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 ventricular outflow tract and of the left and right ventricular cavities, increased thickness of the interventricular septum and the posterior left ventricular wall. Comparision of the haemodynamic and echocardiographic data showed that some degree of abnormal mitral valve motion during systole may occur in the absence of left ventricular outflow tract obstruction. On the other hand, it need not always be present with left ventricular outflow tract obstruction. Other, hitherto unrecognized, abnormalities in hypertrophic cardiomyopathy detected by this technique were: (1) Aortic valve regurgitation in three out of nine patients with evidence of left ventricular cutflow tract obstruction at cardiac catheterization. (2) Left ventricular inflow tract obstruction at the mitral valve level associated with gross septal hypertrophy (five cases). (3) Abnormal forward displacement of the posterior mitral valve leaflet and of the chordae tendineae during systole in 10 patients, in seven of whom there was confirmatory angiocardiographic evidence. Seven patients with miscellaneous cardiac disorders are described in whom
asymmetric septal hypertrophy
was revealed by echocardiography. In one of these patients coexisting hypertrophic cardiomyopathy was excluded histologically; thus
asymmetrical
septal hypertrophy is not confined to patients with hypertrophic cardiomyopathy.

1. The performance of brown egg laying hens was compared under conventional and
asymmetrical
interrupted-lighting conditions. 2. Egg numbers and mean weight were similar under the two conditions, provided the apparent day perceived by the hen was the same under both lighting treatments. 3. Daily food intakes of intermittently-illuminated hens were not significantly lower than those of conventionally-lit birds. However, the reductions were of the magnitude reported in the literature and observed under commercial conditions. 4. Shell quality was unaffected by interrupted lighting in the period up to 60 weeks of age in two of the 4 genotypes studied. All breeds had lower shell weights under interrupted lighting in the last three months of lay. 5. Intermittently-lit hens had lower body weights, which approached significance, and significantly less carcase fat. There were no differences in
ash
, protein (N x 6.25) or water contents of the carcases, or in fat content at a given body weight. 6. There were no significant differences in the production responses of the 4-brown-egg hybrids to interrupted lighting. 7. Diets with differing concentrations of energy and protein were included in both trials, but there was no evidence of interaction between these nutritional treatments and the lighting treatments.

Four patients with Fabry's disease diagnosed by right ventricular endomyocardial biopsy had cardiac manifestations simulating hypertrophic cardiomyopathy (HCM). Case 1: A 51-year-old woman, whose elder sister had congestive heart failure, was hospitalized for exertional dyspnea and cardiomegaly. Her electrocardiogram (ECG) showed a short PQ interval (0.10 sec) and left ventricular hypertrophy. Her echocardiogram (Echo) showed moderate symmetrical hypertrophy of the left ventricle (IVST/PWT = 18 mm/17 mm). Case 2: A 32-year-old woman, whose elder sister had an abnormal ECG, was hospitalized for the ECG abnormalities consisting of a short PQ interval (0.10 sec) and ST-T changes in the left precordial leads. The Echo revealed mild symmetrical hypertrophy of the left ventricle (IVST = 13 mm, PWT = 13 mm). Case 3: A 44-year-old man was hospitalized for his ECG suggestive of left ventricular hypertrophy, and his Echo showed
asymmetrical
septal hypertrophy (
ASH
; IVST = 22 mm). Case 4: A 51-year-old man was hospitalized for his ECG showing high voltage in the left precordial leads, and his Echo showed
ASH
(IVST = 20 mm). The cardiac histopathological findings of these cases included cytoplasmic vacuolization by light microscopy, and electron-dense deposits consisting of parallel or concentric lamellae with periodic spacing, suggesting Fabry's disease. The urinary glycolipids of Case 1 were increased biochemically; then the diagnosis of Fabry's disease was confirmed. Cardiac hypertrophy in Fabry's disease has many aspects, because the histopathological changes and clinical manifestations are determined by genetic factors. It was concluded that Fabry's disease may be concealed in some patients with the clinical diagnosis of HCM.

A case of acute idiopathic myopericarditis with transient severe swelling and akinesis of the interventricular septum on echocardiograms was reported. A 35-year-old man was admitted to our CCU because of cardiogenic shock five days after the onset of "common cold". Electrocardiograms revealed low voltage and ST-segment elevation in all leads except for a VR and a VL. Serum CPK, GOT and LDH were slightly elevated. Echocardiograms showed severe
asymmetrical
septal hypertrophy (
ASH
, 20 mm), akinesis of the interventricular septum and moderate pericardial effusion. With improvement of the clinical course and of the hemodynamic data, the thickness and wall motion of the interventricular septum became normal. Serum antiviral antibodies were not elevated throughout the course. Transvenous percutaneous right ventricular endomyocardial biopsy revealed degeneration and fragmentation of the myofibrils with interstitial cellular infiltration and edema in the subacute phase (8th hospital day), but showed only focal fibrosis in the chronic phase. Coronary arteriograms and left ventriculograms in the chronic phase (50th hospital day) were normal. From these findings we can conclude that the severe transient
ASH
is due to myocardial inflammatory swelling.

The mode of right ventricular hypertrophy was assessed by two-dimensional echocardiography (2DE) for 24 patients with hypertrophic cardiomyopathy (HCM), and the results were compared with those of 51 patients with hypertension (HT). The patients with HT were categorized in four groups depending on the thickness of the interventricular septum (IVST) and left ventricular posterior wall (PWT): HT-
ASH
with both left ventricular hypertrophy (LVH) (IVST greater than or equal to 13 mm) and
asymmetric septal hypertrophy
(
ASH
) (IVST/PWT greater than or equal to 1.3), severe HT with LVH and without
ASH
, and mild HT without LVH and
ASH
. Anterior wall thickness (AWT), posterior wall thickness (PWT), and diaphragmatic wall thickness (DWT) of the right ventricle were obtained from 2DE in the parasternal long-axis view, the short-axis view and subxiphoid view, respectively. These were recorded on video tape, and the measurements were made on the stop frames. Right ventricular hypertrophy (RVH) was estimated by the maximal right ventricular wall thickness (max RVWT), and the ratio of the maximal and minimal thickness (max RVWT/min RVWT) was calculated to evaluate
asymmetrical
hypertrophy (AH) of the right ventricle (RV). The incidence of RVH (Max RVWT greater than or equal to 5 mm) and
asymmetrical
hypertrophy (AH) (max RVWT/min RVWT greater than or equal to 1.3) of the RV in HCM, HT-
ASH
and mild HT were 67% and 41%, 57% and 45%, and 15% and 11%, respectively. The incidence of RVH with AH was more frequent in patients with HCM as well as HT with
ASH
than in patients with HT without
ASH

To clarify clinically the pathogenesis of septal hypertrophy in terms of its morphology and wall dynamics, simultaneous biventricular cineangiography (BVG) and endomyocardial biopsy of the left ventricle were performed for patients with left ventricular hypertrophy. The patients were categorized in four groups according to their clinical and BVG findings; 1) 24 normal control subjects (C), 2) 39 patients with hypertension and symmetrical septal hypertrophy (SH-HT), 3) 17 patients with hypertension and
asymmetrical
septal hypertrophy characterized by the ratio (IVS/PW) greater than or equal to 1.3 by BVG, and 4) 25 patients with hypertrophic cardiomyopathy (HCM). The BVG's configuration of the septum in SH-HT showed a normal form of septal hypertrophy (NH form) essentially similar to that of the control subjects (N form), except for septal thickness increases of more than 10 mm. In HCM, a triangle or shell (TS) form or spindle (S) form of the septum was demonstrated by BVG. The TS form was characterized by straight or convex thickening of the septum from its center to its base toward the left ventricle. The S form was characterized by convex thickening localized to the central part and a relatively thin base. However, the configuration in
ASH
-HT was either the NH form (7 cases) or the TS or S form (10 cases). The configuration in
ASH
-HT with the NH form was not distinguishable from that of SH-HT, nor was the configuration in
ASH
-HT with the TS or S form distinguishable from that of HCM. Systolic thickening (%) of the septum and systolic shortening (%) of the septal length decreased significantly in this order: C, SH-HT,
ASH
-HT with the NH form, and
ASH
-HT with the TS or S form. Those of HCM were similar to those of
ASH
-HT with the TS or S form. In the cases of the N or NH form, there was a negative correlation between systolic thickening (%) and thickness of the septum in diastole. In cases with the TS or S form, systolic thickening (%) was not affected by the thickness of the septum in diastole, and a lower value was observed in all cases. Histological studies of endomyocardial biopsies revealed a positive correlation between the transverse diameters of the myocytes and the total systemic peripheral resistance (TSPR) in 25 patients with SH-HT. In 12 patients with HCM, there was no correlation, and severe hypertrophy of the myocytes was observed despite a lower TSPR.(ABSTRACT TRUNCATED AT 400 WORDS)

Cardiac amyloidosis typically presents with diastolic heart failure, but
asymmetrical
septal hypertrophy with outflow tract obstruction has been described. We illustrate the case of a 71-year-old woman with biopsy-proven cardiac amyloidosis and severe medical comorbidities with refractory severe heart failure who had
asymmetric septal hypertrophy
, systolic anterior motion (SAM) of the mitral valve, and a resting left ventricular outflow tract gradient of 86 mm Hg, increasing to 102 mm Hg on Valsalva maneuver. She underwent percutaneous transluminal septal myocardial ablation (PTSMA) with a dramatic resolution of her SAM and outflow tract obstruction, confirmed by intracavitary pressure wire measurements. PTSMA is technically feasible in this context, and correction of outflow tract obstruction may represent a new therapeutic target in cardiac amyloidosis.
