Detecting cardiac amyloidosis in people with severe aortic valve narrowing

Official title: Non-Interventional Study on the Prevalence of Cardiac Amyloidosis in Patients With Higher-Grade Aortic Valve Stenosis - Evaluation Using Echocardiography, Computed Tomography, Tc99-SPECT/CT and Cardiac Magnetic Resonance Imaging (CMR)

Run by University Hospital Tuebingen · NCT07752732 · Data updated 2026-11-12

This study tests non-invasively whether imaging tests can find heart amyloidosis in patients with severe aortic stenosis who are being evaluated for valve replacement.

Is this trial a fit for you?

Likely a good fit

Adults ≥18 years with severe aortic valve stenosis undergoing evaluation for TAVI and suspected cardiac amyloidosis, who are able to undergo Tc-99m SPECT/CT, CT, and possibly CMR.

Probably not a fit

Patients without cardiac amyloidosis or those unable to complete the imaging procedures may derive no direct benefit.

What this trial studies

This prospective observational study uses multimodal imaging to detect cardiac amyloidosis in adults with severe aortic valve stenosis considered for TAVI. It employs Tc-99m SPECT/CT and CT to measure amyloid-related tracer uptake and tissue characteristics, with CMR added when available. The goal is to see if these imaging biomarkers can identify amyloidosis before or during TAVI planning. Results may clarify how coexisting amyloidosis influences outcomes and management. The study is conducted at University Hospital Tübingen with collaboration from Bayer.

Why it matters

Potential benefit: If successful, the approach could enable earlier, non-invasive detection of cardiac amyloidosis to guide treatment decisions for patients with aortic stenosis.

How similar studies have gone: Previous data show Tc-99m phosphonate scintigraphy has high specificity for non-invasively identifying cardiac amyloidosis in this context, supporting the novelty and potential usefulness of this approach.
