Echocardiographic patterns in 15 patients with hypertrophic cardiomyopathy were compared with those in 30 healthy persons. Correlations with angiocardiographic data indicated that most of the anatomical abnormalities in hypertrophic cardiomyopathy can be assessed reliably by echocardiography. These include abnormal mitral valve motion, a reduction of the anteroposterior dimension of the left ve...

background: familial hypertrophic cardiomyopathy (hcm) is caused by mutations in genes encoding cardiac sarcomere proteins. nowadays genetic testing of hcm plays an important role in clinical practice by contributing to the diagnosis, prognosis, and screening of high-risk individuals. the aim of this study was developing a reliable testing strategy for hcm based on linkage analysis and appropri...

BACKGROUND Apical hypertrophic cardiomyopathy (ApHCM) is a relatively rare form of hypertrophic cardiomyopathy that predominantly affects the apex of the left ventricle and typically has a nonobstructive physiology. Its variable presentation and clinical course render ApHCM a commonly delayed or missed diagnosis. CASE REPORT A 53-year-old Caucasian woman presented with chronic progressive chest...

Dynamic obstruction to left ventricular outflow in patients with hypertrophic cardiomyopathy usually occurs when the anterior mitral leaflet moves forward in systole and approaches or contacts the ventricular septum. However, we have recently identified, by M mode and two-dimensional echocardiography, 21 patients with hypertrophic cardiomyopathy who had a unique pattern of mitral valve motion c...

Hypertrophic cardiomyopathy (HCM) is the most common genetic cardiovascular disease, which is caused by a multitude of mutations in genes encoding proteins of the cardiac sarcomere (1). Apical hypertrophic cardiomyopathy (AHCM) is an uncommon type of HCM. The sudden cardiac death is less likely to occur in the patients inflicted with AHCM (2). Herein, we presented the case of a 29-year-old man ...

An echocardiogram performed on a 72-year–old man with exertional dyspnea revealed asymmetrical septal hypertrophy (maximum thickness, 1.8 mm) and turbulent flow in the left ventricular outflow tract (LVOT; Movie I in the onlineonly Data Supplement) with a resting gradient of 62 mm Hg and a peak provoked gradient of 166 mm Hg after Valsalva maneuver (Figure, A and B), consistent with hypertrophi...

Despite considerable interest in the syndrome of acute left ventricular (LV) ballooning, its pathophysiology has remained ill-defined. In this review, we explore observational data describing two etiologies LV ballooning: neurohumoral classic Takotsubo Syndrome (TTS), and severe unrelenting outflow tract (LVOT) obstruction patients with obstructive hypertrophic cardiomyopathy (HCM). We describe...

BACKGROUND Alcohol septal ablation (ASA) therapy results in clinical and hemodynamic improvement in patients with hypertrophic obstructive cardiomyopathy. However, a subset remains symptomatic afterward, requiring additional procedures. We sought to examine the determinants of an unsatisfactory outcome, defined as unchanged symptoms with <50% reduction of baseline left ventricular outflow tract...
