Abstract
Intramyocardial abscesses are rare in cattle and may lead to unspecific clinical signs. This case report describes the clinical and echocardiographic findings in an 8 year old Brown Swiss cow presented with an intramural myocardial abscess. The main clinical findings were anorexia, drop in milk yield, fever, tachycardia, and hyperfibrinogenemia. Neither heart murmurs nor cardiac arrhythmias were present on auscultation. Transthoracic echocardiographic examination revealed a prominent intramural mass embedded in the left ventricular free wall and bulging into the lumen of the left ventricle. Diagnosis was confirmed at necropsy. A culture of the abscess grew Trueperella pyogenes.

Abstract
Cardiac infections presenting as emergencies include complications of infective endocarditis, including congestive heart failure, chordae tendinae rupture, cardiac arrhythmias, and embolic phenomenon; acute pericarditis, including cardiac tamponade; and acute myocarditis presenting with malignant cardiac arrhythmias or congestive heart failure. Most of these emergent infectious disease manifestations of the cardiovascular system have a good prognosis if diagnosed early and managed appropriately. Newer diagnostic modalities and combined treatment guidelines are available from the European Society of Cardiology and the American Heart Association.

Abstract
We present a case of Staphylococcus aureus endocarditis in which a large abscess was formed in only 4 days, despite specific intravenous antibiotics and only few vague signs of disease progression. Our case seems to be the first to show echocardiographic documentation of how quickly an intracardiac abscess can develop despite relevant antibiotics. Clinically, the patient is remarkably unaffected, and thus even small signs of progression should lead to considerations about repeating the diagnostic imaging workup. This case illustrates how aggressive an infection S. aureus endocarditis may be, and therefore it should be treated by an experienced team with easy access to both transthoracic and transesophageal echocardiography.

Abstract
Myocardial abscess perforation is an extremely rare complication of infective endocarditis. We present a case of a 12-month-old infant who developed community-associated methicillin-resistant Staphylococcus aureus bacteremia after an incision and drainage of a skin abscess. He subsequently developed septic emboli to the brain and lungs, and a myocardial cavity in the outlet portion of the interventricular septum. The cavity ruptured 4 days after diagnosis and created a left ventricle to pulmonary artery fistulous communication. The patient died secondary to embolic complications to the brain. We are not aware of any other cases of myocardial abscess rupture in this location of the heart, in a patient of this age, or due to infection with community-associated methicillin-resistant S aureus .

Abstract
The current study is the first scientometric analysis of research activity and output in the field of inflammatory disorders of the heart (endo-, myo- and pericarditis). Scientometric methods are used to compare scientific performance on national and on international scale to identify single areas of research interest. Interest and research productivity in inflammatory diseases of the heart have increased since 1990. The majority of publications about inflammatory heart disorders were published in Western Europe and North America. The United States of America had a leading position in terms of research productivity and quality; half of the most productive authors in this study came from American institutions. The analysis of international cooperation revealed research activity in countries that are less established in the field of inflammatory heart disorder research, such as Brazil, Saudi Arabia and Tunisia. These results indicate that future research of heart inflammation may no longer be influenced predominantly by a small number of countries. Furthermore, this study revealed weaknesses in currently established scientometric parameters (i.e., h-index, impact factor) that limit their suitability as measures of research quality. In this respect, self-citations should be generally excluded from calculations of h-index and impact factor.

Abstract
INTRODUCTION Myocardial abscess is a rare and potentially fatal condition. Metastatic myocardial abscess in the setting of infective endocarditis has been infrequently reported in the medical literature. To the best of the authors' knowledge no case of myocardial abscess affecting the free wall of the left ventricle secondary to infective endocarditis of a right-sided heart valve has been reported previously. CASE PRESENTATION We report a case of tricuspid valve endocarditis caused by Staphylococcus aureus and resulting in a myocardial abscess on the posterior wall of the left ventricle, far from the active valvular infection. We also briefly discuss the role of different investigation modalities including cardiac magnetic resonance imaging in diagnosing myocardial abscess. CONCLUSION Myocardial abscess is a life-threatening illness. A high index of clinical suspicion is required to make a prompt diagnosis. Final diagnosis may need multi-modality imaging. An early diagnosis, aggressive medical therapy, multidisciplinary care and timely surgical intervention may save life in this otherwise fatal condition.

Abstract
Myocardial abscess formation is a life-threatening complication that is frequently but not exclusively associated with infective endocarditis. To our knowledge there are only two case reports of myocardial abscess formation in hemodialysis patients. Only one of these reports describes a myocardial abscess of bacterial etiology secondary to an infected intravascular hemodialysis catheter. Furthermore, there are no reports of bacterial myocardial abscess occurring in a hemodialysis patient with an infected arteriovenous fistula. Myocardial abscess can manifest in a variety of clinical scenarios ranging from an asymptomatic state to a catastrophic myocardial wall rupture. In the case described, the myocardial abscess lead to a rapidly progressive course consisting of recurrent cardiac arrhythmias that were ultimately fatal. Our case involved the formation of a myocardial abscess in the presence of a methicillin-resistant Staphylococcus aureus bacteremia without any evidence of infective endocarditis. We report this case to call attention to the possibility of bacterial myocardial abscess occurring with infection of an arteriovenous fistula in a hemodialysis patient, which can manifest as recurrent severe cardiac arrhythmias refractory to medical therapy.
