Cardiac Metastases from Choroidal Melanoma.

In patients with uveal melanoma, cardiac metastases can present without any symptoms. It is becoming more common than previously thought and highlights the importance of routine surveillance after definitive treatment.

Endomyocardial fibrosis in a non-tropical patient who presented with chest pain mimicking ACS and left ventricular thrombus, case report.

Endomyocardial fibrosis (EMF) is a disease known to cause restrictive cardiomyopathy. It shows a high prevalence in tropical countries. Several triggering factors have been proposed. However, the pathogenesis is still a mystery. The disease is progressive, and the outcome is generally unfavorable. The most common symptom is heart failure. However, an atypical presentation may be expected. Our case presented with symptoms suggestive of ischemia and missed diagnosis initially as ischemic cardiomyopathy. This report aims to increase the attention and awareness of this disease. We present a case of a 53-year-old man referred to the emergency department for sudden chest pain, left-sided and non-radiating lasted for several minutes, awoke him from sleep with no associated symptoms. He is known to have Diabetes type-2 and hypertension on oral therapy. Cardiac markers were within the normal limit. The patient was discharged home with an appointment at the cardiology outpatient clinic. Echocardiography was done and revealed mildly reduced left ventricular (LV) systolic function, Ejection Fraction of 46%, asymmetric LV hypertrophy affecting the apical segments with aneurysm, and calcified apical thrombus. CT coronary angiography was done with non-significant Left Anterior Descending artery lesions and left ventricular hypertrophy affecting the apex with calcified apical thrombus. Further investigation by cardiac MRI revealed apical thrombus and late apical uptake suggesting Endomyocardial Fibrosis of possible eosinophilic etiology. The patient continued to have attacks of similar chest pain, for which stress cardiac MRI was done and was negative for ischemia. Another diagnostic workup was done, including hematological and serological tests such as Antinuclear Antibodies and Schistosoma Antibodies. The patient was kept on valsartan and Bisoprolol with oral anticoagulant (vitamin K antagonist) and Rosuvastatin. EMF may have a heterogeneous presentation and should be considered in a patient with calcific apical thrombus without previous history of cardiac problem, even in the non-tropical region.

Association of corneal nerve fiber measures with cognitive function in dementia.

OBJECTIVES: Corneal confocal microscopy (CCM) is a noninvasive ophthalmic technique that identifies corneal nerve degeneration in a range of peripheral neuropathies and in patients with multiple sclerosis, Parkinson's disease, and amyotrophic lateral sclerosis. We sought to determine whether there is any association of corneal nerve fiber measures with cognitive function and functional independence in patients with MCI and dementia. METHODS: In this study, 76 nondiabetic participants with MCI (n = 30), dementia (n = 26), and healthy age-matched controls (n = 20) underwent assessment of cognitive and physical function and CCM. RESULTS: There was a progressive reduction in corneal nerve fiber density (CNFD), branch density (CNBD), and fiber length (CNFL) (P < 0.0001) in patients with MCI and dementia compared to healthy controls. Adjusted for confounders, all three corneal nerve fiber measures were significantly associated with cognitive function (P < 0.05) and functional independence (P < 0.01) in MCI and dementia. The area under the ROC curve to distinguish MCI with CNFD, CNBD, and CNFL was 69.1%, 73.2%, and 73.0% and for dementia it was 84.8%, 84.2%, and 86.2%, respectively. INTERPRETATION: CCM demonstrates corneal nerve fiber loss, which is associated with a decline in cognitive function and functional independence in patients with MCI and dementia.

A Rare Right Ventricular Involvement of Eosinophilic Granulomatosis Demonstrated by Cardiac MRI.

BACKGROUND: Eosinophilic granulomatosis with polyangiitis (EGPA) is a rare systemic vasculitis with a prevalence rate of seven per million. Cardiac involvement was reported in 20-50%, yet with improved diagnostic methods, the frequency of cardiac involvement is expected to be even higher. It can result in significant morbidity and mortality, accounting for about 50% of death. Cardiac magnetic resonance (CMR) imaging is used to evaluate the myocardium, valves, coronary arteries, pericardium, also to assess cardiac structure and function. Perfusion study allows tissue characterisation with a suggestive pattern of late gadolinium enhancement. CASE REPORT: We report a rare case of EGPA in a 54-year-old male patient who presented with fever, sore throat and dizziness. Echocardiography showed a filling defect at the apex of the right ventricle (RV). CMR findings suggested the diagnosis of EGPA by demonstrating an impressive lesion at RV apex with the typical 3-layer appearance and thrombus formation. Post-gadolinium subendocardial hyperenhancement suggested focal involvement at the inferolateral wall of the left ventricle. Computed Tomography (CT) was done to rule out calcific or soft plaques of the coronary arteries, small vessel vasculitis and small aneurysm. CT scan showed a low-attenuation lesion at the inner wall of the right ventricle. In the lungs, bilateral interstitial changes and bilateral cystic bronchiectases were found. Under appropriate treatment, the patient improved clinically. CONCLUSIONS: It is of crucial importance to perform full cardiac imaging that includes CMR even in asymptomatic patients with suspected EGPA, since early identification of cardiac involvement may allow to apply appropriate therapy and full recovery of the patient.
