Results of PPVI performed with routine prestenting have never been reported. <jats:styled-content>Methods:<\/jats:styled-content> Consecutive patients who underwent PPVI for homograft dysfunction with prestenting with BMS were studied. The schedule of follow\u2010up assessment comprised clinical evaluation, cardiovascular magnetic resonance, transthoracic echocardiography, and chest X\u2010ray to screen for device integrity. <jats:styled-content>Results:<\/jats:styled-content> PPVI was performed with no serious complications in all patients (<jats:italic>n<\/jats:italic> = 10, mean age 26.8 \u00b1 4.0 years, 60% males). In nine patients with significant pulmonary stenosis, peak right ventricular outflow tract (RVOT) gradient was reduced from a mean of 80.6 \u00b1 22.7 to 38.8 \u00b1 10.4 mm Hg on the day following implantation (<jats:italic>P<\/jats:italic> = 0.001). At 1\u2010month and 6\u2010month follow\u2010ups, mean RVOT gradient was 34.0 \u00b1 9.8 and 32.0 \u00b1 12.2 mm Hg, respectively. In patients with significant pulmonary regurgitation, mean pulmonary regurgitation fraction decreased from 19% \u00b1 6% to 2% \u00b1 1% (<jats:italic>P<\/jats:italic> = 0.0008). Relief of RVOT obstruction and restoration of pulmonary valve competence were associated with significant decrease in right ventricular (RV) end\u2010diastolic and end\u2010systolic volumes (125.5 \u00b1 48.6 to 109.2 \u00b1 42.9 mL\/m<jats:sup>2<\/jats:sup>; <jats:italic>P<\/jats:italic> = 0.002 and 68.4 \u00b1 41.5 vs. 50.9 \u00b1 40.6 mL\/m<jats:sup>2<\/jats:sup>; <jats:italic>P<\/jats:italic> = 0.001) as well as improvement in RV ejection fraction (48.8% \u00b1 13.1% to 57.6% \u00b1 14.4%; <jats:italic>P<\/jats:italic> = 0.003) and New York Heart Association class (<jats:italic>P<\/jats:italic> = 0.003). All patients completed 6\u2010month follow\u2010up.
