Stenting of the inter-atrial septum in infants and small children: Indications, techniques and outcomes (original) (raw)

To evaluate the procedural success and outcome of inter-atrial stenting. Inter-atrial stenting has been shown to be an effective way to maintain inter-atrial blood flow, however it is considered a high risk procedure, usually performed urgently in patients with significant hemodynamic compromise. Between September 2004 and August 2016, inter-atrial stenting was attempted in 29 children. Procedural, clinical, and follow-up data were collected retrospectively. The procedures were completed successfully in 27 patients. Twenty-five procedures were undertaken percutaneously, with the remaining four being performed as hybrid procedures. The patients were considered as high risk for adverse events (82% scored as CRISP 4 and 5) with four deaths during the first 24 hr (14%).

One further patient died after an uncomplicated technically successful stent implantation performed as a salvage proce...
