Although an increase in the ratio of ventricular space to brain (ventricle-brain ratio), VBR) on computed tomography (CT) has been among the most robust findings in chronic schizophrenia, VBR has not been investigated in a large, well-characterized clinical population of patients with schizotypal personality disorder (SPD), a clinical entity with a phenomenologic, gentle biological, and treatme...

Twenty-seven patients with acute myocardial infarction not complicated by cardiogenic shock and ten normal volunteers were studied with gated cardiac blood pool scans. The ratio right vetricular area/left ventricular area (RVA/LVA) determined from the left anterior oblique end-diastolic scans was examined. The ratio was 1.11 +/- .06 in the normal volunteers. In patients with anterior infarction...

BACKGROUND Left ventricular enlargement and the development of chronic heart failure are potent predictors of survival in patients after myocardial infarction. Prospective studies relating progressive ventricular enlargement in individual patients to global and regional cardiac dysfunction and the onset of late chronic heart failure are not available. It was the aim of this study to define the ...

Figure 1 (A and B) Right ventricular mass (arrowed) attached to the tricuspid valve chordae apparatus on echocardiography, in apical four-chamber view, and modified parasternal right ventricular inflow view respectively; (C and D) repeat echocardiogram demonstrating enlargement of the original mass and an additional mass (longer arrow), modified parasternal right ventricular i mass on computeri...

Resorption of the ventricular fluid was studied by measuring ventricular fluid outflow resistance during steady state 1.5 and 5.0 ml/min infusions in 26 patients with substantial enlargement of the supratentorial ventricular system. This test may avoid unnecessary use of shunts, but a shunt could be introduced during the same procedure.

OBJECTIVE To assess left ventricular function in adult Fallot patients with residual pulmonary regurgitation. SETTING The radiology department of a tertiary referral centre. PATIENTS 14 patients with chronic pulmonary regurgitation and right ventricular volume overload after repair of tetralogy of Fallot and 10 healthy subjects were studied using magnetic resonance imaging. MAIN OUTCOME M...

Patients—14 patients with chronic pulmonary regurgitation and right ventricular volume overload after repair of tetralogy of Fallot and 10 healthy subjects were studied using magnetic resonance imaging. Main outcome measure...

arrhythmogenic right ventricular dysplasia/cardiomyopathy (arvd/c) is a congenital cardiac disease with myocardial involvement, most probably right ventricular (rv) dysfunction, accounting for 20% of sudden cardiac deaths. characterized by the fibro-fatty infiltration of the rv free wall, arvd/c presents in adolescents with ventricular arrhythmias and heart failure symptoms and as biventricular...

Partial anomalous pulmonary venous connection (PAPVC) is a very rare congenital heart disease where one or more of the pulmonary veins are connected to the venous circulation. Although initially suspected with inexplicable right ventricular enlargement on transthoracic echocardiography, other modalities such as transesophageal echocardiography, CT angiography or cardiac Magnetic resonance (CMR)...
