The Rare Fifth Chamber of the Heart: Double-Chambered Left Ventricle.

Double-chambered left ventricle is a rare congenital cardiac anomaly characterized by the division of the left ventricle into two chambers by muscle bands or an abnormal septum. This article presents a case of a patient who complained of chest pain and was incidentally diagnosed with a double-chambered left ventricle. This case underlines the importance of advanced multimodal imaging in identifying rare congenital cardiac anomalies and contributes to the limited clinical literature on double-chambered left ventricle.
