Abstract
The increasing use of transcatheter aortic valve replacement (TAVR) has led to a rise in cases of infectious endocarditis (IE), a serious complication. For patients who can tolerate surgery, transcatheter heart valve (THV) explantation is considered, though it carries risks of injury to adherent tissues. This report presents a method to minimize such risks during THV removal. An 82-year-old man with hypertension, smoking history and dyslipidaemia underwent TAVR with a 29-mm Evolut FX bioprosthetic valve. Six months later, he developed a fever, and blood cultures revealed Streptococcus gordonii, leading to an IE diagnosis. Despite 3 months of antibiotics, a transoesophageal echocardiogram revealed vegetation growth and valve leakage, necessitating surgery. During the operation, the aorta was incised, and a novel technique using a vinyl chloride tube was employed to retract and protect the THV's stent frame. This approach helped detach adhesions with minimal tissue damage. The infected valve was successfully replaced with a bioprosthetic valve. By reducing adherent tissue injury, this technique could improve patient outcomes and decrease the need for additional procedures. Explantation of THVs with minimal tissue damage reduces the risk of concomitant procedure and results in low mortality.
