[Paroxysmal Supraventricular tachycardia/Complications] |
Complications related to catheter ablation for paroxysmal Supraventricular tachycardia include those described below.
Because we have had few complications at our institution (we had no complication listed below except puncture site hemorrhage in recent 5 years), we have listed the general incidence rates for the known complications.
|
1) Cerebral infarction: 0.2% |
When a catheter needs to be inserted into the left ventricle or the left atrium, blood clots on the end of a catheter can flow into and clog a vessel that nourishes the brain, which can result in cerebral infarction. We have not observed this complication at our institution. |
2) Complete atrioventricular block: 1% |
When a slow conduction pathway needs to be cauterized because of atrioventricular nodal reentry tachycardia, for example, implantation of a heart pacer is required. Otherwise, heat may be transmitted to the excitation conduction pathway and cause a complete atrioventricular block and then bradycardia. We have not observed this complication at our institution. |
3) Cardiac tamponade: 0.6% |
Cauterization can weaken the cardiac muscle and cause blood to leak outside the heart and accumulate. This can result in a lower blood pressure, bradycardia, and ultimately a shock state. If this occurs, another catheter is inserted at the site to extract the blood.
|
4) Puncture site hemorrhage |
Internal bleeding can occur at the site of catheter insertion and result in a restraining hemorrhage, which usually. heals spontaneously. |
