Materials and methods
We retrospectively analyzed the medical records of five patients (three men, two women; mean age, 50.0 ± 13 years; age range, 37–63 years) who underwent extensive mitral valve reconstruction with fresh autologous pericardium and artificial chordae for treatment of destructive active infective endocarditis of the mitral valve from January 2011 to December 2020 at our hospital. The patients’ preoperative demographic and echocardiographic data are presented in Table 1. The mitral regurgitation was severe in four patients and moderate in one. All patients had good preoperative cardiac function (mean left ventricular ejection fraction, 70% ± 5%) and a stable respiratory condition.
