Annals of Cardiac Anaesthesia | Volume 21 | Issue 4 | October‐December 2018 462 necessitates the use of CPB that might compound the situation. Moreover, the intraoperative preservation of an antegrade pulmonary flow necessitates the maintenance of higher SVC pressures to promote downstream flow through the BDCPA. The need of higher SVC pressures in this subset of patients increases the risk of pleural effusion and chylothorax in the postoperative period causing respiratory compromise. At the same time, on‐table extubation may lead to atelectasis and hypoxia‐related increases in PVR.[3] These factors complicate the decision with regard to the ideal time of extubating these patients.
