    Abstract:
    AIMS: The lack of a specifically designed stent for the arterial duct has led to the off-label use of stents during hybrid palliation of hypoplastic left heart syndrome (HLHS). We evaluated the implantation and performance of a specially designed self-expanding stent in hybrid palliation of HLHS. METHODS AND RESULTS: We implanted 39 sinus-SuperFlex (SSF) stents in 24 patients at a median age of seven days (range 2-27 days) and median weight of 2.85 kg (range 1.3-3.8 kg). A single stent was implanted in nine patients and two overlapping stents in 15 patients. There was one intraoperative death, not related to ductal stenting and one additional in-hospital death. During median follow-up of 137 days (range 38-522 days), nine patients required 11 interstage interventions. Four patients have undergone a biventricular repair, 11 have undergone the next stage of univentricular palliation and seven are awaiting a second-stage palliation. CONCLUSIONS: The SSF stent provides effective maintenance of ductal patency in patients undergoing hybrid palliation of HLHS and its variants. It conforms to the ductal anatomy but the lack of stents longer than 20 mm has required overlapping stents in longer ducts. This has not been of haemodynamic consequence.
