 Medical Report: allergies: no known allergies / adverse drug reactions attending: chief complaint: dyspnea on exertion major surgical or invasive procedure: 1. coronary artery bypass grafting x2, left internal mammary artery graft to left anterior descending, reverse saphenous vein graft to the right coronary artery. 2. aortic valve replacement, . medical biocor tissue. history of present illness: 74 yo male followed for several years with serial echocardiograms for aortic stenosis. he has slowly developed some dyspnea on exertion. most recent echocardiogram showed confirmed aortic stenosis. he underwent a cardiac cath in preparation for aortic valve surgery which revealed two vessel disease. past medical history: aortic stenosis history of transient atrial fibrillation (not on coumadin) hypertension history of pericarditis cataract surgery social history: race: caucasian last dental exam: 6 months ago lives with: wife occupation: retired tobacco: quit at age 27 etoh: 1 beer/night family history: non-contributory physical exam: pulse: 51 resp: 18 o2 sat: 98% b/p right: 128/71 left: 132/69 height: 6'0" weight: 195 lbs general: well-developed male in no acute distress skin: warm dry intact heent: ncat perrla eomi neck: supple full rom chest: lungs clear bilaterally heart: rrr irregular murmur 3/6 systolic murmur abdomen: soft non-distended non-tender bowel sounds + extremities: warm , well-perfused edema -
