A patient with type IV unroofed coronary sinus presenting with wide QRS Tachycardia

Abstract

Unroofed coronary sinus (UCS) is a congenital heart disease characterized by defects in the formation of the coronary sinus. UCS usually manifests as dyspnea on effort, fatigue, or palpitation. However, here, we present a case of a 53-year-old female whose presentation was wide QRS tachycardia. In this interesting case, we describe the role of various echocardiographic modalities used to reach its elusive diagnosis.
