@entity296 may result from severe @entity130 . Therefore, left (LV) and right ventricular (RV) function were prospectively assessed by ECG-gated blood pool radionuclide (RN) angiography in 25 consecutive @entity1 who had sustained severe @entity130 including blunt @entity764 . Focal abnormalities of RV and LV wall motion were defined in 17 @entity1 ; 12, RV; two, LV; and three, biventricular. In two @entity1 traumatic @entity997 was also demonstrated, and subsequently verified by contrast angiography. Other means to detect @entity296 (enzymatic, electrocardiographic, and @entity52547 scintigraphy) proved to be insensitive when compared to RN angiography. Two of the five deaths in the group were attributed to refractory @entity943 . Surgical or post-mortem evidence of traumatic @entity296 was obtained in five instances when RN angiography indicated contusion. Of the 13 @entity1 available for followup examinations, 11 showed complete or partial resolution of the abnormality and two were unchanged. Comprehensive cardiopulmonary monitoring revealed an inverse relationship between right ventricular ejection fraction (RVEF) and pulmonary vascular resistance (PVR) (R2 = 0.42; p < 0.01) and between the PVR and left ventricular ejection fraction (LVEF) (R2 = 0.48; p < 0.01) and left ventricular end-diastolic volume (LVEDV) (R2 = 0.69; p < 0.01). Further, as right ventricular end-diastolic volume (RVEDV) was increased in @entity130 , left ventricular function and compliance were reduced. In blunt @entity764 RV contusion occurs more frequently than previously recognized and positive RN angiography constitutes prima facie evidence of direct @entity296 . Further, LV function remains preload dependent, but may be @entity308 by elevated PVR impeding the blood flow from RV to LV and/or decreases in LV compliance.
