Left ventricular and atrial function in systemic light chains amyloidosis: an echocardiography and cardiac magnetic resonance comparison
نویسندگان
چکیده
Background Cardiac involvement in systemic light-chain amyloidosis (AL) is characterized by slightly decreased systolic left ventricular function (LV) function and typically a diastolic dysfunction including left atrial (LA) enlargement. Cardiac magnetic resonance (CMR) is often performed in AL to accurately assess chambers size and function. We aimed to compare features of LV systolic and diastolic function obtained by 2D transthoracic echocardiography (TTE), with morphological and functional myocardial LV (presence of late gadolinium enhancement: LGE) and LA (volume and emptying fraction) parameters as assessed by CMR in a consecutive series of patients with cardiac AL.

OBJECTIVE The purpose of this study was to find whether Cardiac Magnetic Resonance (CMR) could assess the myocardial interstitium in patients suffering from systemic amyloidosis with normal left ventricular ejection fraction. METHODS Twenty Six patients in whom systemic amyloidosis was confirmed by kidney biopsy were investigated. Five patients with normal left ventricular ejection fraction w...

A 71-year old-man presented with 4 posturally related syncopal episodes. He carried a diagnosis of asymptomatic hypertrophic cardiomyopathy (HCM) without obstruction based on an echocardiogram 7 years earlier. Echocardiography at the time of syncope evaluation demonstrated a hyperdynamic left ventricle with a septal thickness of 20 mm (an increase of 4 mm from an earlier echocardiogram), newly ...

Introduction: Many patients have only diastolic dysfunction without any abnormality in systolic function. We compared cardiac diastolic parameters obtained by gated myocardial perfusion SPECT (Gated SPECT) with those evaluated by echocardiography. Methods: Forty-nine patients (aged 37-85 years, 19 males and 30 women) underwent Gated SPECT and echocardiogr...

Cardiac amyloidosis is a prognostically critical condition, since it is a frequent cause of death in patients with systemic amyloidosis. Lee et al. reported, for the first time, describing systemic amyloidosis in Korea from the perspective of cardiologists. In this paper, the authors enrolled 129 systemic amyloidosis patients retrospectively from 1999 to 2011. They showed that cardiac involve w...
