Fig 2 Representative angiography at the 3-month follow-up demonstrating a competent valved stent in the pulmonary position. Chronological sequence from a to d. (a) Early phase; (b) complete contrast in the pulmonary arteries; (c) still complete contrast in the pulmonary arteries without regurgitation; (d) late phase.
