NCT06186167

Brief Summary

This single-practice prospective cohort study aims to enhance the diagnosis of cardiac amyloidosis in high-risk patients undergoing standard cardiac device implantation. By analyzing chest wall fat tissue, which is usually discarded, we aim to determine the diagnostic yield of such biopsies for amyloidosis and to develop a predictive screening model based on clinical, lab, and imaging data. The study, running from December 2023 to December 2024, expects to enroll 100 patients and may provide a new, non-invasive diagnostic avenue for this condition.

Outcome Measures

Primary Outcomes (1)

  • Diagnostic yield of chest wall fat pad biopsy for cardiac amyloidosis

    The primary outcome measure is the histopathologic diagnosis of amyloidosis in chest wall fat tissue removed during cardiac device implantation

    December 2023 to December 2024, corresponding to the study duration during which patients will be enrolled and outcomes will be assessed

Secondary Outcomes (1)

  • Development of a predictive screening model for cardiac amyloidosis

    Retrospective analysis of patient data collected from December 2023 to December 2024

Study Arms (1)

High-Risk Cardiac Device Recipients

Participants in this cohort are individuals undergoing clinically indicated cardiac device implantation, such as pacemakers, ICDs, ILRs, or CRT-D/Ps. During the standard implantation procedure, chest wall fat tissue typically excised to create space for the device is collected for histopathological analysis to identify amyloid deposits. This study involves no additional intervention beyond the routine clinical care received by the patients.

Procedure: Chest Wall Fat Tissue Collection

Interventions

As part of routine cardiac device implantation, chest wall fat tissue is collected for histopathological analysis. This tissue, which is typically discarded, will be used to identify amyloid deposits in high-risk cardiac patients. No additional surgical intervention is performed beyond the standard procedure for device implantation.

Biospecimen

Retention: SAMPLES WITH DNA

The biospecimens consist of chest wall fat tissue samples collected during cardiac device implantation procedures. This adipose tissue, typically excised to create space for the device, is preserved for histopathological analysis to detect amyloid deposits. The analysis of these samples is crucial for diagnosing cardiac amyloidosis in patients at high risk. The tissue will be handled and analyzed by the HCA pathology laboratory, following standard procedures to ensure the integrity of the samples and the accuracy of the diagnostic results.
