Katie Logan's heart could certainly use a credit of its own on "The Bold and the Beautiful" as it's had a lot of screen time and storylines over the years. However, the most pivotal moment for Katie's heart was when she needed a transplant after being shot by her own brother, Storm Logan (William deVry). According to Soaps in Depth, Katie found herself in the crossfire in 2008 after discovering Storm about to shoot Ashley Abbott (Eileen Davidson). While struggling with the gun, it went off and shot Katie in the chest. Devastated over what had happened, Storm ended his own life after hearing his sister needed a transplant so that she could have his heart. The surgery was a success, and Katie's lived with her brother's heart ever since.

However, that wasn't the only time that Katie's life was in peril. In 2019, the Logan sister dealt with another health crisis when she was diagnosed with kidney failure, per Soap Opera Spy. Tom told Parade that Katie's kidney failure was connected to the issues she had with her heart. The actor explained, "I think that this is probably not too far away from the truth, but Katie's on a tremendous amount of anti-rejection drugs, a whole plethora of drug cocktails to keep her heart from being rejected. That put a strain on her kidneys." The storyline even helped "The Bold and the Beautiful" raise awareness for kidney failure.

So, how are things looking for Katie and her heart today?
