The exclusion criteria are as follows: (i) defects associated with other cardiac lesions requiring a surgical approach; body-weight <10kg and age 8 Wood units; (ii) Aortic regurgitation; (iii) Aortic valve prolapse; and right-to-left shunt. Before intervention, an informed written consent was obtained from patients' Guardian/parents.
The combining hypothesis for the association of PFO with numerous clinical conditions such as cryptogenic stroke, migraine, sleep apnea, pulmonary edema due to high altitude, platypnea-orthodeoxia, decompression sickness (DCS), is based on the passage of a particulate, gas bubble, or chemical substance in venous circulation to systemic circulation without being exposed to the lungs through a right-to-left shunt. The left atrium pressure is higher than the right atrium, which prevents passage by holding down the septum primum flap to septum secundum.
ES (right-to-left shunt across an interatrial/interventricular defect or aortic-pulmonary shunt) has a predicted risk of mortality in pregnancy from 16% (newer data) to 36% (older data).
Another instance of development of a right-to-left shunt is Reverse Lutembacher syndrome, in which an additional cardiac anomaly i.e.
This patient notably had a very elevated hematocrit and continued hypoxia despite 100% FiO2 administration, which is suggestive of a right-to-left shunt and a fixed obstruction to pulmonary blood flow as seen in Tetralogy of Fallot.
Subsequently, a transesophageal echocardiogram (TEE) was performed that revealed a patent foramen ovale with right-to-left shunt. This raised the concern for paradoxical embolism as the cause of patient's TIA.
Patent foramen ovale was defined on the basis of transesophageal echocardiographic evidence of a separation between the septum primum and septum secundum, with the demonstration of right-to-left shunt by contrast injection [16].
In the case of an increase in the right atrial pressure exceeding left atrial pressure (as observed at the end of Valsalva maneuvers, such as coughing, sneezing, squatting, defecation, or micturition), a transient right-to-left shunt may occur carrying particulate matter, such as thrombi, into the systemic circulation.
Scuba diving is associated with decompression sickness and air emboli, which can be a mechanism of cerebral ischemia, especially in patients with a right-to-left shunt, such as with PFO.
A bedside echocardiography and chest computed tomography revealed no evidence of right-to-left shunt.
Use of transthoracic echocardiography with harmonic imaging and agitated saline contrast allows for the accurate diagnosis of suspected right-to-left shunt through a PFO/ASD in patients diagnosed with cardioembolic stroke [9].
