Abstract
Severe cyanotic cardiac diseases such as extreme type of Fallot or truncus arteriosus present to cardiac surgeons a serious problem, for which up to the present day no satisfactory surgical treatment has been available. A new operative procedure "aorta banding" has been devised by occluding the lower thoracic aorta by placing a Teflon tape around it. Careful experimental studies indicated that this procedure resulted in increased pulmonary flow and was found to be relatively a safe procedure. Application of the aorta banding in clinical cases resulted in dramatic disappearance of anoxic spells and decrease of cyanosis.
