Cardiac Ablation Treatment for Arrhythmias: Need and Risks Associated

Tuesday, 29 Apr 2014 11:57 PM

Heart diseases are of many types and arrhythmias are some of them. Arrhythmias are disorders of the heart, where there is disturbed heart rhythm. Many types of arrhythmias are described in medical science. Some of them are supraventricular tachycardia, Wolff-Parkinson—White syndrome, atrial fibrillation, and idiopathic ventricular tachycardia.

People generally recognize arrhythmias by missed heartbeats or irregular pulse. Many factors including diabetes, heart attack, electrical shock, blocked arteries, congenital defects, etc. may cause arrhythmias. Arrhythmias can be mild, manageable with medicines, and risky, requiring emergency intervention. Arrhythmias can be risky for health as certain arrhythmias may increase risks of stroke and heart failure.
 
Often, medicines are prescribed for arrhythmias, but in some cases, cardiac ablation is necessary. People who face side effects of medicines and are prone to health risks due to arrhythmias are advised cardiac ablation therapy.
 
Cardiac ablation therapy means scarring the point of origin of arrhythmias. It is called cardiac ablation treatment as well. Cardiac ablation is usually done with long catheters which are inserted up to the heart and the structure of origin of arrhythmia is destroyed. In some circumstances, open heart surgery is required to commence cardiac ablation treatment. Cardiac ablation treatment is of many types, such as cryogenic ablation, radiofrequency ablation, cardiac catheter ablation, and laser ablation.

Cardiac ablation therapy may be a slightly risky procedure as it involves cardiac catheterization procedure.
 
Bleeding from the site of catheter may be a risky event. Inserting the cardiac catheter into the vessel may be risky as it can damage them. It is therefore advised to be conducted under ultrasonic guidance.
 
Blood clots produced during the procedure are risky for the heart and brain and can be a source of heart attack and stroke.
 
Sometimes destroying the structure of origin of arrhythmias becomes risky as it can disturb the normal rhythm and requires a pacemaker to start the heartbeats again. People may need medicines again to balance the rhythm.
 
Another risky condition encountered sometimes with ablation is phrenic nerve paralysis. It may be risky to inject the dye during cardiac ablation since it may evoke allergic response and damage the kidneys. It is always recommended to check for dye allergy before inserting it into cardiac catheter.
 
Advanced age, associated diabetes, and kidney diseases also make cardiac ablation therapy a risky affair. Doctors should thoroughly weigh the risks and benefits of ablation before recommending it to patients.

Arrhythmias are types of heart diseases characterized by irregular heartbeat. They can range from mild to risky depending upon the type of the disease. Medicines and cardiac ablation are indicated to get rid of arrhythmias.
