off of the tissue is done with a small electrode on the tip of a catheter which is placed in the heart. Through the blood vessels Who ablation undergoes only keeps a wound in the groin to left.

Ablation is a relatively new treatment of cardiac arrhythmias. The treatment in most cases, success is increasingly used.

Abnormality in the electrical conduction

The heart is turned to contract by an electrical stimulus that rapidly moves through the heart muscle in a domino effect. The cardiac conduction system controls the route and the speed of the electric stimulus. In a healthy heart, the electrical stimulus in the sinus node in the right atrium and then move into the muscle cells of the rooms, after a short stop at the central AV node. Themselves through the atrium walls begins The cardiac conduction system functioning as well as the electrical stimulus follows an alternative route. Or not the heart muscle in the right order and speed together. By an ablation of the alternative route may be shut down.

Scar tissue

In an ablation dies a small group of cells by heating off (ablation is derived from retinal detachment, Latin for 'removal'). At the site of the burn scar tissue that is no longer passes through the electrical stimulus is created. By ablation, the alternative route for the electrical stimulus being blocked.

Radio frequency ablation

The idea of ​​ablation is not new in itself, but the technique does. Burning away of tissue in the heart was able to initially only on a relatively inaccurate manner. A breakthrough was the technique with radio-frequency current that was introduced in 1987.

For those interested: it is alternating current with a frequency of about 500 kilometers Hertz. The tip of the catheter is heated to about 50 degrees. With this technique, the cardiologist can keep on working. The modern technique of ablation is fully called radiofrequency catheter ablation (RFCA).

Electrophysiologic study

An ablation is sometimes part of the electrophysiological research. Sometimes an ablation procedure not performed during the first, but at a later time. Who is undergoing an ablation is an operating table. Via the blood vessels are placed in different places in the heart catheters. First with the catheters measured where in the heart muscle itself is exactly the alternative route. As it is known, the cardiologist can start with the actual ablation.

The burning away of the cells does not happen at once, but in a number of successive steps. The procedure can sometimes take hours. After the ablation is being tested or the heart rhythm disorder is gone. This can be done by to administer medications that induce the cardiac dysrhythmia and see what happens.

Probability of success is high

The chances of success in an ablation is quite large. Complications are rare. Very occasionally the cardiac conduction system is damaged and needs a pacemaker implanted.
