Brief Summary:

Wild-type transthyretin cardiac amyloidosis is an underdiagnosed depository disease in which fibril monomers of misfolded amyloid protein accumulates in various tissues, including the heart, and cause tissue dysfunction.

Before onset of cardiac symptoms, many patients will have undergone surgery for idiopathic carpal tunnel syndrome since the protein also deposits in the transversal carpal ligament of the hand.

This study investigates patients previously operated for idiopathic carpal tunnel syndrome to determine if they display signs and symptoms of cardiac amyloidosis.
