A dying boy walked away from everything he loved to save his family from watching him die — and what happened next changed the world of heart surgery forever.
Mesfin Yana was born in 1985 in Shafina, a tiny village in southern Ethiopia. There were no cars, no electricity, no running water. His family were coffee farmers. He had thirteen brothers and sisters. And by every measure that mattered to him, he was happy.
Then, around the age of ten or eleven, he got a sore throat. It seemed like nothing. But in a place with no hospitals and no antibiotics, nothing can become everything. That untreated strep throat quietly turned into rheumatic fever, and rheumatic fever slowly destroyed the valves of his heart.
By the time Mesfin was fifteen, he was dying.
His parents took him to a local doctor, who could only deliver the truth: the boy needed heart surgery, and there was no heart surgeon in the entire country for nearly a hundred million people. There was nothing anyone could do.
So Mesfin made a decision that no child should ever have to make. Rather than force his family to watch him waste away, he left home. He walked miles from his village to the city of Awassa, alone, sick, and barely strong enough to stand. A local shelter run by Mother Teresa’s Missionaries of Charity took him in, and later transferred him to another shelter in Ethiopia’s capital, Addis Ababa.
There, his condition continued to worsen — until one day, an American doctor named Rick Hodes walked through the door. Dr. Hodes, an internist who had spent decades caring for the poorest patients in Ethiopia, examined Mesfin and diagnosed him with severe congestive heart failure. The boy’s heart was failing. But Dr. Hodes refused to accept that as the ending.
He reached out to his colleague and close friend in Atlanta — cardiologist Dr. Allen Dollar — and together they arranged for Mesfin to fly to the United States for open-heart surgery. At Piedmont Heart Institute, cardiothoracic surgeon Dr. Jim Kauten repaired Mesfin’s damaged mitral valve.
The surgery was a success. Mesfin returned to Ethiopia, and for a brief, beautiful moment, it seemed like the story had its happy ending.
It didn’t. Not yet.
Six weeks later, Mesfin developed a dangerous infection called endocarditis — an inflammation of the heart lining triggered by a dental procedure he’d had while in the U.S. His repaired valve was being destroyed all over again. Dr. Hodes contacted Dr. Dollar, and once more, the two doctors pulled Mesfin back to Atlanta.
This time, during surgery, the team discovered the valve was beyond saving. They replaced it with a mechanical one — a device that would keep him alive but required lifelong blood thinners and constant medical monitoring. The kind of monitoring that simply did not exist in rural Ethiopia.
Mesfin could not go home.
Dr. Allen Dollar called his wife, Shelly, from the hospital. “I think we’re going to have another kid,” he said.
The Dollars were no strangers to opening their home. They already had biological daughters and adopted children from China, El Salvador, and Mexico — many with serious health conditions. Mesfin joined their family in Atlanta, eventually taking their last name. He later said it reminded him of home: “This is as large a family as I had back in Ethiopia.”
And then, quietly, something remarkable began to happen.
Mesfin studied harder than anyone the Dollars had ever seen. He learned English, caught up to his peers, and threw himself into academics with a focus that stunned his teachers. He enrolled at Georgia State University to study respiratory therapy. There, he met his future wife, Iyerusalem. They married and had two sons.
But Mesfin wasn’t done. He moved his young family to Texas and trained as a cardiac perfusionist at the Texas Heart Institute — learning to operate the heart-lung machine, the very device that had kept him alive during his own surgeries. He eventually landed a position at the Mayo Clinic in Minnesota, where he now runs heart-lung machines during some of the most complex open-heart surgeries performed anywhere in the world. His wife works there too, as a cardiac sonographer.
The first time Mesfin assisted in surgery, his patient was a teenage girl from Ethiopia. She was terrified, crying on the operating table. He walked to her bedside and spoke to her in Amharic. “I had the same surgery,” he told her gently. “Things are going to be just fine.”
Years later, he still sees himself in every patient. “I was on that same operating table,” he says.
Today, Mesfin flies back to Ethiopia regularly alongside Dr. Jim Kauten — the very surgeon who once opened his chest to save his life. Together, through the nonprofit Heart Attack Ethiopia, they perform life-saving heart surgeries for patients who, like Mesfin once was, have no other option. He serves not only as a perfusionist but as an interpreter between Ethiopian and American medical teams, bridging two worlds that shaped him.
He also did something else that speaks to who he truly is: he helped bring his biological parents and several of his siblings to the United States, reuniting the family he once walked away from to protect.
“I’m always grateful,” Mesfin says. “I’m grateful for my family, for just being in the United States. It’s a resurrection for me. You know, I was once lost, dead, and I was resurrected and I’m living a new life.”
His adoptive father, Dr. Allen Dollar, puts it simply: “He has retained this spirit of gratitude. He has never lost sight of what his life could have been, and all the people along the way.”
Mesfin Yana Dollar was once a dying boy who walked away from home so his family wouldn’t have to watch him go. Today, he stands in operating rooms at one of the world’s greatest hospitals, keeping hearts beating with the same machine that once kept his own alive.
Some people are saved so they can save others. Mesfin is living proof.
