Front Cardiovasc Med 2023; 10:1249259. [PMID: 37900574 PMCID: PMC10611517 DOI: 10.3389/fcvm.2023.1249259] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 06/28/2023] [Accepted: 09/27/2023] [Indexed: 10/31/2023] Open
Abstract
Introduction Patent foramen ovale (PFO) closure is performed in selected patients with cryptogenic stroke to prevent recurrence. The prognosis of patients with uncrossable PFO after failed guidewire or catheter passage during the procedure remains unknown. We compared the long-term prognosis between uncrossable PFO and successful PFO closure in patients with high-grade PFO shunts. Methods We analyzed patients who underwent PFO closure for stroke or transient ischemic attack (TIA) prevention at Gachon University Gil Medical Center between April 2010 and March 2022. The primary outcome was a composite of recurrent stroke or TIA. Secondary outcomes included stroke, TIA, all-cause death, and a composite of stroke, TIA, and all-cause death. Results Of 286 patients, 245 were included in the analysis after excluding those with transseptal puncture technique usage or concurrent atrial septal defect. Among them, 82 had uncrossable PFO, and 163 underwent successful PFO closure. Large shunts were more prevalent in the PFO closure group compared to the uncrossable PFO group (62.0% vs. 34.1%, P < 0.001), and resting shunts were also more common in the PFO closure group (17.8% vs. 2.4%, P < 0.001). Stroke or TIA occurred in 2 patients (2.4%) in the uncrossable PFO group and 8 patients (4.9%) in the PFO closure group (hazard ratio, 1.44; 95% confidence interval, 0.30-6.81; P = 0.647). Additionally, no disparities in the occurrence of stroke or TIA were found in subgroups divided by baseline characteristics, RoPE score, or shunt grade. Conclusion Clinical outcomes for patients with uncrossable PFO seem similar to those with successful PFO closure.

Abstract
The presence of patent foramen ovale (PFO) is noted to be higher in patients with a history of cryptogenic stroke, especially in younger patients <55 years old. PFO has shown to be a relatively common occurrence in the population, in 25-30% of individuals. Our case is one of right middle cerebral artery (MCA) infarct due to thromboembolism from a PFO. A 44-year-old white right-handed woman with a history of insulin-dependent diabetes mellitus, hyperlipidemia, hypertension, tobacco abuse, and obesity presented with complaints of new onset headache, dizziness, and left arm and leg heaviness, suspicious for right MCA lesion. She was admitted with stroke-like symptoms, National Institute of Health Stroke Scale (NIHSS) of 8 for left-sided weakness, sensory loss, and ataxia. Computed tomography (CT) head was negative for hemorrhage, and there was no large vessel occlusion on computed tomography angiogram (CTA). She was aspirin-loaded and started on dual antiplatelet therapy (DAPT). Ultimately, brain MRI showed right MCA ischemic stroke, and full stroke assessment showed small PFO on the transthoracic echocardiogram (TTE). She was continued on aspirin and clopidogrel DAPT for 21 days, followed by aspirin monotherapy. Unfortunately, her left-sided deficits did not completely resolve, and she was discharged to rehab. She has had recurrent stroke and is currently considered for PFO repair. A patient's past medical history, last known well time, and exacting symptoms with the NIHSS at onset should be thoroughly obtained at the first medical contact. CT imaging should rule out hemorrhage prior to prompt antiplatelet or thrombolytic administration. In addition, when there are absence of risk factors and the cause remains unknown, it is especially important to obtain TTE with Doppler to assess for right-to-left atrial shunt indicating PFO and potentially contributing thromboembolic etiology. Stroke precautions involving swallow evaluation, aspiration and fall precautions, serial NIH for changes, sequence of imaging, and physical therapy (PT) and occupational therapy (OT) should entail. A stroke neurologist should also be involved at presentation, with the stroke alert protocol shown to improve patient outcomes. Additional risk factors, such as PFO, should also be addressed, often with a multimodal team of providers and careful weight given to the risks and benefits of invasive procedure.

Transesophageal echocardiography-guided versus fluoroscopy-guided patent foramen ovale closure: A single center registry. Echocardiography 2023. [PMID: 37248818 DOI: 10.1111/echo.15630] [Citation(s) in RCA: 2] [Impact Index Per Article: 2.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 02/28/2023] [Revised: 05/11/2023] [Accepted: 05/21/2023] [Indexed: 05/31/2023] Open
Abstract
BACKGROUND Percutaneous closure of patent foramen ovale (PFO) is conventionally performed under continuous transesophageal echocardiographic (TEE) guidance. We aimed to evaluate whether a simplified procedural approach, including pure fluoroscopy-guidance and final TEE control, as well as an aimed 'next-day-discharge' is comparable with the conventional TEE-guided procedure in terms of periprocedural and intermediate-term outcomes. METHODS All patients who underwent a PFO closure at our center between 2010 and 2022 were retrospectively included. Prior to June 2019 cases were performed with continuous TEE guidance (TEE-guided group). Since June 2019, only pure fluoroscopy-guided PFO closures have been performed with TEE insertion and control just prior to device release (fluoroscopy-guided group). We analyzed procedural aspects, as well as long term clinical and echocardiographic outcomes. RESULTS In total 291 patients were included in the analysis: 197 in the TEE-guided group and 94 in the fluoroscopy-guided group. Fluoroscopy-guided procedures were markedly shorter (48 ± 20 min vs. 25 ± 9 min; p < .01). There was no difference in procedural complications, including death, major bleeding, device dislodgement, stroke or clinically relevant peripheral embolization between the two groups (.5% vs. 0%; p = .99). Hospital stay was also shorter with the simplified approach (2.5 ± 1.6 vs. 3.5 ± 1.2 days; p < .01), allowing 85% same-day discharges during the last 12 months of observation period. At 6 ± 3 months echocardiographic follow-up a residual leakage was described in 8% of the TEE-guided cases and 2% of the fluoroscopy-guided cases (p = .08). CONCLUSION While a complete TEE-free PFO closure might have potential procedural risks, our approach of pure fluoroscopy-guided with a brisk final TEE check seems to be advantageous in terms of procedural aspects with no sign of any acute or intermediate-term hazard and it could offer an equitable compromise between the two worlds: a complete TEE procedure and a procedure without any TEE.

Diagnostic Performance of Cardiac Computed Tomography for Detecting Patent Foramen Ovale: Evaluation Using Transesophageal Echocardiography and Catheterization as Reference Standards. J Cardiovasc Dev Dis 2023; 10:jcdd10050193. [PMID: 37233160 DOI: 10.3390/jcdd10050193] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 04/04/2023] [Revised: 04/19/2023] [Accepted: 04/24/2023] [Indexed: 05/27/2023] Open
Abstract
BACKGROUND Patent foramen ovale (PFO) is associated with various diseases such as cryptogenic stroke, migraine, and platypnea-orthodeoxia syndrome. This study aimed to evaluate the diagnostic performance of cardiac computed tomography (CT) for PFO detection. MATERIALS AND METHODS Consecutive patients diagnosed with atrial fibrillation and who underwent catheter ablation with pre-procedural cardiac CT and transesophageal echocardiography (TEE) were enrolled in this study. The presence of PFO was defined as (1) the confirmation of PFO using TEE and/or (2) the catheter crossing the interatrial septum (IAS) into the left atrium during ablation. CT findings indicative of PFO included (1) the presence of a channel-like appearance (CLA) on the IAS and (2) a CLA with a contrast jet flow from the left atrium to the right atrium. The diagnostic performance of both a CLA alone and a CLA with a jet flow was evaluated for PFO detection. RESULTS Altogether, 151 patients were analyzed in the study (mean age, 68 years; men, 62%). Twenty-nine patients (19%) had PFO confirmed by TEE and/or catheterization. The diagnostic performance of a CLA alone was as follows: sensitivity, 72.4%; specificity, 79.5%; positive predictive value (PPV), 45.7%; negative predictive value (NPV), 92.4%. The diagnostic performance of a CLA with a jet flow was as follows: sensitivity, 65.5%; specificity, 98.4%; PPV, 90.5%; NPV, 92.3%. The diagnostic performance of a CLA with a jet flow was statistically superior to that of a CLA alone (p = 0.045), and the C-statistics were 0.76 and 0.82, respectively. CONCLUSION A CLA with a contrast jet flow in cardiac CT has a high PPV for PFO detection, and its diagnostic performance is superior to that of a CLA alone.

Detection of patent foramen ovale in patients with ischemic stroke on prospective ECG-gated cardiac CT compared to transthoracic echocardiography. J Neurol 2023:10.1007/s00415-023-11688-0. [PMID: 37027020 DOI: 10.1007/s00415-023-11688-0] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Journal Information] [Subscribe] [Scholar Register] [Received: 01/10/2023] [Revised: 03/23/2023] [Accepted: 03/25/2023] [Indexed: 04/08/2023]
Abstract
BACKGROUND Cardiac CT acquired during the acute stroke imaging protocol is an emerging alternative to transthoracic echocardiography (TTE) to screen for sources of cardioembolism. Currently, its diagnostic accuracy to detect patent foramen ovale (PFO) is unclear. METHODS This was a substudy of Mind the Heart, a prospective cohort in which consecutive adult patients with acute ischemic stroke underwent prospective ECG-gated cardiac CT during the initial stroke imaging protocol. Patients also underwent TTE. We included patients < 60 years who underwent TTE with agitated saline contrast (cTTE) and assessed sensitivity, specificity, negative and positive predictive value of cardiac CT for the detection of PFO using cTTE as the reference standard. RESULTS Of 452 patients in Mind the Heart, 92 were younger than 60 years. Of these, 59 (64%) patients underwent both cardiac CT and cTTE and were included. Median age was 54 (IQR 49-57) years and 41/59 (70%) were male. Cardiac CT detected a PFO in 5/59 (8%) patients, 3 of which were confirmed on cTTE. cTTE detected a PFO in 12/59 (20%) patients. Sensitivity and specificity of cardiac CT were 25% (95% CI 5-57%) and 96% (95% CI 85-99%), respectively. Positive and negative predictive values were 59% (95% CI 14-95) and 84% (95% CI 71-92). CONCLUSION Prospective ECG-gated cardiac CT acquired during the acute stroke imaging protocol does not appear to be a suitable screening method for PFO due to its low sensitivity. Our data suggest that if cardiac CT is used as a first-line screening method for cardioembolism, additional echocardiography remains indicated in young patients with cryptogenic stroke, in whom PFO detection would have therapeutic consequences. These results need to be confirmed in larger cohorts.

Abstract
BACKGROUND Sclerotherapy is a non-invasive procedure commonly used to treat superficial venous disease, vascular malformations and other ectatic vascular lesions. While extremely rare, sclerotherapy may be complicated by serious adverse events. OBJECTIVES To categorise contraindications to sclerotherapy based on the available scientific evidence. METHODS An international, multi-disciplinary panel of phlebologists reviewed the available scientific evidence and developed consensus where evidence was lacking or limited. RESULTS Absolute Contraindications to sclerotherapy where the risk of harm would outweigh any benefits include known hypersensitivity to sclerosing agents; acute venous thromboembolism (VTE); severe neurological or cardiac adverse events complicating a previous sclerotherapy treatment; severe acute systemic illness or infection; and critical limb ischaemia. Relative Contraindications to sclerotherapy where the potential benefits of the proposed treatment would outweigh the risk of harm or the risks may be mitigated by other measures include pregnancy, postpartum and breastfeeding; hypercoagulable states with risk of VTE; risk of neurological adverse events; risk of cardiac adverse events and poorly controlled chronic systemic illness. Conditions and circumstances where Warnings and Precautions should be considered before proceeding with sclerotherapy include risk of cutaneous necrosis or cosmetic complications such as pigmentation and telangiectatic matting; intake of medications such as the oral contraceptive and other exogenous oestrogens, disulfiram and minocycline; and psychosocial factors and psychiatric comorbidities that may increase the risk of adverse events or compromise optimal treatment outcomes. CONCLUSIONS Sclerotherapy can achieve safe clinical outcomes provided that (1) patient-related risk factors and in particular all material risks are (1a) adequately identified and the risk benefit ratio is clearly and openly discussed with treatment candidates within a reasonable timeframe prior to the actual procedure; (1b) when an individual is not a suitable candidate for the proposed intervention, conservative treatment options including the option of 'no intervention as a treatment option' are discussed; (1c) complex cases are referred for treatment in controlled and standardised settings and by practitioners with more expertise in the field; (1d) only suitable individuals with no absolute contraindications or those with relative contraindications where the benefits outweigh the risks are offered intervention; (1e) if proceeding with intervention, appropriate prophylactic measures and other risk-mitigating strategies are adopted and appropriate follow-up is organised; and (2) procedure-related risk factors are minimised by ensuring the treating physicians (2a) have adequate training in general phlebology with additional training in duplex ultrasound, procedural phlebology and in particular sclerotherapy; (2b) maintain their knowledge and competency over time and (2c) review and optimise their treatment strategies and techniques on a regular basis to keep up with the ongoing progress in medical technology and contemporary scientific evidence.

Abstract
The use of agitated saline contrast (ASC) during echocardiographic examinations is a well-established practice, most commonly performed to identify atrial septal abnormalities in the context of stroke. In the intensive care unit, this technique may be employed to identify anatomic right-to-left shunts (either intracardiac or transpulmonary) that may be contributing to hypoxemic respiratory failure. This narrative review will describe the technique of ASC injection, summarize clinical scenarios where it may be useful, and review the strengths and limitations of the tool.

Abstract
The right-to-left shunt (RTLS) through a latent patent foramen ovale (PFO) is a rare complication of right ventricle myocardial infarction (MI). Though a rare complication, the development of refractory hypoxemia after right ventricular MI should always alert clinicians to consider the possibility of shunting across PFO. Right-sided Impella (Impella RP) can be considered in such patients, which helps to decrease the elevated right heart pressure reducing the shunt, thereby providing a bridge to recovery.

Abstract
We present a case of a woman with past medical history notable for mild COVID-19 infection who presented with dyspnea on exertion, then developed progressively worsening exertional desaturations and was found to have a patent foramen ovale (PFO). Extensive cardiopulmonary testing revealed no clear alternate etiology for her symptoms. After much discussion, she underwent successful closure of the PFO with complete resolution of her symptoms and significantly improved exertional desaturation.

Abstract
OBJECTIVES A significant proportion of the population has a patent foramen ovale (PFO). The intracardiac pressure during cardiopulmonary resuscitation (CPR) may differ from that of normal circulation, which may result in a right-to-left shunt in the presence of a PFO. In this study, transesophageal echocardiography (TEE) was conducted to evaluate whether CPR carried out in patients after cardiac arrest causes right-to-left shunt. DESIGN A retrospective observational study. SETTING One academic medical center from January 2017 to April 2020. PATIENTS Patients older than 20 years who suffered from nontraumatic out-of-hospital cardiac arrest (OHCA) and underwent intra-arrest TEE. MEASUREMENT AND MAIN RESULTS Patients who had microbubbles resulting from fluid injection in the right atrium, as indicated on TEE imaging, were included in the analysis. The presence of right-to-left shunt was defined as the appearance of microbubbles in the systemic circulation, including the left atrium, left ventricle, or aorta. A total of 97 patients were included in the final analysis. A right-to-left shunt was observed in 21 patients (21.6%), and no shunt was found in 76 patients (78.4%). The degree of the right-to-left shunt, determined by the number of microbubbles, was mild in 11 patients (52.4%), moderate in eight (38.0%), and severe in two (9.6%). Multivariate analysis showed that no factors were associated with the presence of right-to-left shunt during CPR. CONCLUSIONS Right-to-left shunts can be appreciated during CPR in patients who experience OHCA. Further studies are needed to verify its clinical significance.

Kim M, Park SY, Hong JM. Simultaneous monitoring of the middle cerebral and basilar arteries to detect right-to-left shunts using transcranial Doppler by agitated saline administration. Sci Rep 2022; 12:6658.

Abstract
Transcranial Doppler (TCD) is an easy, non-invasive, and real-time monitoring device for detecting right-to-left shunts (RLS). Nonetheless, it has limited benefits in patients with poor temporal windows. Therefore, we aimed to investigate whether the basilar artery (BA) window was as effective as the middle cerebral artery (MCA) in detecting RLS during TCD monitoring. Overall, we enrolled 344 patients with stroke, transient ischemic attack, headache, or dizziness. MCA and BA were monitored using a modified headset. To investigate the feasibility of the suboccipital window in detecting RLS, we instituted an evaluation tool with three tiers to evaluate microembolic signals (MESs) during TCD monitoring. Tier 1: TCD monitoring of the MCA (bilaterally) in the resting state, tier 2: TCD monitoring of the MCA (bilaterally) while performing the Valsalva maneuver, and tier 3: TCD monitoring of the index MCA and BA while performing the Valsalva maneuver. In tiers 2 and 3, a high agreement rate of 0.808 and 0.809 (p < 0.001), respectively, on the weighted kappa index, and a high intra-class correlation coefficient of 0.982 and 0.986 (p < 0.001), respectively, were observed on detecting MESs. Our data suggests that the BA window is as effective as the MCA window for detecting RLS on TCD.

Abstract
Cardioaortic embolism to the brain accounts for approximately 15-30% of ischaemic strokes and is often referred to as 'cardioembolic stroke'. One-quarter of patients have more than one cardiac source of embolism and 15% have significant cerebrovascular atherosclerosis. After a careful work-up, up to 30% of ischaemic strokes remain 'cryptogenic', recently redefined as 'embolic strokes of undetermined source'. The diagnosis of cardioembolic stroke remains difficult because a potential cardiac source of embolism does not establish the stroke mechanism. The role of cardiac imaging-transthoracic echocardiography (TTE), transoesophageal echocardiography (TOE), cardiac computed tomography (CT), and magnetic resonance imaging (MRI)-in the diagnosis of potential cardiac sources of embolism, and for therapeutic guidance, is reviewed in these recommendations. Contrast TTE/TOE is highly accurate for detecting left atrial appendage thrombosis in patients with atrial fibrillation, valvular and prosthesis vegetations and thrombosis, aortic arch atheroma, patent foramen ovale, atrial septal defect, and intracardiac tumours. Both CT and MRI are highly accurate for detecting cavity thrombosis, intracardiac tumours, and valvular prosthesis thrombosis. Thus, CT and cardiac magnetic resonance should be considered in addition to TTE and TOE in the detection of a cardiac source of embolism. We propose a diagnostic algorithm where vascular imaging and contrast TTE/TOE are considered the first-line tool in the search for a cardiac source of embolism. CT and MRI are considered as alternative and complementary tools, and their indications are described on a case-by-case approach.

Abstract
: Echocardiography plays an important role both in the diagnosis and the treatment/prevention of embolic stroke of undetermined source and should be performed as soon as possible for preventing ischemic stroke recurrencies, which occur more frequently during the first week after the first ischemic event. Early identification of the cause of a transient ischemic attack or stroke is indeed a primary goal for the neurologist in the Stroke Unit and requires specific diagnostic strategies. Echocardiography, together with other diagnostic tools such as carotid and transcranial ultrasounds, provides this information promptly. In particular, echocardiography might be able to detect the main sources of the embolic stroke, such as atrial fibrillation, ventricular akinesia, aortic atheroma plaques and/or cardiac shunts. The present review discusses the importance and the practical role of echocardiography as a crucial diagnostic tool for detecting the main source of emboli in the setting of the acute stroke.

Abstract
INTRODUCTION The presence of a persistent (patent) foramen ovale (PFO) increases the risk of decompression sickness (DCS) whilst diving with pressurised air. After the diagnosis of a PFO, divers will be offered a number of options for risk mitigation. The aim of this study was to review the management choices and modifications to diving practices following PFO diagnosis in the era preceding the 2015 joint position statement (JPS) on PFO and diving. METHODS A retrospective study was conducted of divers sourced from both the Alfred Hospital, Melbourne and the Divers Alert Network Asia-Pacific during the period 2005-2015. Divers were contacted via a combination of phone, text, mail and email. Data collected included: diving habits (years, style and depths); DCS symptoms, signs and treatment; return to diving and modifications of dive practices; history of migraine and echocardiography (ECHO) pre- and post-intervention; ECHO technique(s) used, and success or failure of PFO closure (PFOC). Analyses were performed to compare the incidence of DCS pre- and post-PFO diagnosis. RESULTS Seventy-three divers were interviewed. Sixty-eight of these returned to diving following the diagnosis of PFO. Thirty-eight underwent PFOC and chose to adopt conservative diving practices (CDPs); 15 chose PFOC with no modification to practices; 15 adopted CDPs alone; and five have discontinued diving. The incidence of DCS decreased significantly following PFOC and/or adoption of conservative diving practices. Of interest, migraine with aura resolved in almost all those who underwent PFOC. CONCLUSIONS Many divers had already adopted practices consistent with the 2015 JPS permitting the resumption of scuba diving with a lowering of the incidence of DCS to that of the general diving population. These results support the recommendations of the JPS.

Abstract
Right-to-left pulmonary and cardiac shunts (RLS) are important causes of refractory hypoxia in the critically-ill perioperative patient. Using a point-of-care ultrasound (POCUS) agitated saline bubble study for an early diagnosis allows patients with clinically significant RLSs to receive expedited therapy. This narrative review discusses the principles of agitated saline ultrasonography as well as the role of POCUS in detecting the most common RLS types seen in the intensive care unit, including patent foramen ovale, atrial septal defects, and pulmonary arterio-venous malformations. An illustrated discussion of the procedure, as well as shunt-enhancing maneuvers (Valsalva or lung recruitment maneuver with subsequent rapid release) is provided. With the wide dissemination of bedside ultrasound within the perioperative and critical care arena, POCUS practitioners should be knowledgeable of the potential pitfalls leading to both false-positive and false-negative studies. False-positive studies may be due to congenital abnormalities, mischaracterization of intrapulmonary shunts as intracardiac shunts (and vice versa), or evidence of the Valsalva effect. False negatives are typically due to respiratory-phasic variation, performing an inadequate shunt-enhancing maneuver, inadequate injection of agitated saline, or pathophysiologic states of elevated left atrial pressure. Finally, alternative POCUS methods for determining presence of an RLS in patients with poor echocardiographic windows are discussed, with a focus on pulsed-wave Doppler interrogation of arterial signals.

Abstract
AIMS Pre-operatively diagnosed patent foramen ovale (PFO) is associated with an increased risk of ischaemic stroke within 30 days after surgery. This study aimed to assess the PFO-attributable ischaemic stroke risk beyond the perioperative period. METHODS AND RESULTS This observational study of adult patients without history of stroke undergoing non-cardiac surgery with general anaesthesia examined the association of PFO with ischaemic stroke 1 and 2 years after surgery using multivariable logistic regression. Of the 144 563 patients included, a total of 1642 (1.1%) and 2376 (1.6%) ischaemic strokes occurred within 1 and 2 years after surgery, 54 (4.7%) and 76 (6.6%) among patients with PFO, and 1588 (1.1%) and 2300 (1.6%) among patients without PFO, respectively. The odds of ischaemic stroke within 1 and 2 years after surgery were increased in patients with PFO: adjusted odds ratio (aOR) 2.01, 95% confidence interval (CI) 1.51-2.69; P < 0.001 and aOR 2.10, 95% CI 1.64-2.68; P < 0.001, respectively. Among patients who underwent contrast transoesophageal echocardiography, the frequency of PFO was 27%, and the increased stroke risk in patients with PFO was robust (aOR 3.80, 95% CI 1.76-8.23; P = 0.001 for year 1). The PFO-attributable risk was mitigated by post-operative prescription of combination antithrombotic therapy (odds ratio 0.41, 95% CI 0.22-0.75; P for interaction = 0.004). CONCLUSION Patients with PFO are vulnerable to ischaemic stroke for an extended period of time after surgery. Physicians should consider implementing PFO screening protocols in patients scheduled for major non-cardiac surgery.

Abstract
Pulmonary embolism can be fatal, especially in high-risk patients who have contraindications to systemic thrombolysis or surgical embolectomy. For this population, interventionalists can provide catheter-directed therapies, including catheter-directed thrombolysis and thrombectomy, using a wide array of devices. Endovascular treatment of pulmonary embolism shows great promise through fractionated thrombolytic drug delivery, fragmentation, and aspiration mechanisms with thrombectomy devices. Although successful outcomes have been reported after using these treatments, evidence is especially limited in patients with both a patent foramen ovale (PFO) and acute pulmonary embolism. In patients with PFO, it is important to consider whether catheter-directed therapy is appropriate or whether surgical embolectomy should instead be performed. An increased risk of paradoxical embolus in these patients supports the use of diagnostic echocardiography with possible surgical closure of PFO after one episode of pulmonary embolism. Percutaneous PFO closure, which can be performed at the time of catheter-based therapy, theoretically reduces risk of future paradoxical embolization, although more data are needed before making a recommendation for this specific group of patients.

Abstract
Venous thromboembolism and ischemic stroke are major complications following total knee arthroplasty (TKA) and potentially are associated with a patent foramen ovale (PFO). Although this association has been shown in other surgical disciplines, it has not been demonstrated in patients undergoing TKA. This study was undertaken to determine whether patients with a PFO would have a significantly increased risk of cerebrovascular accident (CVA) following TKA. The Humana national database was used to identify TKA patients who were stratified by the presence of a PFO from 2007 to 2016. Ninety-day follow-up was used for the primary outcome of CVA. Potential confounding comorbidities also were investigated, including age, sex, anticoagulation, insurance type, arrhythmia, valvular disease, peripheral vascular disease, chronic kidney disease, and diabetes mellitus. Of 153,245 TKAs, a total of 2272 patients had strokes; 479 of these patients had a PFO. On multivariable analysis, PFO remained an independent predictor of CVA postoperatively (odds ratio, 3.824; 95% confidence interval, 2.614-5.406; P<.0001). Other significant comorbidities associated with CVA included arrhythmia, chronic kidney disease, diabetes mellitus, peripheral vascular disease, and coronary valve disease. Importantly, low-molecular weight heparin or factor Xa inhibitor administration postoperatively had a negative correlation with stroke (odds ratio, 0.762; 95% confidence interval, 0.663-0.871; P=.0001 and odds ratio, 0.749; 95% confidence interval, 0.628-0.885; P=.0009, respectively). The findings of the multivariable analysis indicate PFO is associated with early postoperative CVA within 90 days following TKA. If known preoperatively, appropriate referral should be made to a cardiologist for PFO management and anticoagulation to reduce the overall risk of stroke. [Orthopedics. 2020;43(3):e151-e158.].

Abstract
The purpose of the study was to evaluate the impact of transesophageal echocardiography (TEE) – based protocol for management of adults in the sitting position during elective neurosurgical interventions on the incidence of clinically significant venous air embolism (VAE). Material and Methods ― The study involved 155 adult neurosurgery patients (70 in prospective group and 85 in retrospective group). Surgery in both groups was done in the sitting position. In the prospective group TEE-based protocol was used. Retrospective group served as control. The primary endpoint was considered to be a decrease in the frequency of clinically significant VAE in the prospective group in comparison with the retrospective one. In the prospective group, VAE with Tuebingen grade 3-5 was considered clinically significant. The PFO incidence and severity and the effect of the number of episodes of VAE per case on its maximum severity during surgery were also analyzed. Any complication in the postoperative period believed to be associated with the position of the patient on the table during the surgery was recorded. Results ― The incidence of the clinically significant VAE in the retrospective group was 23.5% (95% CI 15-34) and was 16.4% higher than the frequency in the prospective group (chi-square=7.6197, df=1, p=0.005). 50% (95% CI 38-62) of patients in prospective group developed VAE during surgery. In 16 cases, the number of episodes was more than one. The number of episodes of VAE in the observation was reliably associated with the maximum severity of VAE during the observation (Z=4.11; p<0.001). A moderate strength relationship was determined between them (SomersDelta=0.43; 95% CI 0.17-0.7). Not a single case of paradoxical air embolism was detected in a series of observations. None of the patients has got a neurological deficit or cardiopulmonary complications associated with the position on the surgical table in the postoperative period. Pneumocephalus was found in 100% of cases on head computed tomography, which, however, did not need surgical treatment. PFO in the prospective group was detected in 62% (95% CI 52-73) of patients. In 25% (95% CI 16-35), shunting was significant. A large PFO without Valsalva maneuver was detected in 12.5% (95% CI 6-21) of cases. Conclusion ― The use of the TEE-based protocol for the management of adult patients in a sitting position during elective neurosurgical interventions can reduce the incidence of clinically significant VAE.

Abstract
Introduction: The treatment options for prevention of recurrent of cryptogenic stroke in patients with patent foramen ovale (PFO) have been intensely debated in the recent decades. The suggested options were percutaneous closure of PFO versus medical therapy. However, up to these date there is a controversy regarding the indication of percutaneous closure. Multiple meta-analysis and recent randomized control trials showed the benefit of PFO closure when compared with medical therapy alone. Areas covered: The article reviews the prevalence, physiology, diagnosis and treatment options of PFO after cryptogenic stroke. Furthermore, it will discuss the results of randomized control trials that compared the PFO closure to medical therapy. Expert opinion: The association between PFO and unexplained cryptogenic stroke has been well established in the multiple studies. The diagnosis and management of PFO might be challenging in some cases. Although multiple studies showed that PFO closure is associated with lower rates of recurrent stroke in patients presenting with cryptogenic stroke, the indication and patient selection for this intervention are not well established yet in the guidelines.

Abstract
A patent foramen ovale (PFO) has been shown to be highly prevalent in patients
diagnosed with strokes of unknown cause, which are also called cryptogenic
strokes (CSs). It has been a long-running controversy as to whether a PFO should
be closed or not to prevent recurrent strokes in patients diagnosed with CS. A
paradoxical embolism that is produced through a PFO is hypothesized to be a
leading cause of CS, especially in younger patients with low risk factors for
stroke. It remains controversial as to which anticoagulation therapy, defined as
antithrombin or antiplatelet therapy, is better for patients with CS and a PFO.
In addition, surgical and transcutaneous closure of a PFO has been proposed for
the secondary prevention of stroke in patients with CS with PFO. Several
randomized controlled trials have been conducted in recent years to test whether
a PFO closure gives a significant benefit in the management of CS. Three earlier
randomized controlled trials failed to show a statistically significant benefit
for a PFO closure; thus, many investigators believed that a PFO was an
incidental bystander in patients with CS. However, meta-analyses and more recent
specific trials have eliminated several confounding factors and possible biases
and have also emphasized the use of a shunt closure over medical therapy in
patients with CS. Therefore, these latest studies (the CLOSE and REDUCE trials)
can possibly change the treatment paradigm in the near future.

Abstract
BACKGROUND Therapeutic uncertainty is inherent in decisions in patients with patent foramen ovale (PFO) and cryptogenic stroke. We aimed to determine clinical implications of PFO identification in transesophageal echocardiography (TEE) after a cryptogenic ischemic stroke. METHODS Consecutive TEE done between 2011 and 2015 in patients with previous cryptogenic stroke was evaluated. Clinical implications of PFO identification (closure and/or medical therapy) were retrieved from the medical records and discharge summaries. Adverse events related to therapy, stroke recurrence and death were analyzed during follow-up. RESULTS Three-hundred one patients (mean age 59 ± 11 years; 61% male) underwent a TEE, of which 77 (26%) patients had a diagnosis of PFO. Patients with PFO were younger (56 ± 13 versus 60 ± 14, p = 0.03). Of those with PFO, 23 (30%) underwent percutaneous closure of PFO and these patients had more frequently complex or large PFO (p < 0.001 and p = 0.004, respectively). The remaining 54 (70%) were treated with medical therapy: 30 (39%) with antiplatelet therapy and 24 (31%) with oral anticoagulation. During follow-up (44 ± 17 months), only two patients had another stroke (both referred for PFO closure, while they were waiting for the procedure) and two patients, on whom PFO closure was not performed, died (not for cardiovascular causes). CONCLUSION PFO's (size and complexity) and patients' characteristics influenced clinical decision when PFO was detected on TEE. The risk for recurrent stroke was not increased in patients who did not undergo PFO closure; although two patients waiting for PFO closure had recurrent stroke, demonstrating its importance.

Abstract
Acute pulmonary embolism (APE) is characterized by numerous clinical manifestations which are the result of a complex interplay between different organs; the symptoms are therefore various and part of a complex clinical picture. For this reason, it may not be easy to make an immediate diagnosis. This is a comprehensive review of the literature on all the various clinical pictures in order to help physicians to promptly recognize this clinical condition, remembering that our leading role as cardiologists depends on and is influenced by our knowledge and working methods.

Abstract
A 77-year-old Caucasian woman with recent abdominal surgery was diagnosed with multiple paradoxical systemic emboli in the mesenteric and renal circulation. Diagnosis was made by direct visualisation of a serpentine thrombus traversing both atria through patent foramen ovale (PFO) by transesophageal echocardiogram (TEE). Concomitantly, the patient was found to have deep venous thrombosis and pulmonary embolism. A decision was made to pursue cardiothoracic surgery preceded by inferior vena cava filter placement. She was started on intravenous anticoagulation. Repeat TEE was negative for thrombus and the patient did not present any new clinical signs of embolisation by this time. Consequently, the treatment plan was modified and the patient received oral systemic anticoagulation followed by PFO closure with the use of St. Jude Amplatzer Cribriform septal occluder device. During the outpatient follow-up the patient was asymptomatic and there was no significant flow through the device on transthoracic echocardiogram.

Abstract
INTRODUCTION Patent foramen ovale (PFO) is a common anatomical variant in the adult circulation. It is a channel allowing communication between the left and right atria and is a remnant of the foetal circulation. In approximately 25% of the population, this channel persists into adulthood. PFO has been proposed as a potential pathophysiological mechanism for cryptogenic stroke. Areas covered: This review will examine the contemporary evidence for both the association between cryptogenic stroke and PFO and the management of this condition. The authors hope to provide a comprehensive overview of the current evidence and best practice in relation to PFO closure. In addition, the authors will propose some potential avenues for future research in this controversial area and try to predict how PFOs in cryptogenic stroke will be managed in the near future. Expert commentary: In carefully selected patients with cryptogenic stroke, PFO closure represents an evidence based treatment option for the prevention of further ischemic neurological events. A multidisciplinary approach is necessary to ensure appropriate patient selection for the procedure. This should include a vascular neurologist/stroke physician and an interventional cardiologist with an interest in PFO closure.

Abstract
Dyspnea and hypoxemia are common postoperative problems after pneumonectomy. One of the rarer causes of respiratory distress after right pneumonectomy is the development of a significant right-to-left shunt across a patent foramen ovale (PFO), which can evolve at a variable interval of time after the operation. We report here our experience with a patient who underwent right pneumonectomy, followed by several complications, and who presented severe dyspnea 7 months later, after the closure of a right thoracostomy. This report outlines the management of this challenging clinical condition; transesophageal echocardiography (TOE) provided a clear diagnosis and guided an effective percutaneous treatment.

Abstract
This report will review the role of echocardiography in the diagnosis of cardiac sources of embolism. Embolism of cardiac origin accounts for around 15%–30% of ischemic strokes. The diagnosis of a cardioembolic source of stroke is frequently uncertain and relies on the identification of a potential cardiac source of embolism in the absence of significant autochthonous cerebrovascular occlusive disease. Transthoracic and/or transesophageal echocardiography serves as a cornerstone in the evaluation, diagnosis, and management of these patients. This article reviews potential cardiac sources of embolism and discusses the role of echocardiography in clinical practice. Recommendations for the use of echocardiography in the diagnosis of cardiac sources of embolism are given including major and minor conditions associated with the risk of embolism.

Abstract
In-hospital mortality rate of an embolus in transit is as high as 44.7%. In some cases, a paradoxical embolus can get stuck in a patent foramen ovale. Because of the high mortality rate, this condition should be considered as an emergency case. Echocardiography has been established as the gold standard method for the diagnosis. A negative echocardiography, however, does not rule out an embolus in transit. To rule out pulmonary embolisms, a computed tomography scan of the chest should also be performed. A cardiothoracic surgeon should be consulted immediately upon diagnosis of an embolus in transit. There is no medical consensus for the treatment of the above mentioned condition, however, surgical treatment appears to be the best approach in patients who are surgical candidates.

Abstract
PURPOSE To explore significance, management, and outcomes of central venous catheter (CVC) tip-associated thrombi incidentally detected on echocardiography. MATERIALS AND METHODS Echocardiogram data from all patients with CVCs from October 2009 to June 2011 were reviewed (N = 170). Patients with CVC tip-associated thrombi were selected (n = 49). Echocardiograms were reviewed for ejection fraction, presence of patent foramen ovale (PFO), presence of other intracardiac shunts, and mean thrombus size. Management decisions, thrombus extension, pulmonary embolism, paradoxical emboli, and stroke within 3 months were recorded. RESULTS Mean thrombus size was 2.1 cm (range, 0.5-5.7 cm). Of patients with thrombi, 11 (22%) were already on anticoagulation, and there was no change in management. Anticoagulation was started without complications in 17 (35%) patients, the catheter was removed in 4 (8%) patients, and no new treatment was initiated in 17 (35%) patients. Of these 17 patients, 16 (94%) developed no complications. One (6%) patient with a PFO and right-to-left shunt experienced a stroke before PFO closure. After surgical closure of the PFO, the same patient developed catheter tip-associated thrombus without complication. There were no pulmonary emboli, strokes, or other detected embolic phenomena. CONCLUSIONS In this sample with CVC tip-associated thrombi but without PFO or other intracardiac shunts, no embolic or other complications were detected, regardless of anticoagulation status. These data suggest a benign course for such thrombi and that anticoagulation, catheter removal, thrombectomy, and thrombolysis may be unnecessary when catheter tip-associated thrombi are incidentally detected on echocardiography.

Abstract
BACKGROUND The purpose of this study was to evaluate the reliability, effectiveness, and safety of modified right heart contrast transthoracic echocardiography (cTTE) in comparison with the traditional method. MATERIAL/METHODS We performed a modified right heart cTTE using saline mixed with a small sample of patient's own blood. Samples were agitated with varying intensity. This study protocol involved microscopic analysis and patient evaluation. 1. Microscopic analysis: After two contrast samples had been agitated 10 or 20 times, they underwent a comparison of bubble size, bubble number, and red blood cell morphology. 2. Patient analysis: 40 patients with suspected RLS (right- to-left shunt) were enrolled. All patients underwent right heart contrast echocardiography. Oxygen saturation, transit time and duration, presence of RLS, change in indirect bilirubin and urobilinogen concentrations were compared afterward. RESULTS Modified method generated more bubbles (P<0.05), but the differences in bubble size were not significant (P>0.05). Twenty-four patients were diagnosed with RLS (60%) using the modified method compared to 16 patients (40%) with the traditional method. The transit time of ASb20 group was the shortest (P<0.05). However, the duration time in this group was much longer (P<0.05). Also, in semi-quantitative analysis mean rank of RLS was higher after injecting the modified contrast agent agitated 20 times (P<0.05). CONCLUSIONS Modified right heart contrast echocardiography is a reliable, effective and safe method of detecting cardiovascular RLS.

Abstract
BACKGROUND Over the last two decades the interest on patent foramen ovale (PFO) as a cause of cardioembolism in cryptogenic stroke has tremendously increased, thanks to the availability of better techniques to diagnose cardiac right-to-left shunt by ultrasounds and of percutaneous means of PFO treatment with interventional techniques. Many studies have been published that have attempted to define diagnostic methodology, prognosis, and optimal treatment (pharmacological or percutaneous closure) of PFO patients with cryptogenic stroke. Unfortunately, even today, definitive evidence is still lacking, and clinical management is not consistent among cardiologists. AIMS This review aims to evaluate the role of PFO in cryptogenic stroke, the diagnostic accuracy of transcranial Doppler, contrast transthoracic and transesophageal echocardiography in the diagnosis of left-fright shunt and PFO; and discuss the indications to medical treatment and percutaneous closure of PFO. METHODS All studies published in the literature on PFO and cryptogenic stroke are considered and discussed. RESULTS We define an appropriate diagnostic and clinical management of PFO patients with cryptogenic stroke. CONCLUSION After many years of interest on PFO and many concluded studies, there are still no definitive data. However, we are on good track for an appropriate management of PFO patients and cryptogenic stroke.

Abstract
Background Atrial fibrillation (AF) may be the cause or sequela of left atrial abnormalities and variants. Purpose To determine the prevalence of left atrial (LA) abnormalities in AF patients compared to normal sinus rhythm (NSR) patients. Material and Methods We retrospectively reviewed 281 cardiac CT examinations from 2010 to 2012, excluding patients with prior pulmonary vein ablation, known coronary artery disease, prior coronary stent placement, or coronary artery bypass grafts. The first group consisted of 159 AF patients undergoing cardiac CT prior to pulmonary vein ablation and the second group consisted of 122 NSR patients evaluated with coronary CT angiography. Demographic data were collected. LA abnormalities were analyzed. Left atrial diameter was measured on an axial view. Results A total of 281 patients were included. The male gender has significantly higher prevalence of AF than female gender, P value <0.001. Patients with AF were significantly older (mean age, 57.4 years; standard deviation [SD], 11.8 years) than NSR patients (mean age, 53.4 years; SD, 13.6 years), P value, 0.01. The left atrial diameter was greater in the AF patients (mean diameter, 4.3 cm; SD, 0.82 cm) versus the NSR patients (3.4 cm; SD, 0.58 cm), P value, <0.0001. LA diverticulum was the most prevalent variant, occurring in 28.4% of the entire patient population followed by LA pouch, occurring in 24%. There was no significant between group differences in the prevalence of these or the remainder of the LA variants. Conclusion AF patients differed significantly from NSR patients in LA size, gender, and mean age. There was no statistical significance between the two groups with regard to the LA morphologic abnormalities other than size.

Abstract
In rare cases, thrombus in transit can be entrapped in a patent foramen ovale (PFO). A patient with this condition is at high risk of embolic stroke and death. Early diagnosis and treatment is essential to help prevent stroke and death in these cases. There is no universal management guideline for this rare condition. The decision between medical versus surgical treatment should be made individually for each patient. We present a case of thrombus in transit entrapped in a PFO that was treated medically by lifelong anticoagulation.

Abstract
Patent foramen ovale (PFO) is associated with an increased risk of decompression sickness (DCS) in divers that results from a paradoxical embolization of nitrogen bubbles. The number of scuba divers worldwide is estimated in the millions, and the prevalence of PFO is 25%-30% in adults. It is interesting that despite these numbers, many important issues regarding optimal screening, risk stratification, and management strategy still remain to be resolved. Recently published data suggest the possible effectiveness of both PFO closure and conservative diving measures in preventing arterial gas embolization. This review aims to introduce the basic principles of physiology and the pathophysiology of bubble formation and DCS, summarize the current literature on PFO and diving, and review the possibilities of diagnostic workup and management.

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
Patent foramen ovale (PFO) is highly prevalent and associated with more than 150,000 strokes per year. Traditionally, it is thought that PFOs facilitate strokes by allowing venous clots to travel directly to the brain. However, only a small portion of PFO stroke patients have a known tendency to form blood clots, and the optimal treatment for this multiorgan disease is unclear. Therefore, mapping the changes in systemic circulation of PFO-related stroke is crucial in understanding the pathophysiology to individualize the best clinical treatment for each patient. We initiated a study using a novel quantitative, 2-pass discovery workflow using high-resolution liquid chromatography-mass spectrometry/mass spectrometry coupled with label-free analysis to track protein expression in PFO patients before and after endovascular closure of the PFO. Using this approach, we were able to demonstrate quantitative differences in protein expression between both PFO-related and non-PFO-related ischemic stroke groups as well as before and after PFO closure. As an initial step in understanding the molecular landscape of PFO-related physiology, our methods have yielded biologically relevant information on the synergistic and functional redundancy of various cell-signaling molecules with respect to PFO circulatory physiology. The resulting protein expression patterns were related to canonical pathways including prothrombin activation, atherosclerosis signaling, acute-phase response, LXR/RXR activation, and coagulation system. In particular, after PFO closure, numerous proteins demonstrated reduced expression in stroke-related canonical pathways such as acute inflammatory response and coagulation signaling. These findings demonstrate the feasibility and robustness of using a proteomic approach for biomarker discovery to help gauge therapeutic efficacy in stroke.

Abstract
Patent foramen ovale (PFO), a common congenital cardiac abnormality, is a connection between the right and left atria in the heart. As a "back door to the brain", PFO can serve as a conduit for paradoxical embolism, allowing venous thrombi to enter the arterial circulation, avoiding filtration by the lungs, and causing ischemic stroke. PFO-related strokes affect more than 150,000 people per year in the US, and PFO is present in up to 60% of migraine patients with aura, and in one out of four normal individuals. So, in such a highly prevalent condition, what are the best treatment and prevention strategies? Emerging studies show PFO-related neurovascular disease to be a multi-organ condition with varying individual risk factors that may require individualized therapeutic approaches - opening the field for new pharmacologic and therapeutic targets. The anatomy of PFO suggests that, in addition to thrombi, it can also allow harmful circulatory factors to travel directly from the venous to the arterial circulation, a concept important in finding novel therapeutic targets for PFO-related neurovascular injury. Here, we: 1) review emerging data on PFO-related injuries and clinical trials; 2) discuss potential mechanisms of PFO-related neurovascular disease in the context of multi-organ interaction and heart-brain signaling; and 3) discuss novel therapeutic targets and research frontiers. Clinical studies and molecular mapping of the circulatory landscape of this multi-organ disease will both be necessary in order to better individualize clinical treatment for a condition affecting more than a quarter of the world's population.

Abstract
Neurovascular disease often involves multi-organ system injury. For example, patent foramen ovale (PFO) related ischemic strokes involve not just the brain, but also the heart, the lung, and the peripheral vascular circulation. For higher-risk but high-reward systemic therapy (e.g., thrombolytics, therapeutic hypothermia (TH), PFO closure) to be implemented safely, very careful patient selection and close monitoring of disease progression and therapeutic efficacy are imperative. For example, more than a decade after the approval of therapeutic hypothermic and intravenous thrombolysis treatments, they both remain extremely under-utilized, in part due to lack of clinical tools for patient selection or to follow therapeutic efficacy. Therefore, in understanding the complexity of the global effects of clinical neurovascular diseases and their therapies, a systemic approach may offer a unique perspective and provide tools with clinical utility. Clinical proteomic approaches may be promising to monitor systemic changes in complex multi-organ diseases - especially where the disease process can be 'sampled' in clinically accessible fluids such as blood, urine, and CSF. Here, we describe a 'pharmaco-proteomic' approach to three major challenges in translational neurovascular research directly at bedside - in order to better stratify risk, widen therapeutic windows, and explore novel targets to be validated at the bench - (i) thrombolytic treatment for ischemic stroke, (ii) therapeutic hypothermia for post-cardiac arrest syndrome, and (iii) treatment for PFO related paradoxical embolic stroke. In the future, this clinical proteomics approach may help to improve patient selection, ensure more precise clinical phenotyping for clinical trials, and individualize patient treatment.

Abstract
The Platypnea-Orthodeoxia syndrome is characterised by dyspnoea and deoxygenation accompanying a change from the recumbent to the upright position. An 81-year-old woman had an elective paraesophageal hernia repair. She developed dyspnoea and hypoxemia post-operatively that was worse when upright. An agitated saline echocardiogram revealed a right-to-left shunt through a patent foramen ovale that increased when the patient was upright. Over 3 weeks the patients' shunt, dyspnoea and hypoxemia improved and she was discharged home.

Abstract
BACKGROUND Right-to-left shunting via a patent foramen ovale (PFO) has a recognized association with embolic events in younger patients. The use of agitated saline contrast injection (ASCi) for detecting atrial shunting is well documented, but the optimal technique is not well described. The purpose of this study was to assess the efficacy and safety of transthoracic echocardiographic (TTE) ASCi for the assessment of right-to-left atrial communication in a large cohort of patients. METHODS A retrospective review was undertaken of 1,162 consecutive patients who underwent TTE ASCi, of whom 195 had also undergone clinically indicated transesophageal echocardiography. ASCi shunt results were compared with color flow imaging, and the role of provocative maneuvers (PM) was assessed. RESULTS Four hundred three TTE studies (35%) had paradoxical shunting seen during ASCi. Of these, 48% were positive with PM only. There was strong agreement between TTE ASCi and reported transesophageal echocardiographic findings (99% sensitivity, 85% specificity), with six false-positive and two false-negative results. In hindsight, the latter were likely due to suboptimal right atrial opacification and the former to transpulmonary shunting. TTE color flow imaging was found to be insensitive (22%) for the detection of a PFO compared with TTE ASCi. CONCLUSIONS TTE color flow imaging is too insensitive for PFO screening. TTE ASCi, however, is simple and highly accurate for the detection of right-to-left atrial communication, on the proviso that a dedicated protocol, including correctly implemented PM, is followed. It is recommended that TTE ASCi with PM be considered the primary diagnostic tool for the detection of PFO in clinical practice.

The echocardiographic diagnosis of cardiac thrombi, vegetations and tumors as well as the identification of predisposing conditions such as patent foramen ovale, aortic atherosclerosis and other minor causes (e.g., mitral valve prolapse, mitral and aortic valve calcification) have crucial clinical relevance, affecting the choice of surgery and/or of pharmaceutical therapy in the setting of patients presenting embolism. The echocardiographic assessment helps not only for the retrospective diagnosis of sources of embolism but also for the prevention of events in asymptomatic patients. Echocardiography can also distinguish normal variants and artifacts from cardiac masses and tumors. Echocardiographic characterization/typology of cardiac sources of embolism is currently below par when compared with cardiac MRI, the current gold standard. Nevertheless, echocardiography remains the 'first-line' imaging tool, because of its low cost and the possibility to add easily available, functional and structural information at the patient's bedside.

Abstract
PURPOSE The aim of this study was to investigate the frequency with which interatrial shunts are found during routine coronary computed tomography (CT) angiography and to describe imaging characterizations of patent foramen ovale (PFO), atrial septal defect (ASD), and atrial septal aneurysm (ASA). MATERIALS AND METHODS A total of 1081 adult patients were evaluated retrospectively for interatrial shunting; 77 were excluded from the study. CT diagnosis of PFO was defined as (1) a channel-like appearance of the interatrial septum (IAS) and (2) a contrast agent jet flow from the left atrium (LA) to the right atrium (RA). ASD was defined as (1) the IAS resembling a membrane with a hole and (2) a contrast jet flow between the two atria. ASA was identified by detecting a minimum 10-mm protrusion of the LA beyond the IAS into the RA. RESULTS Among 1004 patients, 86 patients (8.6%) were diagnosed to have PFO. Another 23 patients (2.3%) had a hole in the IAS and were diagnosed as having ASD: 21 with an ostium secundum-type ASD and 2 with the sinus venosus type. ASA accompanied ASD in three patients. CONCLUSION Electrocardiography-gated CT using the saline-chaser contrast injection technique that is routinely used for coronary arterial imaging can be used to detect interatrial shunts. The technique can also serve as a method for differentiating PFO, ASD, and ASA.
