Abstract

39 patients affected with hypertrophic cardiomyopathy (ICM) have been studied by M-mode and two-dimensional echocardiography (1 and 2D Echo), standard electrocardiogram (ECG) and vectorcardiogram (VCG). For each patient we have outlined the anatomical shape of the left ventricle and we have tried to measure the myocardial hypertrophy by a score system that determines its size and extent. For this reason we have followed the echocardiographic segmental analysis procedure suggested by Edward (1981) but we have modified it dividing the left ventricle into 11 segments and measuring the value of the apex three times. We have given each patient a hypertrophy score by assigning a value 0 to any segment with a thickness less than or equal to 12 mm, a value 1 if the thickness was greater than 12 less than or equal to 17 mm, a value 2 if it was greater than 17 less than or equal to 22 mm, a value 3 if greater than 22 mm. We have also calculated the distribution index of the hypertrophy dividing the number of the hypertrophied segments by the number of the ventricular segments. We have identified five patterns of hypertrophic cardiomyopathy: 7 cases with a partial involvement of the interventricular septum (IVS) (pattern 1), 7 cases with ...Continue Reading

Cardiomyopathy

Cardiomyopathy is a disease of the heart muscle, that can lead to muscular or electrical dysfunction of the heart. It is often an irreversible disease that is associated with a poor prognosis. There are different causes and classifications of cardiomyopathies. Here are the latest discoveries pertaining to this disease.
