Summary

The purpose of this study to assess the longitudinal changes in left and right ventricular global strain after chemotherapeutic strategies in cardiac light chain amyloidosis.

Detailed description

Light chain amyloidosis is a disease characterized by localized or systemic accumulation of amyloid fibrils in tissues caused by abnormal folding of light chain immunoglobulins and affecting organ functions. In the treatment, chemotherapeutic agents are used that prevent the clonal proliferation of plasma cells in the bone marrow. Although the hematological response is standardized in evaluating the treatment response, there is no adequately effective method for assessing cardiac response. Despite the use of various scores, imaging-based systems continue to be developed to increase the sensitivity of these methods. After being informed about the study, it is planned to recruit and follow-up AL-Amyloidosis patients with cardiac involvement who are currently receiving/planned chemotherapy followed by hematology or who are planned for bone marrow transplantation within 1 year after obtaining written consent from the patients.

Conditions

• Amyloid Cardiomyopathy
• Congestive Heart Failure
• Chemotherapy Effect

Interventions

Type	Name	Description
DIAGNOSTIC_TEST	Left and Right Ventricular Global Strain Imaging	Two-dimensional, color Doppler, spectral Doppler, and 3D digital echocardiographic image recordings will be taken from parasternal, apical, subcostal, and modified sections using a Philips Epiq CVx echocardiography device and X5-1 probe. Conventional parameters, additional parameters, and strain analyzes will be performed with speckle tracking echocardiography from these recordings.
