Detection of Cardiac Amyloidosis Using Right Ventricular Sensing Amplitude in Patients With Left Ventricular Hypertrophy
This multicenter prospective study aims to evaluate the diagnostic performance of right ventricular sensing amplitude measured during cardiac implantable electronic device (CIED) implantation (pacemaker or defibrillator) to identify cardiac amyloidosis in patients with left ventricular hypertrophy and conduction abnormalities.
Patients aged 65 years or older referred for CIED implantation will be included. During the procedure, electrophysiological parameters will be recorded.
Additional assessments will be performed, including cardiac scintigraphy, biological analyses, and subcutaneous adipose tissue biopsy. The results of these investigations will be used to confirm or rule out cardiac amyloidosis.
Diagnostic performance will be assessed using the area under the receiver operating characteristic curve (AUROC).
