Tissue Doppler imaging to predict clinical course of patients with hypertrophic cardiomyopathy.
AIMS Diastolic tissue Doppler (TD) parameters allow prediction of patients with hypertrophic cardiomyopathy (HC) at risk of sudden death, ventricular tachycardia, or cardiac arrest. The aim of this study was to assess the value of TD imaging in predicting the clinical course of patients with HC. METHODS AND RESULTS Eighty-six HC patients were prospectively included in the study and followed-u...
متن کاملAssessment of diastolic function with Doppler tissue imaging to predict genotype in preclinical hypertrophic cardiomyopathy.
BACKGROUND Unexplained left ventricular hypertrophy (LVH) is considered diagnostic of hypertrophic cardiomyopathy (HCM) but fails to identify all genetically affected individuals. Altered diastolic function has been hypothesized to represent an earlier manifestation of HCM before the development of LVH; however, data regarding the clinical utility of imaging techniques that assess this paramete...
متن کاملTissue Doppler imaging predicts the development of hypertrophic cardiomyopathy in subjects with subclinical disease.
BACKGROUND Systolic (Sa) and diastolic (Ea) myocardial velocities measured by tissue Doppler (TD) imaging (TDI) recently were shown to be decreased in subjects who have mutations causing hypertrophic cardiomyopathy (HCM) but who do not have left ventricular (LV) hypertrophy. By studying these subjects at a later date, we sought to determine whether TDI predicts the subsequent evolution of the H...
متن کاملTissue Doppler imaging for the pre-clinical diagnosis of cardiomyopathy.
Duchenne muscular dystrophy is an important cause of cardiomyopathy in children and adolescents and is caused by mutations in the gene coding for the protein dystrophin [1]. Dystrophin participates in linking the sarcomere to the sarcolemma and extracellular matrix and plays a role in cell signalling [2]. The disease is characterised by skeletal and cardiac myopathies. Because it is inherited a...
متن کاملCharacterization of left ventricular diastolic function by tissue Doppler imaging and clinical status in children with hypertrophic cardiomyopathy.
BACKGROUND Conventional transmitral Doppler indices are unreliable in assessing clinical status in patients with hypertrophic cardiomyopathy (HCM) because they are affected by loading conditions. This study sought to determine whether tissue Doppler velocities are predictive of adverse clinical outcomes including death, cardiac arrest, ventricular tachycardia (VT), significant cardiac symptoms,...
