Double-chambered left ventricle: A rare case in a child

Double-chambered left ventricle (DCLV) is an extremely rare congenital heart disease. In this condition, the left ventricle is divided into two chambers by a septum or muscle fiber with abnormal proliferation. A symptomatic boy was diagnosed with DCLV at our hospital. The patient was admitted with the major complaint of 8 years of cardiac murmur, which was discovered through physical examination, and 5 years of palpitations and shortness of breath. He has been followed up without treatment.
