Hypertrophic cardiomyopathy occurs in some patients with congenital heart disease and should be suspected when the clinical course, cardiomegaly, or electrocardiogram is atypical.
Highlights the clinical and electrocardiographic signs that should raise suspicion for coexisting hypertrophic cardiomyopathy in patients with congenital heart disease.
Experience has shown that clinical hypertrophic cardiomyopathy (HOCM, ASH) occurs in some patients with congenital heart disease, particularly simple lesions with a good natural prognosis. Its presence should be suspected when the clinical course is atypical for the basic congenital lesion or when there is unexpected cardiomegaly, an associated left sided lesion or left ventricular hypertrophy in abnormalities which primarily affect the right side of the heart, or an atypical electrocardiogram showing QS patterns, left anterior hemiblock, deeply inverted septal T inversion, or unusual ST-T changes over the left ventricle.
Somerville et al. (Fri,) conducted a review in Congenital heart disease and hypertrophic cardiomyopathy. Hypertrophic cardiomyopathy occurs in some patients with congenital heart disease and should be suspected when the clinical course, cardiomegaly, or electrocardiogram is atypical.
