Palliative Senning Procedure: Management of dTGA with VSD and PVOD in an Adolescent

Patients with D-TGA with atrial level mixing of systemic and pulmonary blood, the morphological left ventricle supports the low pressure pulmonary circulation and regresses in mass and volume as time passes. The LV once regressed is unable to support the high pressure systemic circulation after ASO. These patients are candidates for early ASO, preferably within 3 weeks of life. As age progresses, the scope of these surgical procedures skews and an atrial switch remains the only option to improve quality of life. In Atrial switch, the pulmonary and systemic circulation is returned into an “in series” circulation and cyanosis is obliterated.
