Isaac (played by Harvey Brook and Bobby Dunsmuir) was brought in for a routine check-up this evening, but it came with a devastating blow.

The check-up didn’t have the outcome that was expected by parents Moira Barton (Natalie J Robb) and Cain Dingle (Jeff Hordley).

Nurses at the clinic revealed the upsetting news and gave Isaac a diagnosis.

Following several tests, doctors believed that the baby may have a heart murmur.

Moira crumbled having already struggled to deal with becoming a mum again.

Cain tried his best to settle her fears and provide support for his ex, but the coming episodes will make it clearer on whether she can cope.

Viewers instantly took to social media following the tear-jerking scenes, with on tweeting: “This scene was heartbreaking to watch Moria struggling & Cain supporting her.”

“Seeing Moira like this just brings me straight back to last September when she found Holly. It’s heartbreaking to watch,” posted another.

A third added: “Why did it take so long to be discovered? My son has a hole in his heart, we found out when he was less than 12 hours old xx,” as another wrote: “Yey nice hug from Cain. What else would you need. Oh yes! Moira and Cain back together.”

A fifth said: “What are the writers doing to Moira, she’s already depressed and feeling guilty now Isaac has a heart murmur #Emmerdale.”

Another continued: "I love seeing Cain being so supportive of her and so tender. Can't wait to see how this continues. #Emmerdale #Coira."

Emmerdale continues tomorrow on ITV at 7pm.
