Abstract
INTRODUCTION The role of transesophageal echocardiography (TEE) in cryptogenic stroke and transient ischemic attack (TIA) with normal transthoracic echocardiography (TTE) remains controversial in the absence of definite guidelines. We aimed to perform a systematic review and meta-analysis to estimate an additional diagnostic yield and clinical impact of TEE in patients with cryptogenic stroke and TIA with normal TTE. METHODS We performed a systematic review of cohort studies on PubMed using the keywords 'cryptogenic stroke', cryptogenic TIA', 'TEE', and 'TTE' with matching MeSH terms. We included studies with patients who had cryptogenic stroke or TIA and had normal TTE findings, where the study intended to obtain TEE on all patients and reported all TEE abnormalities. The studies containing patients with atrial fibrillation were excluded. All studies were evaluated for internal and external validity. Inverse variance random effects models were used to calculate the effect size, the number needed to diagnose, and the 95% confidence interval. RESULTS We included 15 studies with 2054 patients and found LA/LAA/aortic thrombus, valvular vegetation, PFO-ASA, valvular abnormalities, and complex aortic plaques on TEE. Of these, 37.5% (29.7%-45.1%) of patients had additional cardiac findings on TEE. Management of 13.6% (8.1%-19.1%) of patients had changed after TEE evaluation. Based on current guidelines, it should change management in 4.1% (2.1%-6.2%) of patients and could potentially change management in 30.4% (21.9%-38.9%) of patients. Sensitivity analysis was also performed with only class II studies to increase internal validity, which showed additional cardiac findings in 38.4% (28.5%-48.3%), changed management in 20.2% (8.7%-31.8%), should change management in 4.7% (1.5%-7.9%), and could potentially change management in 30.4% (17.8%-43.0%) of patients. CONCLUSIONS The diagnostic yield of TEE to find any additional cardiac findings in patients with cryptogenic stroke or TIA is not only high, but it can also change management for certain cardiac abnormalities. TTE in cryptogenic stroke or TIA may mitigate future risks by tailoring the management of these patients.

[PMID: 34189351 PMCID: PMC8191534 DOI: 10.4103/bc.bc_68_20] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 11/30/2020] [Revised: 02/06/2021] [Accepted: 02/22/2021] [Indexed: 11/21/2022] Open
Abstract
INTRODUCTION: Acute ischemic stroke (AIS) in the young age (≤50 years) is a major cause of disability. The underlying mechanism of AIS in this age group is usually different from elderly. Transthoracic echocardiography (TTE) is used to detect the potential cardiac sources of embolism in AIS patients. Transthoracic echocardiogram (TEE) is superior to detect specific underlying cardio-aortic source of embolism when compared to TTE. We aim to evaluate the diagnostic yield and therapeutic impact of TEE in AIS of young adults. METHODS: We retrospectively reviewed the consecutive patients with AIS in our comprehensive center in a 5-year period from our prospectively collected registry. We selected patients with age ≤50 years who had acute infarcts on brain magnetic resonance imaging or head computed tomography and underwent TEE as part of their diagnostic workup. Demographic details including, age, gender, body mass index, cardiovascular risk factors profile, and TEE findings were collected. RESULTS: Among a total 7,930 patients, 876 (11.04%) were found to be ≤50 years old. Among those, TEE was done in 113 patients (12.8%) in addition to TTE. Those who underwent TEE had a mean age of 40.4 ± 7.9 years, 60 were male (53%), 7 (6.2%) had a history of coronary artery disease, 38 (33%) had a history of diabetes, and 45 (40%) had a history of smoking. TEE showed new abnormal findings in a total of 15 patients (13.2%) that were not reported in their TTEs. Out of these, left atrial appendage thrombus was found in 5, infective endocarditis in 4, atrial septal aneurysms associated with patent foramen ovale (PFO) in 3, and spontaneous mobile echo density in three patients. Overall, new findings from TEE resulted in change in the secondary stroke prevention strategy in 14 patients of those who underwent TEE (12.3%). TEE also confirmed the presence of PFO, which was present on TTE with bubble study in 20 (17.6%) patients. CONCLUSION: TEE may provide additional information in the evaluation of the AIS in young adults, which could lead to change of the secondary stroke prevention strategy.

Detection of Major Cardioembolic Sources in Real-World Patients with Ischemic Stroke or Transient Ischemic Attack of Undetermined Cause. Cerebrovasc Dis Extra 2021; 11:22-28. [PMID: 33524986 PMCID: PMC7989814 DOI: 10.1159/000512743] [Citation(s) in RCA: 1] [Impact Index Per Article: 0.3] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 09/17/2020] [Accepted: 11/01/2020] [Indexed: 11/25/2022] Open
Abstract
Background/Aim Current guidelines recommend transthoracic echocardiography (TTE) and ambulatory rhythm monitoring following ischemic stroke or transient ischemic attack (TIA) of undetermined cause for identifying cardioembolic sources (CES). Due to ongoing controversies about this routine strategy, we evaluated its yield in a real-world setting. Methods In a tertiary medical center, we retrospectively evaluated consecutive patients with ischemic stroke or TIA of undetermined cause, who (after standard work-up) underwent TTE, ambulatory rhythm monitoring, or both. CES were classified as major if probably related to ischemic events and warranting a change of therapy. Results Between January 2014 and December 2017, 674 patients had ischemic stroke or TIA of undetermined cause. Of all 484 patients (71.8%) who underwent TTE, 9 (1.9%) had a major CES. However, 7 of them had already been identified for cardiac evaluation due to new major electrocardiographic abnormalities or cardiac symptoms. Thus, only 2 patients (0.4%) truly benefitted from unselected TTE screening. Ambulatory rhythm monitoring was performed in 411 patients (61.0%) and revealed AF in 10 patients (2.4%). Conclusion Detecting a major CES is essential because appropriate treatment lowers the risk of recurrent stroke. Nonetheless, in this real-world study that aimed at routine use of TTE and ambulatory rhythm monitoring in patients with ischemic stroke or TIA of undetermined cause, the prevalence of major CES was low. Most patients with major CES on TTE already had an indication for referral to a cardiologist, suggesting that major CES might also have been identified with a much more selective use of TTE.

Abstract
Background and Purpose- The purpose of these guidelines is to provide an up-to-date comprehensive set of recommendations in a single document for clinicians caring for adult patients with acute arterial ischemic stroke. The intended audiences are prehospital care providers, physicians, allied health professionals, and hospital administrators. These guidelines supersede the 2013 Acute Ischemic Stroke (AIS) Guidelines and are an update of the 2018 AIS Guidelines. Methods- Members of the writing group were appointed by the American Heart Association (AHA) Stroke Council's Scientific Statements Oversight Committee, representing various areas of medical expertise. Members were not allowed to participate in discussions or to vote on topics relevant to their relations with industry. An update of the 2013 AIS Guidelines was originally published in January 2018. This guideline was approved by the AHA Science Advisory and Coordinating Committee and the AHA Executive Committee. In April 2018, a revision to these guidelines, deleting some recommendations, was published online by the AHA. The writing group was asked review the original document and revise if appropriate. In June 2018, the writing group submitted a document with minor changes and with inclusion of important newly published randomized controlled trials with >100 participants and clinical outcomes at least 90 days after AIS. The document was sent to 14 peer reviewers. The writing group evaluated the peer reviewers' comments and revised when appropriate. The current final document was approved by all members of the writing group except when relationships with industry precluded members from voting and by the governing bodies of the AHA. These guidelines use the American College of Cardiology/AHA 2015 Class of Recommendations and Level of Evidence and the new AHA guidelines format. Results- These guidelines detail prehospital care, urgent and emergency evaluation and treatment with intravenous and intra-arterial therapies, and in-hospital management, including secondary prevention measures that are appropriately instituted within the first 2 weeks. The guidelines support the overarching concept of stroke systems of care in both the prehospital and hospital settings. Conclusions- These guidelines provide general recommendations based on the currently available evidence to guide clinicians caring for adult patients with acute arterial ischemic stroke. In many instances, however, only limited data exist demonstrating the urgent need for continued research on treatment of acute ischemic stroke.
