Atrial Septal Defect and the Risk of Ischemic Stroke in the Perioperative Period of Noncardiac Surgery
Stroke is a serious complication of non-cardiac surgery. Congenital defects of the interatrial septum may be a potent risk factor for perioperative stroke. The aim of the present study was to determine the association between atrial septal defect (ASD) or patent foramen ovale (PFO) and in-hospital perioperative ischemic stroke after non-cardiac surgery in a large nationwide cohort of patients hospitalized in the United States. Patients undergoing noncardiac surgery between 2004 and 2014 were identified using the Healthcare Cost and Utilization Project's National Inpatient Sample.

Economy Class Syndrome, patent foramen ovale and stroke
Whether or not air travel in a patient with patent foramen ovale (PFO) is a risk factor for cerebral embolism is unresolved. This is illustrated by a recent case report of the Massachusetts General Hospital in the New England Journal of Medicine of deep venous thrombosis and stroke associated with air travel. The discussant concluded that because of the relatively short flight “it seems unlikely that air travel was a major risk factor” 1. This may well be true for deep venous thrombosis per se, the risk of which has been shown to increase with duration of the flight 2.
