Aortitis Syndrome Requiring Redo Bentall Procedure with Coronary Artery Bypass Grafting due to Graft Detachment;Report of a Case]

A 53-year-old woman was referred to us for reoperation of aortic root. Twenty-three years ago, she was diagnosed with aortitis and suffered from annuloaortic ectasia, aortic regurgitation, severe stenosis of left carotid and subclavian arteries and occulusion of the main trunk of left coronary artery. The left coronary system was perfused by collateral arteries from right coronary artery. She had undergone original Bentall procedure( Cooley graft 26 mm+SJM valve 25 mm) with coronary artery bypass grafting (CABG)[saphenous vein graft (SVG)-left anterior descending artery (LAD)]. When she was 52 years old, she suffered from angina on efforts. Computed tomography and catheter angiocardiogram revealed pseudoaneurysm formation due to detachment of right coronary artery button and occulusion of SVG. We underwent redo aortic root replacement (Hemashield graft 26 mm+On-X valve 23 mm) with redo CABG (SVG-LAD). Eight mm graft was interposed between composite valve graft and right coronary button. Postoperative course was uneventful. She was discharged from the hospital on the 17th day, and is now doing well without any symptoms.
