{Abstract}: <B>UNASSIGNED: </B>Two-dimensional speckle tracking echocardiography (2D-STE) and three-dimensional echocardiography (3DE) may overcome many limitations of the conventional 2D echocardiography (2DE) in assessing right ventricular (RV) function. We sought to determine whether characteristics of the right atrium and right ventricle as measured by 2D-STE and 3DE are associated with cardiac mortality in patients with ischemic heart failure, over a 6-year follow-up.<BR><B>UNASSIGNED: </B>The inclusion criteria were ischemic cardiomyopathy with left ventricular ejection fraction of <40% diagnosed using standard 2DE, 2D-STE, and 3DE examination. Patients were followed for 6 years, and cardiac mortality was recorded.<BR><B>UNASSIGNED: </B>The study sample comprised a total of 54 participants. During the period of follow-up, 24% (13/54) died. The 2DE models showed that being older, having a higher body mass index (BMI), having higher systolic pulmonary artery pressure (SPAP), and a lower RV global longitudinal strain were associated with cardiac mortality in our cohort after 6-year follow-up. Finally, the 3DE models showed that in addition to being older, having higher BMI, having a higher SPAP baseline, lower baseline 3DE RV stroke volume, and larger 3DE RV end-diastolic volume and 3DE RV end-systolic volume were associated with cardiac mortality over 6-year follow-up.<BR><B>UNASSIGNED: </B>This study provides evidence that RV dysfunction as seen on 2D-STE and 3DE could be associated with increased risk of cardiac-related mortality in patients with heart failure over 6 years.
