“…The percentage of myocardial abscesses found on autopsy studies ranges from 0.18% in 1966 [3] to 1.52% reported in 1962 [4]. The most common cause of myocardial abscess is S. aureus , as was found in our patient.…”

“…The most common cause of myocardial abscess is S. aureus , as was found in our patient. Other common pathogens include Candida and various Gram-negative rods including Escherichia coli , Klebsiella pneumoniae , and Proteus vulgaris [4], although many pathogens have been implicated. Various disease states have been noted in association with bacterial myocarditis including alcoholic hepatitis [5, 6], acute myocardial infarction [5], malignancy [5, 6],acute osteomyelitis [7], and various surgical conditions [4, 6].…”

We report a case of an 81-year-old man with bacterial myocarditis presenting with elevated troponins and sepsis, who succumbed due to a ruptured ventricle. The infecting organism was found to be methicillin-resistant Staphylococcus aureus. Bacterial myocarditis is a rare occurrence when independent of infective endocarditis. Generally, this is a complication of bacteremia that is discovered post-mortem. Rarely, as in our patient, it causes significant necrosis of the myocardium leading to rupture of a ventricle. As with viral myocarditis, this disease can present with signs and symptoms of acute myocardial infarction, complicating the diagnosis. Much of the available data on bacterial myocarditis was collected before the development of many modern diagnostic tests and before antibiotics. Accordingly, the appropriate workup, diagnosis and treatment remain unclear. Our patient represents the first reported case of ventricular rupture due to methicillin-resistant S. aureus-associated bacterial myocarditis.

“…Bacterial myocarditis can be caused by many kinds of bacteria such as staphylococcus aureus, streptococcus, pneumococcus, and neisseria meningitidis. Although there are a few reports of urinary tract infections as the cause of bacterial myocarditis, 4) we suggest that urinary tract infection by E. coli might have caused myocarditis in this case, because E. coli was positive in both blood and urine cultures were positive for E. coli. The definitive diagnosis of bacterial myocarditis requires morphologically proven active myocarditis with evidence of bacterial invasion or positive tissue cultures.…”

Various Cardiac Abnormalities Caused by Bacterial Myocarditis

SummaryA 69-year-old woman without any past disease history was hospitalized for heart failure. After hospitalization, she showed myocardial infarction, atrioventricular dissociation, and cardiac dysfunction, and finally she passed away despite intensive care. Autopsy revealed that the cardiac abnormalities were due to bacterial myocarditis possibly resulting from urinary tract infection by E. coli. Although bacterial myocarditis is rare in developed countries, we should consider its possibility when patients show various cardiac abnormalities with bacterial infection.(Int Heart J 2018; 59: 229-232) Key words: Heart failure, Myocardial infarction, Atrioventricular dissociation M yocarditis induces various cardiac abnormalities including systolic dysfunction and arrhythmia. The most common cause of myocarditis in developed countries is the infection of viruses such as coxsackievirus, adenovirus, enterovirus, parvovirus B-19, parainfluenza viruses and human herpesvirus-6. 1,2) Although bacterial myocarditis was has been very rare in developed countries, 3) the number of patients with bacterial myocarditis has recently been increasing because of an increase in immunocompromised hosts. In most cases, bacterial myocarditis is suspected based on clinical test results, but few cases have been diagnosed while alive. We here present a patient who suddenly developed myocardial infarction, atrioventricular dissociation, and heart failure without any past disease history. Morbid anatomy revealed that the diagnosis was bacterial myocarditis. Here we describe the various clinical and pathological findings of this case and with some also discussions about bacterial myocarditis in general. Case ReportA 69-year-old woman visited our hospital because of death of her brother's death. While she was plunged in grief, she suddenly felt dyspnea. Approximately 2 weeks before, she had visited a local doctor because of wheezing and insomnia. Pleural effusion had been found by chest X-ray examination, and a diuretic had been prescribed. In our hospital, she had slight tachycardia (106/minute) but other physical findings, including blood pressure (118/64 mmHg) and body temperature (35.5 ), were normal (35.5 ). X-ray examination revealed bilateral pleural effusion and pulmonary congestion, and the electrocardiogram showed a negative T wave in I, aVL, and V3-6 leads. Routine blood examination revealed the elevation of C-reactive protein levels (4.8 mg 8 mg/dL) and white blood cell counts (13.9 × 10 3 /μL). Ultrasound echocardiography showed dilatation of the left ventricle (left ventricular dimension diastolic/systolic 60/51 mm), systolic dysfunction (ejection fraction 31%), mild aortic regurgitation, and moderate mitral regurgitation. The wall motion was diffusely reduced, and in particular, the wall motions of the inferior apex wall and the anterolateral wall were severely impaired. We diagnosed her as acute decompensated heart failure with unknown etiology and administered furosemide, carperitide and dobutamine. Since she had no fever a...

“…Myocardial abscess is found in 0.18-1.52% of all autopsies of adults. [1][2][3] We described the case of a chronic kidney disease patient who had been on hemodialysis and presented with myocardial abscess and pulmonary abscesses following the infection of a AVF. One of the first cases of myocardial abscess was described by Cossio and Berconsky in 1933, in an autopsy report describing a pneumococcal abscess in infarcted myocardial tissue.…”

“…In that study, the myocardial abscesses were small, raising the hypothesis that myocardial abscess is so severe that patients do not survive long enough for the abscess to increase in size. 1 A review of 63 autopsy reports showed the concomitant presence of myocardial abscess and abscesses in other organs in 81% of the cases. in the remaining 32.5%, myocardial abscess is associated with infective endocarditis of prosthetic valves.…”
