  • Presumed left atrial myxoma presenting with seizures, massive stroke, and systemic embolization in an adolescent: a case report. [Journal Article]
    Int J Emerg Med. 2026 Sep 09; 19(1).Akbari A, Amiri M, … Salehi FIJ
  • CONCLUSIONS: A cardiac source of embolism, including a left atrial mass highly suggestive of myxoma, should be considered in pediatric patients presenting with acute neurological deficits, particularly when accompanied by systemic embolic phenomena or unexplained cardiopulmonary symptoms. Early echocardiographic evaluation is critical for timely recognition and appropriate clinical decision-making. In the absence of surgical excision and histopathological confirmation, the diagnosis should remain presumptive. Delayed recognition may result in catastrophic neurological and systemic complications and may preclude definitive diagnosis and surgical management.

  • A 40-Year-Old Woman With Exertional Dyspnea and Unexplained Hypoxia. [Case Reports]
    Chest. 2026 Sep; 170(3):e91-e95.Liang YD, Meng WQ, … Xu XMChest
  • A 40-year-old woman presented with a 3-week history of progressive exertional dyspnea. She had previously been active, but her symptoms progressed to the point where she was short of breath with walking. Her oxygen level was 90% at rest and decreased to 70% to 80% after exertion. The patient denied fever, cough, sputum production, edema, syncope, or other clinically remarkable symptoms. No signif…

  • Association between state-level syncope driving policies and motor vehicle crash rates in the United States. [Journal Article]
    Traffic Inj Prev. 2026 Sep 09; :1-8. [Online ahead of print]Dreher L, Mishra N, … Sorajja DTI
  • CONCLUSIONS: Mandatory physician reporting was consistently associated with lower older-driver crash rates across primary and sensitivity analyses. Longer minimum restriction duration showed a supportive but model-dependent association. These findings suggest that an organized reporting and medical-review pathway may be more consequential than restriction duration alone, but the ecological design does not establish causality or individual driving risk.

  • Tilt Table Testing in Paediatric Orthostatic Intolerance: Is 10 Min Long Enough? [Journal Article]
    J Paediatr Child Health. 2026 Sep 09. [Online ahead of print]Choi W, Yun SWJP
  • CONCLUSIONS: In paediatric COI, a 10-min HUTT may be insufficient to detect diagnostically relevant haemodynamic responses. These findings suggest that future studies of paediatric COI may need to consider orthostatic testing protocols with a minimum duration of 20 min to optimise diagnostic yield.

  • Long intramural left coronary artery confined to the left sinus of Valsalva with diastolic deformation: a case report. [Case Reports]
    Eur Heart J Case Rep. 2026 Sep; 10(9):ytag661.Kawabata T, Nabeshima J, … Fujita TEH
  • CONCLUSIONS: This report describes a rare variant of AAOCA characterized by a long intramural course confined to the left sinus of Valsalva without an interarterial course. Despite the absence of a typical malignant course, the patient had symptoms suggestive of myocardial ischaemia. Multimodality imaging played a key role in diagnosis and surgical planning, while IVUS provided complementary structural and dynamic information by demonstrating luminal changes. Surgical unroofing may therefore be considered for symptomatic paediatric patients with a substantial intramural segment even without an interarterial course.

  • Vagal activity related events and glucagon-like peptide-1 receptor agonists. [Journal Article]
    Eur Heart J Cardiovasc Pharmacother. 2026 Sep 08. [Online ahead of print]Al-Ansary L, Kinnberg Nielsen S, … Holt AEH
  • CONCLUSIONS: In nationwide cohorts of patients treated for T2DM or obesity, initiation of GLP-1 RA was not associated with an elevated risk of VAR events. Despite a proposed argumentation of vagal activity, GLP-1 RA use was not associated with an increased risk in real-life users.

  • Clinical Characteristics and Early Outcomes of Acute Pulmonary Embolism Presenting with Syncope. [Journal Article]
    Thromb Haemost. 2026 Sep 07. [Online ahead of print]López-Rubio M, Martínez-Castilla VM, … Demelo-Rodriguez PTH
  • CONCLUSIONS: In acute PE, syncope identifies patients at higher risk of early adverse outcomes. This association was substantially attenuated after accounting for measured acute severity, suggesting that syncope mainly marks a more severe initial presentation rather than carrying prognostic information independent of severity.

  • Improvement of post-COVID-19 vaccination dysautonomia with GLP-1 receptor agonist. [Journal Article]
    Immunopharmacol Immunotoxicol. 2026 Sep 06; :1-6. [Online ahead of print]Blitshteyn S, Schofield JR, … Afrin LBII
  • Vasovagal syncope (VVS) is the most common form of cardiovascular dysautonomia that has multiple etiologies. Post-vaccination dysautonomia, in the form of VVS and postural orthostatic tachycardia syndrome, has been reported in the literature after various vaccines, including COVID-19 mRNA vaccination. Treatment of post-vaccination syndromes has not been explored leaving patients with post-vaccina…

  • Time-Dependent Diagnostic Yield and Therapeutic Impact of Implantable Loop Recorders, Brugada Syndrome as the Exception. [Journal Article]
    J Cardiovasc Electrophysiol. 2026 Sep 06. [Online ahead of print]Cocchiara L, Brescia B, … Rapacciuolo AJC
  • CONCLUSIONS: The value of ILR monitoring is strongly time- and indication-dependent. Prolonged routine monitoring or reimplantation appears to have limited incremental value in syncope and palpitations when early follow-up is unrevealing, whereas extended surveillance may remain justified in Brugada syndrome and should be individualized after cryptogenic stroke. These observations support indication-driven ILR follow-up strategies rather than a uniform approach based on device longevity alone.
