Payments from drug & device makers
What this record shows
The money is spread across several categories — consulting fees (41.5%), speaking fees and travel and lodging — rather than concentrated in one kind of arrangement. 8 manufacturers reported payments, led by Medtronic at 40.5% of the total. Reporting peaked in 2019 at $61,029 and has fallen 59.3% since, to $24,818 in 2025. Among pediatric cardiology clinicians in MO with any reported payments, this total sits in the top 5% — high for the specialty, which is a reason to read the composition above rather than the number alone.
Across 303 payments — averaging $597.23 each. Meals, travel, consulting and speaking fees, gifts and royalties reported by drug and device makers.

What the payments were tied to
Products named in the reported payments. Only payments of $100 or more are attributed here — the typical reported payment nationally is a meal worth about $16, and listing those product-by-product would be noise.
