Overview
Aortico-left ventricular tunnel is a rare congenital anomaly characterized by a direct communication between the ascending aorta and the left ventricle, potentially leading to hemodynamic disturbances and valvular insufficiency if untreated. 2Diagnosis
Echocardiography: Essential for diagnosis, typically using two-dimensional imaging to visualize the anomalous connection 2.
Anatomical assessment: Detailed echocardiographic evaluation to determine the size and extent of the tunnel 2.Management
Surgical repair: Open-patch aortoplasty technique recommended, especially in neonates, to prevent valvular insufficiency 2.
Transcatheter closure: An emerging alternative for certain cases, particularly when surgical intervention is deemed high-risk 1.Special Populations
Neonates: Early surgical intervention using open-patch aortoplasty is feasible and recommended to avoid complications associated with older age 2.
Adults: Limited data; transcatheter closure may be considered in selected cases, though surgical approaches remain predominant 1.Key Recommendations
Perform early surgical repair with open-patch aortoplasty in neonates to prevent valvular insufficiency (Evidence: Strong 2).
Consider transcatheter closure as a viable alternative in carefully selected adult patients (Evidence: Weak 1).
Utilize echocardiography for definitive diagnosis and preoperative planning (Evidence: Moderate 2).References
