Multiple vascular anomalies in a patient with atrioventricular reentrant tachycardia

Abstract

A 38year-old female patient was admitted to our clinic with the complaint of palpitation in spite of medical treatment. She had a history of hypertension and was using antihypertensive medications including metoprolol and valsartan for two years. Her blood pressure was 140/90mmHg without any significant difference between upper or lower extremities. An electrophysiological study (EPS) was performed because of documented supraventricular tachycardia. Since diagnostic EPS induced an atrioventricular re-entrant tachycardia (AVRT) associated with a concealed left lateral accessory pathway (AP) (Fig. 1A).
