New therapeutic option for junctional ectopic tachycardia in infants following congenital heart surgery: ivabradine, a case report

Abstract

Junctional ectopic tachycardia (JET) is the most common tachyarrhythmia that appears mostly during the immediate postoperative period of congenital heart surgery. Patients who develop JET have increased mortality and morbidity. Despite the availability of different antiarrhythmic treatments, management of JET is still challenging. We report a case of reversing of malignant JET following congenital heart surgery with the use of oral Ivabradine, after the failure of all the others treatment options of JET. Ivabradine is a drug used in adult practice to lower heart rate in heart failure and angina. Our case report may provide hope that Ivabradine may be a new therapeutic option for JET in infants following congenital heart surgery.
