Myocardial Perfusion Imaging - 2  ( Cardiovascular / Pulmonary)
Description:  Myocardial perfusion imaging - patient had previous abnormal stress test.  Stress test with imaging for further classification of CAD and ischemia.

CLINICAL HISTORY: , This is a 64-year-old male patient, who had a previous stress test, which was abnormal and hence has been referred for a stress test with imaging for further classification of coronary artery disease and ischemia.,PERTINENT MEDICATIONS:,  Include Tylenol, Robitussin, Colace, Fosamax, multivitamins, hydrochlorothiazide, Protonix and flaxseed oil.,With the patient at rest 10.5 mCi of Cardiolite technetium-99 m sestamibi was injected and myocardial perfusion imaging was obtained.,PROCEDURE AND INTERPRETATION: , The patient exercised for a total of 4 minutes and 41 seconds on the standard Bruce protocol.  The peak workload was 7 METs.  The resting heart rate was 61 beats per minute and the peak heart rate was 173 beats per minute, which was 85% of the age-predicted maximum heart rate response.  The blood pressure response was normal with the resting blood pressure 126/86, and the peak blood pressure of 134/90.  EKG at rest showed normal sinus rhythm with a right-bundle branch block.  The peak stress EKG was abnormal with 2 mm of ST segment depression in V3 to V6, which remained abnormal till about 6 to 8 minutes into recovery.  There were occasional PVCs, but no sustained arrhythmia.  The patient had an episode of supraventricular tachycardia at peak stress.  The ischemic threshold was at a heart rate of 118 beats per minute and at 4.6 METs.  At peak stress, the patient was injected with 30.3 mCi of Cardiolite technetium-99 m sestamibi and myocardial perfusion imaging was obtained, and was compared to resting images.,MYOCARDIAL PERFUSION IMAGING:,1.  The overall quality of the scan was fair in view of increased abdominal uptake, increased bowel uptake seen.,2.  There was a large area of moderate to reduced tracer concentration seen in the inferior wall and the inferior apex.  This appeared to be partially reversible in the resting images.,3.  The left ventricle appeared normal in size.,4.  Gated SPECT images revealed normal wall motion and normal left ventricular systolic function with normal wall thickening.  The calculated ejection fraction was 70% at rest.,CONCLUSIONS:,1.  Average exercise tolerance.,2.  Adequate cardiac stress.,3.  Abnormal EKG response to stress, consistent with ischemia.  No symptoms of chest pain at rest.,4.  Myocardial perfusion imaging was abnormal with a large-sized, moderate intensity partially reversible inferior wall and inferior apical defect, consistent with inferior wall ischemia and inferior apical ischemia.,5.  The patient had run of SVT at peak stress.,6.  Gated SPECT images revealed normal wall motion and normal left ventricular systolic function.

Myoview Perfusion Scan  ( Cardiovascular / Pulmonary)
Description:  Resting Myoview perfusion scan and gated myocardial scan.  Findings consistent with an inferior non-transmural scar

INDICATIONS:,  Previously markedly abnormal dobutamine Myoview stress test and gated scan.,PROCEDURE DONE:,  Resting Myoview perfusion scan and gated myocardial scan.,MYOCARDIAL PERFUSION IMAGING:,  Resting myocardial perfusion SPECT imaging and gated scan were carried out with 32.6 mCi of Tc-99m Myoview.  Rest study was done and compared to previous dobutamine Myoview stress test done on Month DD, YYYY.  The lung heart ratio is 0.34.  There appears to be a moderate size inferoapical perfusion defect of moderate degree.  The gated myocardial scan revealed mild apical and distal inferoseptal hypokinesis with ejection fraction of 55%.,CONCLUSIONS:,  Study done at rest only revealed findings consistent with an inferior non-transmural scar of moderate size and moderate degree.  The left ventricular systolic function is markedly improved with much better regional wall motion of all left ventricular segments when compared to previous study done on Month DD, YYYY.  We cannot assess the presence of any reversible perfusion defects because no stress imaging was performed.

Mesothelioma - Pleural Biopsy  ( Cardiovascular / Pulmonary)
Description:  Right pleural effusion and suspected malignant mesothelioma.

PREOPERATIVE DIAGNOSIS: , Right pleural effusion and suspected malignant mesothelioma.,POSTOPERATIVE DIAGNOSIS:,  Right pleural effusion, suspected malignant mesothelioma.,PROCEDURE: , Right VATS pleurodesis and pleural biopsy.,ANESTHESIA:,  General double-lumen endotracheal.,DESCRIPTION OF FINDINGS: , Right pleural effusion, firm nodules, diffuse scattered throughout the right pleura and diaphragmatic surface.,SPECIMEN: , Pleural biopsies for pathology and microbiology.,ESTIMATED BLOOD LOSS: , Minimal.,FLUIDS: , Crystalloid 1.2 L and 1.9 L of pleural effusion drained.,INDICATIONS: , Briefly, this is a 66-year-old gentleman who has been transferred from an outside hospital after a pleural effusion had been drained and biopsies taken from the right chest that were thought to be consistent with mesothelioma.  Upon transfer, he had a right pleural effusion demonstrated on x-ray as well as some shortness of breath and dyspnea on exertion.  The risks, benefits, and alternatives to right VATS pleurodesis and pleural biopsy were discussed with the patient and his family and they wished to proceed.,PROCEDURE IN DETAIL:  ,After informed consent was obtained, the patient was brought to the operating room and placed in supine position.  A double-lumen endotracheal tube was placed.  SCDs were also placed and he was given preoperative Kefzol.  The patient was then brought into the right side up, left decubitus position, and the area was prepped and draped in the usual fashion.  A needle was inserted in the axillary line to determine position of the effusion.  At this time, a 10-mm port was placed using the knife and Bovie cautery.  The effusion was drained by placing a sucker into this port site.  Upon feeling the surface of the pleura, there were multiple firm nodules.  An additional anterior port was then placed in similar fashion.  The effusion was then drained with a sucker.  Multiple pleural biopsies were taken with the biopsy device in all areas of the pleura.  Of note, feeling the diaphragmatic surface, it appeared that it was quite nodular, but these nodules felt as though they were on the other side of the diaphragm and not on the pleural surface of the diaphragm concerning for a possibly metastatic disease.  This will be worked up with further imaging study later in his hospitalization.  After the effusion had been drained, 2 cans of talc pleurodesis aerosol were used to cover the lung and pleural surface with talc.  The lungs were then inflated and noted to inflate well.  A 32 curved chest tube chest tube was placed and secured with nylon.  The other port site was closed at the level of the fascia with 2-0 Vicryl and then 4-0 Monocryl for the skin.  The patient was then brought in the supine position and extubated and brought to recovery room in stable condition.,Dr. X was present for the entire procedure which was right VATS pleurodesis and pleural biopsies.,The counts were correct x2 at the end of the case.

Mediastinal Exploration & Right Atrium Repair  ( Cardiovascular / Pulmonary)
Description:  The patient had undergone mitral valve repair about seven days ago. 

PREOPERATIVE DIAGNOSES:,1.  Cardiac tamponade.,2.  Status post mitral valve repair.,POSTOPERATIVE DIAGNOSES:,1.  Cardiac tamponade.,2.  Status post mitral valve repair.,PROCEDURE PERFORMED: , Mediastinal exploration with repair of right atrium.,ANESTHESIA: , General endotracheal.,INDICATIONS: , The patient had undergone mitral valve repair about seven days ago.  He had epicardial pacing wires removed at the bedside.  Shortly afterwards, he began to feel lightheaded and became pale and diaphoretic.  He was immediately rushed to the operating room for cardiac tamponade following removal of epicardial pacing wires.  He was transported immediately and emergently and remained awake and alert throughout the time period inspite of hypotension with the systolic pressure in the 60s-70s.,DETAILS OF PROCEDURE:  ,The patient was taken emergently to the operating room and placed supine on the operating room table.  His chest was prepped and draped prior to induction under general anesthesia.  Incision was made through the previous median sternotomy chest incision.  Wires were removed in the usual manner and the sternum was retracted.  There were large amounts of dark blood filling the mediastinal chest cavity.  Large amounts of clot were also removed from the pericardial well and chest.  Systematic exploration of the mediastinum and pericardial well revealed bleeding from the right atrial appendix at the site of the previous cannulation.  This was repaired with two horizontal mattress pledgeted #5-0 Prolene sutures.  An additional #0 silk tie was also placed around the base of the atrial appendage for further hemostasis.  No other sites of bleeding were identified.  The mediastinum was then irrigated with copious amounts of antibiotic saline solution.  Two chest tubes were then placed including an angled chest tube into the pericardial well on the inferior border of the heart, as well as straight mediastinal chest tube.  The sternum was then reapproximated with stainless steel wires in the usual manner and the subcutaneous tissue was closed in multiple layers with running Vicryl sutures.  The skin was then closed with a running subcuticular stitch.  The patient was then taken to the Intensive Care Unit in a critical but stable condition.
Lung Biopsy Pathology Report  ( Cardiovascular / Pulmonary)
Description:  Lung, wedge biopsy right lower lobe and resection right upper lobe.  Lymph node, biopsy level 2 and 4 and biopsy level 7 subcarinal.  PET scan demonstrated a mass in the right upper lobe and also a mass in the right lower lobe, which were also identified by CT scan.

CLINICAL HISTORY:,  A 48-year-old smoker found to have a right upper lobe mass on chest x-ray and is being evaluated for chest pain.  PET scan demonstrated a mass in the right upper lobe and also a mass in the right lower lobe, which were also identified by CT scan.  The lower lobe mass was approximately 1 cm in diameter and the upper lobe mass was 4 cm to 5 cm in diameter.  The patient was referred for surgical treatment.,SPECIMEN:,A.  Lung, wedge biopsy right lower lobe,B.  Lung, resection right upper lobe,C.  Lymph node, biopsy level 2 and 4,D.  Lymph node, biopsy level 7 subcarinal,FINAL DIAGNOSIS:,A.  Wedge biopsy of right lower lobe showing:  Adenocarcinoma, Grade 2, Measuring 1 cm in diameter with invasion of the overlying pleura and with free resection margin.,B.  Right upper lobe lung resection showing:  Adenocarcinoma, grade 2, measuring 4 cm in diameter with invasion of the overlying pleura and with free bronchial margin.  Two (2) hilar lymph nodes with no metastatic tumor.,C.  Lymph node biopsy at level 2 and 4 showing seven (7) lymph nodes with anthracosis and no metastatic tumor.,D.  Lymph node biopsy, level 7 subcarinal showing (5) lymph nodes with anthracosis and no metastatic tumor.,COMMENT:  ,The morphology of the tumor seen in both lobes is similar and we feel that the smaller tumor involving the right lower lobe is most likely secondary to transbronchial spread from the main tumor involving the right upper lobe.  This suggestion is supported by the fact that no obvious vascular or lymphatic invasion is demonstrated and adjacent to the smaller tumor, there is isolated nests of tumor cells within the air spaces.  Furthermore, immunoperoxidase stain for Ck-7, CK-20 and TTF are performed on both the right lower and right upper lobe nodule.  The immunohistochemical results confirm the lung origin of both tumors and we feel that the tumor involving the right lower lobe is due to transbronchial spread from the larger tumor nodule involving the right upper lobe.,
