Acutely, there was no difference in haemodynamic outcomes. Serial echocardiography revealed that in the subgroups of \u2018moderate\u2019 (26\u201340\u2005mm\u2002Hg) and \u2018severe\u2019 (>40\u2005mm\u2002Hg) right ventricular outflow tract (RVOT) obstruction, patients with pre-stenting showed a tendency towards lower peak RVOT velocities compared to patients after PPVI alone (p=0.01 and p=0.045, respectively). The incidence of PPVI stent fractures was not statistically different between treatment groups at 1 year (PPVI 31% vs BMS+PPVI 18%; p=0.16). However, pre-stenting with BMS was associated with a lower risk of developing PPVI stent fractures (HR 0.35, 95% CI 0.14 to 0.87, p=0.024). The probability of freedom from serious adverse follow-up events (death, device explantation, repeat PPVI) was not statistically different at 1 year (PPVI 92% vs BMS+PPVI 94%; p=0.44).<\/jats:p>\n <\/jats:sec>\n \n Conclusions<\/jats:title>\n Pre-stenting with BMS before PPVI is a feasible and safe modification of the established implantation protocol.
