Successful surgical experience for acute severe aortic valve regurgitation with acquired Gerbode defect: A case report

Abstract

Introduction and importance: The incidence of acquired Gerbode defect has been increasing due to advances in cardiac imaging technology, and some closure methods have been introduced.

Presentation of case: A 58-year-old man developed cardiogenic shock due to acute severe aortic valve regurgitation with an acquired Gerbode defect caused by infective endocarditis. Emergency surgery was performed. A large patch with a 0.4 mm extended-polytetrafluoroethylene (e-PTFE) sheet covered with autologous pericardium was used to close the Gerbode defect, and a bioprosthetic valve was used for aortic valve replacement.

Clinical discussion: Large patch closure with 0.4 mm e-PTFE sheet and autologous pericardium for fragile Gerbode defect caused by infective endocarditis might be effective with regard to sturdiness, good fitting to the tissue, and excellent resistance to bacteria.

Conclusion: We encountered a rare case of cardiogenic shock due to acute severe aortic valve regurgitation and acquired Gerbode defect caused by infective endocarditis. In our case, large-patch closure for perforation in a fragile membranous septum was effective.
