background: hypertrophic cardiomyopathy is a genetic disorder with a prevalence rate of 0.2% in the general population. it comes from mutations in sarcomeric proteins. cardiac myosin-binding protein c3 is one of the critical genes in hypertrophic cardiomyopathy (hcm) and sudden cardiac death, accounting for about 20% of hcm-causing mutations. genetic testing is recommended in patients with hcm....

AIMS To evaluate acute and long-term symptomatic, haemodynamic (at rest and during exercise) and electrophysiological results of transcoronary ablation of septal hypertrophy (TASH), a catheter interventional treatment for hypertrophic obstructive cardiomyopathy. METHODS AND RESULTS Sixty-two transcoronary ablations of septal hypertrophy were performed by injection of 4.6+/-2.6 ml 96% ethanol ...

Whether apical hypertrophic cardiomyopathy is a variant of classic hypertrophic cardiomyopathy or a separate entity is controversial. This is a case report of an apical hypertrophic cardiomyopathy. The patient was a 67-year-old man associated with giant negative T waves in electrocardiogram and asymmetric apical hypertrophy on echocardiogram. He died of liver cirrhosis and liver cell carcinoma....

The clinical and morphologic features of hypertrophic cardiomyopathy in 20 patients recognized as having cardiac disease in the first year of life are described. Fourteen of these 20 infants were initially suspected of having heart disease solely because a heart murmur was identified. However, the infants showed a variety of clinical findings, including signs of marked congestive heart failure ...

Left ventricular systolic function does not correlate well with functional class in patients with dilated cardiomyopathy. To determine whether the correlation is better with Doppler indexes of left ventricular diastolic function, 34 patients with dilated cardiomyopathy (M-mode echocardiographic end-diastolic dimension greater than 60 mm, fractional shortening less than 25%, increased E point-se...

PURPOSE OF REVIEW Hypertrophic cardiomyopathy is the most common identifiable cause of sudden death in the young. This review details the history of hypertrophic cardiomyopathy, recent discoveries in its genetic underpinnings and important genotype-phenotype relationships described in recent studies. RECENT FINDINGS Since the discovery of the genetic underpinnings of hypertrophic cardiomyopat...

Over a 3 year period we evaluated 23 patients (16 men, seven women) with apical hypertrophic cardiomyopathy by noninvasive and invasive methods. Sixteen patients had chest pain. In 17, results of cardiovascular examination were normal. The electrocardiogram showed precordial inverted T waves in all patients and these were of mild-to-moderate amplitude (<10 mm) in 18 and giant (>10 mm) in five. ...

Apical hypertrophic cardiomyopathy is part of the broad clinical and morphologic spectrum of hypertrophic cardiomyopathy. We report a patient with electrocardiographic abnormalities in whom acute coronary syndrome was excluded and apical hypertrophic cardiomyopathy was demonstrated by careful differential diagnosis.
