An aortoplasty using a gusset is a surgical procedure specifically designed to address supravalvular stenosis, a congenital condition characterized by the narrowing of the ascending aorta just above the sinuses of Valsalva. This condition leads to an obstruction in the left ventricular outflow tract, which can significantly impact cardiac function. The procedure involves a series of carefully orchestrated steps to ensure the successful widening of the affected area. The surgical approach typically begins with a median sternotomy, which provides access to the heart and aorta. Following this, cardiopulmonary bypass is initiated to maintain circulation and oxygenation during the surgery. A distinctive inverted Y-shaped incision is made in the ascending aorta, extending across the supravalvular ring and into the noncoronary and right sinuses of Valsalva, allowing for direct access to the stenotic region. To effectively enlarge the narrowed area, a synthetic patch, referred to as a gusset, is placed over the incision. This patch is sutured securely to the aorta, thereby increasing the diameter of the stenotic region and facilitating improved blood flow. After the patch placement, cardiopulmonary bypass is discontinued, and the chest incisions are closed, marking the completion of the procedure.
