background: the prevalence of patients with severe left ventricular dysfunction (lvd) referred for coronary artery bypass grafting (cabg) is increasing. preoperative lvd is an established risk factor for early and late mortality after revascularization. the aim of the present study was to assess the early outcome of patients with severe lvd undergoing cabg. methods: between december 2012 and no...
Increased pulmonary vascular pressure and decreased right-ventricular performance may occur following pneumonectomy. Inhaled nitric oxide decreases right-ventricular afterload and improves cardiac index by selectively decreasing pulmonary vascular resistance without causing systemic hypotension. We report the use of inhaled nitric oxide in a patient with acute right-ventricular dysfunction afte...
Introduction: In patients who underwent surgery to repair Tetralogy of Fallot, right ventricular dilation from pulmonary regurgitation may be result in right ventricular failure, arrhythmias and cardiac arrest. Hence, pulmonary valve replacement may be necessary to reduce right ventricular volume overload. The aim of present study was to assess the effects of pulmonary valve replacement on rig...
Pulmonary artery pressure can be estimated from right ventricular-right atrial pressure gradient in patients with tricuspid regurgitation. The most common approach is to estimate pulmonary artery systolic pressure from right ventricular pressure (assuming no pulmonic stenosis) determined as the sum of the right ventricular-right atrial pressure gradient and either an assumed or clinically deter...
Ventricular Dysfunction To the Editor: Brookes et al1 reported decreased left ventricular (LV) systolic performance during right ventricular (RV) ischemia in the pig and concluded that “The hemodynamic compromise seen in association with acute RV dilatation within an intact pericardium is partly attributable to impaired LV systolic performance and cannot be wholly ascribed to changes in either ...
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...
OBJECTIVE Abrupt increases in right ventricular afterload occur after cardiac transplantation and pulmonary artery banding, which can result in right ventricular hypertrophy and dilatation. Right ventricular dysfunction is also accompanied by beta-adrenergic receptor desensitization. We sought to determine whether selective right ventricular expression of a transgene encoding a beta-adrenergic ...
Septic shock in humans is usually characterized by a high cardiac output, a low systemic vascular resistance, reversible depression of left ventricular ejection fraction, and transient left ventricular dilatation. The relationship of left ventricular to right ventricular function in septic shock is poorly understood. To evaluate right ventricular vs left ventricular performance and to evaluate ...
introduction: psoriasis is a chronic inflammatory skin disease characterized by plaques covered with silvery scales. psoriasis is highly prevalent in different countries in the world, including iran. several studies have reported a significant association between psoriasis and cardiovascular diseases. this study aimed to evaluate the relationship between psoriasis and cardiac disease using echo...
Background: Aluminum phosphide (known as rice tablet) toxicity is a serious, fatal poisoning despite the advancement of intensive care. Phosphine gas, released after exposure of aluminum phosphide to gastric acidic content, causes mortal systemic toxicity. Multi-organ failure may progress within the first hours of severe toxicity. Refractory hypotension, cardiac shock and metabolic acidosis a...
