Patent foramen ovale and ascending aortic aneurysm with platypnea-orthodeoxia syndrome

Interatrial defect, ventricular septal defect and patent ductus arteriosus in a 2-day-old newborn infant

“…Interatrial defects [1][2][3], ventricular septal defects [4][5][6][7], and patent ductus arteriosus [8] can occur as part of more congenital cardiac malformations or as an isolate finding. We present a case of interatrial defect associated with ventricular septal defect and patent ductus arteriosus in a 3-day-old newborn infant.…”

Persistent Right Venous Valve: Insights From Multimodality Imaging

“…Chiari network has little physiological significance but may cause technical difficulty during percutaneous procedures. 19,20 Difficulty in inferior caval vein cannulation due to a large Eustachian valve has been documented during cardiac surgery for the establishment of cardiopulmonary bypass. 21,22 Prominent Eustachian and Thebesian valves have also been documented to interfere with access to the coronary sinus during pacemaker implantation.…”

“…Other anatomic features that have been described to exaggerate the right to left shunt include loculated pericardial effusion, aortic aneurysm, aortic elongation, and postpneumonectomy. 19,20 Figure 11 illustrates a situation where, the presence of a small right atrium due to altered anatomy post-thoracic surgery, a PRVV, an aneurysmal interatrial septum with spinnaker-like motion, a patent foramen ovale, and persistent fetal flow pattern resulted in significant right to left shunt and positional hypoxemia.…”

A case of platypnea-orthodeoxia syndrome caused by the interaction between the presence of corrected transposition of the great arteries and patent foramen ovale

“…It has been proposed that upright posture may induce changes in the relationship of intracardiac structures, such as between the inferior vena cava and interatrial septum, resulting in augmentation of right-to-left shunting through an interatrial communication [6]. Decreased right heart compliance following pneumonectomy or localized extrinsic compression may also result in exaggerated right-to-left shunting during upright posture [7]. We herein present a novel case of platypnea-orthodeoxia caused by the interaction between the presence of Corrected Transposition of the Great Arteries (CTGA) and PFO.…”
