Between 1981 and 1992 a total of 10 patients with hypertrophic cardiomyopathy (HCM) were detected by mass screening for heart disease in Tokyo's Adachi Ward. Four were first grade elementary school children and six were first grade junior high school adolescents. Two-dimensional echocardiography at the initial evaluation revealed asymmetric septal hypertrophy in four patients, diffuse hypertrophy of the left ventricle in five, and poor left ventricular contractility with wall thinning in one (dilated phase). Three of the five patients with diffuse hypertrophy progressed to asymmetric septal hypertrophy during the average 4-year follow-up period. The degree of septal thickness and the left ventricular wall thickness index were significantly less than in those of young adult controls (12 +/- 3 versus 21 +/- 9 mm, p < 0.05; and 22 +/- 4 versus 28 +/- 16 mm, p < 0.05, respectively). Right ventricular endomyocardial biopsy specimens obtained from 9 of the 10 patients showed features typical of HCM (e.g., myocyte hypertrophy with myofibril disarray) in five patients and atypical features (mainly interstitial fibrosis with perivascular cell infiltration) in another four. One patient with dilated phase disease died of congestive heart failure 6 months after the initial evaluation. These results indicate that HCM detected during mass screening is a mild form of the disease and may have atypical pathologic features, such as interstitial fibrosis and perivascular cell infiltration, mimicking the sequela of chronic myocarditis.

Twelve patients with Friedreich's ataxia (FA) were evaluated clinically and echocardiographically for evidence of heart disease. Electrocardiographic and echocardiographic abnormal findings were discovered in eight (67%) and seven (58%) children, respectively. A high incidence of cardiac involvement is well known in FA cases. Although the patient number in the present study is small, the findings are consistent with those in the literature. The most common pathology was asymmetric septal hypertrophy (ASH), followed by concentric left ventricular hypertrophy (CLVH) and dilated cardiomyopathy (DC).

A 59-year-old man with hypereosinophilic syndrome (HES) who had been maintained with low-dose prednisolone for 5 years developed the characteristic features of hypertrophic cardiomyopathy. Left ventricular endomyocardial biopsy revealed no eosinophilic infiltration but extensive myocardial fibrosis. Cardiac involvement in HES presents as endocardial fibrosis, resulting in a clinical presentation of restrictive cardiomyopathy. HES heart disease can also present dilated cardiomyopathy, but myocardial hypertrophy has only rarely been noted in conjunction with HES. This report concerns a patient with HES who had clinical and hemodynamic evidence of asymmetric septal hypertrophy with mid-ventricular obstruction.

Double-chambered right ventricle (DCRV) is an uncommon congenital heart disease. Anomalous muscle bundles in the right ventricle divide the right ventricle into two portions and cause intracavitary obstruction of the right ventricle. We report a patient with DCRV mimicking asymmetric septal hypertrophy. We did clinical, echocardiographic and angiographic evaluation. Surgical intervention was successfully managed.

Hypertrophic cardiomyopathy (HCM) is classified as a primary cardiomyopathy. HCM is a clinically heterogeneous but relatively common autosomal dominant genetic heart disease that probably is the most frequently occurring cardiomyopathy. HCM is characterized morphologically and defined by a hypertrophied, nondilated left ventriculum (LV) in the absence of another systemic or cardiac disease that is capable of producing the magnitude of wall thickening evident (e.g., systemic hypertension, aortic valve stenosis). Most HCM patients have the propensity to develop dynamic obstruction to LV outflow under resting or physiologically provocable conditions, produced by systolic anterior motion of the mitral valve with ventricular septal contact. The phenotypic features of HCM may develop at any age from infancy to adulthood, and are characterized by a great heterogeneity in the extent, magnitude, and distribution of left ventricular hypertrophy. Hypertrophic obstructive cardiomyopathy (HOCM) often leads to heart failure, severe ischemia, severe symptoms and death. Determination of the exact site of the hypertrophy and of the obstruction of the left ventricular outflow tract, in asymmetric septal hypertrophy, establishes which is the best treatment strategy. In the treatment of HOCM, drug therapy with negatively inotropic drugs, percutaneous transluminal septal myocardial ablation by alcohol-induced septal branch occlusion, surgical myectomy and DDD pacemaker therapy are considered the therapeutical options. We present a case of an obstructive hypertrophic cardiomyopathy in an 84-year-old Italian woman with a left ventricular outflow tract (LVOT) peak gradient with the Valsalva maneuver of 188 mm Hg and with a history of first episode of syncope.
