Abstract

BACKGROUND: Left ventricular (LV) ejection fraction (EF) measured by two-dimensional echocardiographic (2DE) imaging is an important correlate of survival. Real-time three-dimensional echocardiographic (3DE) imaging has addressed some of the limitations of 2DE imaging. The aim of this study was to determine whether 3DE imaging is more predictive of outcomes than 2DE imaging. METHODS: A total of 529 patients undergoing LV assessment with 2DE and 3DE imaging in 2003 and 2004 at a tertiary referral cardiac center were studied. Patients had a high frequency of cardiovascular risk factors. Images were gathered over four cardiac cycles using a matrix-array transducer, with measurements performed o..
