1/43. Tc-99m HDP uptake in cardiac amyloidosis.

    amyloidosis is characterized by the soft-tissue deposition of amyloid protein. It may occur as a primary disorder but more often is seen as a manifestation of chronic illness. Scattered reports of the affinity of amyloid for bone scanning agents have appeared over many years. Isolated cardiac uptake of Tc-99m HDP is described in a patient with biopsy-proved cardiac amyloidosis on a background of tuberculosis, prostate cancer, and coronary artery disease.

2/43. Rescue revascularization for acute coronary occlusion late after radiotherapy.

    Because radiation-induced coronary artery stenoses are frequently severe and located proximally, some patients are admitted in emergency. This report describes the case of a 47-year-old woman with radiation-induced stenosis of the left main coronary artery who presented with cardiac arrest during angiography. The patient was successfully treated using circulatory assistance and percutaneous transluminal coronary angioplasty as a bridge to coronary artery bypass grafting.

3/43. Directional coronary atherectomy for the diagnosis and treatment of radiation-induced coronary artery stenosis.

    While radiation therapy has been known to cause myocardial and pericardial damage, its role in accentuating coronary artery disease in the absence of traditional cardiovascular risk factors has been controversial. As younger patients with treatable cancers are being treated with mediastinal radiation, coronary artery disease as a cause for severe chest pain should be entertained as a possible diagnosis. We describe a 25-year-old male who presented with an inferior wall myocardial infarction 6 years after receiving mediastinal radiation and chemotherapy for Hodgkin's disease. He was subsequently treated by directional atherectomy to a 95% lesion in the right coronary artery. Histological examination of the atherectomy specimen revealed evidence of radiation-induced endothelial damage that had resulted in plaque formation and subsequent ischemia. Possible mechanisms for radiation-induced coronary artery disease and treatment options are discussed.

4/43. Mediastinal irradiation: A risk factor for atherosclerosis of the internal thoracic arteries.

    Previous radiotherapy to the thorax is a risk factor for coronary artery disease. patients with radiation-induced atherosclerosis tend to be young and frequently have lesions involving the coronary ostia and left anterior descending artery. Bypass is often the most suitable method of revascularization, and given the young age of the patient, arterial conduits would be considered superior to vein grafts. However, the internal thoracic arteries can lie within the radiation field and may not be free of atherosclerosis. A 40-year-old man who required coronary artery bypass grafting for multivessel coronary artery disease 11 years following radiotherapy for Hodgkin's lymphoma is reported. Preoperative angiography showed that the right internal thoracic artery had significant atherosclerosis and was unsuitable as a conduit.

5/43. Coronary spasm during outpatient fiberoptic laser bronchoscopy.

    A 63-year-old woman with metastatic breast cancer was referred to our bronchoscopy unit for outpatient laser resection of an endobronchial mass through fiberoptic bronchoscopy. The patient had no history of ischemic heart disease. During the procedure, the patient developed an ST-segment elevation and a complete atrioventricular block. IV nitroglycerin and morphine were effective in treating this episode. In this patient, we were able to demonstrate a focal spasm by postbronchoscopy coronary angiography.

6/43. The significance of incidental noncardiac findings in Tc-99m sestamibi myocardial perfusion imaging: illustrated by a case.

    technetium 99m sestamibi is widely used in the evaluation of myocardial perfusion imaging. Although the aim of such imaging is cardiac evaluation, numerous other organs are included in the imaging field. Failure to identify incidental abnormal findings in these organs delays diagnosis and treatment. In common with other radiopharmaceutical agents, technetium 99m sestamibi is distributed throughout the body and accumulates in multiple tissues. When interpreting studies that involve this radiotracer, the physician must be aware of its physiologic distribution, in order to recognize abnormal uptake. We present an illustrative case in which areas of decreased tracer activity were noted incidentally during the evaluation of unprocessed single photon emission computed tomography data. These findings were due to metastasis of colon cancer to the liver.

7/43. tobacco and public health.

    OBJECTIVES: An interactive program for physicians and surgeons was used to focus their attention on current issues of lung cancer in the united states. The issues examined were the risks for the development of lung cancer in smokers, spouses of smokers, recipients of second-hand or sidestream smoke, and the appropriate workup and treatment of patients with lung cancer. DESIGN: Case presentation with interactive questions and answers. patients: Six patients are presented whose cases demonstrate issues that are relevant and timely to the practice of thoracic surgery and oncology Interventions: Treatment for the five case presentations is used for interactive teaching purposes. CONCLUSIONS: lung cancer is epidemic in the united states, particularly among women at the present time. Physician awareness of the environmental and other factors contributing to the disease should stay current with the population variables that we are seeing in clinical practice.

8/43. Concomitant aortic root remodeling and coronary bypass in a patient with poor left ventricular function.

    A 58-year-old man who had previously undergone rectal cancer surgery and who had poor left ventricular function underwent concomitant aortic root remodeling and coronary bypass for aortic root aneurysm with aortic regurgitation and severe coronary artery disease. Intermittent retrograde cold blood cardioplegia and leukocyte-depleted terminal blood cardioplegia were used for myocardial protection. Angiographic studies 1 month after surgery showed improved left ventricular function at an ejection fraction from 24 to 46%. During a 1-year follow-up, he has remained free of any cardiac event. Even though this report is limited to a case and follow-up, this technique is expected to be beneficial even in patients with severely depressed left ventricular function when the postoperative quality of life is considered.

9/43. captopril-associated cholestasis complicating the management of pancreatic cancer.

    Cholestatic jaundice is a rare complication associated with the use of the angiotensin -converting enzyme inhibitor captopril. The severity of the disease may range from cholestasis on liver histology to overt fulminant hepatic failure. This diagnosis is seldom considered in patients with pancreatic or biliary tract malignancy. We present a patient with unresectable adenocarcinoma of the pancreas whose jaundice decreased slowly over many weeks despite establishment of adequate endoscopic biliary drainage. The presence of captopril-associated cholestasis confounded confirmation of adequate biliary drainage. The absence of observed hepatic bile secretion at duodenoscopy, as seen in this patient, is a previously unreported endoscopic feature of this syndrome.

10/43. Minimally invasive surgery for lung cancer with coronary artery disease.

    We report a 69-year-old woman with lung cancer and severe stenosis in the left anterior descending coronary artery. To perform a curative operation for the lung cancer without myocardial infarction, minimally invasive direct coronary artery bypass and left lower lobectomy with video-endoscopic assistance were performed simultaneously. There was no major complication, and she was discharged at 14 days after the operation. This procedure may be useful and safe for patients with lung cancer and coronary artery disease.
