Infectious false aneurysm of the right ventricular outflow tract after repair of congenital heart defect treated with Freestyle aortic bioprosthesis.

OBJECTIVES False aneurysm of the right ventricular outflow tract (RVOT) is one of complications after surgery of congenital heart disease. It is controversial about materials for reconstruction of RVOT in this setting, when associated with pulmonary hypertension or bacterial infection. Pulmonary homograft seems to be the first choice, but its availability is extremely limited in Japan. METHODS Therefore, we used Freestyle stentless bioprosthesis to reconstruct the RVOT in a 14-year-old boy who developed infectious false aneurysm of RVOT after total correction of pulmonary atresia with ventricular septal defect. RESULTS AND DISCUSSION After describing the patient, the prosthesis alternative to the pulmonary homograft was discussed.
