Abstract
Clot-in-transit (CIT) is defined as a mobile echogenic material in the right atrium or ventricle as observed on ultrasound. A right heart free-floating thrombus is unusual when there is no structural disease of the heart or atrial fibrillation. Cardiopulmonary collapse and quick death can come from CIT, which occurs when a blood clot moves from the heart to the lungs. There are some clinical case reports of a large volume thrombus that was freely floating in the right heart in an asymptomatic patient, and the best therapeutic options are uncertain. Although several trials have been conducted on the treatment of CIT, clinical judgment is still used to determine the best treatment for right heart thrombus (RHT), especially when associated with pulmonary embolism (PE). In this review article, we discuss various diagnostic modalities and treatment options for this rare malady. We studied in detail their clinical impact on patients according to past research studies.

Abstract
Impending paradoxical embolism is a rare but potentially life-threatening complication of venous thromboembolism that is usually associated with acute pulmonary embolism and a right to left atrial shunt. Patients may have associated right ventricular pressure or volume overload with subsequent failure. Transesophageal echocardiography is the preferred diagnostic test of choice in this patient group. Definitive management has yet to be clearly defined. However, emergent surgical removal of the entrapped intracardiac blood thrombus may be necessary. In this article, we review a case of impending paradoxical embolism managed surgically and describe the perioperative anesthetic considerations in this patient population, along with the role of intraoperative transesophageal echocardiography.

Abstract
A 51-year-old male with history of resected renal cell carcinoma and prior pulmonary embolism presented with tachypnea, tachycardia and progressive dyspnea on exertion. Chest computed tomography revealed bilateral acute pulmonary embolism. Transthoracic echocardiogram showed severe pulmonary hypertension with severe cor-pulmonale and presence of a large worm-like thrombus extending across the foramen ovale, entering both ventricles through the mitral and tricuspid valves. The risks of anti-coagulation, pharmacologic thrombolysis, and surgical thrombectomy, in a hemodynamically stable patient, posed a significant therapeutic dilemma. Ultimately, a collective decision was made to start anticoagulation, without incident. At 1 month follow up, complete resolution of the intracardiac thrombus, pulmonary hypertension, and cor-pulmonale were observed with full clinical recovery of the patient.

Abstract
Percutaneous patent foramen ovale (PFO) closure is a treatment for cryptogenic stroke and migraine headache. The goal of this study was to assess long-term outcomes of patients treated with percutaneous PFO closure. Records of patients with percutaneous PFO closure at Emory University Hospital from February 2002 to July 2009 were reviewed. Follow-up telephone questionnaire and chart review assessed recurrent stroke, migraine, and complications. Data was reviewed on 414 consecutive patients. Long-term follow-up was obtained in 207 of patients, and mean follow up was 4.6 ± 2.0 years. Cryptogenic stroke was the primary indication for intervention in 193 (93%) patients. Thirteen (7%) patients had a recurrent neurologic event post closure. In patients with multiple neurological events at baseline, 17% (n = 11) had a recurrent event, compared with 2% (n = 2) of patients with a single neurological event prior to PFO-closure (P < 0.002). Post closure, migraine frequency and severity declined from 4.5 to 1.1 migraine/month (P < 0.01) and 7.2 to 3.6 out of 10 (P < 0.01) in patients with history of migraine (n = 60). Thirty-day mortality was 1% (n = 2). One patient had device erosion 5 years post-procedure requiring emergent surgery. Atrial fibrillation was newly diagnosed in 8 (4%) patients within 6 months. In conclusion, the long-term rate of recurrent stroke after PFO closure is low in patients with a single neurological event at baseline. Serious long-term complications after PFO closure are rare. PFO closure may decrease the frequency and severity of migraine.

Abstract
A 72 year-old woman was admitted with a one-week history of weakness, right limb pain and progressive breathlessness. Her blood pressure was 60/40 mmHg, ECG showed inverted T waves in the precordial leads and incomplete right bundle branch block (RBBB). Transthoracic echocardiography revealed a large serpentine mobile mass across the atrial septum and mitrale valve extending into the left ventricular cavity. The right ventricle was dilated and peak systolic tricuspid annular velocity (RV-Sm) was 6.5 cm/sn, indicate right ventricular systolic function was severely depressed. Transoesophageal echocardiography showed a large, mobile thrombus in the foramen ovale, extending into the left atrium and ventricle. As the patient was in a haemodynamically compromised condition, high dose rapid infusion of streptokinase was administered. However, the thrombus did not fully resolve with this intervention. Therefore, low dose continuous streptokinase infusion was administered for an additional 72 h resulting in full resolution of the lesion by the third day of therapy. The optimal management of impending paradoxical embolism remains unclear. Prolonged continuous thrombolytic infusion may be a option for patients who do not experience full resolution of high risk thrombi with conventional thrombolytic therapy.

Abstract
Patent foramen ovale has become the subject of increasing interest in modern cardiovascular disease. This has been the result of several factors including, among others, description of paradoxical embolism, documentation of patent foramen ovale with right to left shunt, the rather ubiquitous use of echocardiography, the issue of stroke prevention, and more recently, the relationship between patent foramen ovale and migraine.

Abstract
A 61-year-old gentleman presented to our institute with increasing dyspnoea. He had a previous diagnosis of a deep vein thrombus and was maintained on coumarin therapy. Investigations to evaluate the cause of his dyspnoea included a chest computed tomography (CT) scan and a bronchoscopy. The CT scan suggested the presence of granulomatous lung disease although subsequent sampling for acid-fast bacilli and sarcoidosis were negative. The patient's health declined and an urgent transthoracic echocardiogram was performed. This demonstrated the presence of a large thrombus lodged within a patent foramen ovale. The patient died shortly later. At postmortem, a large thrombus was confirmed to be straddling across a patent foramen ovale. Lung histology demonstrated that the micronodular opacities visualized on the chest CT scan were in fact pulmonary emboli with fibrosis. We present the echocardiographic appearance of the patent foramen ovale thrombus and its rare pathological correlate at postmortem.

Abstract
Impending paradoxical embolism (IPDE) is the presence of an entrapped thrombus through the patent foramen ovale (PFO). Usually IPDE are diagnosed by echocardiography or thoracic CT-scan performed during the evaluation of patient presenting with a suspicion of pulmonary embolism (PE). We report the case of a 73-year-old patient presenting with a very large IPDE successfully treated with cardiac surgery and we focus our discussion on the treatment modalities of this rare entity (anticoagulation alone, fibrinolytic regimens, cardiac surgery, percutaneous thrombectomy) and on PFO management after IPDE.

Abstract
We report a case of massive right pulmonary embolism with a patent foramen ovale and straddling thrombus, occurring a few days after cesarean section in a 31-year-old woman. Preoperatively, a mass was seen echocardiographically in four cardiac cavities. We performed emergency surgery because of the patient's acute hemodynamic deterioration. Intraoperatively, we found a thrombus entrapped in the patent foramen ovale. Most of the thrombus was floating in the right atrium and a long end was found in the left atrium, in addition to the pulmonary emboli. We removed the thrombus, closed the patent foramen ovale by direct suturing, and performed pulmonary embolectomy. Histological examination confirmed thrombi. Doppler examination of the venous system did not reveal any possible source of the thrombus. The patient is now well and free from recurrence of embolic disease 1 year after surgery. We review the literature on this relatively unusual thromboembolic disease.

Abstract
The recognition, evaluation and treatment of patent foramen ovale has attracted increasing interest as the importance and frequency of paradoxical embolism has become better understood. The interest in this field has been driven largely by the widespread application of echocardiography with identification of a patent foramen ovale and/or an atrial septal aneurysm. The evaluation of the role of a patent foramen ovale in patients with a neurologic event is complex because the patent foramen ovale or atrial septal aneurysm may either be an innocent bystander or could be the etiologic mechanisms involved in the paradoxical embolus. In patients younger than 55 years, a causal relationship between a patent foramen ovale/atrial septal aneurysm and a neurologic ischemic event is considerably stronger than in those patients older than 55 years. In patients with a presumed diagnosis of paradoxical embolus in the setting of a patent foramen ovale, percutaneous closure is now possible and 2 devices are relatively widely used. Both of these devices reliably close the defect with a very acceptable risk profile and have been found in the longer term to be associated with excellent outcome. The exact role, however, that these devices play vis a vis continued medical therapy for prevention of recurrent events is being tested in 2 randomized clinical trials. The field continues to change with new technology being developed and with new applications. A recently exciting finding has been the identification that closure of a patent foramen ovale may be associated with dramatic improvement in symptoms of patients with disabling migraine headaches. Other potential applications of these devices include those patients who are deep-sea divers, in whom the potential for "bends" exists, or high altitude airplane pilots.
