Correlation between late gadolinium enhancement and diastolic function in hypertrophic cardiomyopathy assessed by magnetic resonance imaging.

Background: Diastolic dysfunction is common in patients with overt hypertrophic cardiomyopathy (HCM). Steady-state cine magnetic resonance imaging (MRI) enables measurement of the diastolic function of the left ventricle (LV), and late gadolinium enhanced MRI can delineate the presence and extent of fibrosis in HCM. The purpose of this study was to determine the relationship between the extent of myocardial fibrosis demonstrated by late gadolinium-enhanced MRI and diastolic dysfunction.

Two cases of dilated cardiomyopathy with right ventricular wall degeneration demonstrated by late gadolinium enhanced MRI.

Right heart failure is prominent in some patients with dilated cardiomyopathy (DCM). In this article, we present right ventricular wall degeneration and fibrosis demonstrated by late gadolinium enhanced magnetic resonance imaging (MRI) in patients with DCM.

A case of isolated tricuspid valve infective endocarditis caused by Abiotrophia defectiva.

A 17-year-old man with a history of dental caries was admitted to our hospital because of 1-week high fever. There was no history of previous cardiac disease. He denied drug abuse.

A case of acute myocardial infarction caused by left main trunk disease with dilated cardiomyopathy.

A case of acute myocardial infarction caused by left main trunk disease with dilated cardiomyopathy is presented. Cardiac MRI findings may suggest the etiology of left ventricular dysfunction in this case is idiopathic dilated cardiomyopathy, which associated with acute myocardial infarction caused by left main trunk disease.

Thallium-201 SPECT and low-dose dobutamine stress cine MRI for predicting functional recovery of regional myocardial contraction in patients with myocardial infarction.

Objectives: The purpose of this study was to compare the diagnostic performances of Tl-201 single photon emission computed tomography (SPECT) and dobutamine stress cine magnetic resonance imaging (MRI) for predicting functional recovery of regional myocardial contraction in patients after myocardial infarction.

Methods: Twenty patients underwent Tl-201 SPECT and MRI 3-4 weeks after onset of myocardial infarction. Cine MR images were acquired in the resting state and during dobutamine stress.
