COMPLICATIONS OF CARDIAC INVESTIGATION

Abstract
A review is presented of the significant complications of special cardiac investigations experienced by a pediatric cardiac investigatory unit during a period of 8 years. Six deaths resulting from such procedures are reported. Two deaths resulted from arrhythmia and 4 were associated with injection of radio-opaque dye. The importance of cerebral complications of various types is discussed. Cerebral complications arising in the presence of right-to-left shunt and with manipulations in the systemic circuit are described. The hazards of investigation of sick infants with serious congenital heart disease are also stressed.
