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: no known allergies / adverse drug reactions attending: chief complaint: mitral regurgitation major surgical or invasive procedure: - mitral valve repair (34mm annuloplasty ring) history of present illness: this 62 year old gentleman with no signficant past medical history has had a heart murmur for most of his life. he was diagnosed with mitral valve prolapse and regurgitation 3 years ago. at that time he began to be followed with serial echocardiograms. his mitral regurgitation has worsened over time with his most recent echo showing severe mitral regurgitation with partial flail of anterior mitral leaflet. given the severity of his mitral valve regurgitation he has been referred for surgical management. he denies any symptoms of exertional dyspnea, fatigue, chest pain,orthopnea or palpitations. past medical history: mitral valve prolapse/regurgitation undescended testicle -
