Diagnóstico y estudio de cardiopatías infrecuentes: multimodalidad – miocardiopatía hipertrófica

Abstract

Hypertrophic cardiomyopathy is a genetic disorder, characterised by left ventricular hypertrophy not explained by secondary causes, including non-dilated ventricle and preserved or augmented ejection fraction.1 Histologically, hypertrophic cardiac myocytes are observed that are disorganised, losing parallel alignment due to random orientation, and separated by wide areas of fibrosis.The estimated prevalence in the adult population is 1:625 – 1:344, no ethic, geographic or sex distribution patterns have been observed.2 Ventricular hypertrophy is the cornerstone in the diagnosis of hypertrophic cardiomyopathy. The presence of a ventricular wall greater than 15mm, suffices initially to consider the possibility of hypertrophic cardiomyopathy.The different imaging modalities in cardiology such as echocardiogram and cardiac resonance are fundamental in the diagnosis of the entity, and when determining prognosis and assessing response to treatment.
