Palpitations are a symptom often reported by patients with apical hypertrophic cardiomyopathy (HCM), yet the arrhythmias associated with this type of HCM have not been studied adequately. Herein, a case of persistently recurrent atrial flutter in a 63-year-old Greek man with apical HCM is presented. Synchronized direct-current shocks were used twice during his hospitalization in order to conver...

Hypertrophic cardiomyopathy (HCM) is a common inherited heart disease with serious adverse outcomes, including heart failure, arrhythmias, and sudden cardiac death. The discovery that mutations in sarcomere protein genes cause HCM has enabled the development of mouse models that recapitulate clinical manifestations of disease. Studies in these models have provided unexpected insights into the b...

Hypertrophic cardiomyopathy (HCM) is common, inherited and characterised by unexplained thickening of the myocardium. The British Society Echocardiography (BSE) has recently published a minimum dataset for transthoracic echocardiography detailing core views needed standard echocardiogram. For patients with confirmed or suspected HCM, additional measurements are necessary. This guideline, theref...

Several advances in molecular genetics and cardiac imaging of patients with hypertrophic cardiomyopathy (HCM) have been developed in recent years. The commercially available genetic testing is currently used (a) to identify affected relatives in families known to have HCM and (b) to differentiate HCM from metabolic storage disorders and other HCM phenocopies. Cardiovascular magnetic resonance h...

Hypertrophic cardiomyopathy (HCM) is a genetic cardiovascular disease that predisposes individuals to the development of arrhythmias. The most common sustained arrhythmia is atrial fibrillation (AF). Compared with the general population, patients with HCM are more prone to the development of AF. To avoid embolic complications and the clinical deterioration caused by the development of AF in HCM...

Background Introduction CMR has become the leading technique to define the clinical impact of hypertrophic cardiomyopathy (HCM) providing complete coverage of both ventricles with high spatial resolution. Gadolinium delayed-enhancement (DHE) accurately identifies regions of myocardial fibrosis. Via CMR, innumerable studies have established that LVH is the predominant phenotypic expression of HC...

Background CMR has become the leading modality to define the clinical impact of hypertrophic cardiomyopathy (HCM) providing complete coverage of both ventricles with high spatial resolution. Late gadolinium enhancement (LGE) accurately identifies regions of myocardial fibrosis. Via CMR, innumerable studies have established that LVH and LGE are the predominant phenotypic expressions of HCM. It i...

Apical hypertrophic cardiomyopathy (AHCM) is a known entity since its first introduction by Sakamoto and Yamaguchi. However, unlike classical (HCM), it less explored in terms of associated diagnosis long-term outcomes. Given the increased availability utilization ultra-sophisticated cardiac imaging modalities, AHCM will be increasingly recognized as distinct, clinically significant variant HCM....

Hypertrophic cardiomyopathy (HCM) is characterized by asymmetric left ventricular hypertrophy, diastolic dysfunction and myocardial disarray. HCM is caused by mutations in sarcomeric genes, but in >40% of patients, the mutation is not yet identified. We hypothesized that FHL1, encoding four-and-a-half-LIM domains 1, could be another disease gene since it has been shown to cause distinct myopath...

OBJECTIVES We investigated the utility of the peak negative myocardial velocity gradient (MVG) derived from tissue Doppler imaging (TDI) for evaluation of diastolic dysfunction in patients with hypertrophic cardiomyopathy (HCM). BACKGROUND Hypertrophic cardiomyopathy is characterized by impaired diastolic function with abnormal stiffness and prolonged relaxation. However, it remains difficult...
