Abstract:

The final flow rate through a stented duct is variable and depends on stent diameter, ductal length, and ductal tissue protrusion after ductal constriction. Typically after duct stenting, there is initially mild overperfusion which may require some antifailure treatment. Severe heart failure is uncommon, but in some cases flow reduction is required. We present a case of overperfusion after arterial duct stent implantation which was successfully managed with implantation of covered stents. © 2015 Wiley Periodicals, Inc.
