Abstract
Double-chambered right ventricle (DCRV) causing right ventricular outflow tract (RVOT) obstruction, is an uncommon cardiac disease especially when first diagnosed in adults. Diagnosis can be challenging when it is asymptomatic. We report a 40-year-old man who was referred to cardiology for work-up of a heart murmur that was found on a routine physical examination prior to obtaining a pilot's license. A transesophageal echocardiogram (TEE) revealed a DCRV and a small perimembranous ventricular septal defect (VSD) with left-to-right shunt and severe RVOT obstruction. Right heart catheterization showed an estimated gradient of 135 mm Hg across the two chambers due to subpulmonary stenosis. The pressure in the proximal right ventricular chamber was 160/25 mm Hg and 25/17 mm Hg in the distal chamber. Surgical correction was successfully performed. A postoperative TEE showed no residual gradients across the RVOT. DCRV has been reported as a rare disease in adults. It is difficult to diagnose DCRV using the transthoracic echocardiogram in adults. However, subcostal windows can offer better visualization of subpulmonary outflow tract compared to the parasternal and apical windows. TEE remains the main non-invasive modality for diagnosing DCRV in adults. Cardiac magnetic resonance imaging and invasive testing can provide further information to confirm the diagnosis and guide therapeutic decisions.

Abstract
BACKGROUND Platypnea-orthodeoxia syndrome (POS) is a rare clinical phenomenon, associating normal oxygen saturation in a supine position and arterial hypoxemia in an upright position. This pathology can be secondary to an intracardiac shunt, a pulmonary vascular shunt or a ventilation-perfusion mismatch. Cardiac POS occurs in the presence of a right-to-left cardiac shunt, most commonly through a patent foramen ovale (PFO). METHODS AND RESULTS From our single-center prospective database of percutaneous PFO closure we identified five patients (4 females, mean age: 77 ± 11 years) out of 224 (2.2%) patients with a PFO who presented with a POS of cardiac origin. Transthoracic and transoesophageal echocardiographic examinations revealed the underlying mechanisms of POS and the diagnosis was confirmed by right-and-left cardiac catheterization (RLC) and by measuring serial blood oxygen saturation in the pulmonary veins and left atrium in supine and upright positions. PFO was associated with atrial septal aneurysm and a persistent prominent Eustachian valve in 3 patients. All patients underwent a successful percutaneous PFO closure without any immediate or subsequent complications (mean follow-up of 24 ± 18 months). Immediately after the procedure, mean arterial oxygen saturation improved from 83% ± 3 to 93% ± 2 in an upright position and symptoms disappeared. CONCLUSION POS is a rare and under-diagnosed pathology that must be actively investigated in the presence of position-dependent hypoxemia. The diagnostic work-up must exclude other causes of hypoxemia and confirm the intracardiac shunt using either contrast echocardiography or RLC. For cardiac POS, percutaneous PFO closure is a safe and effective technique that immediately relieves orthodeoxia and patient symptoms.

Abstract
Quadricuspid aortic valve is a rare congenital heart disease that is mostly detected incidentally during echocardiography or angiography, or at autopsy. This pathology is frequently associated with other congenital anomalies of the heart such as abnormalities of coronary ostia, coronary stenosis, aortic root dilation and coarctation of the aorta, as well as significant aortic valve dysfunction. Herein is presented the first documented case of an asymptomatic middle-aged male patient with incidentally diagnosed quadricuspid aortic valve and a preserved valve function associated with a patent foramen ovale and reverse right-left leak identified during the Valsalva maneuver. No other associated cardiac abnormalities were identified.

Abstract
BACKGROUND Pivotal clinical trials suggest that intravenous (IV) recombinant tissue plasminogen activator (rt-PA) benefits stroke patients regardless of the underlying etiology. Paradoxical strokes, presumed to be caused by fibrin-rich clots originating in the venous circulation, may respond better to fibrinolysis than other ischemic stroke subtypes. In this study, we compared the response with IV rt-PA in paradoxical stroke patients and other stroke subtypes. METHODS In total, 486 patients treated with IV rt-PA at a single institution were retrospectively reviewed. Adjudication of stroke mechanism was based on chart review. Five major stroke mechanisms--cardioembolic, artery-to-artery emboli, lacunar, cryptogenic, and paradoxical--were identified by final diagnosis from chart reviews. Mimics, undefined etiology, and defined etiology not falling into the major mechanisms were excluded. Analysis of variance and general linear model were used to assess the differences between groups. RESULTS A total of 323 patients were analyzed. We found significant differences in clinical outcome between stroke mechanisms, including discharge National Institutes of Health Stroke Scale (NIHSS) (P=.007), discharge Rankin (P=.011), discharge disposition (P=.000), and infarct volume (P=.007). Post hoc analysis showed that cardioembolic patients had the worst outcomes (discharge NIHSS score 11.12±12.26), whereas paradoxical strokes had the best outcomes (discharge NIHSS score 3.67±4.90), but these did not approach statistical significance. However, regression analysis showed that 4 variables--congestive heart failure, admission NIHSS, age, and mean infarct volume--rather than stroke mechanism were the true predictors of poor outcome. CONCLUSIONS Paradoxical strokes had better outcomes after IV fibrinolysis than other ischemic stroke subtypes, but this difference is attributable to younger age and milder stroke severity on presentation.

Abstract
The aim of this study was to test the hypothesis that ear oximetry immediately after the release of a sustained Valsalva maneuver accurately detects patent foramen ovale (PFO). One hundred sixty-five scuba divers underwent transesophageal echocardiography (TEE; reference method) for PFO assessment. Ear oximetry of the right earlobe was performed in a different room within a time frame of 2 hours before or after TEE. The subject and the oximetry operator were unaware of the results of TEE. Oxygen saturation (SO(2)) measurements were obtained at baseline and during the release phase of 4 Valsalva maneuvers within 10 minutes, and the average SO(2) change (SO(2) at baseline minus SO(2) at Valsalva release) was determined as the primary study end point. One hundred seventeen divers had no PFO, and 48 (29%) had PFO by TEE (mean age 39 ± 8 years). The average SO(2) change was 0.79 ± 1.13% (i.e., a slight absolute SO(2) decrease in response to the Valsalva maneuver) in the group without PFO and 1.67 ± 1.19% in the PFO group (p <0.0001). Using receiver-operating characteristic curve analysis, a PFO as defined by TEE could be detected at a threshold of a Valsalva-induced decrease in SO(2) of ≥0.825 percentage points in comparison to baseline (sensitivity 0.756, specificity 0.706, area under the receiver-operating characteristic curve 0.763, p <0.0001, negative predictive value 0.882). In conclusion, the entirely noninvasive method of ear oximetry in response to repetitive Valsalva maneuvers is accurate and useful as a screening method for the detection of a PFO, as shown in this study of divers.

Abstract
Transcatheter patent foramen ovale (PFO) closure is an alternative to antiplatelet or anticoagulative therapy in patients with cryptogenic stroke, and it is associated with a small incidence of periprocedural sequelae. Because embolization of PFO closure devices is a very rare procedural complication, data on its frequency, causes, and management are sparse. We sought to review the medical literature and the cases of PFO closure-device embolization at our institution with the aim of identifying likely problems and reporting potential solutions. Out of 310 adult patients who underwent transcatheter PFO closure from June 2002 through April 2011, there were 2 cases (0.6%) of PFO closure-device embolization. In both patients, hypermobile septum primum and thick septum secundum were present. In one patient, failure to use a sizing balloon might have resulted in an underestimation of the PFO's size. In both patients, device embolization was identified in a timely fashion, the embolized device was safely retrieved, and the PFO was percutaneously closed with success. The incidence of PFO closure-device embolization is very low. The cases described here underscore the importance of imaging in the identification of morphologic predispositions to closure-device malpositioning, in the recognition of impending embolization, and in the timely management of embolization.

Abstract
We encountered a patient with the overlapping disorders of migraine with aura, migraine-triggered seizures and recurrent transient hemiparesis caused by atypical hemiplegic migraines with motor weakness during headache attacks, but not during the aura period, or paradoxical cerebral embolism. The patient displayed a giant Eustachian valve and patent foramen ovale, through which a spontaneous right-to-left shunt was revealed on transesophageal echocardiography. We considered that the overlapping disorders in the present case were closely related to the spontaneous right-to-left shunt caused by the giant Eustachian valve.

Abstract
Comorbidity may be defined as the association of two or more diseases in individuals at a frequency greater than that expected statistically by chance. Studying the co-occurrence of two disorders requires a careful statistical analysis before any clear conclusion on causality is reached. Many studies have looked for an association between migraine and many diseases, reporting several sometimes controversial comorbidities in migraine subjects. Although migraine is more common in women than in men, very few studies have analyzed the comorbidity of perimenstrual migraine, a migraine sub-type characterized by attacks of migraine without aura related to menstruation. We review the studies on migraine comorbidities, particularly migraine without aura in women.

Abstract
A 16-year-old girl arrived intubated to the emergency department. She had shortness of breath and cough for 2 days with leg pain. On arrival, she was hemodynamically stable with an unremarkable physical exam. Electrocardiogram revealed a prolonged QT interval; laboratory work-up was normal except for an elevated dimerized plasmin fragment D. Acute pulmonary embolism was confirmed by a chest computed tomography scan. A lower extremity duplex scan was negative and echocardiogram revealed a patent foramen ovale with bidirectional shunting. An inferior vena cava filter was placed to prevent acute recurrence and unfractionated heparin was initiated. The next day she was noted to have right hemiparesis. Stroke was confirmed by magnetic resonance imaging. The patient underwent mechanical clot retrieval and was discharged on anticoagulation therapy to a brain rehabilitation unit.

Abstract
This report describes an obese 39-year-old man who experienced ST-segment elevation myocardial infarction with total thrombotic occlusion of the right coronary artery. Culprit vessel flow was improved by aspiration. Data suggested that myocardial infarction had resulted from paradoxical embolus via a patent foramen ovale triggered by the Mueller maneuver, which had induced negative intrathoracic pressure following an acute increase of right-heart volume in the context of obesity and sleep-disordered breathing (SDB). Obesity is increasing among younger populations and it represents a risk for SDB and thrombosis. Thus, this mechanism should be included within the differential diagnosis for myocardial infarction in young patients.

Abstract
A 27-year-old Royal Marine presented to his sickbay following two episodes of sudden onset visual disturbance. A subsequent MRI Scan demonstrated ischaemic changes in the territory of his right posterior cerebral artery. Transthoracic echocardiography was normal but a bubble contrast study was strongly positive indicating the presence of a relatively large patent foramen ovale (PFO). He underwent endovascular closure of his patent foramen ovale and was subsequently upgraded back to full duties. A 35-year-old Army Sergeant presented with sudden onset collapse, right sided weakness, dysarthria and confusion. He was airlifted to a Host Nation hospital and following a normal CT head underwent thrombolysis in the Emergency Department. This was unsuccessful but a CT guided embolectomy led to complete resolution of symptoms. Subsequent transthoracic echo revealed a PFO. He underwent endovascular closure and has since been returned to full duties. The incidence of PFO is common affecting 27% of the population but the incidence of ischaemic stroke in young adults (aged 15-45 years old) is rare. This maybe linked to the size of the PFOs in symptomatic individuals. These case reports emphasise the requirement for further investigation of individuals presenting with collapse and persisting neurology. Differential diagnosis and initial management for primary care and pre-hospital clinicians is also reviewed.

Abstract
We encountered a patient with brain abscess presumably caused by dental infection. The patient displayed patent foramen ovale (PFO) and a giant Eustachian valve, through which spontaneous right-to-left shunt was revealed by transesophageal echocardiography. Reviewing the literature, we find additional cases where brain abscess originated from an increased amount of flora commonly found in the oral cavity that bypassed the pulmonary vascular bed and the lymphatic system through PFO. Additionally, a Eustachian valve should be considered an adjunctive risk factor for initiating a spontaneous right-to-left shunt and predisposing cryptogenic brain abscess in patients with PFO.

Abstract
BACKGROUND Incidence of patent foramen ovale (PFO) has been estimated at 25% in the general population and 6% for larger defects. Data on the relationship between PFO morphology and the risk of stroke are limited. PFO closure has become a common practice in many centres, although recent guidelines limit indications for such treatment to patients with cryptogenic (recurrent) stroke. AIM To investigate whether PFO morphology assessed by transoesophageal echocardiography (TOE) differed between patients with symptoms and those who had an asymptomatic PFO. METHODS We analysed 88 consecutive patients (48 female, 40 male; mean age 36.1 ± 16.2 [range 18-59] years) who underwent TOE before transcatheter PFO closure due to a cryptogenic cerebrovascular event (Group I) and compared them to 88 consecutive patients (49 female, 39 male; mean age 35.7 ± 14.2 [range 18-57] years) with an asymptomatic PFO found incidentally on TOE (Group II). The diagnosis of stroke was based on the occurrence of a new acute focal neurological deficit, with neurological signs and symptoms persisting for >24 h, subsequently confirmed by computed tomography and/or magnetic resonance imaging. Multiplane TOE was conducted as per guidelines using commercially available instruments. The interatrial septum was viewed in the transverse midoesophageal 4-chamber view and the longitudinal biatrial-bicaval view. PFO was diagnosed with intravenous injections of agitated saline while the patient was at rest and during the Valsalva manoeuvre. We analysed PFO size (resting and maximal separation of the septum primum and secundum during the Valsalva manoeuvre), tunnel length (maximal overlap of the septum primum and secundum), presence of an atrial septal aneurysm (excursion 〉 15 mm), shunt severity (mild: 3-5, moderate: 6-25, severe 〉 25 microbubbles) and prominence of the Eustachian valve. RESULTS The two groups did not differ with respect to age and sex distribution. Group I showed larger PFO size (maximal separation 3.9 ± 1.4 vs. 1.3 ± 1.3 mm, p 〈 0.0001), longer tunnel length (14 ± 6 vs. 12 ± 5.5 mm, p 〈 0.05) and a greater frequency of atrial septal aneurysm (55% vs. 15%, p 〈 0.0001) compared to Group II (controls). Group I was also characterised by a higher proportion of large PFOs (≤ 4 mm; 50% vs. 18%, p 〈 0.001) and severe shunt (40% vs. 2%, p 〈 0.0001). CONCLUSIONS PFO in symptomatic patients is larger in size, has a longer tunnel and is more frequently associated with atrial septal aneurysm. Asymptomatic patients with PFO characteristics similar to that seen in stroke patients require more careful clinical evaluation. It may be debated whether such patients should be recruited to prospective trials to evaluate indications for PFO closure in stroke prevention.

Abstract
INTRODUCTION The aim of this study was to evaluate the systolic function of the left atrial appendage (LAA) in a group with and without patent foramen ovale (PFO) who suffered ischemic cerebrovascular events. MATERIAL AND METHODS Between September 2010 and October 2011, 17 patients were referred for transesophageal echocardiography (TEE) after suffering a stroke. PFO was defined as the passage of at least one bubble through atrial septum with bubble test. We compared systolic velocity in the appendage between patients with and without PFO and a control group. RESULTS Were 8 women and 9 men, mean age 54.1 ± 19.5 years and 8 patients were under 55 years of age. All patients had suffered a ischemic cerebrovascular events, 41.2% had stroke, 52.9% transient ischemic attack and amaurosis fugax 5.9%. In the assessment of TEE, 11.8% had atrial septal aneurysm and 35.3% PFO. Mean LAA systolic velocity was 66.3 ± 20.3 cm / sec. There was no difference in systolic velocity of the LAA between patients with and without PFO (67.5 ± 11.8 cm / sec vs 65.7 ± 24.3 cm / sec respectively, p = 0.87). The control group of 8 patients, 5 women and 3 men, mean age 39.5 ± 18 years, had a LAA systolic velocity of 77.6 ± 28.9 cm / sec, no significant differences with ischemic patients. CONCLUSION There were no differences in systolic function of the LAA between patients with and without PFO with ischemic cerebrovascular event.

Abstract
Patent foramen ovale (PFO) is rapidly becoming in Europe, more than in the USA, a matter of over-diagnosis and over-treatment. A migrainous 34-year-old female with episodic hypostenia and even paralysis of the left arm was referred to a peripheral hospital for a complete neurological work-up. Being the Doppler ultrasound of carotid and vertebral arteries negative and angio-magnetic resonance imaging (MRI) positive for multiple white-matter lesions. A transthoracic echocardiography revealed a possible shunt through a patent foramen ovale with a right-to-left shunt and a mild buldging of interatrial septum, but the patient did not tolerate a further attempt of transesophageal echocardiography to confirm the diagnosis. Coagulation screening essay demonstrated a moderate hyperhomocisteinemia. In the hypothesis of embolic PFO mediated by a moderate prothrombotic state caused by hyperhomocisteinemia, the patient was referred to our attention for an attempt of PFO closure but on intracardiac echocardiography normal fossa ovalis without any shunt was revealed. One year later, during the follow-up, the patient became severely symptomatic for left arm hypostenia and parhestesia, both at rest and during efforts. Thus, the patient was submitted to a thoracic and upper limbs angio-MRI in order to exclude disease of the main arteries causing functional impotence. The MRI demonstrated thoracic outlet syndrome of both arms, more severe in the left arm with functional occlusion of the subclavian vein with abduction of the arm and possible cloth image at the subclavian vein next to the joint. The patient was referred to the thoracic surgeon for surgical repair.
