Well, the good news is that in many cases, it doesn’t affect them at all. The syndrome is often asymptomatic. That is, patients don’t have any symptoms. Often patients aren’t diagnosed with this condition until they are teenagers. In other cases, people with this condition complain of shortness of breath, fatigue… This is generally when we start discussing treatment options. However, in rare cases, this syndrome can lead to sudden death. The most common way people hear about this condition is when a high school’s athlete dies suddenly during a practice or a game. It can also occur during sleep. And sadly, sudden death is the first indicator that someone has this condition.
