Son Uses Grandfather's Heartbeats to Help Save Mom's Life

Courtesy Andrew Josephson(MOORESTOWN, N.J.) -- Dr. Daniel Mason, a prominent cardiologist, had a big heart, taking an active interest in each one of his grandchildren's summers on New Jersey’s Long Beach Island until his death in 2011 at age 92.

But he left behind another kind of legacy for his family, one that set his grandson Andrew Josephson on the path to medical school and, inadvertently, but luckily, helped to save his mother’s life.

Mason, who lectured and practiced for 50 years at Philadelphia’s Hahnemann Hospital, had produced a three-CD set of digitized heart sounds and murmurs, some extremely rare, to teach medical students the nuances of detecting heart disease.

“Whenever someone had a patient with an irregular pattern with their heart sounds, he would grab his recording equipment,” grandson Josephson said. “He used them as a teaching tool for students and cardiologists and other physicians in the field, anyone who used a stethoscope.”

“My grandfather was such an influence in my life,” Josephson, 23, who lives at home in Moorestown, N.J., said.

That was an understatement.

Josephson, after his graduation in biochemistry from Lehigh University in Pennsylvania, discovered on the family bookshelf his grandfather’s collection of 125 or more heart sounds, and created an app, “Listening to the Heart,” that uses the iPhone to record a person’s heartbeat, compare it to Mason’s recordings, and identify any abnormalities.

And in the process this year, he diagnosed his mother’s silent heart disease.

It all started in 2011, when Josephson was on a gap year and considering applying to his grandfather’s alma mater, Drexel University in Philadelphia.

“I was going through his stuff after he died and discovered the CDs,” he said. “He had spent years running around the hospital recording people. I thought about doing something with them, to republish them was my initial goal.”

As Josephson thought about it he was inspired by the music app Shazam, which matches songs with a musician’s body of work. Although he had taken only had one computer programming class in college, he bought some books and taught himself to learn writing code.

“With the platform of the iPhone, I extracted all the sample sounds he had recorded from lectures and did a little acoustic analysis on the computer,” Josephson said.

“At first, we really weren’t sure it worked,” he added. “I was not the most reliable programmer.”

He had to tweak the iPhone’s microphone but soon figured a way to hold the iPhone up to the chest and compare and analyze the sound to match the recordings in his grandfather’s collection and to get the five closest matches.

Josephson first began experimenting on friends and found that their heart sounds yielded “normal” results.

By 2013, one of his first guinea pigs for the prototype was his mother, Dr. Tina Josephson, the daughter of Daniel Mason and an internist in Cherry Hill, N.J.

“Mom kept coming up with the same abnormal heart sound,” he said. “We did it multiple times and in multiple locations and got the same result.”

Even though she had “complete faith” in her son, Tina Josephson ignored the results: a heart murmur, suggesting a potentially dangerous condition. “I was probably in denial,” she said, laughing. “I’m a doctor. I never get sick.”

But when the family went out to Steamboat Springs in Colorado to ski this year, she noticed a difference in her breathing.

“I really didn’t notice anything until I was skiing at 10,000 feet and I was more short of breath than I normally get,” Josephson, 54, said. ”I knew there was nothing wrong with my lungs; I never smoked. It was probably my heart.”

Remembering the iPhone app when she returned home, she went to a cardiologist who ordered an echocardiogram, which confirmed the app’s diagnosis: a murmur suggesting mitral valve prolapse and mitral valve regurgitation, which would require surgery.

In mitral valve regurgitation, the valve doesn’t completely shut and instead of the blood moving forward, it goes back a little when the valve tries to shut. Left untreated, it can lead to heart failure and eventual death.

“My father’s dream was to always have this as an educational tool,” she said. “That’s why he produced the CD in the first place. I am sorry he didn’t get to live to see the iPhone app. In his last days, he was always working on a project with heart sounds. He was very active.”

Apple has approved Andrew Josephson’s app and it is now available at the App Store for $19.99. “My audience is mainly the same as my grandfather’s -- nurses, doctors, clinicians, home health care aides and EMTs -- anyone who carries a stethoscope,” he said. “My goal is educational.”

Tina Josephson said her father would have been proud to know his grandson’s app had helped to save his mother’s life. She is scheduled to have surgery for her mitral valve regurgitation in two weeks.

“I have no symptoms,” Tina Josephson said. “I run every day.”

She said her father was never prouder than when three of his four daughters became doctors. And Mason’s grandson will hopefully follow in his footsteps when medical schools send out their letters of acceptance in April.

“The app is something very exciting, though it’s not something I wanted to happen to me,” Tina Josephson said. “I was the daughter of a cardiologist. How could there be anything wrong with my heart?”
