Predisposing Factor

• Platypnea: dyspnea in upright position • Orthodeoxia: hypoxemia in upright position • Both conditions occur with normal right heart pressures • Right pneumonectomy is most common predisposing factor • Pulmonary embolus is next most common predisposing factor • Theory: after right pneumonectomy, gradual rotation of heart toward the horizontal position and torsion when patient is in the upright position open a patent foramen ovale (PFO). Blood flow from the inferior vena cava goes directly to and through the PFO...

Abstract Background The presence of a patent foramen ovale (PFO) is associated with several medical conditions, including cryptogenic left circulation thromboembolism. PFO closure was demonstrated to reduce recurrent ischaemic stroke in patients with prior cryptogenic stroke. The presence of an inferior vena cava filter (IVCF), however, may impede a transfemoral PFO closure procedure. Case summary We describe the case of a 50-year-old man with a PFO suffering from ischaemic stroke from paradoxical thromboembolism originating from deep vein thrombosis and requiring an IVCF. After deep vein thrombosis resolution, due to the high risk of stroke recurrences, the patient was recommended PFO closure. IVCF retrieval by the interventional radiologist was first attempted but failed. A transfemoral PFO closure procedure was thus endeavoured with the IVCF in place and was successful. The patient was then discharged in good clinical status and no stroke recurrences were reported at 5 months follow-up. Discussion Albeit an IVCF provides benefit in patients with recurrent thromboembolic events despite adequate anticoagulation therapy, its presence may hinder interventional procedures necessitating delivery systems to advance through the inferior vena cava. We reported on a successful PFO closure procedure via a femoral venous access in a patient with an IVCF in place, thus demonstrating the feasibility of advancing delivery systems through an IVCF. As interventional procedures requiring the advancement of delivery systems through the inferior vena cava are becoming increasingly common, the feasibility of IVCF crossing with catheters and delivery systems alike paves the way for novel interventional possibilities.

Platypnea orthodeoxia syndrome (POS) occurs when an upright position results in acute-onset hypoxemia and is relieved with recumbency. POS can be due to intracardiac shunting, intrapulmonary shunting, ventilation-perfusion mismatch, or a combination of these. We report a case of POS that developed 3 days post liver transplantation as a result of new-onset right to left shunting across a patent foramen ovale. Right heart catheterization revealed a posteriorly directed inferior vena cava likely due to altered inferior vena cava—right atrial junction anatomy as a result of liver transplantation. The patient underwent successful transcatheter patent foramen ovale closure with a 25-mm Gore Cardioform septal occluder device with immediate and sustained improvement in hypoxia.

Abstract This brief communication reports what appears to be the first case of an interaction between an inferior vena cava filter and a patent foramen ovale closure device. During removal of the inferior vena cava filter, the patent foramen ovale closure device was unintentionally removed. This case report serves to highlight the possible interaction of these two devices.

Inferior vena cava (IVC) diameter and respirophasic variation are commonly used echocardiographic indices to estimate right atrial pressure. While dilatation of the IVC and reduced collapsibility have traditionally been associated with elevated right heart filling pressures, the significance of isolated IVC dilatation in the absence of raised filling pressures remains poorly understood. We present a case of an asymptomatic 28-year-old male incidentally found to have IVC dilatation, reduced inspiratory collapse, and normal right heart pressures.
