What are the chances of me dying in surgery for svt?

SVT: A procedure for svt is usually done in the cardiac catheterization lab where a cardiologist attempts to ablate the abnormal electrical conduction pathway causing the svt. The risk of death is low, but it is not zero. Surgery may be done for svt but this is often in the context of other heart surgery. Risk of surgery depends upon the procedure involved, which be discussed with your doctor.
