Evaluation of the appropriate root pressure for maintaining heartbeat during an aortic cross-clamp for primary repair of the aortic arch in premature infants with associated cardiac anomalies

We developed a new cardiopulmonary bypass (CPB) method to minimize myocardial damage during aortic arch reconstruction. In this method, coronary flow and heartbeat were stabilized by maintaining the aortic root pressure with an adjusted preload of the ventricle during aortic cross-clamping. This stu...
