Left ventricular diastolic gradient in hypertrophic cardiomyopathy☆
Systolic left ventricular (LV) gradients and diastolic dysfunction are widely studied in hypertrophic cardiomyopathy (HCM) [1,2], however diastolic gradients have never been described. A patient with HCM, mid-cavity obliteration and apical aneurysm, diagnosed by both 2D echocardiography (Fig. 1, panel A) and cardiac magnetic resonance (Fig. 1, panel B), showed color Doppler aliasing effect at m...
متن کاملSpeckle tracking echocardiography to assess regional ventricular function in patients with apical hypertrophic cardiomyopathy
AIM To explore regional systolic strain of midwall and endocardial segments using speckle tracking echocardiography in patients with apical hypertrophic cardiomyopathy (HCM). METHODS We prospectively assessed 20 patients (mean age 53 ± 16 years, range: 18-81 years, 10 were male), with apical HCM. We measured global longitudinal peak systolic strain (GLPSS) in the midwall and endocardium of th...
متن کاملLeft ventricular short-axis systolic function changes in patients with hypertrophic cardiomyopathy detected by two-dimensional speckle tracking imaging
BACKGROUND Hypertrophic cardiomyopathy (HCM) is a genetic disease was characterised by left ventricular hypertrophy (LVH), myocardial fibrosis, fiber disarray. The short-axis systolic function is important in left ventricle function. METHODS Forty one healthy subjects and 37 HCM patients were enrolled for this research. Parasternal short-axis at the basal, middle, and apical levels were acqui...
متن کاملLeft ventricular opacification during selective intracoronary injection of echocardiographic contrast in patients with hypertrophic cardiomyopathy.
Percutaneous alcohol ablation of the interventricular septum via the first septal perforator branch of the left anterior descending artery can successfully treat dynamic left ventricular outflow tract obstruction in patients with hypertrophic cardiomyopathy. Increasingly, echocardiographic contrast agents are used before alcohol injection to identify the perfusion bed of the septal perforator v...
متن کاملLeft atrial dysfunction in light-chain cardiac amyloidosis and hypertrophic cardiomyopathy - A comparative three-dimensional speckle-tracking echocardiographic analysis from the MAGYAR-Path Study.
INTRODUCTION While cardiac amyloidosis (CA) is a rare systemic disease characterized by extracellular deposition of protein-derived fibrils, hypertrophic cardiomyopathy (HCM) is histopathologically characterized by myocyte hypertrophy and disarray, interstitial fibrosis, and small intramural coronary arteriole dysplasia. The aim of the present study was to compare left atrial (LA) volumetric an...
