One-Stage Surgical Management of Adult Native Coarctation and Severe Aortic Stenosis: A Case Report

The coarctation of the aorta is a congenital anomaly characterized by a local narrowing of the aortic lumen localized near the ductus arteriosus. Typically diagnosed in childhood, but it can remain until symptoms become evident. This aortic anomaly can also coexist with aortic valve stenosis. In our case report, we present a 46-year-old male with chest pain, dyspnea, and a significant blood pressure gradient between upper and lower extremities. Diagnostic examination included transthoracic echocardiography and computerized tomography. This diagnostic imaging showed narrowing of the aortic lumen with a residual lumen dimension of 3 mm and severe aortic stenosis. The patient underwent a complex surgical procedure, replacement of the aortic valve and reconstruction of the aorta. An extra-anatomic ascending-to-descending aortic bypass was constructed using a 20 mm Dacron graft, combined with mechanical aortic valve replacement. The operation was performed through median sternotomy with two arterial canula in the femoral artery and in the aorta, and one venous canula in the right atrium. Two canulae are placed for the safe performance of cardiopulmonary bypass. The patient was discharged at home without complication. This case highlights that a single surgical procedure may represent a definitive treatment of a complex problem with good short-term results.
