Normal Single Coronary Artery and Myocardial

چکیده
matoid disease on histologic evaluation of the pulmonary and subcutaneous lesions together. The pulmonary lesion had extensive fibrosis, as well as necrosis, and appeared to be a late relatively quiescent lesion. Angiitis was found within but not outside this lesion. Granulomatous infection was unlikely because cultures of the sputum and lung biopsy failed to grow mycobacterial or fungal organisms and because the pulmonary nodules slowly multiplied and enlarged over ten years without other evidence of localized or disseminated infection. Thus, although the findings in the lung alone were consistent with either Wegener's granulomatosis or a rheumatoid nodule, such late scarred lesions are best described as nondiagnostic; however, in combination with the subcutaneous lesion, we believe that the diagnosis of rheumatoid nodule is most appropriate for both lesions. We considered the possibility that our patient first developed limited Wegener's granulomatosis and later developed unrelated subcutaneous nodules and rheumatoid factor. The combination of rheumatoid disease and Wegener's granulomatosis has been reported previously in three c a ~ e s ; ~ ~ ~ ~ ~ however, all had arthritis, and none had pulmonary parenchymal lesions. Although we cannot exclude the above combination, the absence of typical vasculitis outside the scarred lesion in our patient's lung militates against it. Thus, we believe that our case represents the unusual development of pulmonary rheumatoid nodules over ten years in the absence of clinical features of rheumatoid arthritis.

Prediction of Changes in Left Ventricular Ejection Fraction after Off-Pump Coronary Artery Bypass Grafting Surgery by Myocardial Perfusion Single-Photon Emission Computed Tomography
Introduction: Left ventricular ejection fraction (LVEF) is considered to be the single most important prognostic factor in patients with previous myocardial infarction. LVEF is not improved in all patients after coronary artery bypass grafting (CABG). This study aimed to assess the possibility of prediction of LVEF changes after CABG using myocardial perfusion gated signle photon emission compu...
متن کاملMultiple myocardial bridge in a 59 year-old woman
Introduction: Myocardial bridging is a congenital condition in which a segment of a major epicardial coronary artery has an intra myocardial route. Myocardial bridging is usually confined to a single vessel and is typically the mid segment of the left anterior descending artery. Bridging may be associated with chest pain, myocardial infarction, and sudden cardiac death, or usually asymptomati...
متن کاملA Rare Case of Double Myocardial Bridges of the Left Anterior Descending Artery
Myocardial bridge is a benign congenital anomaly in which a segment of major epicardial coronary arteries descends into the myocardium for a variable distance. Myocardial bridge is most often single and located in the middle part of the left anterior descending artery. The presence of more than one myocardial bridge in coronary arteries is very rare. We present a patient with more than one myoc...

Introduction: Although coronary endarterectomy is not an ideal procedure, it is the only available option for cardiac surgeons in some patients with diffuse coronary artery disease. Based on the majority of conducted studies, the results of coronary endarterectomy (including survival, graft patency, and recurrence of the symptoms of myocardial ischemia) are less prevalent than standard coronary...
