I realize this thread is a few months old but I wanted to respond to this inquiry about accuracy. As a congenital heart patient and nurse, I can tell you it’s definitely not accurate. I was born with several congenital heart defects and had multiple surgeries as a child, including a valve replacement. Granted, it was an aortic valve replacement but Laura could most definitely be a candidate for a mitral valve repair or replacement and worst case scenario, a transplant. People with heart defects (surgery or no surgery) are at risk for arrhythmia and sudden cardiac arrest but that would more likely be from lack of intervention on her valve which led to an enlarged heart.
