Organ Injury Scaling
Cardiac

Grade Injury Description AIS-90
I Blunt cardiac injury with minor ECG abnormality (nonspecific ST or T wave changes, premature atrial or ventricular contraction or persistent sinus tachycardia) 3
Blunt or penetrating pericardial wound without cardiac injury, cardiac tamponade or cardiac herniation 3
 
II Blunt cardiac injury with heart block or ischaemic changes without cardiac failure 3
Penetrating tangential cardiac wound up to but not extending through endocardium, without tamponade 3-4
 
III Blunt cardiac injury with sustained or multifocal ventricular contractions 3-4
Blunt or penetrating cardiac injury with septal rupture, pulmonary or tricuspid incompetence, papillary muscle dysfunction or distal coronary artery occlusion without cardiac failure 3-4
Blunt pericardial laceration with cardiac herniation 3-4
Blunt cardiac injury with cardiac failure 3-4
Penetrating tangential myocardial wound up to but not through endocardium, with tamponade 3
 
IV Blunt or penetrating cardiac injury with septal rupture, pulmonary or tricuspid incompetence, papillary muscle dysfunction or distal coronary artery occlusion producing cardiac failure 3
Blunt or penetrating cardiac injury with aortic or mitral incompetence 3
Blunt or penetrating cardiac injury of the right ventricle, right or left atrium 5
 
V Blunt or penetating cardiac injury with proximal coronary artery occlusion 5
Blunt or penetrating left ventricular perforation 5
Stellate injuries <50% tissue loss of the right ventricle, right or left atrium 5
 
VI Blunt avulsion of the heart 6
Penetrating would producing >50% tissue loss of a chamber 6
 
Advance one grade multiple penetrating wounds to a single chamber or multiple chamber involvement.
