Case ReportsContrast guided two-dimensional echocardiography for needle localization during pericardiocentesis: a case report.
The authors present a case of pericardial effusion that was percutaneously drained using agitated saline for echocardiographic contrast guidance. This technique can safely confirm the location of a pericardiocentesis needle in the pericardial space prior to tract dilation and insertion of the pericardial drainage catheter. In this instance, this technique prevented the inadvertent placement of the pericardiocentesis catheter in the right ventricle.

Echocardiographic effects of changing atrioventricular delay in cardiac resynchronization therapy based on displacement.
In studies showing benefits of cardiac resynchronization therapy (CRT), individual atrioventricular (AV) delays have been optimized using echocardiography. However, the method for AV delay optimization remains controversial. ⋯ Individual optimal AV delay programming provides significant improvement in left ventricular performance and hemodynamics. Displacement analysis and the VTI(LVOT) are interchangeable, whereas diastolic filling time cannot be recommended.
