BACKGROUND Low-pressure cardiac tamponade is a form of cardiac tamponade in which a comparatively low pericardial pressure results in cardiac compression because of low filling pressure. This syndrome is poorly characterized because only isolated cases have been reported. We conducted a study of its clinical and hemodynamic profiles. METHODS AND RESULTS From 1986 through 2004, we evaluated al...

in this study, trans-pulmonic valvular gradient of 51 patients with congenital pulmonary stenosis measured by cw-doppler and cardiac catheterization were compared to find whether they are comparable and if doppler method is accurate enough for interventional decision-making. results showed that findings in both methods were comparable and doppler method is accurate and enough for clinical decis...

Assessment of the severity of aortic stenosis remains a commonly encountered clinical problem. Noninvasive evaluation has to date not proven sufficiently accurate in most cases to permit clinical decision making in the individual patient. Therefore, cardiac catheterization and measurement of the valve area with use of the Gorlin equation remains the standard approach in patients with suspected ...

There are approximately 2 million cardiac catheterizations that occur every year in the United States and with an aging population this number continues to rise. Adverse events due to this procedure occur at low rates and include stroke, arrhythmia, and myocardial infarctions. Due to the high volume of procedures there are a growing number of adverse events. Stroke after cardiac catheterization...
