Modified Aortic Root Remodeling Combined with Aortic Valve Repair Technique for Severe Aortic Regurgitation Resulting from Prolapse of the Right Coronary Cusp and Aortic Root Dilatation / 日本心臓血管外科学会雑誌

ABSTRACT

A 70-year-old man who had been followed up in our outpatient clinic for mild aortic regurgitation underwent curative surgery for progression of the regurgitation due to a prolapsed right coronary cusp, associated with annular dilatation and aortic root aneurysm formation. The Operation consisted of subvalvular circular annuloplasty to reduce the size of the aortic annulus, adjustable leaflet suspension for the prolapsed right coronary cusp, and modified aortic root remodeling, which replaced the Valsalva sinus of both non and right coronary cusps while sparing the Valsalva sinus of the left coronary cusp. Coronary artery bypass grafting was additionally performed for the 90% stenosis of the proximal right coronary artery segment. The postoperative course was uneventful with no need of blood transfusion. He was discharged from the hospital 10 days postoperatively. This combination of valvuloplasty with valve-sparing aortic root reconstruction procedure can be useful.
