Cardiac cryoablation

Description cryoablation heart

Krioabljacija uses the effect of extremely low temperatures for cell disruption. Cardiac cryoablation is used to destroy abnormal cells of the heart.

Causes cryoablation of cardiac

Процедура проводится чтобы “отключить” клетки сердца, which create irregular heartbeat (arrhythmia). After the procedure, normal heart rhythm should be restored.

Possible complications after cardiac cryoablation

Complications are rare, but no procedure does not guarantee the absence of risk. Before, how to perform the procedure, you need to know about possible complications, which may include:

• Bleeding;
• Infection;
• Pain at the site of catheter insertion;
• Blood clots;

• Abnormal heart rhythm;
• Heart attack;

Factors, that may increase the risk of complications include:

• Smoking

The risk level can be associated with a particular type of arrhythmia.

How is cryoablation?

Preparation for the procedure

Doctor, probably, perform these steps::

• Electrophysiological study (EFI heart), to pinpoint the location of the abnormal rhythms;

The doctor is the source of the arrhythmia. This will be done by determining the place of arrhythmia special catheter tip. Once the problem areas will be found, it is cooled down with the tip of the catheter. If the place is a source of arrhythmia found correct, the problem goes away. If the place chosen by mistake, the cold end of the catheter is removed and the tissue will not have any injuries.

When the location of the arrhythmia is detected properly, end of the catheter is cooled to -70 ° C. It numbs the heart tissue and eliminate the arrhythmia. Search procedure is repeated, until you have removed all sources of arrhythmia.

The average hospital stay

Most patients have to stay in hospital overnight for observation. The doctor can extend the stay, If there are complications.

Caring for the patient after cryoablation heart

Care in a hospital

• The catheter insertion site may be bruised and sore;
• If the catheter was inserted into the groin area need some time to lay in bed with straight legs;
• If the catheter was introduced in the wrist or arm, you do not need to stay in bed;

• You can return to normal activities, allowed walking or climbing stairs. Refrain from heavy physical exertion, or for 24 hours. In most cases, you can return to normal activity within a few days;
• Timely need to pay visits to the doctor. Catheter insertion site should be checked for complications.

In this procedure, an extremely high success rate and low risk of complications. But:

• При наличии фибрилляции предсердий или желудочковой тахикардии, perhaps, will have to continue antiarrhythmic therapy;
• After cryoablation of the AV node, you need a pacemaker.

After returning home, you need to see a doctor, If the following symptoms:
