Left Atrial Enlargement in Teenager
An_248217 posted:
My 16 year old son almost passes out at football practice in 100+ weather this week. We took him to the hospital and he was treated for dehydration. An EKG was performed and it showed a left atrial enlargement and further tests showed an increase in his Troponin l level. I am waiting to get in with a cardiologist for further testing but I am very anxious about what is going on. He has been a competitive athlete in multiple sports for the majority of his life. Should I be concerned that he may no longer be able to compete? Is he going to need surgery? See, I'm having a little anxiety.

Yes, of course.

"Is he going to need surgery?"

Not necessarily, though there is no way to truly tell/know for sure via the Internet (which has serious limitations/restrictions)

About Left Atrial Enlargement

As reported, causes of true (must be 100% confirmed, typically with non-invasive echocardiography/cardiac ultrasound) left atrial enlargement (LAE) or dilation include, but is not limited to, mitral valve regurgitation (leakage, a backflow of blood through the one way-only valve) or stenosis (narrowing).

Also, LAE often occurs with any cause of left ventricular hypertrophy (LVH), a thickening of the wall of the left ventricle (LV), the heart's high-pressure pumping chamber.

Most important, communicate/interact well with his doctors. Best of luck to your son down the road of life. May he live long and prosper.

Take care,
