Cardiac catheter ablation is an invasive procedure done to treat abnormal rapid or irregular heart rhythms (arrhythmias). Ablation can be used to treat both supraventricular arrhythmias coming from the upper chambers of the heart (atria) including paroxysmal supraventricular tachycardia (PSVT), atrial flutter, and atrial fibrillation, and ventricular arrhythmias coming from the lower chambers (ventricles).
Different types of catheter ablation for cardiac arrhythmias
“Ablation” refers to localized destruction of tissue, so the area that is being ablated needs to be carefully targeted and the ablation closely controlled. The precise areas targeted for ablation depend on the type of arrhythmia, which sometimes is known before the procedure, but often needs to be clarified or confirmed invasively during the procedure. That being said, not all tachycardias are amenable to ablation or even require treatment, but when non-drug treatment of appropriate tachycardias is appropriate, catheter ablation can be an excellent option.
