Prevalence of Cardiac Amyloidosis in Patients Undergoing Surgery for Lumbar Spinal Stenosis. (CASS-II)

January 26, 2023 updated by: Steen Hvitfeldt Poulsen

Patients undergoing surgery for lumbar spinal stenosis will have biopsies of the ligamentum flavum sent to the department of pathology for histologic screening.

If the ligament biopsy contains amyloid, patients will receive an echocardiogram, an ecg, biomarker testing, and a bone tracer scintigraphy diagnostic of cardiac amyloidosis.
