Key result
Oral ivabradine effectively treated postoperative junctional ectopic tachycardia in a young adult after failure of intravenous amiodarone and beta-blockers.
Why the study?
Postoperative junctional ectopic tachycardia can occur after cardiac surgery for congenital heart disease in adulthood and should be recognized by adult physicians as it may require specific therapeutics.
Case Report (n=1)
Oral ivabradine may be an effective treatment for postoperative junctional ectopic tachycardia in adults when standard therapies fail, and JET occurrence might predict late recovery of AV conduction.
May support oral ivabradine trial in refractory adult postoperative JET; hypothesis-generating and leaves open need for prospective data.
-Postoperative JET can occur after cardiac surgery for CHD in adulthood. This life-threatening complication should be known by adult physician community as it may require specific therapeutics.-In this adult case of postoperative JET, oral administration of Ivabradine was the most effective treatment after failure of intravenous Amiodarone and betablocker.-The occurrence of JET in the setting of postoperative CHB could predict future recovery, even late, of AV conduction.-This report presents the timeline of a case of late recovery of AV conduction following cardiac surgery but cannot serve as evidence supporting systematic strategy of prolonged monitoring without permanent pacing.

Moulin et al. (2023) conducted a case report in Postoperative junctional ectopic tachycardia and complete heart block (n=1). Oral Ivabradine vs. Intravenous Amiodarone and betablocker was evaluated on Treatment of postoperative JET and recovery of AV conduction. Oral ivabradine effectively treated postoperative junctional ectopic tachycardia in a young adult after failure of intravenous amiodarone and beta-blockers.
