Question: My daughter has minimal mitral and aortic regurgitation, for which she has no treatment. Would you like to know what caused them? Could they have been caused by a hiatus hernia that you also have? I also have aortic dilation for no apparent reason. Could it be something genetic? María (Pontevedra).
Answer: Indeed, some valve and aortic abnormalities have a genetic cause. In any case, what you tell about your daughter, that is, minimal aortic and mitral regurgitation, is a normal finding. This is so because all biological structures have a small margin of "error" in their operation.
