Beyond The Expected Window: A Rare Presentation Of Acei-Associated Angioedema Two Decades Into Therapy, Taiwo Ajani, Jose J. Loayza Pintado, Renzo Aller Rojas, Jorge Aboytes Trevino, Michelle Lopez

Research Colloquium

Introduction: Angiotensin-converting enzyme inhibitor–induced angioedema (ACEI-AE) is a rare but potentially serious adverse effect of a widely used class of antihypertensives. It typically presents as non-pitting, non-pruritic swelling of the face, lips, tongue, or upper airway, often without associated urticaria. Although most cases occur within the first weeks of treatment, delayed presentations, sometimes after years of stable therapy, have been increasingly recognized. The condition is bradykinin-mediated and often does not respond to standard allergy medications such as antihistamines or corticosteroids.

Case Presentation: A 56-year-old woman with a medical history of hypertension, type 2 diabetes, GERD, and seasonal allergies presented to …

From Skin To Spleen To Brain: Full-Spectrum Embolic Complications In Staphylococcus Aureus Endocarditis, Jose J. Loayza Pintado, Jorge Aboytes Trevino, Julian Galindo, Mohammad Aqeel, John Cauba, Joshua Nwose, Andres Suarez Parraga

Research Symposium

Background: Infective endocarditis (IE) results from bacterial adhesion to endocardial tissue and valvular apparatus. While viridans group streptococci and Enterococcus species are associated with subacute disease, Staphylococcus aureus, including methicillin-resistant strains (MRSA), is a leading cause of more acutely destructive presentations. The entry of these pathogens can occur through surgical and dental procedures, intravenous drug use, or less apparent etiology. Classic peripheral stigmata (Osler nodes, Janeway lesions, splinter hemorrhages, Roth spots) are now uncommon but clinically meaningful. Current guidelines emphasize rapid multimodality imaging to detect cerebral and systemic emboli in symptomatic IE. We present a 50-year-old man with S. aureus …

The Bubble, The Blockage, And The Barrier: Weighing Pfo Against Moyamoya In An Stroke Mechanism Diagnostic Challenge In Down Syndrome With Achalasia, Jose J. Loayza Pintado, Adolfo Nava, Jose Donis Castaneda, Taiwo Ajani, Cesar Uribe

Research Symposium

Background: Paradoxical embolism through a PFO or small ASD is a common mechanism of stroke in young adults, and randomized trials plus contemporary guidelines support closure in carefully selected 18–60-year-olds to reduce recurrence. Individuals with Down syndrome frequently have congenital heart lesions, raising the pretest probability of shunt-mediated stroke. Yet Down syndrome is also linked to moyamoya arteriopathy, creating diagnostic ambiguity when intracranial narrowing is seen on first-pass imaging. We present a 34-year-old woman with Down syndrome, an acute MCA infarct, and a mildly positive bubble study in whom TEE was deferred for achalasia, illustrating a cardiology-led diagnostic challenge that …
