No, you do not have to worry about trivial regurgitation. Regurgitation is classified as: none, trace/trivial, mild, moderate and severe. Mild or less is no problem, does not give symptoms and normally does not need monitoring at all.
Trivial leakage does not cause hypoxia. Repair, if possible at all, will not help you and you wont find a cardiologist willing to do surgery for that.
Many people have mild or trivial regurgitation in one or more of their heart valves, often from birth and stable during their whole life.
