Answer

Restenosis is common, particularly in patients with unicuspid valves or with valves affected by severe dysplasia (>60% at 6 mo, virtually 100% at 2 y). However, repeat procedures have been shown to provide a median survival rate of approximately 3 years and to maintain clinical improvement. [29]
