The occurrence of atrial fibrillation is common in the setting of mitral stenosis. The left atrium is usually enlarged and scarred in this situation leading to the difficulty in treating AF. It is unlikely that a sinus infection could have caused AF. However if you have any doubts, then you can wait until the infection resolves and see if AF still reccurs.
SVT is usually a recurrent problem. Also in your situation it appears to have resulted in a very high heart rate leading to a rise I Troponin. SVT can be treated with medication or catheter ablation depending on the situation.
This Journal focuses on atrial fibrillation and its treatment. I suggest that you check with your cardiologist
