摘要
We report the case of a young woman with a troponin mutation of C to T nucleotide substitution in exon 17 of troponin 2 (TNNT2; c.868C.T; p.Arg288Cys) leading to hypertrophic obstructive cardiomyopathy. Following surgical resection of the outflow obstruction, she had near-complete resolution of her asymmetric left ventricular hypertrophy, such that cardiomyopathy could no longer be diagnosed on echocardiographic grounds We believe that this unusual case shows important aspects relating to the interplay between genetic and environmental mechanisms and the overlap in the phenotypic spectrum between primary subaortic stenosis and obstructive hypertrophic cardiomyopathy
