Abstract
Purpose
Here, we describe the efficiency of interventional electrophysiology therapy in a critically ill patient with heart failure because of incessant AV node reentrant tachycardia after surgical port implantation.
Methods
Electrophysiology diagnostic and radio frequency ablation were utilized in the study.
Result
We presented a 78-year-old patient with colorectal cancer, surgical port implantation, and progressive heart failure due to an incessant AV node reentrant tachycardia (AVNRT). This rhythm disturbance was refractory to any conventional pharmaceutical treatment. The electrophysiology diagnostic obtained an AVNRT. During fluoroscopy, an oversized port catheter with a loop touching the tricuspid valve annulus was discovered. This port catheter was responsible for premature beats, which induced incessant AVNRT. A manual reposition of the port edge and additional AV node slow pathway modification terminated further tachycardia.
Conclusion
Electrophysiology diagnostic and radiofrequency ablation procedures are promising techniques also in critically ill patients with hemodynamic compromising supraventricular tachycardia.
