Prognostic significance of strain Doppler imaging in light-chain amyloidosis.
OBJECTIVES To clarify the prognostic value of strain and strain rate imaging in light-chain (AL) amyloidosis. BACKGROUND Myocardial strain and strain rate Doppler imaging are objective measurements that may detect regional subtle myocardial functional abnormalities in patients with amyloidosis. METHODS We prospectively examined 119 consecutive, untreated patients with biopsy-proven AL amylo...
متن کاملEchocardiographic assessment of the cardiac amyloidoses.
Cardiac amyloidosis is a cardiomyopathy characterized by increased left ventricular (LV) wall thickness and normal or decreased LV cavity size. Congestive heart failure in cardiac amyloidosis is generally considered a predominantly diastolic phenomenon, with systolic dysfunction only occurring in late-stage disease. Echocardiography is a noninvasive, reproducible method of assessing cardiac fea...
متن کاملErratum 'Prognostic implication of relative regional strain ratio in cardiac amyloidosis'.
OBJECTIVE Cardiac amyloidosis (CA) is a rapidly progressive disease that portends poor prognosis. Our objective was to evaluate the prognostic impact of relative regional strain ratio (RRSR, a measure of the relative apical sparing of longitudinal strain (LS)) in CA. METHODS This is a retrospective study evaluating 97 patients with CA from 2004 to 2013. Patients were included if they met crit...
متن کاملPrognostic utility of late gadolinium enhancement on cardiac magnetic resonance in cardiac amyloidosis: a meta-analysis
Background Cardiac Amyloidosis (CA) is an important prognostic indicator in patients with systemic amyloidosis. Cardiac MRI has emerged as imaging modality of choice to evaluate patients with CA. Delayed hyper-enhancement cardiac magnetic resonance (DHE-CMR) provides incremental diagnostic and prognostic utility in suspected CA. We performed a meta-analysis to evaluate the prognostic role of LG...
متن کاملThe right ventricular end-systolic volume index predicts mortality in patients with cardiac amyloidosis
Background Cardiac amyloidosis (CA) is generally characterized by a poor prognosis and significantly increased mortality. Although right ventricular (RV) dysfunction is strong predictor of outcome in AL amyloidosis, there are limited data regarding the prognostic significance of RV size. We sought to investigate whether cardiovascular magnetic resonance (CMR) assessment of RV size has prognosti...
