Consider the following medical report that includes the patient's historical health records. Use it to predict the disease that the patient is high likely exposed to. 

 Medical Report: allergies: patient recorded as having no known allergies to drugs attending: chief complaint: dyspnea on exertion major surgical or invasive procedure: : procedure: aortic valve replacement with a 23-mm magna aortic valve bioprosthesis model number 3300tfx, serial number . history of present illness: this is a 59 year old female with known heart murmur since she was a child. her most recent echocardiogram revealed severe aortic stenosis. she does admit to some mild dyspnea on exertion, occasional dizziness and worsening fatigue. given the above echo findings, she has been referred for surgical management. she currently denies chest pain, syncope, pedal edema, orthopnea and pnd. past medical history: pmh: - aortic stenosis - hepatitis c, two biopsies in past have not shown any fibrosis. - hypertension - hypothyroidism - obesity - bronchial asthma - gerd, improved symptoms with diet change - depression, anxiety psh: -
