Predicting outcome of rethoracotomy for suspected pericardial tamponade following cardio-thoracic surgery in the intensive care unit

Table 3 Echocardiographic findings prior to rethoracotomy for suspected pericardial tamponade.

	CV SOFA unchanged n = 9	CV SOFA decreased n = 8	P
Pericardial effusion (cm)	2.0 (1.0-4.0)	2.0 (0-4.0)	0.91
Clot	6 (67)	5 (63)	1.0
Right atrial collapse	4 (44)	1 (13)	0.29
Left atrial collapse	0	2 (25)	0.21
Right ventricular collapse	1 (11)	0	1.0
Flow variations	4 (44)	0	0.08
Low end-systolic left ventricular volume	4 (67)	4 (50)	0.63

Median (range) or number (percentage), where appropriate. CV SOFA = cardiovascular sequential organ failure assessment score.
