Is cardiac ablation a good treatment for PSVT's, how successful is it, what are the risks, and what are the chances of having to have it done again? Also, can psvt's be caused by something other than a heart arythmia? I am a 50 year old female, and am having weekly episodes of psvt. Today's was cut short I think because I am currently on propranalol. Thanks!

Hi:

As reported in various medical literature, cardiac ablation is considered as being a good treatment, though an obviously extreme treatment of supraventriclar tachycardia (SVT) type of arrhythmia, and has a high success rate of 95-99%.

"What are the risks?"

"What are the chances of having to have it done again?"


Especially with improvements made in older standard radiofrequency energy (heat-based) technology, as well as newer technology cryoenergy/freezing, and high-intensity focused ultrasound, if/when performed by a highly-skilled doctor (IC/EP), via standard endocardial or transthoracic (through-the-chest) epidcardial, and done correctly (no culprit areas, pathways are missed, no normal areas are damaged or disrupted, the culprit tissue is ablated deep enough), a catheter ablation procedure should completely (100%) eliminate one's particular arrhythmia for good.

Noteworthy though, as indicated in medical literature, approximately under 10% of the time, an arrhythmia may recur (at any time) even after what was thought as being an initially successful (single site or multiple sites mapped and treated accordingly) catheter ablation.

This occurs because the abnormal heart cells or electrical pathway responsible for the arrhythmia was damaged, but not 100% therapeutically destroyed by the procedure. As this area heals, the original arrhythmia may reccur. Also, an ablation procedure may/can lead to the occurrence of a totally different type of arrhythmia, sometimes even making pacemaker implantation necessary.

"Also, can PSVT be caused by something other than a heart arrhythmia?"

Yes, as there are various causes or triggers.

As applicable, some individuals have reported, tachyarrhythmias (e.g., tachycardia, supraventricular tachycardia/paroxysmal supraventricular tachycardia) being triggered off by GERD/acid reflux/heartburn, swallowing (food or drink), gas, bloating, belching, burping, or coughing, or after a heavy meal/on a full stomach.

These are known as indirect causes or an "reactive-arrhythmia". This may/can also be a side effect of some foods (which includes additives and preservatives), drinks (e.g. containing alcohol or caffeine) , or drugs (prescription and illegal). As applicable, cigarette smoking may/can also be a trigger.
