The neural crest origin of the aortopulmonary septum has led us to investigate the septum for a special function, and we designed the present study to assess the alteration, if any, in the dimensions of the aortopulmonary septum in hypertension. The dimensions of the aortopulmonary septum were measured by echocardiography in 36 hypertensive and 36 age- and sex-matched normotensive subjects. Ech...

Adequate growth of the hypoplastic right ventricle in a patient with severe pulmonary stenosis with an intact ventricular septum was documented after pulmonary valvotomy in infancy. It is postulated that the growth of the ventricular chamber is largely the result of pulmonary regurgitation resulting from successful pulmonary valvotomy. Based on this and the observations of others on the growth ...

Hypertrophic cardiomyopathy is a disease of cardiac muscle that is often genetically transmitted as. an autosomal dominant trait and is characterized by a wide variety of patterns of left ventricular hypertrophy that may be identified with wide-angle, two-dimensional echocardiography. To determine the degree to which left ventricular morphology is similar in related patients with hypertrophic c...

The relation between the superior orientation of the QRS axis and the anatomical site of the defect in the ventricular septum in patients with a ventricular septal defect was studied. Of 1031 patients with a ventricular septal defect, 64 (6.2%) had a superior axis on their electrocardiogram. In 59% of these patients the defect was in the inlet portion of the ventricular septum or affected this ...

Background. The mechanics involved in development of the inlet component of the morphologically right ventricle are, as yet, undecided. Some argue that this component is derived from the descending limb of the ventricular loop, and that the inlet and apical trabecular components of the muscular ventricular septum have separate developmental origins. Others state that the entirety of the right v...

Usefulness of two-dimensional and Doppler echocardiography in diagnosis of the ruptured interventricular septum in a course of myocardial infarction was evaluated basing on own material consisted of 6 cases. Ventricular septal defect was visualized in 5 patients. The blood flow through the ventricular septum was detected in all of 6 patients. Obtained results were concordant with intraoperative...

A case of development of monomorphic sustained ventricular tachycardia in the prehospital phase of acute myocardial infarction is reported. By performing pacing from the right ventricular outflow tract during ventricular tachycardia, constant fusion and progressive fusion were documented without constant and progressive fusion from the right ventricular apex pacing, and it was terminated by pac...

Computed tomography was undertaken in nine patients (age range 33-69 (mean 48.7) years) with hypertrophic cardiomyopathy. The ventricular septum was demonstrated in each patient and shown to be thickened (mean 25 mm at maximum width). The results agreed with those obtained by echocardiography, except in two patients in whom computed tomography showed preferential thickening of the mid-portion o...
