Hello! Thank you for asking on HCM! Regarding your concern, I would explain that when facing with a mild mitral valve disease, the first strategy is to check about its possible adverse implications on cardiac structure and function, as well as on the overall daily physical performance. The best tool to arrive to a satisfactory follow up is by echocardiography performed on a scheduled repeated regimed. If it is a stenotic, regurgitant or any other congenital mitral valve disease, the underlying recommendations will be specific on when to proceed to surgery (reparative or valve replacement. Relyng on your actual physical status and echocardiography would be appropriate for guiding therapy. If you could provide all the medical recording, cardiac ultrasaound, angiography, etc, I could give a direct professional opinion. Hope to have been helpful! Feel free to ask me whenever you need! You can ask me directly. greetings! Dr. Iliri
