I'm not familiar with this feature, but I'll take a guess:
You don't want to create a map for PatientVisitSummary. You want to
import PatientVisitSummary into one of the mapped classes, such as Patient
or Visit. So don't create a PatientVisitSummaryMap, instead call ImportType
from your Patient or Visit map.
If this doesn't make sense then it would help if you could post the hbm xml
for this feature, it should be straightforward to provide the fluent version
based on that.
