Multi-View 3-D Fusion Echocardiography: Enhancing Clinical Feasibility with a Novel Processing Technique.

A novel system for fusing 3-D echocardiography data sets from complementary acoustic windows was evaluated in 12 healthy volunteers and 12 patients with heart failure. We hypothesized that 3-D fusion would enable 3-D echocardiography in patients with limited acoustic windows. At least nine 3-D data sets were recorded, while three infrared cameras tracked the position and orientation of the transducer and chest respiratory movements.

Variability of left ventricular volume and ejection fraction measurements using contrast echocardiography: The influence of the left ventricular length measurements in a large cohort of patients during monitoring cardiotoxic effects of chemotherapy.

Objective: To investigate the influence of length difference in left ventricular (LV) long axis between the apical four-chamber and two-chamber views on measurements of LV volumes and ejection fraction (EF).

Methods: Seven hundred consecutive cancer patients underwent contrast echocardiography from July 2010 to May 2014. All patients received the echocardiographic contrast agent Definity.
