“…1 Right ventricular diastolic collapse is sensitive and specific in the diagnosis of tamponade. [3][4][5][6][7] This finding is observed when intrapericardial (in our case intrathoracic) pressure equals, and transiently exceeds, right ventricular diastolic pressure. The two-dimensional echocardiography noted in our patient suggested cardiac tamponade.…”

“…Recent two-di mensional échocardiographie studies have shown that such abnormalities, right atrial collapse and right ven tricular diastolic collapse, are reliable indicators of wellestablished cardiac tamponade [1][2][3][5][6][7], Accordingly, when overt hemodynamic decompensation marked by hypotension, jugular venous distension, signs of markedly decreased cardiac output or abnormal pulsus paradoxus develop in a patient with pericardial effusion, the presence of these échocardiographie signs can con firm that cardiac tamponade is likely to be the cause of the hemodynamic deterioration. However, in échocar diographie studies of patients with pericardial effusion, both right atrial collapse and right ventricular diastolic collapse have been observed in some in the absence of conventional signs of tamponade [1,7].…”

Right atrial collapse (RAC) and right ventricular diastolic collapse (RVDC) have been shown to be useful two-dimensional échocardiographie signs in well-established cardiac tamponade. To assess the value of these signs in cardiac tamponade of varying severity, we studied 8 closed-chest spontaneously breathing dogs with twodimensional echocardiography during varying grades of tamponade induced by intrapericardial saline infusion via a preplaced catheter. Early tamponade was defined as the state when pericardial effusion caused a 20% decline in cardiac output but with normal systolic arterial pressure and a pulsus paradoxus less than 10 mm Hg. Moderate and severe tamponade were stages with progressively decreasing cardiac output and systolic arterial pressure and increasing pulsus paradoxus over 10 mm Hg. Neither RAC nor RVDC was present in any animal in the control state. Sensitivity of RAC was 50% during early tamponade and 100% during moderate and severe tamponade; the specificity was 100% during all grades of tamponade. The sensitivity of RVDC was 38, 63 and 75% during early, moderate and severe tamponade; the specificity was 88% during all stages. Thus, presence of RAC and RVDC in pericardial effusion indicates that hemodynamic deterioration has begun even though conventional signs such as pulsus paradoxus may be absent. As tamponade progresses, the sensitivity of both signs increases. At all grades of tamponade, RAC tends to be more sensitive than RVDC.

“…These clinical findings defined the condition known as classical clinical tamponade. With the availability of echocardiography it was soon realised11 12 that some patients with pericardial effusion but without clinical tamponade show findings suggesting raised intrapericardial pressure—namely, collapse of the right sided cardiac chambers. Cardiologists were puzzled about the clinical relevance of these findings, especially regarding the indication of pericardial drainage, since these findings were interpreted as “impending” cardiac tamponade.…”
