this is a case of severely stunned left ventricle which occurred after a non-st elevation myocardial infarction in a 76-year-old woman who was a known case of three-vessel disease. her symptoms and cardiac function responded well to revascularization.

The exercise hemodynamic values in two groups of patients with repaired tetrad of Fallot (eight patients with some residual pulmonary insufficiency and seven patients without insufficiency) were compared with values in seven patients with trivial pulmonary stenosis who had not been operated on. The patients with tetrad of Fallot underwent surgery after age 8 years and all had a good hemodynamic...

OBJECTIVE To assess right and left ventricular systolic function in normal human fetuses by cross sectional Doppler echocardiography to calculate the force developed by myocardial shortening. DESIGN Cross sectional echocardiographic images of the aorta and pulmonary arteries were obtained prospectively in order to measure great vessel diameters and calculate their cross sectional areas. Doppl...

although involvement of the heart by malignant lymphoma is relatively common, it is unusual to be detected premortem. we report a case of hodgkin's lymphoma who presented with systemic signs and symptoms including abdominal distension, weakness, pallor, chills and fever, hepatosplenomegaly and generalized lymphadenopathy as well as signs of heart failure. echocardiography revealed lucent myocar...

BACKGROUND Echocardiography is the most convenient method used to evaluate right ventricular function, and several echocardiographic parameters were studied in previous studies. But the value of these parameters to assess the right ventricular function in patients with pulmonary arterial hypertension (PAH) has not been well defined. METHODS Patients with PAH were observed prospectively. Right...

a pulmonary embolus clogs the artery that provides blood supply to a part of the lung. the embolus not only prevents the exchange of oxygen and carbon dioxide but also decreases blood supply to the lung tissue itself, potentially causing the tissue to die (infarct). a 52-year-old man presented with syncope and anxiety. he had sinus tachycardia and dilated right ventricle with trabeculations. a ...

To differentiate between the hemodynamic effects of afterload reduction produced by sodium nitroprusside (NP) and the effects of preload, left ventricular function curves were constructed during and without NP infusion at the same, normal left ventricular filling pressure (LVFP) levels for 20 patients 8 hours after coronary bypass grafting and for 10 of these patients preoperatively. Preoperati...

introduction: the correlation between right and left ventricular ejection fractions (rvef and lvef, respectively) has been studied in only a small number of patients with a marked decrease in rvef and lvef. the aim of the present study was to compare lvef and rvef in patients with ischemic heart disease. rvef and lvef were measured by cardiovascular magnetic resonance (cmr) imaging. materials a...

Left ventricular function, oxidative metabolism, and coronary blood flow were evaluated in 11 patients with chronic cor pulmonale (mean age 53 years) at rest and during stress, and compared with 11 normal subjects (mean age 29 years) studied under similar conditions. The left ventricles of patients with chronic cor pulmonale were normal in regard to contractile state, preload, afterload, corona...

BACKGROUND Electrical fusion between left ventricular pacing and spontaneous right ventricular activation is considered the key to resynchronisation in sinus rhythm patients treated with single-site left ventricular pacing. AIM Use of QRS morphology to optimize device programming in patients with heart failure (HF), sinus rhythm (SR), left bundle branch block (LBBB), treated with single-site ...
