OBJECTIVE
Diagnostic and interventional cardiac catheterization procedures for congenital heart diseases (CHD) are becoming increasingly more popular and arrhythmia is a well-known complication. In this study we evaluated the incidence and causative agents of arrhythmia and the subsequent treatment strategies applied during cardiac catheterization.Patients: We evaluated the catheterization data of all patients who underwent diagnostic cardiac catheterization for CHD between January 2012 and 2018, retrospectively.
RESULTS
A total of 1316 children underwent diagnostic cardiac catheterization due to CHD. Median age and body weight was 18 months (6 days-21 years) and 9.9 kg (2.2–135 kg), respectively. Two major groups of patients had ventricular septal defect (281 patients) and tetralogy of Fallot (257 patients). In 93 (7%) patients, arrhythmia developed during cardiac catheterization. Among them, there were 58 (62%) cases of bradyarrhythmia and 35 (38%) of tachyarrhythmia. Arrhythmia was classified as low, high, or major according to the adverse event severity score; the rates were 2.7%, 4.3%, and 1.2%, respectively. In 36 (39%) patients, there was no need for therapy, whereas 57 (61%) required treatment to eliminate arrhythmia. Treatment modalities included catheter manipulation in 15, pharmacological therapy in 24, and cardioversion in three patients. Eleven patients required cardiopulmonary resuscitation. Temporary pacemaker implantation was required in two patients, while two others underwent permanent pacemaker implantation secondary to catheterization-related arrhythmia. There were no cases of mortality secondary to catheterization-related arrhythmia.
CONCLUSIONS
Diagnostic cardiac catheterization in CHD may result in different cardiac arrhythmias.The proper management of these arrhythmias may reduce morbidity and mortality related to cardiac catheterization.
