| Popis: | AIMS Residual gradients >20 mmHg after transcatheter valve-in-valve (ViV) implantation are associated with worse survival. This study aimed to evaluate the feasibility of high-pressure post-dilation with a non-compliant balloon after transcatheter ViV implantation in small surgical valves to optimise haemodynamics. METHODS AND RESULTS Thirty patients underwent ViV implantation in surgical valves with internal dimension ≤19 mm. High-pressure post-dilation to 16-20 atmospheres with a non-compliant balloon was performed in 12 patients and 18 patients underwent ViV without post-dilation. SAPIEN 3 and Evolut valves were used in 10 and two patients, respectively. The mean aortic valve (AV) gradient decreased by 11.3 mmHg following high-pressure post-dilation (18.7±7.9 mmHg immediately post ViV to 7.5±2.6 mmHg following high-pressure post-dilation, p |
