Key result
A 42-year-old female with a restrictive ventricular septal defect presented with recurrent syncope due to supraventricular tachycardia, an uncommon arrhythmia in this condition.
Why the study?
Supraventricular tachycardia is an uncommon occurrence in patients with unoperated ventricular septal defect.
Case Report (n=1)
Highlights an uncommon presentation of supraventricular tachycardia and recurrent syncope in a patient with an unoperated restrictive ventricular septal defect.
Consider SVT in syncope with restrictive VSD; single case leaves open arrhythmia spectrum and management implications.
Ventricular septal defect (VSD) is the most commonly recognized congenital heart disease. The presentation in patients with VSD is variable depending on the size, location, hemodynamic consequences, and complications including bacterial endocarditis, pulmonary hypertension, and cardiac arrhythmias. The most common cardiac arrhythmias in unoperated VSD are premature ventricular contractions (isolated, couplets, and multiform). We present a case of supraventricular tachycardia, an uncommon occurrence, presenting with recurrent syncope in a 42-year-old female with restrictive VSD.

Yerima et al. (2020) conducted a case report in Restrictive ventricular septal defect with supraventricular tachycardia (n=1). Restrictive ventricular septal defect was evaluated. A 42-year-old female with a restrictive ventricular septal defect presented with recurrent syncope due to supraventricular tachycardia, an uncommon arrhythmia in this condition.
