The diagnostic value of transthoracic echocardiography for eosinophilic myocarditis: A single center experience from China

摘要

The aim of this study is to explore the value of transthoracic echocardiography in the diagnosis of eosinophilic myocarditis. The echocardiographic characteristics of nine patients with eosinophilic myocarditis in our hospital between January 2004 and January 2012 were retrospectively reviewed. In our study, four of the nine patients were diagnosed to have small pericardial effusion. The obliteration of the apical cavity was observed in five of the nine patients. There were six patients with both mitral and tricuspid regurgitation, one patient with only mitral regurgitation, and one patient with only tricuspid regurgitation. Transthoracic echocardiography showed that the diameters of the left and right atria were both increased in eight of the nine patients. The diameter of the left ventricle was increased in five patients, and the right ventricular diameter was increased in four patients. The left ventricular ejection fraction was decreased in two of the nine patients. Five of the nine patients had pulmonary hypertension, and one patient had severe pulmonary hypertension. Transthoracic echocardiography is the primary method for the diagnosis of eosinophilic myocarditis and is also useful in follow-up of the disease. (C) 2015 Elsevier Ireland Ltd. All rights reserved.
