“…The atrial collapse has also been documented in severe pectus excavatum or large pericardial effusion in the absence of tamponade due to extrinsic compression. 4,5 This case highlights the importance of atrial collapse duration and respiratory variation rather than depth of collapse in deciphering tamponade physiology in a case of large pericardial effusion.…”

The echocardiographic markers that occur in sequence in cardiac tamponade are inferior vena cava plethora, right atrial diastolic collapse, exaggerated inspiratory variation in mitral and tricuspid velocities and finally right ventricular diastolic collapse. Contrary to popular belief, the degree of atrial inversion does not correlate with the presence or absence of tamponade physiology, however, the right atrial inversion time (exceeding one-third of the cardiac cycle) significantly improves the sensitivity of atrial collapse in predicting tamponade. We present here an important demonstration of fundamental physiology of respirophasic variation of right atrial collapse in cardiac tamponade.
