mid anterior - normal; basal anteroseptal - normal; mid anteroseptal - normal; basal inferoseptal - normal; mid inferoseptal - normal; basal inferior - normal; mid inferior - normal; basal inferolateral - normal; mid inferolateral - normal; basal anterolateral - normal; mid anterolateral - normal; anterior apex - normal; septal apex - normal; inferior apex - normal; lateral apex - normal; apex - normal; right ventricle: normal rv chamber size and free wall motion. aorta: normal aortic root diameter. normal ascending aorta diameter. normal descending aorta diameter. simple atheroma in descending aorta. aortic valve: severely thickened/deformed aortic valve leaflets. severe (4+) ar. mitral valve: mildly thickened mitral valve leaflets. trivial mr. tricuspid valve: mildly thickened tricuspid valve leaflets. mild tr. pulmonic valve/pulmonary artery: physiologic (normal) pr. pericardium: no pericardial effusion. general comments: a tee was performed in the location listed above. i certify i was present in compliance with hcfa regulations. no tee related complications. the tee probe was passed with assistance from the anesthesioology staff using a laryngoscope. the patient was under general anesthesia throughout the procedure. conclusions: pre-cpb: no spontaneous echo contrast is seen in the left atrial appendage. left ventricular wall thicknesses and cavity size are normal. no masses or thrombi are seen in the left ventricle. right ventricular chamber size and free wall motion are normal. there are simple atheroma in the descending thoracic aorta. the aortic valve leaflets are severely thickened/deformed. severe (4+) aortic regurgitation is seen. there is fusion of the right and non-coronary cusps, creating functionally a bicuspic valve. the mitral valve leaflets are mildly thickened. trivial mitral regurgitation is seen. the tricuspid valve leaflets are mildly thickened. there is no pericardial effusion. post-cpb: a prosthetic aortic valve is seen in place with no ai and no leaks. good biventricular systolic fxn. aorta intact. other parameters as pre-bypass. electronically signed by , md on 15:28. brief hospital course: this pt. was transferred from on for cardiac surgery. he had carotid studies which were negative and had a foley placed for urinary retention. he had a dental consult which revealed 2 teeth which required extraction prior to surgery. on he had teeth #7 and 21 extracted. on he had an avr with a 23mm st. mechanical valve with a cross clamp time of 63 mins. and a total bypass time of 79 mins. he tolerated the procedure well and was transferred to the csru in stable condition on neo and propofol. he was extubated on the post op night and had his chest tubes d/c'd on pod#1. he was transferred to the floor on pod#1 and had his epicardial pacing wires d/c'd on pod#2. he was then anticoagulated with heparin and coumadin and was discharged to home in stable condition on pod#6. he will have his inr drawn on and the results will be called to dr. . medications on admission: atenolol 50 mg po daily hctz 25 mg po daily discharge medications: 1. docusate sodium 100 mg capsule sig: one (1) capsule po bid (2 times a day). disp:*60 capsule(s)* refills:*2* 2. atorvastatin 10 mg tablet sig: one (1) tablet po daily (daily). disp:*90 tablet(s)* refills:*2* 3. oxycodone-acetaminophen 5-325 mg tablet sig: 1-2 tablets po every 6-8 hours as needed for pain. disp:*50 tablet(s)* refills:*0* 4. metoprolol tartrate 25 mg tablet sig: one (1) tablet po bid (2 times a day). disp:*60 tablet(s)* refills:*2* 5. furosemide 20 mg tablet sig: one (1) tablet po twice a day for 5 days. disp:*10 tablet(s)* refills:*0* 6. potassium chloride 10 meq capsule, sustained release sig: two (2) capsule, sustained release po twice a day for 5 days. disp:*20 capsule, sustained release(s)* refills:*0* 7. warfarin 5 mg tablet sig: one (1) tablet po once a day for 2 days: then inr check on , and continued dosing by dr. . disp:*60 tablet(s)* refills:*0* discharge disposition: home with service facility: discharge diagnosis: aortic insufficiency - s/p avr, hypertension discharge condition: good discharge instructions: patient may shower, no baths. no creams, lotions or ointments to incisions. no driving for at least one month. no lifting more than 10 lbs for at least 10 weeks from the date of surgery. monitor wounds for signs of infection. please call with any concerns or questions. followup instructions: cardiac surgeon, dr. in weeks - call for appt. local pcp, . in weeks - call for appt. local cardiologist, dr. in weeks - call for appt. procedure: extracorporeal circulation auxiliary to open heart surgery open and other replacement of aortic valve other surgical extraction of tooth continuous intra-arterial blood gas monitoring diagnoses: coronary atherosclerosis of native coronary artery unspecified essential hypertension aortic valve disorders retention of urine, unspecified periapical abscess without sinus
