ACCEL Lite: Featured ACCEL Interviews on Exciting CV Research

Ascending aortopathy (AA) is typically asymptomatic and often diagnosed incidentally, with surgical aortic replacement recommended once aneurysmal thresholds are reached. Emerging evidence suggests that indexing aortic size to patient height may more accurately identify individuals who could benefit from earlier intervention. For AA patients who do not currently meet guideline-based criteria for surgery, the aim is to assess how height-indexed aortic measurements influence longer‑term clinical outcomes in this population.    In this interview, Glenn A. Hirsch MD, MHS, FACC and Milind Y. Desai, MD, MBA, FACC discuss "Should There Be a Reappraisal of Surgical Threshold in Patients with Ascending Aortic Dilation?". 

In this interview, C. Noel Bairey Merz MD, MACC and Alison L.

Multimodality imaging plays a pivotal role in evaluating inflammatory cardiomyopathy, particularly when cardiac sarcoidosis (CS) is suspected. Symptoms of CS include unexplained high-grade AV block, ventricular arrhythmias, reduced left ventricular function, or regional wall thinning without coronary disease. The best evaluation combines cardiac magnetic resonance imaging (MRI) for structural and scar assessment with fluorodeoxyglucose (FDG)-positron emission tomography (PET) for detecting active inflammation and extracardiac involvement.    In this interview, Michelle Kittleson MD, FACC and Ron Blankstein, MD, FACC discuss "Multimodality Imaging in Inflammatory Cardiomyopathy."  Subscribe on Apple Podcasts | Subscribe to ACCEL
