Catheter-Based Ablation Process Video

Dr. Shukla describes a process known as Catheter-Based Ablation (which is the idea that by ablating, or destroying, abnormal tissue areas in the heart, its electrical system can be repaired).

What Is Catheter-Based Ablation? The catheter-based ablation has been around for approximately 20 years and very popularly around for 20 years. It was originally used for very simple SVT ablations. The cure rates got very good in a very short period of time and they became a very safe way of actually curing arrhythmias, not masking them with medications. The complication rate with these types of procedures are exceedingly low. They’re minimally invasive surgeries that what we do is we pass up spaghetti-like catheters through the veins of the legs generally; occasionally we use the veins under the collar bone or in the neck to pass the special catheter but what we do is we put catheters that have the ability to record the electrical activity in the heart and generate the electrical impulses. We place these catheters in strategic locations that we know where the normal electricity should be going to. We then subsequently place a special catheter generally referred to as the ablation or "mapping" catheter to inside the heart and we could provoke these circuits while we’re in the procedure. We use that special catheter to map around the heart chamber and localize it through a specific spot and then we could deliver some sort of energy source that the most commonly used is radio frequency energy. We deliver energy through that catheter and we’re able to actually—that translates the heat at the tip and then actually burns a very small area in the heart with very little collateral damage. So, we’re able to actually destroy that circuit in the heart and thereby cure these arrhythmias.
