But at one point, the Whitehall woman was worried about her dancing future. Shirey was born with mitral valve prolapse, a condition that never interrupted her life until the summer of 2013 when she developed a serious infection. As a result, doctors at UPMC Shadyside found that she had mitral valve regurgitation, a condition that can lead to sudden cardiac arrest. Shirey needed surgery but hoped to delay it as long as possible out of fear of not being able to dance.
