Implication
May support repeat PPVI for early failure; hypothesis-generating and should not yet change practice.
Structured PICO
Does repeat percutaneous pulmonary valve implantation improve hemodynamics and prevent re-intervention in patients with early device failure?
P
Population
20 patients with right ventricular outflow tract (RVOT) obstruction due to early device failure ('Hammock effect', 'Hammock-like effect', stent fracture, residual stenosis) after initial percutaneous pulmonary valve implantation.
I
Intervention
Repeat percutaneous pulmonary valve implantation (valve-in-valve).
C
Comparator
Index procedure (initial percutaneous pulmonary valve implantation).
O
Outcome
Catheter-measured RVOT gradient and right ventricular systolic pressure (RVSP), and freedom from re-intervention.surrogate
Repeat percutaneous pulmonary valve implantation is a feasible and effective treatment for early device failure, significantly improving hemodynamics and reducing the need for further re-intervention.
