Emma Anne Shourds Carlin Bates Says 15-Week-Old Daughter Has "Small Hole in Her Heart" and "Breathing Problems" Last year, Alyssa — who has a type of supraventricular tachycardia, in which the heart beats very fast for a reason other than exercise, high fever or stress from time to time — underwent two surgeries related to the condition, first in April and then again in August. "For the past several months Alyssa has been having some irregular heart beats and we have been in and out of doctors offices and specialist to find the problem," John wrote in April 2019 on his wife's Instagram. "They found that she had superventricular tachycardia (SVT) which can be fixed with an EP (electrophysiology) study procedure." Doctors were able to successfully ablate the arrhythmia during the surgery, John confirmed. Unfortunately, it returned, Alyssa revealed that August — but the second procedure (also six hours long, just like the first) seemed to prove more successful. "My doctor said I have won the award for the worst case he's seen for SVT AVNRT," Alyssa captioned an Aug. 30 snapshot of herself and her husband from her hospital bed. "He really thinks he fixed the problem this time (we just won't know for sure for a few more days) but I am so happy that I might be back to normal soon!"

Alyssa confirmed on Instagram the following month that "the second surgery was a success" — and also revealed that she "had all three of [her] children in a birthing center all naturally with no pain medication. 😳" John and Alyssa tied the knot on May 24, 2014. For their six-year wedding anniversary, John posted a touching tribute to his wife, saying she is "perfect" for him and "completes me in every way." "Challenges me to be a stronger Christian, encourages me when I get discouraged, and forgives me when I let my pride take over," he continued. "She gives everything for the girls and I and expects nothing in return. She is strong and firm in what she believes but yet kind and compassionate. Alyssa is my best friend, my most trusted companion, and the love of my life!" Season 9 of Bringing Up Bates is currently airing Thursdays at 9 p.m. ET on UPtv.
