Background Data on management of maternal arrhythmia among Chinese were limited. Radiofrequency catheter ablation (RFCA) proved to be a reliable treatment choice for sustained tachyarrhythmia but it has rarely been performed during pregnancy due to radiation exposure. Objective To investigate the incidence of idiopathic sustained maternal arrhythmia and the feasibility of RFCA in the pregnant patients without fluoroscopy. Methods From January of 2015 to December of 2018, the medical records on pregnancy-related admissions in Beijing Anzhen Hospital (Beijing, China) were retrospectively analyzed. Patients who had sustained tachyarrhythmia episodes without structural heart disease were identified. Catheter ablation was performed in those with drug resistant and severely frequent tachyarrhythmia under the guidance of electroanatomical mapping system and intracardiac echocardiography catheter (ICE), if appropriate. Results During the study period, 12 584 consecutive pregnant women were admitted for pregnancy-related reasons, 156 (1.2%) of them were identified as sustained maternal tachyarrhythmia. Twenty-eight patients (age 21-37 years) received catheter ablation because the arrhythmias were drug resistant and severely frequent. The RFCA was successfully performed in all patients with zero fluoroscopy after 72.4 +/- 24.7 min. Transseptal puncture was performed in 11 patients under the guidance of ICE. In a median of 37 (interquartile range [IQR]: 34-39) weeks' pregnancy, 28 healthy fetuses were delivered. No cardiac-related adverse event occurred during delivery. During later follow-up, all patients were free of arrhythmia, and all the infants were well developed. Conclusion Sustained maternal tachyarrhythmia is not uncommon in the clinical practice. To those with drug resistant and severely frequent arrhythmia, RFCA with zero fluoroscopy could be safely performed with acceptable efficacy.
