Inverted aortic bioprosthetic for mitral valve replacement with Ross procedure: case report

Abstract

Abstract Background A 34-year-old gentleman presented with Staphylococcus salivarius infective endocarditis 13 years after aortic homograft and mitral valve repair for degenerative bicuspid aortic valve associated with rheumatic heart disease. The homograft had calcified, and the mitral repair had deteriorated with severe regurgitation. Multidisciplinary team decision to restore best quality of life was for re-do Ross procedure with bi-leaflet preserving mitral valve replacement with an inverted RESILIA aortic valve as the patient was fundamentally against lifelong anti-coagulation. Case presentation The aortic homograft was excised, and coronary arteries dissected out followed by harvesting of the pulmonary autograft. The mitral valve was accessed via a trans-septal approach. On examination, there was a restricted and thickened posterior mitral valve leaflet. An inverted 27-mm INSPIRIS RESILIA aortic bio-prosthesis was placed with mitral cusps preserved. The pulmonary autograft was implanted in an intra-annular position, and a 26-mm pulmonary homograft was used to replace the pulmonary valve. Echocardiogram at 4 weeks revealed preserved LV function and well-functioning prosthetic, autograft and homograft. Conclusion An inverted RESILIA valve, with its anti-structural valve deterioration properties, can be used in the mitral position with preservation of the mitral cusps to avoid anti-coagulation with the hope of reducing need for re-operation in line with patient wishes.
