The 5-year-old Massachusetts boy whose reaction this past spring to the news he would be receiving a heart transplant, has died.

In an announcement made by his family on Friday via their Facebook page, 5-year-old, Ari Schultz, "passed away peacefully," while listening to the Red Sox.

Ari earned the nickname "Danger" by his family for his brave attitude amid a lifelong health battle that put him front and center with more than 10 operations, including the aforesaid heart transplant.

The news comes on the heels of the Mike and Erica Schultz revealing on their family blog, Echo of Hope, that Ari had been admitted to Boston Children's Hospital's emergency department and placed on life support.

"We called 911 at 4:19 a.m. as Ari was having a seizure," they wrote on their Facebook page and Echo of Hope blog Thursday morning. "Very scary. At the hospital now. Something is going on. We don't know what."

As chronicled by his parents, Ari's condition got worse and just after 10 a.m., he was coded into the emergency department and was given CPR for a half hour, being placed on life support in the cardiac intensive care unit.

The young boy's story went viral after video shared on March 3 showed the 5-year-old getting excited he would be receiving a new heart after spending 189 days in the hospital and 2011 days on a transplant list.

Sporting his Red Sox jersey and swinging around his baseball bat, Ari tells his parents, "They found one!" and asks if he could go to a baseball field afterwards or practice his golf swing in the backyard.

Ari was diagnosed at his 18-week ultrasound with "critical aortic stenosis and evolving hypoplastic left heart syndrome," and unfortunately, was the first person ever to undergo two successful heart surgeries before he was born.

Shortly after his surgery, Ari was healing, but his body was quickly rejecting the new organ as his parents shared via their family blog

"He went downhill and needed operations and procedures every day this week," Erica wrote. She added that since kids can't eat on surgery days, Ari had his food and water taken away every day.

"He's being brave and he's teaching us how to be brave," Erica said in a video posted on the blog.

The family has set up a GoFundMe to cover costs for Ari's medical treatment and their new home, as they wrote that insurance will only pay to remove the mold, not fix the issue.
