Mateo's story

May 6, 2026

Mateo is a toddler from Bolivia. He is his parents’ first child. He lives with his mom, who is a homemaker, and his dad, who works distributing soda.

When he was born prematurely at 30 weeks, Mateo had to be in an incubator where doctors detected his heart condition. Mateo has a cardiac condition called tetralogy of Fallot (ToF), a combination of four heart conditions, including a hole between the two lower chambers of the heart, as well as a blockage that affects how blood flows out of the heart. As a result, Mateo does not get enough oxygen, leaving him weak and short of breath.

On May 6th, he will undergo cardiac surgery at our medical partner’s care center, Hospital del Niño Dr. Ovidio Aliaga Uría. During surgery, doctors will close the hole in his heart and remove the blockage so that blood can flow more normally.

Mateo’s family needs help to fund the costs of cardiac care and surgery. Our medical partner, International Cardiac Alliance, requests $1,500 to cover the cost of cardiac exams and diagnostics, surgical costs, follow-up care, and medications.

Mateo’s mother shared, “I’m grateful my child is going to receive his surgery so he can grow and be a healthy boy.”

Symptoms

Cultural or regional significance

What kinds of symptoms do patients experience before receiving treatment?

When a hole exists in the heart, a physician can hear a buzzing noise, or murmur, in the child's chest as blood passes through the hole at high velocity. Parents might notice that their child cannot keep up with other children in daily activities. In severe cases, the lack of oxygen in the bloodstream can lead to dramatic symptoms, such as blue lips and tongue, clubbed fingers and toes, and heart failure.

What is the impact on patients’ lives of living with these conditions?

Most congenital cardiac conditions will eventually lead to death without surgery, often within a period of months or years depending on severity. In the meantime, patients experience heart failure as their hearts struggle to compensate for the presence of leaks or other defects. In most conditions, the heart becomes fatigued, limiting the child's ability to be active, go to school, and participate in daily life.

What cultural or regional factors affect the treatment of these conditions?

Pediatric open-heart surgery has only been made available in Bolivia in recent years. Most families are unfamiliar with the concept of open-heart surgery and are at first quite reluctant to allow their child to undergo this care. Indigenous belief systems in Bolivia can at times contribute to a family's reluctance to proceed with surgery, and must be addressed through thoughtful conversation and social accompaniment of each family.

What does the treatment process look like?

The child's cardiac symptoms are usually first detected by their local pediatrician, who then refers the child to the nearest pediatric cardiologist for exam and diagnosis. Once diagnosed, HCA works with the local cardiologist and the surgical team in La Paz to ensure that the child is enrolled on the waiting list for surgery at the hospital, and works directly with the family to facilitate their transportation to La Paz, often from very long distances, and to support them socially and logistically after arrival. The child then undergoes surgery and recovers for about a week in La Paz before returning home to their community. HCA then coordinates with the child's pediatric cardiologist to ensure high-quality, long-term follow-up care, and provides financial support for medications and doctor visits as needed.

What is the impact of this treatment on the patient’s life?

These treatments are almost always life-saving in nature as the cardiac conditions are not survivable over the long-term without surgery. Within weeks after surgery, the patient should already notice a difference in energy level. Many patients also undergo a growth spurt and/or gain significant weight after a surgery.

What potential side effects or risks come with this treatment?

The risk of death during or shortly after an open-heart surgical procedure is about 3%. Other risks, though rare, include stroke and post-operative infection. In a small percentage of cases, the material used to patch the hole will separate from the edges of the hole, and a follow-up surgery is necessary to re-patch the defect.

How accessible is treatment in the area? What is the typical journey like for a patient to receive care?

For families without private-sector insurance, the cardiac surgery program in La Paz is the only year-round surgical program in Bolivia capable of treating children who need open-heart surgery. Children come to this program from throughout Bolivia; many families live in extremely remote and mountainous areas that can require several days of overland travel to reach La Paz. For patients who live more than 8-10 hours away by road, HCA arranges for families to come by plane from the nearest commercial airport to their home.

What are the alternatives to this treatment?

In general, patients are treated with medications to prevent heart failure until they are able to obtain their surgeries. Patients may also seek care from traditional healers, who may use liquids and powders derived from local plants and roots.

Hadassa is a seven-year-old girl from Haiti. She is the middle child in her family, with an older sister and a younger brother. She does not currently attend school but enjoys helping her parents around the house and watching cartoons. Hadassa has a cardiac condition called a partial atrioventricular canal defect. A hole exists between the chambers of her heart, causing blood to leak between them instead of properly circulating through the lungs to receive oxygen. This leaves her weak and short of breath. Hadassa also has Down syndrome. Hadassa needs to fly to the Dominican Republic to receive treatment. On June 24th, she will undergo heart surgery, during which doctors will repair the hole in her heart. Another organization is paying for the surgery, but her family also needs help with travel and surgery prep. Our medical partner, International Cardiac Alliance, is requesting $1,500 to cover labs, medicines, and check-up and follow-up appointments. It also supports securing travel documents for the family and travel costs for the social workers from our medical partner, who will accompany Hadassa's family overseas. Hadessa’s mother shares, “Our family is so happy to know that there is a way to fix our daughter’s heart, and we hope everything will go well!”

Ronaldo is a three-year-old boy from Tanzania. He is the youngest of seven children. Ronaldo is a cheerful and energetic kid who loves playing and having fun with those around him. His father works as a casual laborer to support the family. Ronaldo was diagnosed with bilateral genu valgum, a condition that causes his legs to angle inward at the knees. Several factors can cause this condition, such as growth disorders, vitamin deficiencies, or excessive fluoride found in contaminated drinking water. As a result, the knees can be angled inwards or outwards, making it difficult to walk and may cause long-term joint damage. As Ronaldo has grown, his parents have become increasingly concerned about how the condition may affect his ability to walk comfortably and participate fully in daily activities. They also worry about the challenges he may face when he starts school in the future. Ronaldo's family is seeking care in the hopes that undergoing treatment will give Ronaldo the best possible start in life and allow him to grow, play, and attend school without difficulty. Our medical partner, African Mission Healthcare (AMH), is helping Ronaldo undergo treatment on June 2nd. This treatment will restore Ronaldo's mobility, allow him to participate in a variety of activities, and greatly decrease his risk of future complications. AMH is requesting $777 to fund his surgery. Ronaldo's mother said, "We want Ronaldo to grow up strong, walk comfortably, and one day go to school like his brothers and sisters."

Roberto is a resilient 56-year-old man from the Philippines. He is currently unemployed and relies on his brother for food and daily support. He had previously worked as a messenger but had to stop after being advised by the doctor to avoid lifting heavy objects. Two months ago, Roberto was diagnosed with an inguinal hernia, a condition that occurs when abdominal tissue protrudes through a weak spot in the lower abdominal muscles, causing a bulge in the groin area. The condition has caused him anxiety and has prevented him from working. Doctors have recommended a hernia repair surgery to treat his condition. Fortunately, on May 16th, Roberto will undergo hernia repair surgery at our medical partner's care center, Our Lady of Peace Hospital. A portion of the cost of treatment is being supported by the Philippine Health Insurance Corporation. Our medical partner is raising the remaining $1,038 to cover the cost of his surgery and care. Once completed, this procedure will hopefully allow him to live more comfortably and confidently. Roberto says, "Many thanks to the foundation and to all the people who helped me and became instruments of God in supporting me through this difficult time. May God continue to guide, protect, and bless you, and may your kindness be returned to you many times over."
