A novel genotype–phenotype overlap: transthyretin cardiac amyloidosis with a pathogenic CTNNA3 truncating variant presenting with malignant ventricular arrhythmias

2026-06-16

Abstract excerpt

<title>Abstract</title> <p>Background: Transthyretin cardiac amyloidosis (ATTR-CM) may mimic hypertrophic cardiomyopathy and, in rare cases, coexist with genetic cardiomyopathies, potentially increasing arrhythmic risk. <h4>Methods:</h4> An 82-year-old man with atrial fibrillation presenting with progressive heart failure symptoms underwent comprehensive clinical, electrocardiographic, echocardiographic, hematol...
