Diverse types of cardiomyopathies (CM) were found in 16 out of these 38 patients (42%) with a mean LVEF of 33 ± 11%: hypertrophic (n = 4) (HCM), dilated CM (n = 3), ARVC (n = 2), cardiac sarcoidosis (n = 2), wild-type TTR cardiac amyloidosis (n = 1), significant aortic stenosis (n = 1), significant aortic regurgitation (n = 1), tako-tsubo (n = 1), mitral valve dystrophy (n = 1). This evidence concerns the gene TTR and cardiac amyloidosis.
