Medical specialty:  Cardiovascular / Pulmonary
 Sinus bradycardia, sick-sinus syndrome, poor threshold on the ventricular lead and chronic lead.  Right ventricular pacemaker lead placement and lead revision.

PROCEDURE: , Right ventricular pacemaker lead placement and lead revision.,INDICATIONS:,  Sinus bradycardia, sick-sinus syndrome, poor threshold on the ventricular lead and chronic lead.,EQUIPMENT: , A new lead is a Medtronic model #12345, threshold sensing at 5.7, impedance of 1032, threshold of 0.3, atrial threshold is 0.3, 531, and sensing at 4.1.  The original chronic ventricular lead had a threshold of 3.5 and 6 on the can.,ESTIMATED BLOOD LOSS: , 5 mL.,PROCEDURE DESCRIPTION:  ,Conscious sedation with Versed and fentanyl over left subclavicular area with pacemaker pocket was anesthetized with local anesthetic with epinephrine.  The patient received a venogram documenting patency of the subclavian vein.  Skin incision with blunt and sharp dissection.  Electrocautery for hemostasis.  The pocket was opened and the pacemaker was removed from the pocket and disconnected from the leads.  The leads were sequentially checked.  Through the pocket a puncture of the vein with a thin wall needle was made and a long sheath was used to help carry it along the tortuosity of the proximal subclavian and innominate superior vena cava.  Ultimately, a ventricular lead was placed in apex of the right ventricle, secured to base pocket with 2-0 silk suture.  Pocket was irrigated with antibiotic solution.  The pocket was packed with bacitracin-soaked gauze.  This was removed during the case and then irrigated once again.  The generator was attached to the leads, placed in the pocket, secured with 2-0 silk suture and the pocket was closed with a three layer of 4-0 Monocryl.,CONCLUSION:  , Successful replacement of a right ventricular lead secondary to poor lead thresholds in a chronic lead and placement of the previous Vitatron pulse generator model # 12345.
Nuclear Cardiac Stress Report 
Medical specialty:  Cardiovascular / Pulmonary
 Nuclear cardiac stress report.  Recurrent angina pectoris in a patient with documented ischemic heart disease and underlying ischemic cardiomyopathy.

NUCLEAR CARDIOLOGY/CARDIAC STRESS REPORT,INDICATION FOR STUDY: , Recurrent angina pectoris in a patient with documented ischemic heart disease and underlying ischemic cardiomyopathy.,PROCEDURE: , The patient was studied in the resting state following intravenous delivery of adenosine triphosphate at 140 mcg/kg/min delivered over a total of 4 minutes.  At completion of the second minute of infusion, the patient received technetium Cardiolite per protocol.  During this interval, the blood pressure 150/86 dropped to near 136/80 and returned to near 166/84 at completion.  No diagnostic electrocardiographic abnormalities were elaborated during this study.,REGIONAL MYOCARDIAL PERFUSION WITH ADENOSINE PROVOCATION: , Scintigraphic study reveals at this time multiple fixed defects in perfusion suggesting indeed multivessel coronary artery disease, yet no active ischemia at this time.  A fixed defect is seen in the high anterolateral segment.  A further fixed perfusion defect is seen in the inferoapical wall extending from close to the septum.  There is no evidence for active ischemia in either distribution.  Lateral wall moving towards the apex of the left ventricle is further involved from midway through the ventricle moving upward and into the high anterolateral vicinity.  When viewed from the vertical projection, the high septal wall is preserved with significant loss of the mid anteroapical wall moving to the apex and in a wraparound fashion in the inferoapical wall.  A limited segment of apical myocardium is still viable.,No gated wall motion study was obtained.,CONCLUSIONS:  ,Cardiolite perfusion findings support multivessel coronary artery disease and likely previous multivessel infarct as has been elaborated above.  There is no indication for active ischemia at this time.

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.
