In several patients with asymmetric septal hypertrophy (ASH) diagnosed by echocardiography (septal-free wall thickness ratios greater than or equal to 1.3), we have discovered marked discrepancies between the echocardiographic and necropsy measurements of wall thicknesses that led to uncertainty regarding the actual cardiac diagnosis. To resolve these apparent incongruities, the echocardiograms...

OBJECTIVES The purpose of this study was to determine the spectrum of left ventricular hypertrophy and ventricular morphology in adults with hypertrophic cardiomyopathy due to mutations of the beta-myosin heavy-chain gene. BACKGROUND Although echocardiography is an important test in diagnosing hypertrophic cardiomyopathy, the lack of an independent diagnostic criterion has been an obstacle in...

patients and methods forty five young female volunteer athletes were included and received different training regimens (endurance-training, strength training and concurrent groups) for a 10 week period as study intervention. standard color doppler echocardiography was performed for assessment of the left ventricular activity. results as a result, 45 athletes ended the study training regimens. m...

Hypertrophic cardiomyopathy (HCM) is defined as myocardial hypertrophy in the absence of another cardiac or systemic disease capable of producing the magnitude of present hypertrophy. In about 70% of patients with HCM, there is left ventricular outflow tract (LVOT) obstruction (LVOTO) and this is known as obstructive type of hypertrophic cardiomyopathy (HOCM). Cases refractory to medical treatm...

In a heart with hypertrophic cardiomyopathy without asymmetrical septal hypertrophy the number of transmural myocytes, the mean size of myocytes, and the percentage area of interstitial space were similar in the ventricular septum and left ventricular posterior wall, whereas in a reported series of 14 hearts with hypertrophic cardiomyopathy with asymmetrical septal hypertrophy the number of tra...

Background Echocardiography (ECHO) is used for diagnosis and management of hypertrophic cardiomyopathy (HCM). Morphologic diagnosis is based on the presence of myocardial thickness of >15mm in adults or a septum to posterior wall ratio of >1.5. Septal wall thickness (WT) >30 mm is one of several high risk features that are used to guide the decision for prophylactic implantable cardioverter-def...

Treatment of obstructive hypertrophic cardiomyopathy remains challenging. Medical therapy, surgical therapy, and pacemaker therapy have been shown to be beneficial in some patients over the years. Alcohol septal ablation is a catheter-based intervention that causes a controlled infarct in the septum leading to a decrease in the left ventricular outflow tract obstruction. Along with the impressi...

We determined functional and morphological changes of the heart by 2-dimensional and pulse Doppler echocardiography in 20 patients with primary aldosteronism and compared the results with those in 50 healthy normotensive subjects, 12 patients with Cushing's syndrome, 9 patients with pheochromocytoma, and 47 patients with essential hypertension. All hypertensive groups had greater left ventricul...

BACKGROUND Hypertrophy and concentric remodeling of the left ventricle are important manifestations of hypertension that are associated with increased morbidity and mortality. Although lifestyle interventions are efficacious in lowering blood pressure, evidence that they have a beneficial effect on target organs has been lacking. OBJECTIVE To assess the effects of regular aerobic exercise or ...
