hypertrophic miocardiopathy

Manlio F Márquez, Teresita de Jesús Ruíz-Siller, Rosario Méndez-Ramos, Erick Karabut, Alberto Aranda-Fraustro, Silvia Jiménez-Becerra
Hypertrophic cardiomyopathy (HCM) is characterized by the presence of an abnormal hypertrophy of the left ventricle (LV), without dilation, and in the absence of any condition or another cardiac or systemic disease capable of inducing such hypertrophy. This primary or idiopathic hypertrophy can occur with or without dynamic obstruction (induced by exercise) of the LV outflow tract, so in its natural history two fundamental aspects are highlighted: the production of symptoms by blocking the LV outflow tract and the occurrence of sudden cardiac death secondary to ventricular arrhythmias...

Cardiac hypertrophy can occur as an adaptative response to increased cardiac workload. Different types of cardiac hypertrophy arise from a combination of genetic, physiologic, and environmental factors. When hypertophic growth of the heart leads to left ventricular dysfunction and heart failure, the response is considered as maladaptive or pathological hypertrophy. After analyzed left ventricular functional and structural changes in rats induced by arterial hypertension, banding of aortic root, isoproterenol administration, or myocardial infarction, as well as in patients with arterial hypertension, aortic stenosis, or hypertrophic miocardiopathy, we found a maladaptive response considered as pathological hypertrophy...

The form of presentation of a new case of Melas Syndrome is described, together with a pathological and neuroimage study, including clinical development over a 3 year period. The usefulness of MR should be underlined here, given clinical doubts, and also normality in the EMG early phases of and the association with obstructive hypertrophic miocardiopathy.
