Aortic Homografts in Surgical Management of Prosthetic Valve Endocarditis: A Case Series from Greece
Am J Case Rep. 2024 Oct 12;25:e945030. doi: 10.12659/AJCR.945030.
ABSTRACT
BACKGROUND Infective endocarditis (IE) is a severe, life-threatening, and relatively common complication after valve replacement operations, with incidence rates varying between 1.8% and 5.8%, with an in-hospital mortality rate of up to 20%. Common microorganisms are (listed by decreasing incidence) Streptococci, Staphylococcus aureus, Enterococci, bacteria of the HACEK group, and fungi. Treatment of IE is complex, typically involving prolonged courses of antibiotics. However, in cases of aortic prosthetic valve endocarditis, root abscess formation with involvement of the aorto-mitral skeleton is not uncommon and complex surgical intervention is required. One of the notable advancements in surgical management is the use of homografts for aortic root endocarditis. CASE REPORT We report the first case series of 8 patients successfully operated on for prosthetic valve endocarditis with extensive aortic root abscess formation in Greece at Onassis Cardiac Surgery Center with the use of aortic homograft. All cases were redo surgeries and had good outcomes. Interestingly, one of the cases had extensive aortic root involvement with abscess formation extending to the aorto-mitral fibrous skeleton, requiring aortic root replacement with homograft, aorto-mitral skeleton reconstruction with bovine pericardium and mitral valve replacement with a mechanical prosthesis. Two other patients required concomitant coronary bypass grafting of the right coronary artery with reversed saphenous vein grafts. CONCLUSIONS Aortic root replacement with aortic homograft is the preferred choice for prosthetic valve endocarditis with aortic root abscess formation. Despite the technical complexity needed for implantation, this option offers a second chance for survival in patients with this challenging condition.
