Key result
Low-power epicardial radiofrequency ablation successfully treats PJRT-induced cardiomyopathy in a 3-month-old infant.
Why the study?
Epicardial ablation of PJRT in infants, especially with lesions placed in a coronary sinus diverticulum, is rarely reported and clinical experience is limited.
Can low-power radiofrequency ablation safely and successfully treat persistent junctional reciprocating tachycardia (PJRT)-induced cardiomyopathy in a 3-month-old infant?
Case Report (n=1)
Can low-power radiofrequency ablation safely and successfully treat persistent junctional reciprocating tachycardia (PJRT)-induced cardiomyopathy in a 3-month-old infant?
Low-power epicardial radiofrequency ablation in the coronary sinus can safely and successfully treat PJRT-induced cardiomyopathy in very young infants.
May offer a feasible option in refractory infantile PJRT cardiomyopathy; hypothesis-generating and requires prospective validation.
A 3-month-old infant who developed persistent junctional reciprocating tachycardia (PJRT)–induced cardiomyopathy that was successfully treated with radiofrequency ablation. To our knowledge this is the youngest reported patient with a successful epicardial lesion placed in a diverticulum off the coronary sinus and also the first report of a PJRT connection located at an epicardial site distinct from the mitral and tricuspid valve annulus. We use this case to highlight how low-power lesions in the coronary sinus in the youngest of patients can achieve results safely. (Level of Difficulty: Advanced.)

McKenzie et al. (2021) conducted a case report in Persistent junctional reciprocating tachycardia (PJRT)-induced cardiomyopathy (n=1). Radiofrequency ablation (epicardial lesion in the coronary sinus) was evaluated on Successful treatment of PJRT. Radiofrequency ablation using low-power epicardial lesions in the coronary sinus successfully treated persistent junctional reciprocating tachycardia-induced cardiomyopathy in a 3-month-old infant.
