Left ventricular mid-cavity obstruction: A novel cause of duct-dependent systemic circulation in a newborn

Key Points

• To describe a rare congenital anomaly causing significant left ventricular outflow tract obstruction in a neonate.
• Case report of a newborn with accessory mitral valve tissue.
• Assessment of left ventricular outflow tract obstruction.
• Discussion of treatment options, including a hybrid palliative approach.
• Significant left ventricular outflow tract obstruction identified.
• Duct-dependent systemic circulation affecting neck and head vessels observed.
• Hybrid palliative strategy successfully managed clinical symptoms.
