OBJECTIVES This investigation was designed 1) to assess whether the early diastolic velocity of the mitral annulus (Ea) obtained with Doppler tissue imaging (DTI) behaves as a preload-independent index of left ventricular (LV) relaxation; and 2) to evaluate the relation of the mitral E/Ea ratio to LV filling pressures. BACKGROUND Recent observations(More)
Echocardiographic imaging is ideally suited for the evaluation of cardiac mechanics because of its intrinsically dynamic nature. Because for decades, echocardiography has been the only imaging modality that allows dynamic imaging of the heart, it is only natural that new, increasingly automated techniques for sophisticated analysis of cardiac mechanics have(More)
Background—The role of the giant protein titin in patients with heart failure is not well established. We investigated titin expression in patients with end-stage heart failure resulting from nonischemic dilated cardiomyopathy, in particular as it relates to left ventricular (LV) myocardial stiffness and LV function. Methods and Results—SDS-agarose gels(More)

Advances since the 1998 publication of the Recommendations for Performance and Interpretation of Stress Echocardiography 1 include improvements in imaging equipment, refinements in stress testing protocols and standards for image interpretation , and important progress toward quantitative analysis. Moreover, the roles of stress echocardiog-raphy for cardiac(More)
BACKGROUND Early transmitral velocity/tissue Doppler mitral annular early diastolic velocity (E/Ea) and B-type natriuretic peptide (BNP) have been correlated with left ventricular filling pressures, yet there are no data on how these 2 estimates of left ventricular filling pressures compare. METHODS AND RESULTS Patients admitted to intensive care(More)
AIMS To examine myocardial deformation and rotation in patients with heart failure, and elucidate the underlying mechanisms that account for normal ejection fraction (EF) in patients with diastolic heart failure (DHF). METHODS AND RESULTS Fifty consecutive patients presenting with congestive heart failure (age: 58 +/- 16 years) underwent simultaneous(More)
OBJECTIVES The aim of this study was to validate a novel, angle-independent, feature-tracking method for the echocardiographic quantitation of regional function. BACKGROUND A new echocardiographic method, Velocity Vector Imaging (VVI) (syngo Velocity Vector Imaging technology, Siemens Medical Solutions, Ultrasound Division, Mountain View, California), has(More)
BACKGROUND Left ventricular outflow tract (LVOT) obstruction is frequently responsible for symptoms in hypertrophic obstructive cardiomyopathy (HOCM). Medical therapy is often not sufficient to control these symptoms, and surgical myotomy-myomectomy is required. METHODS AND RESULTS We enrolled 33 symptomatic patients with HOCM and obstruction (>/=40 mm Hg(More)
