Abstract We report a case of a 83-year-old female, who had an admission for dyspnea. Laboratory showed D-dimer 1000 ng/ml, haemoglobin 12.4 mg/dL, CPR 0.08mg/dl whereas on Arterial Blood Gas test she had hypoxia with respiratory alkalosis. In view of suspected pulmonary embolism, she underwent Thoracic Computed Tomography scan that excluded it. During the stay the patient seemed more symptomatic while in standing position(with SpO2s 89% while supine plunging to 50% while standing): ABGs were performed both standing (reservoir 15 l/min pH 7.50, pO2 37.2 mmHg, pCO2 37.1 mmHg, HCO3 28.9 mmol/l) and recumbent position (reservoir 15 l/min pH 7.47, pO2 65.5 mmHg, pCO2 35.1 mmHg, HCO3 25.6 mmol), showing a difference of 28 mmHg. Subsequently the patient underwent v/p pulmonary scintigraphy: no signs of pulmonary embolism though it revealed a multiple focus of capitation Tc-99m macro aggregated albumin in brain, thyroid and kidneys (IMG top), compatible for veno-arterial shunt. Trans-esophageal echocardiography (TOE) revealed a massive stretched patent foramen ovale (PFO) with continuous right-to-left shunting through the atria. The bubble test (IMG bottom) confirmed the presence of patency along with sudden passage of microbubbles through the foramen. Qp/Qs = 0.8, due to volume overload in the left atrium from the right atrium. The imaging along with clinical scenario confirmed the suspected diagnosis of platypnea-orthodeoxia, finding the patent foramen ovale as the anatomical cause. Platypnea-orthodeoxia syndrome is a clinical condition characterized by dyspnea. Typically blood oxygen saturation declines with standing position while it resolves with recumbent. The classification entails 3 groups: intracardiac shunting (most common presentation), pulmonary shunting, ventilation-perfusion mismatch. Presence of multiple focus of albumin macroaggregates outside the lungs in v/p scintigraphy examination is suggestive for veno-arteriuous shunt: without shunt, normally all the albumin aggregates are hampered in the lungs’ field. Images in bottom are taken in sequence from a single acquisition during the TOE, in one single cardiac beat. Here is depicted the evidence of the PFO, the influx of bubbles in the right atrium and the instantaneous and massive shunt of the bubbles across the interatrial septum, in the left atrium. Usually the diagnosis is performed within 55 years old: it is interesting how late the diagnosis occurred in this patient with such resounding clinical manifestation. Top Scintigraphy with ventilation and perfusion lung scan sequences. Next, scintigraphy with capitation of Tc-99m macro aggregated albumin in brain, thyroid and kidneys. Bottom, Transesophageal echocardiogram: images taken within the same heart beat proving right-to-left passage of bubble across the septum. Abstract P1317 Figure.

Abstract Introduction Right heart thrombi are rare, found in up to 20% of pulmonary emboli (PE), and associated with significantly increased mortality(1). A thrombus entrapped in a PFO is a rare form of right heart thromboembolism. Clinical Case A 73-year-old male patient who had dyspnea for 10 days, was transferred to our hospital for the surgical treatment of a cardiac tumor. We performed TTE which revealed a free floating, huge mass( measuring more than 8 cm long) in the right atrium, that protruded in the right ventricle, with high risk of embolization. Another smaller mass, attached to the interatrial septum. Severe right ventricular dysfunction and severe pulmonary hypertension were present. Contrast-enhanced computer tomography was performed, which revealed severe bilateral pulmonary artery emboli with complete occlusion of right pulmonary artery branch. Clinical and paraclinical data strongly suggested that the huge cardiac mass was a thrombus that originated from the lower extremity veins. TEE showed that the thrombus was entrapped through the PFO, with a smaller part in the left atrium and the biggest portion in the right atrium. The patient underwent an emergent on-pump surgical cardiac and right pulmonary artery embolectomy. The right atrium was opened and a huge intracardiac thrombus with a lengh of 14 cm extending from the coronary sinus, to PFO in the left atrium and also in the right ventricle was removed. The right branch of the pulmonary artery was opened and a large volume of clot- 9 cm long- was removed. The patient was removed from cardio-pulmonary by-pass (CPB) on high doses of norepinephrine and dobutamine and necessitated initiation of venous-arterial ECMO to support the severe right heart dysfunction. He was extubated after 10 days, with little improvement in the clinical status. Transthoracic echocardiography showed smaller right heart cavities), normal left ventricular function, but persistent severe RV dysfunction and severe pulmonary hypertension. In the thirteenth postoperative day, he installed cardio-respiratory arrest and he died. Discussion In this report we describe a case of a patient with a huge intracardiac thrombus, entrapped through a PFO, associated with massive pulmonary embolism, with late presentation in our hospital and severe refractory right heart dysfunction. He underwent successful embolectomy, which is a unique procedure in the treatment of an acute pulmonary embolism and entrapped thrombus in a PFO. Conclusion The treatment of choice for emboli-in-transit is controversial. In a recent review, surgical thromboembolectomy showed a trend toward improved survival and significantly reduced systemic emboli compared to anticoagulation. Thrombolysis in these patients may cause fragmentation of thrombus and systemic embolization, resulting in increased mortality. Management decisions should be made with multidisciplinary coordination and consideration of complicating factors such as PFO. Abstract P689 Figure. Extensive biatrial thrombus

The Chiari network is an embryological remnant found in the right atrium, mostly without any significant pathophysiological consequences. However, several cardiac associations are reported in the literature including supraventricular tachyarrhythmias. We present a case of a 96-year-old body donor with a stroke episode and intermittent atrial fibrillations. The dissection of the heart revealed the presence of an immense Chiari network with a large central thrombus. The role of a Chiari network in the pathogenesis of stroke and pulmonary embolism is discussed.
