Comparison of Right Ventricular Longitudinal Strain Imaging, Tricuspid Annular Plane Systolic Excursion, and Cardiac Biomarkers for Early Diagnosis of Cardiac Involvement and Risk Stratification in AL Amyloidosis: a Five Year Cohort Study

Objectives: The aim was to determine the role of assessing right ventricular (RV) function, using standard echocardiography and Doppler myocardial imaging (DMI), in the early diagnosis of cardiac amyloidosis (CA) and in prediction of mortality. Methods: A total of 249 patients with AL amyloidosis were categorized on the basis of left ventricular thickness and E' velocity, and compared to 38 age- and sex-matched controls. Standard echocardiographic parameters of RV function were assessed, and longitudinal systolic myocardial velocity, strain rate (sSR), and strain (sS) were determined for the basal and middle RV free wall segments. Patients were followed for the endpoint of mortality. Result…
