OBJECTIVES The study evaluated the prognostic value of interventricular and intraventricular dyssynchrony in idiopathic dilated cardiomyopathy (IDC). BACKGROUND Biventricular pacing is an emerging treatment for patients with dilated cardiomyopathy and ventricular dyssynchrony. The prognostic values of interventricular and intraventricular dyssynchrony(More)
AIMS The outcome of alcoholic cardiomyopathy is thought to be better than idiopathic dilated cardiomyopathy if patients abstain from alcohol. The aim of this study was to compare the long-term clinical outcome of alcoholic and idiopathic dilated cardiomyopathy. METHODS AND RESULTS Of 134 patients with dilated cardiomyopathy and normal coronary(More)
BACKGROUND To overcome some of the limitations imposed by planar imaging, we aimed to optimize the use of first harmonic Fourier phase analysis (FPA) in electrocardiography-gated blood-pool single photon emission computed tomography (GBPS) by comparing different quantitative, 3-dimensional methods. METHODS AND RESULTS Three groups of patients who(More)
To evaluate the diagnostic performance of Fourier phase analysis of gated blood pool single-photon emission computed tomography (GBP SPECT) in arrhythmogenic right ventricular (RV) cardiomyopathy, 18 patients with confirmed arrhythmogenic RV cardiomyopathy underwent GBP SPECT and x-ray cineangiography. Results were compared with data obtained with GBP SPECT(More)
Nonreentrant atrioventricular (AV) nodal tachycardia is a rare form of arrhythmia due to simultaneous anterograde conduction in dual AV pathways, one atrial impulse triggering two ventricular complexes. We report the case of a 74-year-old man referred for incessant palpitations resistant to antiarrhythmic medication, and effort dyspnea. A nonreentrant AV(More)
Studies were performed in unanesthetized normotensive and spontaneously hypertensive rats (SHR) to compare the effects of naloxone. In normotensive Wistar rats, naloxone did not change blood pressure (BP) and nociceptive threshold, but it induced a dose-related diuretic response. Whereas in SHR naloxone decreased nociceptive threshold and lowered BP when(More)
There is considerable variability in segmental wall motion abnormalities and in the prognosis of idiopathic dilated cardiomyopathy (IDC). Radionuclide ventriculography with Fourier analysis was performed in 107 patients with angiographically proved IDC. Amplitude analysis located the wall motion abnormalities. Using phase analysis in the left and right(More)
Using Fourier phase analysis of equilibrium radionuclide angiography in both ventricles, inter- and intraventricular delays were correlated with QRS morphology and duration in 103 patients with idiopathic dilated cardiomyopathy. We found that left bundle branch block on the left axis may reflect a high intra-left ventricular dyssynchrony. A precise(More)
Biventricular pacing is a new form of treatment for patients with dilated cardiomyopathy and ventricular dyssynchrony. Limited information is available regarding the relationship between ventricular dyssynchrony and risk markers of ventricular arrhythmias in idiopathic dilated cardiomyopathy (IDC). In 103 patients with IDC, Fourier phase analysis of both(More)
Amyloidosis is a severe systemic disease. Cardiac involvement may occur in the three main types of amyloidosis (acquired monoclonal light-chain, hereditary transthyretin and senile amyloidosis) and has a major impact on prognosis. Imaging the heart to characterize and detect early cardiac involvement is one of the major aims in the assessment of this(More)
