Heart transplantation as salvage treatment of intractable infective endocarditis

Case Report: Heart Transplantation for Refractory Candida tropicalis Endocarditis: A Case Report and Literature Review

Candida infective endocarditis presents therapeutic challenges with high mortality. A complex case of Candida prosthetic valve endocarditis refractory to standard antifungals (anidulafungin and fluconazole) and high-dose caspofungin was successfully treated with heart transplantation. The literature review revealed a few cases of bacterial endocarditis successfully treated with heart transplantation, but with only two transplanted cases of fungal endocarditis. This report explores heart transplantation as a last resort for managing refractory infective endocarditis. The patient is still alive and free of infection, two and a half years after transplantation.

Partial heart transplantation for destructive infective endocarditis

Infective endocarditis frequently spreads beyond the valve tissue, especially in the aortic location. Invasive endocarditis may lead to abscess formation or fistula, with substantial tissue loss. Here, the case of a 31-year-old male patient with destructive aortic and pulmonary valve endocarditis and a subaortic mural defect who underwent patch closure of the ventricular septal defect and aortic and pulmonary root replacement and right coronary artery bypass graft is presented. This is an uncommon condition and stress is placed on imaging of the technical aspects of the case.

First case report of Candida guilliermondii native left-sided valve endocarditis

Endocarditis, a life-threatening inflammation of the endocardium, is incited by bacteria, fungi, or other pathogenic microorganisms. Fungal endocarditis closely mirrors bacterial endocarditis in clinical signs and symptoms, leading to potential misdiagnoses. Here, we unveil the inaugural confirmed instance of native left-sided valve endocarditis attributed to Candida guilliermondii. Diagnosis was substantiated through valvular biopsies, blood and vegetative cultures. Treatment encompassed surgical excision of vegetations along with a six-week regimen of fluconazole administration (12 mg/kg/day), followed by 4 years of meticulous monitoring, resulting in sustained patient recovery.
