Abstract

Hypertrophic cardiomiopathy is a peculiar process with different anatomical and functional abnormalities which are present in different degrees in each case. Echocardiography and Doppler techniques have contributed definitively to the knowledge of this process and these procedures are choices for establishing the diagnosis of hypertrophic cardiomyopathy and to evaluate the clinical and morphological diversity of this process consisting of a spectrum of abnormalities with a variable presence in each case. Disproportionate septal hypertrophy is the most frecuent finding but the hypertrophy can involve other segments and different patterns can be present; concentric hypertrophy, apical, involving right ventricle, inverted asymetric, etc. Anterior mitral valve motion can be produced by the interrelation between anatomic factors of the valve, geometry of the outflow tract and physical forces produced by flow changes. Doppler echocardiography allows us to evaluate subaortic obstruction, to define its site, to demonstrate and measure the degree of mitral regurgitation and to carry out intraoperative studies. In hypertrophy cardiomyopathy the pattern of delayed relaxation is the most frequent but patients with severe obstruction and mi...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.
