Speaking to TMZ, the actress, who was nominated for the Primetime Emmy Award for Outstanding Guest Actress in a Comedy Series three times for her portrayal of Coach Beiste in the hit musical sitcom, was rushed to hospital by her wife Bridgett after experiencing a severe burning sensation in her chest.
While the star was diagnosed with bronchial spasms and asthma, the pain grew worse earlier this month and, while taking down her Christmas decorations, she was once again taken into medical care after suffering a widowmaker heart attack.
Dot's condition was severe, with one of her arteries being 99 per cent blocked, and surgeons inserted a stent in her heart to aid her recovery. She was treated by the same medical professionals that saved Bridgett's life following her 2017 stroke.
The publication reported the "Lizzie McGuire" star is now back home, resting and recovering.
