Ring-shaped calcific constrictive pericarditis strangling the heart: a case report
Constrictive pericarditis is caused by fibrosis and calcification of the pericardium, processes that inhibit diastolic filling of the heart. For the diagnosis of constrictive pericarditis, a combined approach is used to evaluate the morphologic pericardial abnormalities in conjunction with assessment of the functional and hemodynamic changes. We report novel findings of chest computed tomograph...
متن کاملA ring on the heart.
A 79-year old man was admitted for heart failure. Calcification of the pericardium was discovered on X-ray (Fig. 1). Cardiac computed tomography revealed a unique atrioventricular calcification ring along the atrioventricular groove (Fig. 2). Angiography also demonstrated a special calcification ring (Supplementary Video 1). Constrictive pericarditis was diagnosed. Pericardiectomy was successfu...
متن کاملTransmittance of MIM Waveguides Containing Semi-Circular Ring Shaped and Rectangular Ring Shaped Grooves
In this paper the transmittance of metal-insulator-metal (MIM) waveguides containing semi-circular ring shaped and rectangular ring shaped grooves are investigated. By varying groove parameters their effects on the transmittance of the MIM waveguides are investigated. The results show that the transmittance spectra of the waveguides have maximum and minimum points, and by using appropriate para...
متن کاملRare presentation of asymptomatic pericardial effusion: hemangioma of the atrioventricular groove in cardiac magnetic resonance imaging.
C ardiac hemangiomas are rare vascular tumors that account for 2% to 5% of benign cardiac masses. They are constituted by endothelial cells lining vascular channels, and they can be histologically classified into capillary, cavernous, or arteriovenous hemangiomas. They may affect the endocar-1 The natural history of pericardial hemangiomas is difficult to predict, and its course may be complica...
متن کاملAtypical Chest X-Ray Calcification in an Idiopathic Constrictive Pericarditis Case
Constrictive pericarditis is an uncommon cause of heart failure. It is a clinical entity caused by thickening, fibrosis, and/or calcification of the pericardium. We present a 50-year-old female patient who was admitted to our institution with a 6-month history of progressive dyspnea on exertion, abdominal swelling, and lower extremity edema. Her chest X-ray revealed an oblique linear calcificat...
