Modified Bentall-De Bono Procedure Using a Composite Graft With an Aortic Mechanical Valve
This patient underwent repair of Tetralogy of Fallot and more recently had enlargement of his aortic root with moderate-to-severe aortic insufficiency. Worsening of left ventricular function with an ejection fraction of 40% was observed on follow-up echocardiograms, and moderate-to-severe aortic valve regurgitation was also noted. A computed tomography and MRI were performed to assess the ascending aorta and aortic root, as well as left and right ventricular function. The left ventricular function was moderately depressed and the aortic root was measured at 5.7 cm. A modified Bentall-De Bono procedure was performed, using a composite graft with an aortic mechanical valve. The patient recovered well and was discharged after the sixth postoperative day.
