Cardiologist,  's  Response
Hello! Thank you for asknig on HCM! Regarding your concern, I would explain that a mechanical aortic valve may become narrow is two ways:
(1) thrombus formation, which may be evidenced as a not so echo dense mass by cardiac ultrasound, and in general is associated wit ha history of inadequate anticoagulation; and
(2) Pannus formation, which not rarely is not evidenced by standard transthoracic echocardiography, and is generally a late complication of mechanical valves.

Clinical, echacardiographic data are necessary to differentiate between these two entities.

Hope to have been helpful. Greetings! Dr. Iliri
