Preparticipation screening-the way forward is smart screening.

The image of a young athlete collapsing on the pitch, followed by resuscitation, leaves an unforgettable impression. However, this impression should not seduce us into resuscitating the debate for large-scale preparticipation screening without doing the smart thing: taking a step back to review what we know to be effective, and what has been shown not to be effective. What we should do is use this momentum to focus on what we still need to know.
