Kawada S, Joens C, Chakraborty P, et al. - Researchers assessed how radiofrequency catheter ablation (RFCA) can impact the incidence of direct current cardioversion (DCCV) in adults with congenital heart disease (ACHD). They reviewed 157 ACHD undergoing DCCV from 2011 to 2018 (female n = 76 [48.4%], mean age 37.8 ± 12.5). A median follow-up of 31.8 months (IQR, 16.3-55.1) was performed. There were overall 157 patients, of those, RFCA for atrial tachyarrhythmias (AAs) was received by 102 (65.0%), and 55 (35.0%) were managed without RFCA. Recurrence of AAs in 57 (55.9%) patients who had RFCA as well as undergoing repeat DCCV in 36 (35.2%) patients was reported during follow-up. Repeat cardioversion was needed in 33 (60.0%) of 55 patients without RFCA. Findings showed that among ACHD patients, AAs continued to be common despite RFCA. A marked decrease in the requirement for repeat DCCV was reported in relation to RFCA.
