Abstract
Stroke is the most common cause of death and disability in the world, and ischemic etiology plays a major role. Atrial septal aneurysm (ASA) is a localized saccular deformity of the atrial septum, associated with ischemic stroke independently or in association with other atrial septal defects (ASD). There is a higher incidence of stroke in the population with ASD. In these patients, the presence of ASA is an important predictor of recurrent stroke. This is a case of ischemic stroke in a 44-year-old who presented with sudden-onset right-sided body weakness, expressive aphasia, and non-specific confusion for one hour, with an initial National Institutes of Health Stroke Scale (NIHSS) score of 7. CT angiogram revealed occlusion of the M3 branch of the left middle cerebral artery in the left lateral frontal lobe. Code stroke was called, and the patient was given tenecteplase (TNK), after which her right-side weakness and aphasia resolved. Trans-thoracic echo with bubble study showed ASA with positive bubble study. Lone ASA or ASA with concomitant ASD poses a higher risk of recurrent stroke in younger patients, especially those without significant risk factors for strokes. Patients with ASA and concomitant ASD are at high risk for recurrent ischemic stroke and should be kept under surveillance with continued medical therapy. We present a case of ischemic stroke caused by ASA and a review of the current literature and case reports documenting cases with similar presentations.

Abstract
Cardioembolic strokes account for 20-25% of all ischaemic strokes, with their incidence increasing with age. Cardiac imaging plays a crucial role in identifying cardioembolic causes of stroke, with early and accurate identification affecting treatment, preventing recurrence, and reducing stroke incidence. Echocardiography serves as the mainstay of cardiac evaluation. Transthoracic echocardiography (TTE) is the first line in the basic evaluation of structural heart disorders, valvular disease, vegetations, and intraventricular thrombus. It can be used to measure chamber size and systolic/diastolic function. Trans-oesophageal echocardiography (TOE) yields better results in identifying potential cardioembolic sources of stroke and should be strongly considered, especially if TTE does not yield adequate results. Cardiac computed tomography and cardiac magnetic resonance imaging provide better soft tissue characterisation, high-grade anatomical information, spatial and temporal visualisation, and image reconstruction in multiple planes, especially with contrast. These techniques are useful in cases of inconclusive echocardiograms and can be used to detect and characterise valvular lesions, thrombi, fibrosis, cardiomyopathies, and aortic plaques. Nuclear imaging is not routinely used, but it can be used to assess left-ventricular perfusion, function, and dimensions and may be useful in cases of infective endocarditis. Its use should be considered on a case-by-case basis. The accuracy of each imaging modality depends on the likely source of cardioembolism, and the choice of imaging approach should be tailored to individual patients.

Abstract
Cervical artery dissection (CAD) and Patent Foramen Ovale (PFO) are important causes of stroke in young patients. Although PFO is considered an independent risk factor for cerebral infarction in young adults with cryptogenic stroke, other concomitant causes may be necessary to cause brain injury. PFO could be a predisposing factor of stroke through several mechanisms including paradoxical embolism from a venous source, thrombus formation in atrial septum, or atrial arrhythmias causing cerebral thromboembolism. The pathophysiology of CAD is poorly understood and includes both constitutional and environmental factors. A causal association is often difficult to establish, as other predisposing factors may also play a role in CAD etiopathogenesis. We present a family with ischemic stroke (a father and his three daughters), in which the two different stroke causes are present. We hypothesized that a paradoxical embolism caused by PFO, associated with arterial wall disease, in the presence of a procoagulant state, could produce arterial dissection and then stroke.

Abstract
Patent foramen ovale (PFO) has been associated with cryptogenic stroke. There is conflicting data and it remains uncertain whether PFO is the direct cause, a risk factor or an incidental finding. Potential stroke mechanisms include paradoxical embolism from a venous clot which traverses the PFO, in situ clot formation within the PFO, and atrial arrhythmias due to electrical signaling disruption. Main risk factors linked with PFO-attributable strokes are young age, PFO size, right-to-left shunt degree, PFO morphology, presence of atrial septal aneurysm, intrinsic coagulation-anticoagulation systems imbalance, and co-existence of other atrial abnormalities, such as right atrial septal pouch, Eustachian valve and Chiari's network. These may act independently or synergistically, multiplying the risk of embolic events. The RoPE score, a scale that includes factors such as young age, cortical infarct location and absence of traditional stroke risk factors, is associated with the probability of a PFO being pathogenic and stroke recurrence risk after the index stroke. Multiple investigators have attempted to correlate other PFO features with the risk of PFO-related stroke, but further investigation is needed before any robust conclusions are reached. PFO presence in young patients with cryptogenic stroke should be considered as etiologically suspect. Caution should be exercised in interpreting the relevance of other PFO features.

Abstract
Aims:
Awareness of potentially embologenic diseases is critical to determining the prognosis of cryptogenic stroke. The clinical significance of atrial septal aneurysm (ASA) in cryptogenic stroke has not been fully studied. Therefore, we explored clinical characteristics and in-hospital recurrence in patients with ASA in cryptogenic stroke.
Methods:
A multicenter observational registry of cryptogenic stroke patients was conducted. We obtained baseline characteristics, radiological and laboratory findings, and echocardiographic findings, especially of embolic sources on transesophageal echocardiography. The CHALLENGE ESUS/CS (Mechanisms of Embolic Stroke Clarified by Transesophageal Echocardiography for embolic stroke of undetermined source/cryptogenic stroke) registry was recorded at http://www.umin.ac.jp/ctr/ (UMIN000032957). Patients’ clinical characteristics were compared according to the presence of ASA, and factors associated with in-hospital stroke recurrence were assessed.
Results:
The study included 671 patients (age, 68.7±12.7 years; 450 males; median National Institutes of Health Stroke Scale score, 2). ASA was detected in 92 patients (14%), displaying higher age (72.4±11.0 vs. 68.1 ±12.9 years,
p
=0.004), reduced frequency of diabetes mellitus (16% vs. 27%,
p
=0.030), higher frequency of right-to-left shunt (66% vs. 45%,
p
<0.001), and in-hospital stroke recurrence (8% vs. 3%,
p
=0.034). ASA was relatively associated with in-hospital recurrence (odds ratio 2.497, 95% confidence interval 0.959–6.500,
p
= 0.061).
Conclusions:
The CHALLENGE ESUS/CS registry indicated that ASA was not rare in cryptogenic stroke, and ASA’s clinical characteristics included higher age, reduced frequency of diabetes mellitus, and increased frequency of concomitant right-to-left shunt. ASA may be related to in-hospital stroke recurrence in cryptogenic stroke.

Abstract
Objective. This study aimed to assess the association of atrial septal aneurysm (ASA) with cardiac arrhythmias by comparing patients with ASA with a control group with non-ASA, matched for age and gender. Methods. 641 patients with ASA who fulfilled the inclusion criteria were enrolled into the study. The control group consisted of 641 patients without ASA. Patients underwent physical, electrocardiographic and transthoracic echocardiographic examinations. Additional examinations such as transesophageal echocardiography, 24-h rhythm Holter monitoring, and electrophysiological study were performed when clinically needed. Results. There were no differences between the groups in respect to baseline demographic, clinical parameters and echocardiographic parameters except ischemic stroke and smoking status. Percentages of patients suffering from atrial premature complex (APC), ventricular premature complex (VPC), supraventricular tachycardia (SVT) and paroxysmal atrial fibrillation (AF) were higher in ASA patients compared to non-ASA patients. In addition, these parameters were independently associated with the presence of ASA in logistic regression analysis. Conclusions. Certain types of arrhythmias such as APC, VPC, SVT and paroxysmal AF have been shown to be independently associated with the presence of ASA.

Abstract
BACKGROUND Three dimensional transesophageal echocardiography (3DTEE) is superior to two dimensional transesophageal echocardiography (2DTEE) as it provides all atrial septal information from a single view. AIM To evaluate 3DTEE role in analysis of atrial septal aneurysm (ASA) and in device closure guiding. METHODS Three dimensional transesophageal echocardiography were recorded with Vivid*E9,GE system over 14 months. ASAs were classified into 4 types (A: with PFO, B: with one ASD, C: with 2 ASDs, and D: with multiple fenestrations). Each aneurysm was assessed according to its type, shape, dimensions, orientation, aneurysmal tissue, and the surrounding rims. All patients passed to transcatheter aneurysm closure. RESULTS A total of 26 patients with ASAs were assessed (7 imperforated aneurysms excluded). The remaining 19 patients' age was 12.84 ± 5.82years. Four patients had type A aneurysms, 6 had type B, 4 had type C, and 5 had type D. 3DTEE demonstrated oval aneurysms in 17 patients. The orientation was oblique in 8 patients, vertical in 7, and horizontal in 4. The ASAs dimensions were 23.5 ± 5.1, 23.2 ± 5.1, and 22.0 ± 4.0 mm for oblique, vertical, and horizontal axes. Percutaneous closure succeeded in 18 patients. Balloon sizing was used in 4 patients. Devices used were: In type A:PFO devices, in type B:ASO devices, in type C:two patients required two ASO devices in each patient and two patients required one cribriform device, and in type D:Cribriform devices used for three patients, PFO for one and ASO for one. LA, LUPV, and RUPV approaches were used. Aspirin was received for 6 months. CONCLUSION Three dimensional transesophageal echocardiography helps to select aneurysms suitable for transcatheter closure, select the suitable devices, and guide the transcatheter procedure.

Abstract
Background Atrial septal aneurysm (ASA) is a congenital deformity of the interatrial septum with a prevalence of 1-2% in the adult population. Although ASA has been supposed to be an incidental finding in echocardiographic examination, its structural and clinical associations have gained an increasing interest. Aim To investigate and compare the clinical features and echocardiographic parameters between ASA patients and age- and gender-matched control group patients. Methods 410 patients with ASA were enrolled in the study, prospectively. After the exclusion of 33 patients, the remaining 377 patients comprised the study group. The control group consisted of 377 age- and gender-matched patients without ASA. Results Aortic valve regurgitation and mitral valve regurgitation were more often observed in patients with ASA, and percentages of patients with ascending aortic aneurysm (AAA), patent foramen ovale (PFO), and atrial septal defect (ASD) were higher in ASA patients compared to control group patients. Aortic root diameter was larger in ASA patients compared to control group patients (29.2 ± 3.9, 28.6 ± 3.1, p=0.05, respectively). Ascending aorta diameter was higher in ASA patients compared to patients without ASA (44 ± 0.3, 41.5 ± 0.2, p=0.02). Logistic regression analysis revealed that mitral valve regurgitation (OR: 2.05, 95% CI : 1.44–2.92, p < 0.001) and PFO (OR: 11.62, 95% CI : 2.64–51.02, p=0.001) were positively and independently associated with the presence of ASA. AAA tended to be statistically and independently associated with ASA (OR: 2.69, 95% CI : 0.97–7.47, p=0.05). Conclusions We have demonstrated a higher incidence of mitral/aortic valvular regurgitations, AAA, PFO, and ASD in ASA patients compared to age- and gender-matched control group patients. In addition, we have shown that ASA is significantly and positively associated with mild mitral regurgitation and PFO.

Abstract
BACKGROUND The optimal strategy of secondary stroke prevention in patients with patent foramen ovale (PFO) is controversial. This study was performed to evaluate the efficacy and safety of the device closure (DC) versus the medical therapy (MT) in patients with cryptogenic stroke or transient ischemic attack (TIA) and PFO. SUMMARY Randomized controlled trials with active and control groups receiving the DC plus MT and MT alone in patients with history of cryptogenic stroke/TIA and diagnosis of PFO were systematically searched. The main efficacy outcome was stroke recurrence. Subgroup-analyses were performed according to age, shunt size, and presence of atrial septal aneurysm (ASA). Safety endpoints included any serious adverse event (SAE), atrial fibrillation (AF), and major bleeding complications. Risk ratios (RRs) and hazard ratios (HRs) with 95% CIs were estimated. Five trials were included, involving 3,440 participants (DC = 1,829, MT = 1,611). There was a protective effect of closure in the risk of recurrent stroke (RR 0.43 [0.21-0.90]; p = 0.024; HR = 0.39 [0.19-0.83]; p = 0.014). The benefit of PFO closure was significant in patients with PFO associated with substantial right-to-left shunt or ASA. There were no differences in the risks of SAEs and major bleedings between the groups. The rate of new-onset AF was higher in the DC than in the MT arm (RR 4.46 [2.35-8.41]; p < 0.001). Successful device implantation and effective PFO closure were achieved in 96 and 91% of the patients respectively. Key Messages: In selected adult patients with PFO and history of cryptogenic stroke, the DC plus MT is more effective to prevent stroke recurrence and is associated with an increased risk of new-onset AF compared to the MT alone.

Abstract
Echocardiography is a powerful and convenient tool used routinely in the cardiac evaluation of many patients. Improved resolution and visualization of cardiac anatomy has led to the discovery of many normal variant structures that have no known pathologic consequence. Importantly, these findings may masquerade as pathology prompting unnecessary further evaluation at the expense of anxiety, cost, or potential harm. This review provides an updated and comprehensive collection of normal anatomic variants on both transthoracic and transesophageal imaging.

Abstract
PURPOSE We aimed to examine the incidence of patent foramen ovale (PFO) and atrial septal aneurysms (ASA) in the Turkish population using coronary computed tomography angiography (CTA); assess the feasibility of coronary CTA for PFO diagnosis by conducting a comparison with transthoracic echocardiography (TTE); and determine the diagnostic role and characteristics of the interatrial tunnel, free flap valve (FFV), and shunts. METHODS The present study was conducted retrospectively and included a sample of 782 patients. Coronary CTA results for all patients were evaluated for the following parameters: the presence of PFO, the degree of contrast jet (if present due to PFO), ASA existence, free flap valve (FFV) length, and PFO tunnel diameters (1 and 2). Coronary CTA and TTE results for PFO detection were also compared for 19 patients who underwent both procedures. RESULTS PFO was present in 118 patients (15%). In 19 patients who underwent both CTA and TTE, the shunt was present in 15 patients on TTE compared with nine patients on CTA. The sensitivity and specificity of CTA for shunt existence were 53% (8/15) and 75% (3/4), respectively. FFV was observed on CTA in 118 patients (15%). No significant relationship was observed between shunt existence and FFV length (P = 0.148), or between shunt existence and tunnel diameter-1 (P = 0.638) or diameter-2 (P = 0.058). ASAs were present in 16 patients (2%), while accompanying PFO was present in three patients (2.4%). CONCLUSION Coronary CTA constitutes a more practical and efficient alternative to TTE for PFO diagnosis. Further, it allows the clear visualization of anatomical details of the interatrial tunnel, shunts, and associated abnormalities and detects ASAs.

Abstract
Background and purpose Previous studies have suggested that atrial septal aneurysm is a potential risk factor for cerebral embolism. However, the association between the level of atrial septal protrusion and cerebral embolism is still unclear. The purpose of the present study was to assess the association between the maximal distance of atrial septal protrusion and cryptogenic stroke. Methods A total of 588 consecutive acute ischemic stroke patients (70 ± 11 (mean ± SD) years, 401 men) who underwent transesophageal echocardiography were enrolled. The maximal distance of atrial septal protrusion into the right or left atrium was measured. Atrial septal aneurysm was diagnosed when the maximal distance of atrial septal protrusion was >10 mm. Cryptogenic stroke was defined as non-lacunar ischemic stroke without >50% proximal artery stenosis or occlusion, cardioembolic sources, ≥4 mm atherosclerotic plaques in the aortic arch, or carotid or vertebral artery dissection. Results The rate of cryptogenic stroke increased with the increasing maximal distance of atrial septal protrusion. The maximal distance of atrial septal protrusion (multivariate-adjusted odds ratio (OR) per 1 mm, 1.14; 95% confidence interval (CI), 1.04-1.24; P = 0.003) and atrial septal aneurysm (multivariate-adjusted OR, 4.32; 95% CI, 1.22-20.39; P = 0.022) was independently associated with cryptogenic stroke. Conclusions The maximal distance of atrial septal protrusion was independently associated with cryptogenic stroke.

Abstract
Patients who have had a stroke are at high risk for recurrent stroke, myocardial infarction, and vascular death. Prevention of these events should be initiated promptly after stroke, because many recurrent events occur early, and should be tailored to the precise cause of stroke, which may require specific treatment. Lifestyle advice including abstinence from smoking, regular exercise, Mediterranean-style diet, and reduction of salt intake and alcohol consumption are recommended for all patients with stroke. For most patients with ischemic stroke or TIA, control of risk factors, including lowering blood pressure under 140/90mmHg and LDL cholesterol under 1g/L, together with antiplatelet or oral anticoagulant therapy, depending on the cause of stroke, have been shown to decrease the risk of recurrent stroke and cardiovascular events. Aspirin, clopidogrel, or the combination of aspirin and dipyridamole, are all acceptable options for secondary prevention in patients with ischemic stroke or TIA of arterial origin. Dual therapy with aspirin and clopidogrel might be considered for 3 weeks after a minor ischemic stroke or TIA and for 3 months in patients with stroke due to severe intracranial stenosis. Oral anticoagulants are very effective to prevent cardioembolic stroke. Non-VKA oral anticoagulants have a favorable risk-benefit profile compared with VKAs, with significant reductions in stroke, intracranial hemorrhage, mortality, with similar major bleeding, but increased gastrointestinal bleeding. Carotid endarterectomy reduces the risk of ipsilateral stroke in patients with recent (<6 months) non disabling ischemic stroke or TIA in the territory and severe carotid artery stenosis. Carotid stenting is a potential alternative to surgery in patients younger than ≈70 years or patients with greater risk of surgery due to anatomic or medical conditions or specific circumstances such as radiation-induced stenosis or restenosis after surgery. For patients with hemorrhagic stroke due to hypertension-associated small vessel disease or cerebral amyloid angiopathy, strict control of blood pressure is essential. Restarting oral anticoagulants in patients after intracranial hemorrhage is a difficult decision that should weigh the risks of recurrent ischemic and hemorrhage stroke with and without oral anticoagulants. Several areas of uncertainty persist including the optimal target of blood pressure in patients with cerebrovascular disease, the benefit of PFO closure in patients with PFO-associated stroke, of stenting procedures in patients with atherosclerotic intracranial artery or extracranial vertebral artery stenosis, and of interventional procedures in patients with brain arteriovenous or cavernous malformations.

Abstract
BACKGROUND Atrial septal aneurysm is a localized deformity of interatrial septum, generally at the level of fossa ovalis which protrudes into right or left atrium or both. The purpose of this study was to assess the frequency and covariates of atrial septal aneurysm in adult patients undergoing transthoracic echocardiography in our outpatient clinic. MATERIALS AND METHODS From December 2011 to May 2016, 16,570 patients were included in the study. Records of patients were retrospectively analyzed from our previously established database. All cardiovascular examinations and echocardiographical examinations had been done during this period. Briefly, protrusion of interatrial septum more than 15mm into the right or left atrium with an at least 15mm diameter base of interatrial septum confirmed the diagnosis of atrial septal aneurysm. RESULTS Atrial septal aneurysm has been documented in 393 patients (2.4%) in our study population. Mild to moderate mitral and aortic valve regurgitation have been demonstrated in 153 (39%) patients and in 61(16%) patients respectively. Sixty one (16%) of patients had the diagnosis of supraventricular arrhythmia of whom 52% underwent radiofrequency ablation procedure. CONCLUSION In conclusion we have documented that valvular regurgitation and supraventricular arrhythmias are common concurrent pathologies with atrial septal aneurysm.

Abstract
BACKGROUND Atrial septal aneurysms (ASAs) are uncommon but are associated with significant embolic morbidity when an interatrial communication is present. Although surgical reconstruction has traditionally been approached through a median sternotomy, minimally invasive techniques may be employed to reduce pain and recovery time. METHODS We present a video-assisted technique via right inframammary minithoracotomy utilizing peripheral cannulation for cardiopulmonary bypass. Included is a discussion of surgical tips, potential pitfalls and a description of unique technical aspects that differentiate atrial septal repair from other minimally invasive cardiac operations. RESULTS A complete repair of the defect was confirmed by intraoperative transesophageal echocardiography (TEE). The patient made an uncomplicated recovery and was discharged home within 48 hours of surgery. CONCLUSIONS Minimally invasive repair of an ASA utilizing peripheral cannulation for cardiopulmonary bypass and a right inframammary incision can be accomplished with satisfactory technical success and recovery time.

Abstract
Cerebrovascular disease is one of the most common causes of cerebrovascular morbidity and mortality in developed countries; up to 40% of acute ischemic strokes in young adults are cryptogenic in nature – that is, no cause is determined. However, in more than half of these patients, patent foramen ovale (PFO) is seen along with an increased incidence of atrial septal aneurysm (ASA). The following is a report of an interesting case: a 68-year-old man with ASA and transient cerebral ischemia. Transesophageal echocardiography (TEE) showed the presence of ASA; a test with microbubbles derived from a mixture of air and saline or colloids pointed out a shunt on the foramen ovale following Valsalva’s maneuver. The patient underwent percutaneous transcatheter closure of the interatrial communication by an interventional cardiologist. TEE and transcranial Doppler or TEE with the microbubbles test are the recommended methods for detecting and quantifying intracardiac shunts, both at rest and following Valsalva’s maneuver. In patients following the first event of transient ischemic attack, and without clinical and anatomical risk factors (such as the presence of ASA, PFO, and basal shunt), pharmacological treatment with antiplatelets or anticoagulants is closely recommended. On the contrary, in patients following the first event of transient ischemic attack, or a recurrent event during antiplatelet treatment, the percutaneous closure of PFO is recommended.

Abstract
BACKGROUND Paroxysmal supraventricular arrhythmias (SVAs) frequently occur in patients with atrial septal aneurysm (ASA). The aim of the current study was to evaluate the electrocardiographic (P-wave duration and dispersion) and echocardiographic (atrial electromechanical delay, AEMD) noninvasive indicators of atrial conduction heterogeneity in healthy ASA subjects without interatrial shunt and to assess the AEMD role in predicting the SVAs onset in this population. MATERIALS AND METHODS One hundered ASA patients (41 males, mean age of 32.5 ± 8 years) and 100 healthy subjects used as controls, matched for age and gender, were studied for the occurrence of SVAs during a 4-year follow-up, through 30-day external loop recorder (ELR) monitoring performed every 3 months. ASAs were diagnosed by transthoracic echocardiography based on the criteria of a minimal aneurismal base of ≥15 mm and an excursion of ≥10 mm. Intra-AEMD and inter-AEMD of both atria were measured through tissue Doppler echocardiography. P-wave dispersion (PD) was carefully measured using 12-lead electrocardiogram (ECG). RESULTS Compared to the healthy control group, the ASA group showed a statistically significant increase in inter-AEMD, intra-left AEMD, maximum P-wave duration, and PD. Dividing the ASA group into 2 subgroups (patients with or without SVAs), the inter-AEMD, intra-left AEMD, P max, and PD were significantly higher in the subgroup with SVAs compared to the subgroup without SVAs. There were significant good correlations of intra-left AEMD and inter-AEMD with PD. A cutoff value of 40.1 msec for intra-left AEMD had a sensitivity of 82% and a specificity of 83% in identifying ASA patients at risk for SVA. CONCLUSION Our results showed that the echocardiographic AEMD indices (intra-left and inter-AEMD) and the PD were significantly increased in healthy ASA subjects without interatrial shunt. PD and AEMD represent noninvasive, inexpensive, useful, and simple parameters to assess the SVAs' risk in ASA patients.

Abstract
The clinical significance of persistent patent foramen ovale (PFO) is not well defined. Empirically, PFO has been associated with many clinical conditions. In cryptogenic stroke, migraine, and orthodeoxia/platypnea, a plausible biologic mechanism exists to support PFO closure as a possible treatment. Although transcatheter closure of PFO has been available for over 2 decades, it has remained controversial due to a paucity of evidence to guide patient and device selection. Contemporary studies investigating PFO closure as treatment for patients with these conditions have been published recently and longitudinal data regarding the safety and efficacy of the devices is now available. In this review, we aim to describe the potential clinical significance of a patent foramen in the adult, appraise the newest additions to the body of evidence, and discuss the safety, benefit, patient selection, and future of transcatheter treatment of PFO.

Abstract
OBJECTIVES This study sought to investigate the prevalence of atrial septal aneurysms in the paediatric population and to define coexisting abnormalities and their incidence. BACKGROUND Few papers refer to the prevalence of atrial septal aneurysms in childhood. METHODS We enrolled a total of 4522 children aged more than 12 months who underwent a transthoracic echocardiography. Atrial septal aneurysm was defined as a protrusion of the interatrial septum or part of it >15 mm beyond the plane of the atrial septum or phasic excursion of the interatrial septum during the cardiorespiratory cycle of at least 15 mm in total amplitude and a diameter of the base of the aneurysm of at least 15 mm. RESULTS Atrial septal aneurysms were found in 47 children (1.04%). They involved almost the entire septum in 14 patients (28.89%) and were limited to the fossa ovalis in 33 (71.11%). An atrial septal aneurysm was an isolated structural defect in 17 (35.56%). In 30 (64.44%) patients, it was associated with interatrial shunting - atrial septal defect and patent foramen ovale. At the echo follow-up after a year, no changes were recorded. CONCLUSIONS Prevalence of atrial septal aneurysms is almost 1%. The most common abnormalities associated are interatrial shunts, that is, a patent foramen ovale and an atrial septal defect. From a medical point of view, it is suggested that no action is to be taken during childhood, as a child with an atrial septal aneurysm is not at increased risk compared with a child without one. Follow-up is scheduled on an individual basis.

Abstract
Cryptogenic (of unknown cause) ischaemic strokes are now thought to comprise about 25% of all ischaemic strokes. Advances in imaging techniques and improved understanding of stroke pathophysiology have prompted a reassessment of cryptogenic stroke. There is persuasive evidence that most cryptogenic strokes are thromboembolic. The thrombus is thought to originate from any of several well established potential embolic sources, including minor-risk or covert cardiac sources, veins via paradoxical embolism, and non-occlusive atherosclerotic plaques in the aortic arch, cervical, or cerebral arteries. Accordingly, we propose that embolic strokes of undetermined source are a therapeutically relevant entity, which are defined as a non-lacunar brain infarct without proximal arterial stenosis or cardioembolic sources, with a clear indication for anticoagulation. Because emboli consist mainly of thrombus, anticoagulants are likely to reduce recurrent brain ischaemia more effectively than are antiplatelet drugs. Randomised trials testing direct-acting oral anticoagulants for secondary prevention of embolic strokes of undetermined source are warranted.

Abstract
OBJECTIVES To provide a comprehensive comparison of patent foramen ovale (PFO) closure versus medical therapy in patients with cryptogenic stroke or transient ischaemic attack (TIA) and demonstrated PFO. DESIGN Systematic review with complete case meta-analysis and sensitivity analyses. Data sources included MEDLINE and EMBASE from 1980 up to May 2013. All randomised controlled trials (RCTs) comparing treatment with percutaneous catheter-based closure of PFO to anticoagulant or antiplatelet therapy in patients with cryptogenic stroke or TIA and echocardiographically confirmed PFO or atrial septal defect (ASD) were eligible. PARTICIPANTS 1967 participants with prior stroke or TIA and echocardiographically confirmed PFO or ASD. PRIMARY OUTCOME MEASURES The primary outcome of interest was recurrence of ischaemic stroke. We utilised data from complete cases only for the primary endpoint and combined data from trials to estimate the pooled risk ratio (RR) and associated 95% CIs calculated using random effects models. RESULTS We identified 284 potentially eligible articles of which three RCTs including 2303 patients proved eligible and 1967 patients had complete data. Of the 1026 patients randomised to PFO closure and followed to study conclusion 22 experienced non-fatal ischaemic strokes, as did 34 of 941 patients randomised to medical therapy (risk ratio (RR) 0.61, 95% CI 0.34 to 1.07; heterogeneity: p=0.34, I(2)=8%, confidence in estimates low due to risk of bias and imprecision). Analyses for ischaemic stroke restricted to 'per-protocol' patients or patients with concomitant atrial septal aneurysm did not substantially change the observed RRs. Complication rates associated with either PFO closure or medical therapy were low. CONCLUSIONS Pooled data from three RCTs provides insufficient support that PFO closure is preferable to medical therapy for secondary prevention of cryptogenic stroke in patients with PFO.

Abstract
BACKGROUND The cardiovascular vulnerability of young adults who were born preterm was first acknowledged over a decade ago. AIMS (1) To examine the echocardiographic characteristics of a group of young adults born preterm with an extremely low birthweight (<1000 g; ex-ELBW) in comparison with healthy controls born at term (C); (2) to identify a correlation between the potential echocardiographic abnormalities detected in ex-ELBW and their anthropometric parameters, age, presence of respiratory distress, patency of ductus arteriosus, length of stay in Neonatal Intensive Care Unit. METHODS Thirty-seven ex-ELBW (11 males, 26 females; mean age: 22.2 ± 1.8 years) were compared with 37 C (11 males, 26 females). Both groups underwent standard mono- and bi-dimensional transthoracic echocardiogram with color Doppler. RESULTS No statistically significant differences were detected between the two groups regarding mono-dimensional echocardiography or Doppler measurements (p = ns). Conversely, a statistically significant difference was observed between the prevalence of interatrial septal aneurysm (ASA) in ex-ELBW compared to C (p = 0.0016). A significant association was likewise observed between ASA and the presence of both respiratory distress at birth (p < 0.05) and patency of the ductus arteriosus (p < 0.05). CONCLUSIONS A significant prevalence of ASA was detected in ex-ELBW subjects compared to C, underlining a probable correlation with respiratory distress and patent ductus arteriosus. In view of the association between ASA and stroke in young adults devoid of other cerebrovascular risk factors, this unexpected observation suggests that all ex-preterm subjects should undergo transthoracic or transesophageal echocardiographic examination with the aim of detecting this potentially emboligenic cardiac abnormality.

Abstract
A 41-year-old male with a history of human immunodeficiency virus (HIV) infection developed motor aphasia, dysarthria, and right hemiparesis. A magnetic resonance imaging scan of the brain revealed a cerebral infarction in the territory of the left middle cerebral artery. The laboratory data showed decreased levels of protein S and protein C. Transesophageal contrast-enhanced echocardiography revealed a patent foramen ovale (PFO). Prothrombotic states, such as protein S and C deficiency, have been reported in HIV-infected patients. In addition, previous studies have reported prothrombotic states to be risk factors for PFO-related cerebral infarction. An association between combined protein S and C deficiency caused by HIV infection and PFO-related cerebral infarction was suggested in our patient.

Abstract
OPININION STATEMENT: All patients with ischemic stroke should undergo a comprehensive assessment of cardiovascular risk. Patients with carotid artery disease, symptoms of cerebral ischemia and high cardiovascular risk profiles should be considered for noninvasive testing for coronary artery disease (CAD). Routine testing for CAD before carotid endarterctomy is not recommended. Patients with coexisting coronary and carotid artery disease should be more aggressively treated for reducing their "very high" risk of cardiovascular events. In patients candidates to carotid revascularization, a preoperative coronary angiography and coronary revascularization are not recommended. Warfarin is recommended in all patients with moderate to high risk of stroke. Novel oral anticoagulants represent an attractive alternative to warfarin. However, their place in therapy in clinical practice is not yet established. Percutaneous closure of the left atrial appendage for stroke prophylaxis may be considered in selected patients with atrial fibrillation and contraindications for oral anticoagulant therapy. Warfarin is not indicated in patients with heart failure who are in sinus rhythm. Percutaneous closure of patent foramen does not seem to be superior to medical therapy for the prevention of recurrences in patients with cryptogenic stroke.

Abstract
Our patient presented to a large university teaching hospital with a history of light-headedness, falls and multiple cerebrovascular ischaemic events. This caused a right sided hemiplegia and the patient experienced significant functional limitation. Extensive investigations were carried out to exclude any causative factors such as carotid artery disease and the patient had all identifiable cardiovascular risk factors identified and modified. No significant pathology was found and a referral was made to the cardiology service. Transthoracic echocardiography revealed a complex type 3 perforate 'pepper pot' atrial septal aneurysm with associated thrombus. The patient was commenced on warfarin and appropriate rate limiting medication. After discussion of all interventional modalities, the patient opted for conservative management.

Abstract
OBJECTIVE To identify whether factors supporting a diagnosis of paradoxical embolism (i.e., venous thrombosis or Valsalva maneuver) are associated with radiologic markers of recurrent strokes in patients with patent foramen ovale (PFO) and cryptogenic stroke (CS). Such clinical indicators of paradoxical embolism are commonly viewed as risk factors for CS recurrence, but precise risk estimates are lacking. METHODS Data from the prospective Tufts PFO Registry collected at the time of the index CS were analyzed. We defined the following radiologic markers of stroke recurrence: 1) strokes of different radiologic ages and 2) silent strokes (detected on MRI but without symptoms preceding the index event). We examined the association between the radiologic endpoints and the clinical indicators of paradoxical embolism with multivariate logistic regression models, adjusting for age and gender. RESULTS Data were available for 224 subjects. Strokes of different radiologic ages were not associated with the thrombosis-predisposing conditions (1.2 [95% confidence interval 0.5-2.7]), the Valsalva maneuver (1.3 [0.6-3.1]), or the presence of either of these factors. No statistically significant association was found in subgroups stratified by anatomic location of the index stroke or for the outcome of silent strokes. CONCLUSIONS Our negative findings do not lend support to using the presence of clinical indicators of paradoxical embolism as an indication for percutaneous PFO closure. Factors that support a paradoxical embolism mechanism may be different from those that predict paradoxical embolism recurrence. Further investigations with clinical follow-up and larger sample sizes are needed to reach more precise estimates for the associations examined.

Abstract
Ischemic stroke in younger people is common, and often remains unexplained. There is a well-documented association between unexplained stroke in younger people, and the presence of a patent foramen ovale. Therefore, in the absence of a clear cause of stroke, the heart is often assessed in detail for such lower risk causes of stroke. This usually involves imaging with a transesophageal echo, and investigation for a right-to-left shunt. An understanding of the anatomy of the atrial septum, and its associated abnormalities, is important for the stroke neurologist charged with decision making regarding appropriate secondary prevention. In this paper, we review the development and anatomy of the right heart with a focus on patent foramen ovale, and other associated abnormalities. We discuss how the heart can be imaged in the case of unexplained stroke, and provide examples. Finally, we suggest a method of investigation, in light of the recent European Association of Echocardiography guidance. Our aim is to provide the neurologist with an understanding on how the heart can be investigated in unexplained stroke, and the significance of abnormalities detected.

Abstract
BACKGROUND Antithrombotic therapy in valvular disease is important to mitigate thromboembolism, but the hemorrhagic risk imposed must be considered. METHODS The methods of this guideline follow those described in Methodology for the Development of Antithrombotic Therapy and Prevention of Thrombosis Guidelines. Antithrombotic Therapy and Prevention of Thrombosis, 9th ed: American College of Chest Physicians Evidence-Based Clinical Practice Guidelines in this supplement. RESULTS In rheumatic mitral disease, we recommend vitamin K antagonist (VKA) therapy when the left atrial diameter is > 55 mm (Grade 2C) or when complicated by left atrial thrombus (Grade 1A). In candidates for percutaneous mitral valvotomy with left atrial thrombus, we recommend VKA therapy until thrombus resolution, and we recommend abandoning valvotomy if the thrombus fails to resolve (Grade 1A). In patients with patent foramen ovale (PFO) and stroke or transient ischemic attack, we recommend initial aspirin therapy (Grade 1B) and suggest substitution of VKA if recurrence (Grade 2C). In patients with cryptogenic stroke and DVT and a PFO, we recommend VKA therapy for 3 months (Grade 1B) and consideration of PFO closure (Grade 2C). We recommend against the use of anticoagulant (Grade 1C) and antiplatelet therapy (Grade 1B) for native valve endocarditis. We suggest holding VKA therapy until the patient is stabilized without neurologic complications for infective endocarditis of a prosthetic valve (Grade 2C). In the first 3 months after bioprosthetic valve implantation, we recommend aspirin for aortic valves (Grade 2C), the addition of clopidogrel to aspirin if the aortic valve is transcatheter (Grade 2C), and VKA therapy with a target international normalized ratio (INR) of 2.5 for mitral valves (Grade 2C). After 3 months, we suggest aspirin therapy (Grade 2C). We recommend early bridging of mechanical valve patients to VKA therapy with unfractionated heparin (DVT dosing) or low-molecular-weight heparin (Grade 2C). We recommend long-term VKA therapy for all mechanical valves (Grade 1B): target INR 2.5 for aortic (Grade 1B) and 3.0 for mitral or double valve (Grade 2C). In patients with mechanical valves at low bleeding risk, we suggest the addition of low-dose aspirin (50-100 mg/d) (Grade 1B). In valve repair patients, we suggest aspirin therapy (Grade 2C). In patients with thrombosed prosthetic valve, we recommend fibrinolysis for right-sided valves and left-sided valves with thrombus area < 0.8 cm(2) (Grade 2C). For patients with left-sided prosthetic valve thrombosis and thrombus area ≥ 0.8 cm(2), we recommend early surgery (Grade 2C). CONCLUSIONS These antithrombotic guidelines provide recommendations based on the optimal balance of thrombotic and hemorrhagic risk.

Abstract
BACKGROUND Interatrial septal anomalies, which include atrial septal defect, patent foramen ovale, and atrial septal aneurysm, are common disorders among adult patients. Early detection of interatrial septal anomalies is important in order to prevent haemodynamic consequences and/or thromboembolic events. Electrocardiogram offers some clues that should serve as hints for detection of interatrial abnormalities. The aim of our study was to analyse the interatrial septum by transoesophageal echocardiography in patients with electrocardiogram signs of right bundle branch block and in those without right bundle branch block. METHODS AND RESULTS In a prospective study, 87 adult patients were included, that is, 41 with electrocardiogram signs of right bundle branch block forming the first group and 46 without right bundle branch block forming the second group. Interatrial septal anomalies were present in 80.5% of the patients with right bundle branch block, with patent foramen ovale (39.02%) being the most prevalent disorder, followed by atrial septal aneurysm (21.9%) and atrial septal defect (19.5%). Interatrial septal abnormalities were significantly more frequent in the first group compared with the second group (80.5% versus 6.5%, p value less than 0.001). Independently, patent foramen ovale was significantly more prevalent in patients with right bundle branch block (39.02% versus 4.3%, p value less than 0.001), as were atrial septal aneurysm (21.9% versus 2.2%, p value equal 0.01) and atrial septal defect (19.5% versus 0%, p value equal 0.004). CONCLUSIONS Right bundle branch block should serve as a valuable indicator to motivate a detailed search for interatrial septal abnormalities.

Abstract
BACKGROUND Although an atrial myxoma is the commonest cardiac tumor, it is still relatively rare, with an annual incidence of approximately 0.5 per million. In our unit, which performs 1000 major cardiac procedures per year, this equates to approximately 3 patients annually. We therefore sought to evaluate our experience of managing this type of tumor over the last 5 years. METHODS A retrospective review was performed of prospectively collected data from the departmental database. We analyzed consecutive patients who were operated upon between 2002 and 2007. Three patients with a papillary fibroelastoma on histological examination were excluded from this study. RESULTS We have performed excision of atrial myxoma in 18 patients. Twelve patients (66%) were female; the median age was 64 years (range, 35-80 years), and the median logistic euroSCORE was 5.22% (range, 1.51-27.82%). Fifteen patients (83%) were deemed urgent, 2 elective, and 1 emergency. Sixteen tumors (89%) were left sided. Symptoms attributable to the tumor were found in 16 of the 18 patients (embolic, n = 9; chest pain, n = 3; palpitations, n = 2; incidental finding, n = 2, others n = 4), and the mean time from diagnosis to operation was 3 days (range, 0-22 months). The median cardiopulmonary bypass time was 87 minutes (range, 28-228 minutes), with the median aortic cross clamp time being 61 minutes (16-175 minutes).The approaches used were transeptal via right atriotomy (n = 8), biatrial/Dubost (n = 4), left atrial (n = 4), and right atrial (n = 2); the interatrial septum was involved in 14 patients. The resultant defect was closed using a pericardial (n = 8) or prosthetic patch (n = 5) or directly sutured (n = 5). Concomitant procedures were performed in 8 patients (coronary artery bypass graft [CABG], n = 4; mitral valve replacement [MVR], n = 2; valve + grafts, n = 2). All tumors were completely excised.Postoperatively there were no deaths within 30 days of the procedure. Indeed, only 2 patients have died at 4 and 25 months postoperatively, respectively, both of unrelated causes. Median intensive therapy unit (ITU) stay was 2 days (range, 1-9 days), and median hospital stay was 10 days (range, 5-20 days). A permanent pacemaker was required in only 1 patient, and median blood loss was 340 mL (range, 140-1760 mL). Atrial fibrillation was the commonest complication affecting 6/18 patients (33%). CONCLUSIONS Excision of atrial myxoma can be performed using a variety of intraoperative approaches and closure techniques, all with acceptable postoperative morbidity and low mortality rates. To date, no recurrences have been found at median 2-year follow-up.

Abstract
OBJECTIVE The aim of the study was to investigate the relationship between atrial septal aneurysms (ASAs) and cardiac arrhythmias via signal-averaged P-wave duration (SAPWD) and P-wave dispersion (Pd). METHODS Sixty-six patients with ASA served as the study group (group 1; 28 men and 38 women; mean age, 34 +/- 10 years) and 62 healthy volunteers served as the control group (group 2; 29 men and 33 women; mean age, 31 +/- 8 years) in the current study. ASAs were diagnosed by transthoracic echocardiography based on the criteria of a minimal aneurysmal base of > or =15 mm; and an excursion of > or =10 mm. All subjects were evaluated by 24-hour Holter monitoring, 12 lead body surface electrocardiogram for P-wave analysis, and signal-averaged electrocardiogram for P-wave duration (PWD). RESULTS There was no significant difference between the study and control groups in terms of age, gender, left atrium diameter, and left ventricular ejection fraction. Supraventricular arrhythmias (SVAs) were detected in 29 patients with ASA (43.9%) and 5 controls (8.1%; P < 0.001). The mean Pd in patients with ASA was significantly longer compared to the control group (14.1 +/- 8 ms vs 7.0 +/- 2.9 ms; P < 0.001). Similarly, the mean SAPWD in group 1 was significantly longer compared to group 2 (127.4 +/- 17.6 ms vs 99.8 +/- 12.3 ms; P < 0.001). CONCLUSION Prolonged SAPWD and Pd were determined to indicate electrical disturbances in the atrial myocardium, and predict the increase in the prevalence of SVA in patients with ASA.

Abstract
Atrial septal aneurysm (ASA) is a saccular deformity located in the atrial septum. Atrial arrhythmias are common in patients with ASA. Atrial electromechanical delay (AEMD) can be used to evaluate development of atrial arrhythmias in various settings. The aim of the study was to investigate the relationship between ASA, cardiac arrhythmias and AEMD. Seventy patients with ASA served as the study group (30 men; mean age, 33.6 ± 10.9 years) and 70 healthy volunteers served as the control group (34 men; mean age, 31.4 ± 7.8 years). ASAs were diagnosed by transthoracic echocardiography based on the criteria of a minimal aneurysmal base of ≥ 15 mm; and an excursion of ≥ 10 mm. Inter-AEMD and intra-AEMDs of both atrium were measured from parameters of tissue Doppler imaging. There was no significant difference between the study and control groups in terms of age, gender, left atrium diameter, and left ventricular ejection fraction. Inter-AEMD (50.7 ± 22.5 ms vs. 36.9 ± 12.0 ms) and intra-left AEMD (44.6 ± 17.4 ms vs. 30.7 ± 11.6 ms) were significantly higher in patients with ASA with respect to control group. Inter-AEMD (63.6 ± 20.1 ms vs. 45.1 ± 21.5 ms, P = 0.001), intra-left AEMD (55.3 ± 15.6 ms vs. 40.1 ± 16.2 ms, P = 0.001), diameter of the ASA (19.9 ± 3.6 mm vs. 17.1 ± 2.7 mm, P = 0.001) and P wave dispersion (18.5 ± 6.7 ms vs. 11.8 ± 7.3 ms, P = 0.001) were significantly greater in the subgroup with arrhythmias compared to the subgroup without arrhythmias. Inter-AEMD and intra-left AEMD were found to be significantly prolonged in patients with ASA. Being a non-invasive, inexpensive and simple technique AEMD may provide significant contributions to assess the risk for paroxysmal supraventricular arrhythmia in patients with ASA.

Abstract
Stroke in young adults is not a rare entity, and often provides difficult management decisions for neurologists. The knowledge gained from stroke in older adults does not transfer easily to this younger group given the different causes of stroke observed. Cardiac causes of stroke are common in this group, but often consist of low risk cardiac lesions such as a patent foramen ovale. Appropriate investigation should follow a stepwise approach to initially exclude higher risk pathology for recurrent stroke such as arterial dissection. Similarly, stepwise application of cardiac investigations will allow early identification of significant pathology, with investigation for abnormalities of the inter-atrial septum reserved for those with no other identified cause of stroke. Bubble contrast echo is now widely available, and with improved image quality may be performed with either transthoracic or transoesophageal echo, as well as with transcranial Doppler. Following this approach, patients can be best categorised by the expected rate of recurrent stroke, as informed by observational studies. Appropriate secondary prevention can then be tailored to the recurrence rate, with anticoagulation and possibly device closure reserved for those at highest risk of recurrence.

Abstract
Apart from their existence as medical curiosities, anatomic variants also double as diagnostic dilemmas. In the heart, more than in any other location in the body, misinterpretation of normal anatomic variants as pathologic entities can have a profound impact on treatment decisions and clinical consequences. Echocardiography is an easily accessible tool these days and is used routinely in most cardiac evaluations. Thus it becomes imperative for the echocardiographer to be cognizant of normal anatomic variants. Furthermore, echocardiographic findings should always be evaluated in their proper clinical context and diagnoses should never be entertained in a clinical vacuum. The literature is replete with numerous case reports and vignettes on these fascinating structures but is lacking in a formal review of normal anatomic variants. In this article, we have attempted a systemic review of normal variants, their embryologic origins, echocardiographic characteristics, and common pitfalls encountered in their evaluation.
