BACKGROUND Chronic aortic valve disease (AVD) is characterized by progressive accumulation of interstitial myocardial fibrosis (MF). However, assessment of MF accumulation has only been possible through histologic analyses of endomyocardial biopsies. We sought to evaluate contrast-enhanced magnetic resonance imaging (ce-MRI) as a noninvasive method to(More)
We report a case of anterolateral papillary muscle rupture in a 22-year-old man who had blunt chest trauma caused by a car accident. Transesophageal echocardiography revealed severe mitral regurgitation caused by the rupture. He successfully underwent emergency mitral valve replacement and was discharged 9 days after the surgical correction.
The patient was a 70-year-old female with antecedents of diabetes mellitus and hypertension, being followed up in the outpatient care clinic due to chronic anemia after corrective surgery for angiodysplasia of the proximal jejunum, in whom an image suggestive of left atrial myxoma was found on routine transthoracic echocardiography. Then multiplanar(More)
Contrast echocardiography has been demonstrated useful for left ventricular opacification and improvement of endocardial border delineation. Another important clinical application of this technique refers to the better characterization of cardiac tumors and masses. We here described an asymptomatic patient with cystic mass attached to submitral valve(More)
A 33-year-old female patient, with a 4-year history of hypertension plus a 3-year history of systemic lupus erythematosus, who had been taking high dosages of corticosteroids, has shown repetitive respiratory infections and congestive heart failure for the past 8 months. Angiocardiography confirmed the diagnosis of aortic insufficiency with aneurysmatic(More)
