Ross-Konno procedure in infants: mid-term results

Abstract

With the technical aspects of this procedure well accomplished, the risk of surgery is minimal and functional outcome is encouraging. However, early postoperative morbidity is significant. At the mid-term follow-up, there was no residual or recurrent outflow tract obstruction and excellent function of the neoaortic valve. A high incidence of MR associated with the development of EFE and structural abnormalities of the MV is worrisome; however, concomitant MV surgery is not associated with increased mortality. In the case of the development of EFE, an early indication for operation might protect MV function. The reoperation rate is high due to early conduit failure.
