After birth — when left atrial pressure exceeds right atrial pressure — the septum secundum is pressed against the septum primum and the foramen ovale i

Our own group at the University of California, San Francisco, has also participated in these developments by combining exercise testing with echocardiographic hemodynamics. The reasons for this

Changing Practices, Changing Educationments, by cardiac catheterization, are invasive and costly and therefore not suitable for routine and serial assessment. Although M-mode and two-dimensional echocardiography might be useful to detect the narrowing of aortic valve, they lack the specificity for evaluating the severity of aortic steno

Today Doppler techniques are used for routine diagnostic procedures. Extensive experimental and clinical advantages and limitatio
