Abstract Objective To evaluate the efficacy and safety of radiofrequency catheter ablation (RFCA) in very old patients with paroxysmal supraventricular tachycardia (PSVT). Methods 11 patients (over 80 years of age) with PSVT underwent RFCA. Results RFCA was successful in all patients. 2 cases underwent coronary angiography before RFCA.A long sheath or contralateral iliac artery was chosen in 4 cases for iliac artery tortuosity. Heart failure occurred in one case, atrial fibrillation and atrial tachycardia in 5 cases during the procedure. RFCA was performed by transseptal approach in one case for aortic valve stenosis. First degree atrioventricular block occurred in 2 cases and second degree in one case during delivery of energy. Hematoma at puncture site occurred in one case. There was no serious complication and recurrence during 24-month follow-up. Conclusion RFCA is effective and safe for very old patients with PSVT, but individual strategy is needed.
