A 48-YEAR-OLD man underwent redo aortic valve replacement for severe symptomatic regurgitation of a biopros-thetic aortic valve. Three months postoperatively, he presented to the hospital with a second-degree atrioventricular block requiring insertion of a dual-chamber permanent pacemaker. He subsequently developed Peptostreptococcus endocarditis involving the newly implanted bioprosthetic aortic valve and required subsequent aortic valve re-replacement. Unfortunately, he required a total of 5 sternotomies because of further complications including the need for ascending aortic graft replacement and sternal debridement.
