Analyzing Calcium Scores in Patients with Severe Aortic Stenosis and Cardiac Amyloidosis

Analysis of Calcium Score Values of Severe Aortic Stenosis in Patients With and Without Cardiac Amyloidosis (CAUSATIVE Study)

Observational University Hospital of Ferrara · NCT06066632

This study is trying to see how calcium buildup in the heart affects the severity of aortic stenosis in patients who also have cardiac amyloidosis.

What this trial studies

This observational study aims to investigate the relationship between valvular calcium scores, assessed through EKG-gated CT, and effective orifice area, evaluated via echocardiogram, in patients with severe aortic stenosis who may also have cardiac amyloidosis. The study focuses on understanding how the presence of cardiac amyloidosis affects the estimation of aortic stenosis severity, particularly in cases with paradoxical low-flow, low-gradient profiles. By confirming preliminary findings that suggest patients with both conditions may have less calcium deposition, the study seeks to enhance diagnostic accuracy and treatment strategies for this dual pathology.

Who should consider this trial

Good fit: Ideal candidates for this study are patients aged 65 and older with severe aortic stenosis who are planned for or have undergone TAVI or SAVR and show signs suggestive of cardiac amyloidosis.

Not a fit: Patients with suboptimal acoustic windows that hinder the assessment of aortic stenosis severity may not benefit from this study.

Why it matters

Potential benefit: If successful, this study could lead to improved diagnostic methods and treatment strategies for patients suffering from both severe aortic stenosis and cardiac amyloidosis.

How similar studies have performed: Preliminary findings from small case series suggest that the approach taken in this study may yield significant insights, although it remains to be fully validated in larger cohorts.
