Multivessel coronary artery aneurysms as a complication of chronic active Epstein-Barr virus infection: An atypical and occasional complication
Coronary artery aneurysm (CAA) is defined as a coronary artery dilatation >1.5 times the diameter of the normal adjacent segments or the diameter of the patient's largest coronary vessel. It is an uncommon disease, present in 1–4% of coronary angiography findings.1IgG4-related disease: Coronary arteritis masquerading as coronary “masses”
A 64-year-old man with a history of psoriasis and latent tuberculosis presented to the emergency department with cough and dyspnea. Transthoracic echocardiogram (TTE) showed a large pericardial effusion with early echocardiographic signs of tamponade and a well circumscribed right atrioventricular groove mass extending into the pericardial space, moving with the cardiac cycle without independent mobility (Fig. 1). Pericardiocentesis drained 1 L of sanguinous fluid with a lymphocytic predominance and negative infectious and cytologic work-up.Prognostic impact of identifying etiology of prosthetic valve dysfunction with CT
In 132 patients with suspected PVD, an etiology was diagnosed on CT in 60.6% and on echocardiography in 34.1% patients. On adjusted multivariable analyses, CT diagnosis of structural valve degeneration was significantly associated with the composite outcome of reoperation or death whereas echocardiography diagnosis was not. CT assessment of PVD had prognostic significance for hard outcomes and should be considered in the diagnostic evaluation of patients with suspected PVD.Cardiac computed tomography in the contemporary evaluation of infective endocarditis
Increasing data have accumulated on the role of Cardiac Computed Tomography (CCT) in infective endocarditis (IE) with high accuracy for large vegetations, perivalvular complications and for exclusion of coronary artery disease to avoid invasive angiography. CCT can further help to clarify the etiology of infective prosthetic valve dysfunction (e.g. malposition, abscess, leak, vegetation or mass). Structural interventions have increased the relevance of CCT in valvular heart disease and have amplified its use.Multimodality imaging of an adult with Shone complex
Shone complex is a rare combination of valvular or supravalvular aortic stenosis, supra-valvular mitral membrane, parachute mitral valve, and coarctation of the aorta. This article presents an unusual case of a 40-year-old woman who presented with a history of progressive dyspnea. We describe the main imaging features and protocol used for visualizing this syndrome using various imaging modalities.Primary diagnosis of quadricuspid aortic valve with multislice computed tomography
A 46-year-old man with hypertension was evaluated for atypical chest pain. An echocardiogram showed mild aortic and mitral regurgitation. A treadmill stress test showed asymptomatic 1-mm downsloping ST-segment depression at 6.5 minutes, with rapid resolution of the ST depression in recovery. He was referred for 64-slice cardiac computed tomography (CT) to exclude coronary artery disease. Cardiac CT, performed with tube current modulation, showed an abnormal origin of the left main coronary artery with leftward and posterior displacement.
