RESUMEN
AIMS: Echocardiographic assessment of cancer-associated non-bacterial thrombotic endocarditis (Ca-NBTE) is limited to case reports and small clinical series. The study aimed to identify heart valve abnormalities and its relation to embolic complications and cancer types. METHODS AND RESULTS: Manual review of echocardiographic images and medical records of Mayo Clinic patients (31 March 2002-30 June 2022) was performed. Ca-NBTE in 111 patients (mean age 63.2 ± 9.7 years, 66.7% female) predominantly affected mitral valves (MV) (69), 56 aortic (AV), 8 tricuspid (TV), and rarely pulmonic (PV) (1). In 18 patients, 2 valves were involved, 3 and 4 valve involvement in only a single patient each. Embolic complications were prevalent (n = 102, 91.9%). Ca-NBTE affected MV more frequently on the upstream (atrial) (90% vs. 49.3%) and TV downstream (ventricular) side (75% vs. 37.5%). NBTE size (cm) varied significantly among valves, with TV hosting the largest masses (0.63-2.40 × 0.39-1.77), compared with MV [(0.11-1.81 × 0.11-1.62), (length P = 0.001; width P = 0.03)] and AV [(0.20-2.70 × 0.11-1.51), (length P = 0.001; width P = 0.056)]; MV masses were borderline longer in systemic compared with cerebral emboli (P = 0.057). Majority of MV (79.6%) and AV (69.6%) had thickened leaflets. NBTE lesions commonly affected closing margins (73.9% MV, 85.7% AV, and 62.5% of TV) but rarely commissures of MV (8.7%), yet fairly frequently of AV (41.1%). Five patients had severe regurgitation of MV and 5 AV. CONCLUSION: Ca-NBTE manifests mainly as thrombotic mobile masses attached to thickened MV and AV, with distinct variations in size based on valve type. Embolic destination but not cancer type is associated with NBTE mass size and location.

Nonbacterial thrombotic endocarditis (NBTE) is a manifestation of prothrombotic status observed in patients with malignancy. Most cases are discovered only in the advanced stages. However, cancer in early stages may also induce NBTE development. We herein report an 87-year-old man with NBTE with multiple thromboembolization coexisting with lung cancer in early clinical stage. Autopsy findings revealed platelet- and fibrin-rich vegetations in both the tricuspid and mitral valves without evidence of bacterial infection. NBTE should be considered in cases with occult thromboembolization. Not only the presence of typical vegetation but irregular leaflet thickening should be monitored with careful echocardiographic examinations.

Non-bacterial thrombotic endocarditis, characterised by sterile vegetations, is commonly caused by systemic lupus erythematosus and is known to be complicated with embolic cerebrovascular disease. Embolic myocardial infarction with non-bacterial thrombotic endocarditis is extremely rare. We report a case of ventricular fibrillation arrest from presumed coronary embolisation in non-bacterial thrombotic endocarditis. While there are no standardised guidelines on the management of embolic myocardial infarction in endocarditis, it requires a multidisciplinary approach unique for every encountered clinical scenario.

Non-bacterial thrombotic endocarditis is mainly associated with malignancies and rheumatological diseases. We report the case of mildly symptomatic COVID-19 infection with non-bacterial aortic valve vegetation complicated by transient ischemic attack (TIA) and pulmonary embolism during his hospitalisation. This case emphasised rare life-threatening complications from a hypercoagulable state related to COVID-19 infection. To the best of our knowledge, this is the third case report of non-bacterial endocarditis in a patient with COVID-19 patients as a potential rare complication of COVID-19.

RATIONALE: Few isolated case reports and case series have reported arterial and venous thromboembolism related to adenomyosis; however, the underlying mechanism remains unclear. PATIENT CONCERNS: A 47-year-old woman presented with dizziness, nausea, vomiting, and loss of consciousness after red blood cell transfusion. She was being treated for menorrhagia and severe anemia. DIAGNOSES: Magnetic resonance imaging showed multiple infarctions in right cerebellum and bilateral frontal, parietal, and occipital lobes. Echocardiography performed during the evaluation for the source of emboli revealed multiple echogenic masses on the tricuspid aortic valve. There was no evidence of infection, and the masses on the aortic valve were diagnosed as nonbacterial thrombotic endocarditis. The levels of autoimmune antibodies and tumor markers except for carbohydrate antigen 19-9 and cancer antigen 125 were within the normal range. Uterine ultrasound showed a large adenomyosis. The patient was diagnosed with multiple cerebral and cerebellar infarctions due to nonbacterial thrombotic endocarditis, and hormone therapy and anticoagulation with warfarin were initiated. INTERVENTIONS: The patient did not develop recurrent infarction during anticoagulant therapy; however, menorrhagia worsened requiring total hysterectomy. OUTCOMES: The patient did not experience recurrent infarction despite the absence of anticoagulant therapy during the 3-year follow-up period. LESSONS: The present case adds to the limited number of previously reported cases and supports that, albeit rare, adenomyosis can be associated with embolic infarction and suggests that nonbacterial thrombotic endocarditis might be the link between adenomyosis and embolic infarction.

Non-bacterial thrombotic endocarditis (NBTE), also known as Libman-Sacks, marantic, thrombotic, or verrucous endocarditis, is a form of non-infective endocarditis that affects cardiac structures in patients who have predisposing underlying conditions.1 As it is rarely encountered in routine clinical practice, the condition may be overlooked or misdiagnosed. On the other hand, other similar clinical entities might be erroneously labeled as NBTE. Notwithstanding its ostensibly uncommon appearance in clinical practice, our understanding of NBTE has been expanding, especially with the advent of modern and advanced diagnostic tools that facilitate the evaluation process. Herein, we provide a comprehensive review of NBTE, with a focus on the contemporary diagnostic evaluation and management.

We describe a 39-year-old man referred for surgical aortic valve replacement for severe symptomatic aortic stenosis. Intraoperative inspection was unexpectedly consistent with marantic endocarditis. Pathology confirmed nonbacterial thrombotic endocarditis. We present high-resolution intraoperative, diagnostic, and pathology images of nonbacterial thrombotic endocarditis in a patient with antiphospholipid syndrome with atypical presentation.

Described herein is a 48-year-old woman with metastatic ovarian cancer who developed aortic regurgitation considered clinically to be the result of infective endocarditis but operative resection of the three aortic valve cusps disclosed the valve lesions to be typical of non-bacterial thrombotic endocarditis (NBTE). Aortic regurgitation as a consequence of NBTE is rare but at least 9 cases have been reported previously.

A 69-year-old Chinese man presented with exertional dyspnoea and subjective left upper limb weakness. Initial clinical impressions were community-acquired pneumonia and cerebrovascular accident. Further imaging studies revealed an incidental mitral valve vegetation and left lung upper lobe nodule likely a lung malignancy with possible lymphangitis carcinomatosis. Appropriate empirical antibiotic treatment for infective endocarditis was instituted early in admission, but multiple blood cultures were negative. The patient progressively developed worsening neurological dysfunction and subconjunctival haemorrhage from recurrent embolic complications despite empirical antimicrobial treatment. Histology finally revealed lung adenocarcinoma after delay in obtaining biopsy due to high procedural risk from recurrent stroke. Unfortunately, before the patient could undergo any systemic oncology treatment, he deteriorated with type I respiratory failure from obstructive pneumonia and eventually demised. Important lessons include the need to consider non-bacterial thrombotic endocarditis as a differential in the appropriate clinical context followed by anticoagulation with systemic treatment as early as possible.

A 66-year-old Caucasian man was initially admitted with a metastatic small cell lung carcinoma, hyponatraemia and obstructive pneumonia. His transthoracic echocardiogram (TTE) was normal. Ten days after admission, he was diagnosed with a non-ST segment elevation myocardial infarction (MI). Both a repeated TTE and a transoesophageal echocardiogram identified thickened, myxomatous mitral valve leaflet tips with small, mobile masses identified as vegetations, and new, eccentric, severe mitral regurgitation. Subsequent cardiac catheterisation recorded thrombotic occlusion of the right coronary artery. Successful coronary thrombectomy was carried out, but the patient died. A diagnosis of non-bacterial thrombotic endocarditis leading to coronary embolisation and MI was made. The clinical course and treatment choices are discussed.
