It looks like the concept with concept_id = 44830486 is a non-standard concept that maps to several standard concepts that seem to be somewhat not the same:

It looks like this list can not be narrowed down to a single standard concept using the concept_relationship valid_start_date and valid_end_date, the concept valid_start_date and valid_end_date, domain_id, and invalid_reason.
How do I pick which standard concept to use?
Here is a query that provides some useful information:
select
rel.concept_id_1,
rel.concept_id_2,
rel.valid_start_date,
rel.valid_end_date,
con.*
from
omop_concepts.concept_relationship rel
join omop_concepts.concept con on rel.concept_id_2 = con.concept_id
where 1=1
and rel.concept_id_1 = 44830486
and rel.relationship_id = 'Maps to'
order by
rel.valid_start_date,
con.valid_start_date
;
