The aim of this study was to investigate the contribution of direct right-to-left ventricular interaction to left ventricular filling and stroke volume in 46 patients with pulmonary arterial hypertension (PAH) and 18 control subjects. Stroke volume, right and left ventricular volumes, left ventricular filling rate, and interventricular septum curvature were measured by magnetic resonance imagin...

noncompaction of the ventricular myocardium is an embryonic cardiomyopathy that is increasingly being recognized. noncompaction of lv myocardium, right ventricular myocardium, or both can occur in isolation, in congenital heart diseases, in valvular heart diseases, in neuromuscular disorders, skeletal abnormalities and in endocrinologic abnormalities. clinical manifestations of ventricular non-...

We investigated the effect of pacing from the atrium and various ventricular sites on the left ventricular end-systolic pressure-volume relation following autonomic blockade in a total of 10 dogs chronically instrumented to measure left ventricular pressure and determine left ventricular volume from three ultrasonic endocardial dimensions. During ventricular pacing, left ventricular end-diastol...

conclusions there is a significant increased incidence of mortality, prolonged hospitalization, and rehospitalization in symptomatic patients with severe tr. therefore, we recommend more aggressive approach toward tv repair or replacement in these patients regardless of pap and systolic function. results heart failure (50%) was the most cause of death. mean years of survival from diagnosis of s...

BACKGROUND AND OBJECTIVES Higher left ventricular volume is associated with death in patients with ESRD. This work investigated the effects of frequent hemodialysis on ventricular volumes and left ventricular remodeling. DESIGN, SETTING, PARTICIPANTS, & MEASUREMENTS The Frequent Hemodialysis Network daily trial randomized 245 patients to 12 months of six times per week versus three times per ...

The QRS amplitude, duration, and mean axis direction of the standard 12-lead electrocardiogram were compared with left ventricular mass, volume, wall thickness, and stroke work in 112 adult patients. These patients had normal left ventricles or various degrees of left ventricular dilatation or hypertrophy. Left ventricular volumes and mass were determined by a quantitative angiocardiographic me...

Left ventricular function, pressure-volume relationships, and wall motion were studied by sequential cineventriculography during acute myocardial ischemia, induced by atrial pacing, in 10 subjects. Observations made in this group were contrasted to data obtained during atnal pacing in a smaller normal group. An acute alteration in the pressure-volume relation occurred in five subjects during is...

It has been shown in man that myocardial ischemia, whether precipitated by exercise or pacinginduced tachycardia, is associated with abnormalities of left ventricular end-diastolic pressure. There has been controversy as to whether this relationship is due to decreased myocardial compliance or to an increase in left ventricular volume as a manifestation of left ventricular failure. Simultaneous...

The accuracy of determining left ventricular function from echocardiography was assessed in 26 children (group I) with cineangiographically-determined normal left ventricular volume (LVV) and 28 children (group II) with large left ventricular volumes. Conventional LV echo dimensions were compared to the cineangiographic LV anterior-posterior minor axis (LVmA) and LVV. Very good correlations wer...
