Bacterial Endocarditis and Mural Thrombi

چکیده
EMBOLIC phenomena occur with such frequency in the course of bacterial endocarditis as to constitute a cardinal diagnostic feature of this disease. However, it has been noted that the resultant infarcts are less often septic than would be expected if the emboli originated from the infected valvular vegetations.' A previous study of this apparent paradox showed that it is the nonbacterial thrombotic vegetation that is a frequent source of these emboli in patients with rheumatic heart disease with or without superimposed bacterial endocarditis.2 An incidental feature of this analysis, further substantiating the above findings, was the relative rarity of mural thrombi as the origin of such bland emboli in the cases of bacterial endocarditis. Another report also indicated the relative infrequency of severe mitral stenosis with bacterial endocarditis as well as the greater rarity of auricular fibrillation in patients with bacterial endocarditis.3 The role of each of these factors in the formation of mural thrombi in the left auricle has been discussed previously.4 A perusal of the recent literature discloses few references dealing specifically with this subject. Garvin5 in a study of mural thrombi in the heart found only 1 instance of mural thrombus in 30 cases of subacute bacterial endocarditis (3.3 per cent) and none in 13

Giant right ventricular mural vegetation mimicking a cardiac tumour.
Mural vegetations in the course of infective endocarditis are very rare. We report the case of a patient with an extremely large right ventricular free wall vegetation. Establishing diagnosis in the presence of only mural vegetations on echocardiography scan without valve involvement in the inflammatory process was difficult. In a differential diagnosis, benign and malignant tumours, metastases...

M yocardial infarction secondary to coronary embolization is infrequently encountered. Approximately 100 cases have l)een reported with the majority being associated with bacterial endocarditis or syphilis.’ Other causes are paradoxic embolization from atrial or ventricular mural thrombi, avulsed tissue or tumor2 and mitral stenosis with atrial fibrillation. a Coronary embolization has also bee...
متن کاملSuccessful treatment of left atrial auricular abscess.
Mural endocarditis causing myocardial abscess without valvular involvement is very rare. We report an unusual case of left atrial auricular abscess which was successfully treated by surgical resection, treatment with antibiotics, and mediastinal irrigation. A 9-yr-old female patient with previous history of urinary tract infection was admitted because of persistent fever. Echocardiography and m...
