ABSTRACT
BACKGROUND:
The incidence of pericardial effusion (PE) during radiofrequency catheter ablation (CA) for atrial fibrillation is approximately 1%. PE is a major complication during CA, but there has been limited literature about the perforation site responsible.OBJECTIVE:
This study aimed to retrospectively investigate the characteristics of the procedure and the patients in whom PE developed during CA.METHODS:
Of 1363 consecutive patients who underwent catheter ablation from January 2015 to June 2019 in Kyorin University Hospital, we reviewed patients who developed PE during CA.RESULTS:
PE during CA occurred in 18 (1.32%) patients (median age, 71 [interquartile range (IQR) 65-77] years, 7 women). The median body mass index was 24 (IQR 20-27). Target arrhythmias for CA of patients with PE include atrial fibrillation (AF) (n = 13, 72%), premature ventricular contraction (n = 2, 11%), ventricular tachycardia (n = 1, 6%), atrial flutter (n = 1, 6%), and orthodromic reciprocating tachycardia (n = 1, 6%). Seventeen patients required pericardiocentesis, resulting in 300 (IQR 192.5-475) mL of drainage. Two patients required emergency surgical repair, and 1 died from aortic dissection. Based on the gas analysis, the drained blood was of venous origin in 47% of the total events and 54% of AF ablation.CONCLUSION:
PE caused by a diagnostic catheter in the right heart is not uncommon, even in AF ablation.
