The SelectionChanged event fires when an item is selected or deselected. If you only care about when an item is selected, try checking if the item is selected first.

Private Sub ListView1_ItemSelectionChanged(sender As Object, e As ListViewItemSelectionChangedEventArgs) Handles ListView1.ItemSelectionChanged
    If Not e.IsSelected Then Exit Sub
    Select Case e.ItemIndex
        Case 0
            MessageBox.Show("AAAA")
    End Select
End Sub
