BNP vs Tissue Doppler for LV Filling Pressure
Mitral Doppler E/Ea correlates better with PCWP than BNP and is more specific for predicting PCWP > 15 mm Hg. -
Optimal Frequency of BNP Testing
At this time, BNP seems to be a useful initial test that should not be repeated during short hospital stays. -
More Help Estimating Filling Pressures by Echo/Doppler
Reflex tachycardia, during a Valsalva maneuver, is a sign of normal LV filling. -
Echo Diagnosis of Prosthetic Valve Endocarditis
Mild, perivalvular regurgitation cannot be used as a diagnostic criteria for prosthetic valve endocarditis. -
Gender Differences in Ventricular Arrhythmia Recurrence
These data should force us to look at factors other than the traditional variables we have used to assess risks among patients with a history of ventricular arrhythmias. -

The basic conclusion is that we should give the patient just what he or she needs and the devices we implant should be designed to fit the patient. -
Prevention of Cardiovascular Events After Percutaneous Coronary Intervention
