Commotio cordis or cardiac concussion is a cause of sudden death in young baseball players. It is the result of a low velocity impact to the chest from a thrown or batted ball traveling usually at a speed of between 20-50 mph. The impact must occur directly over the heart, the closer to the center the greater the risk. The cause of death is the development of an abnormal rhythm, ventricular fibrillation, though there may be some affect on the blood circulation to the heart as well. For the catastrophic event to occur, the impact has to be precisely timed to strike the heart during a 15-30-millisecond phase of the electrical cycle (during repolarization or just before the peak of the T-wave).

Commotio cordis is associated with a death rate of 90%. The lack of response of these young health baseball players to CPR is unexpected and remains unexplained, but it is clear that a rapid response is essential. This response is probably required in three-five minutes…….

Batters should learn ball avoidance and turn away from an inside pitch and not open chest to the impact, as is so typically the case. Avoidance while bunting requires special attention. Pitchers as well should be coached in proper fielding positions and ball avoidance when necessary. Chest wall protectors that are commercially available have not been demonstrated to prevent commotio cordis. Studies with baseballs seems to indicate that lighter and softer balls may diminish the risk, but their acceptability for play by older children is of question.

In My Opinion: Studies indicate that the chances of survival of a commotio cordis incident is enhanced if a shock from an AED can be delivered promptly. Most ball parks don’t have AED’s and those that do must have well practiced procedures in place for the rapid use of the device or all if for naught. I am often amazed at the marketing efforts by the vendors of chest protectors. It makes sense that they would help but the scientific studies indicate that many don’t offer any protection and may actually be contra indicated. Apparently, most chest protector vendors need to go back to the drawing board with their designs. Also, the recent high profile lawsuit in New Jersey of a pitcher being stuck by a batted ball that came off of an alleged “hot bat” involves commotio cordis and resulting permanent disability to the pitcher. The metal bat manufacturer was sued among others. What is interesting to note is that commotio cordis usually occurs only when a projectile travels at a relatively slow speed between 20-50 mph and in this case the basis for the lawsuit is that the ball speed was too fast as a result of the alleged “hot bat”.

Use Of Reduced Impact Ball In Youth Baseball: Safety Balls

“Based on the research performed by USA Baseball and other investigators demonstrating that a reduced impact ball can decrease the incidence and severity of ball impact injuries to less skilled players aged 5-12, the USA Baseball Medical and Safety Advisory Committee recommends: 1. That youth baseball organizations adopt for their Tee-Ball and other “minor league” programs that are focused on skill development, reduced impact baseballs that meet NOCSAE standards levels 1 and 2.

2. This recommendation does not diminish the importance of teaching fundamental baseball skills and ball avoidance skills and techniques for batters.

3. Current scientific literature on the prevention of commotio cordis by chest protectors is not adequate and therefore, the effect of any equipment on the risk of chest impact death remains unsubstantiated at this time.“

 In My Opinion: I know from the ongoing injury study that I perform for my insurance client, Dixie Youth Baseball (ages 12 & under), that three of the leading causes of injury are being struck by batted balls, thrown balls, and pitched balls. The vast majority of injuries that occur in T Ball and Coach Pitch are from being struck by batted balls and thrown balls. These injuries in the lower age groups are primarily caused by lack of skills. Based on my personal observation in working with youth baseball players ages 5-8, players can better learn skills if some of the fear factor is removed. I would say that softer baseballs definitely remove some of the fear factor which can result in more quality practice sessions in terms of repetitions and the development of skills. As players move out of T Ball and Coach Pitch, the skill levels are usually such that the types of injuries that could theoretically be prevented or reduced by reduced impact balls don’t come into play as often. From an injury analysis point of view, it is almost impossible to predict if a reduced impact ball could have prevented or reduced an Accident insurance claim. It is much easier to predict the outcome of other safety equipment such as batter’s face guards or catcher’s throat protectors as they are almost 99% effective in preventing injury.
