Eustachian valve endocarditis

Eustachian Valve Endocarditis in a Patient With Charcot-Marie-Tooth Disease

Endocarditis is a serious infectious disease of the endocardial surface of the heart, predominantly involving the heart valves, and it results from the colonization and proliferation of microorganisms within the bloodstream. The condition primarily affects individuals with underlying cardiac abnormalities or those who have undergone invasive procedures. Symptoms may include pyrexia, fatigue, arthralgia, and new cardiac murmur. We present a case of a young male patient who had recently undergone surgery and developed eustachian valve endocarditis (EVE), a condition scarcely described in the literature.

Thoracic Osteomyelitis and Eustachian Valve Endocarditis: A Case Report and Literature Review

Infective endocarditis and vertebral osteomyelitis are rare infections, most commonly caused by methicillin-sensitive Staphylococcus aureus (MSSA). The eustachian valve is an embryological remnant of the inferior vena cava that has the potential to harbor a nidus leading to infective endocarditis. Eustachian valve endocarditis has been documented in the literature on less than 50 occasions and has yet to be documented in the presence of concomitant vertebral osteomyelitis. In this case, we present a 43-year-old male presenting with vertebral osteomyelitis caused by methicillin-resistant Staphylococcus aureus (MRSA). Persistent bacteremia prompted the identification of vegetative growth on a eustachian valve remnant. This case helps mend the gap in the literature by documenting the treatment considerations in a patient with eustachian valve endocarditis in the presence of osteomyelitis caused by MRSA.

Right-Sided Infective Endocarditis 2020: Challenges and Updates in Diagnosis and Treatment

Compared with the extensive data on left-sided infective endocarditis (IE), there is much less published information on the features and management of right-sided IE. Right-sided IE accounts for 5% to 10% of all IE cases, and compared with left-sided IE, it is more often associated with intravenous drug use, intracardiac devices, and central venous catheters, all of which has become more prevalent over the past 20 years. In this manuscript on right-sided IE we provide an up-to-date overview on the epidemiology, etiology, microbiology, potential locations of infection in the right heart, diagnosis, imaging, common complications, management, and prognosis. We present updated information on the treatment of pacemaker and device infections, infected fibrin sheaths that appear to be an easily missed source of infection after central line as well as pacemaker removal. We review current data on the AngioVac percutaneous aspiration device, which can obviate the need for surgery in patients with infected pacemaker leads and fibrin sheaths. We also focused on advanced diagnostic modalities, such as positron emission tomography/computed tomography. All of these are supported by specific case examples with detailed echocardiographic imaging from our experience.
