The progression of hypertrophic cardiomyopathy: dilatation of the left ventricle with supernormal systolic function.
We performed cardiac catheterisation in a man who had been diagnosed as having hypertrophic cardiomyopathy 7 years earlier. The repeat angiogram showed the maintenance of a "supernormal" systolic function (ejection fraction: 87%) although there was an increase of left ventricular end-diastolic volume (from 65 to 132 ml/m2). This case suggests that progressive left ventricular dilatation should not necessarily be considered a marker of the progression of hypertrophic cardiomyopathy into a hypokinetic left ventricle.
