A client has been admitted repeatedly in the past year for episodes of atrial flutter which the cardiologist believes are caused by an area of conduction in the atria other than the SA node. Medications have not improved the condition. Which procedure should the nurse anticipate will be performed?
Heart transplantation
Defibrillation
Coronary artery stent placement
Radiofrequency catheter ablation
The Correct Answer is D
A. Heart transplantation is not indicated for atrial flutter; it is reserved for end-stage heart failure or severe cardiac conditions that cannot be managed by other means.
B. Defibrillation is used in emergency situations for life-threatening arrhythmias like ventricular fibrillation, not for atrial flutter.
C. Coronary artery stent placement is used to open blocked coronary arteries, not to treat arrhythmias.
D. Radiofrequency catheter ablation targets and destroys the abnormal conduction pathways causing atrial flutter, providing a more permanent solution when medications are ineffective.
