Doctors from developed countries routinely travel to impoverished nations on "medical missions," working through nongovernmental organizations to provide free health care not available in local clinics.
Some missions provide surgical services. The Children's Heart Fund of Ethiopia has benefited from charitable support from the Minneapolis Heart Institute Foundation and medical device companies like Medtronic and St. Jude Medical to perform surgeries on hundreds of kids whose heart valves are severely damaged from failing to get penicillin for strep throat.
But performing heart-valve surgeries one at a time is an expensive solution that can't address the underlying problems that make rheumatic heart disease the most prevalent heart condition in children and young adults in Ethiopia, a nation of 94 million people.
A 2015 study by doctors in Minnesota and Ethiopia found that one-third of 6,275 patients with cardiovascular problems treated at Ethiopian hospitals had rheumatic valvular heart disease, typically caused by strep throat progressing to rheumatic fever without treatment.
Rheumatic valvular heart disease is a major problem for kids and teens in countries lacking access to cheap antibiotics. Stamping it out requires both innovative prevention strategies and also treatment for advanced cases that will inevitably turn up through increased outreach efforts.
By 2012, indigenous and international efforts had led to construction of a new heart hospital in the Ethiopian capital, Addis Ababa, and the establishment of a revenue stream to run it, using rental income from apartment buildings that were built to support the hospital.
But a dearth of local specialty talent in heart care left the hospital unable to operate without regular medical missions of physicians from Europe and the U.S., including several from Minnesota. Worse, there was no training program in Ethiopia that could prepare a full-time team for pediatric heart surgery.
"You need three things to make this work," said Minnesota resident Wendy Bennett, a global-health consultant and co-founder of Minnesota's Friends of Children's Heart Fund of Ethiopia within the Minneapolis Heart Institute Foundation.
