ABSTRACT
An 83-year-old woman (BSA 1.36 m2) who had undergone aortic valve replacement (Magna ease 19 mm), mitral valve replacement (Epic mitral 25 mm), tricuspid annuloplasty (De Vega technique), and pulmonary vein isolation eight years earlier was referred to our hospital due to her heart failure symptoms. Ultrasound cardiography revealed severe mitral regurgitation due to perforation of bioprosthetic valve, severe mitral valve stenosis (mean pressure gradient 7.8 mmHg) due to bioprosthetic deterioration, and subsequent pulmonary hypertension (mean pulmonary artery pressure 49 mmHg, tricuspid regurgitation pressure gradient 85.5 mmHg). We performed a redo aortic valve (Inspiris 23 mm) and mitral valve (Epic mitral 29 mm) replacement using the Manouguian technique. The postoperative course was uneventful and pulmonary hypertension improved (tricuspid regurgitation pressure gradient 39.6 mmHg).
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.
