Detailed Answer:
Hello!

Welcome on HCM!

Regarding your concern, I would explain that cryoablation seems to be an attractive option and quite comparable with radiofrequency ablation (in terms of efficacy and safety) in treatment of atrial and ventricular arrhythmias.

This is achieved by eradicating the arrhythmogenic focuses inside the myocardium (cardiac muscle).


But, returning to your exact question, it is necessary to emphasize the exact profile of cardiac arrhythmia to whom the ablation is indicated.

You should know that cardiac arrhythmias are frequently triggered in the settings of a deteriorated cardiac function. And as you are a CRT patient, the left ventricular ejection fraction (LVEF) is supposed to be importantly decreased.

Coming to this point, I would explain that optimizing your actual heart failure therapy could yield beneficial results in regard of decreasing your arrhythmia burden.

A better hemodynamic profile (good conditions of blood circulation throughout the body tissues) would certainly make the arrhythmia less likely to be triggered.

You need to discuss with your doctor on this specific issue.

Now returning to your question again, I would add that nowadays with the introduction of ultra-high density electro-anatomic mapping, cardiac ablation has become more safe and effective.

So, my answer to your question is YES! Cryoablation seems to be a rationale and safe alternative in your case, BUT, this needs to be done by a highly experienced heart team on that matter.

The potential adverse effects are quite comparable with other individual without CRT devices.

You should discuss with your attending EP cardiologist doctor on several issues included in this specific procedure (cryoablation) if other attempts (such as medical optimization of heart failure therapy) has not been shown effective.

Hope to have clarified some of your concern issues!

In case of any further uncertainties, feel free to ask me again.

Wishing you a Happy New Year!

Kind regards,

Dr. Iliri
