PURPOSE OF REVIEW To emphasize the importance and clinical implications of right ventricular function assessment in many situations encountered by intensivists and to explain in practical terms how to perform such an assessment at the bedside. RECENT FINDINGS Assessment of right ventricular function requires a full understanding of the physiology of the right ventricle. The right ventricle, u...

Although both dopamine and dobutamine are potent positive inotropic agents, multiple studies indicate that dopamine may produce a rise in left ventricular (LV) filling pressure, while dobutamine often has the opposite effect. To ascertain the pharmacological and hemodynamic mechanisms responsible for the elevation in LV filling pressure observed with dopamine, we administered incremental infusi...

A 20 year-old male was admitted with a history of recurrent palpitations from 5 years. Baseline ECG revealed premature ventricular contractions (PVCs) delta waves. Stress showed short non-sustained Ventricular tachycardia (VT). Echocardiography moderate dilation the left ventricle mild reduced systolic function and Ejection fraction estimated to be 42%. Right mildly dilated hypokinetic. Both at...

Background and objective: Vascular obstruction and impaired blood flow and oxygen delivery cause a myocardial infarction and limit a personchr('39')s function. Therefore, finding a way to create new arteries and replace blocked arteries has always been of interest to researchers, including exercise physiologists. Therefore, this study was conducted to evaluate the effect of eight weeks of moder...

Background Cocaine use has been associated with cardiomyopathy and ischemic coronary syndromes. However, the pathophysiological mechanisms responsible for these syndromes are not clear and have been suggested to involve direct effects of cocaine on myocyte contractility and coronary resistance as well as indirect effects via altered autonomic tone, secondary mediators, and myocardial metabolism...

Left ventricular (LV) function and hypertro:hy, assessed during cardiac catheterization by quantitative biplane angiocardiography, were re'ated to posteatheterization course in 36 patients found to have cardiomyopathy with depressed eject.on fraction (EF). EF ranged from 0.09 to 0.41, LV mass (M) from 99 to 317 g/m2, LV end-diastolic volume (V) from 104 to 347 ml/m2, and ratio of M/V from 0.66 ...

Introduction: Cardiac magnetic resonance (CMR) derived biventricular global function index (BVGFI) is a new CMR parameter that integrates volumes, mass, and using clinically available parameters. The associations of BVGFI with clinical outcomes in repaired tetralogy Fallot are unknown. Methods: Patients who had before the occurrence composite outcome death, resuscitated sudden or sustained vent...

acute fulminant myocarditis is a life-threatening inflammatory disease of the myocardium characterized by the rapid deterioration of the hemodynamic status of the affected individual. with prompt recognition and appropriate management, complete recovery of ventricular function is likely within a few weeks. we introduce a 28-year-old man with acute fulminant myocarditis, who experienced circulat...

Background Right ventricular (RV) function is important in many disease states, but is difficult to quantify from routine MR imaging. Previous work has shown that long-axis deformation/strain is the most critical contributor to global RV function; however, short-axis datasets allow for better coverage of the RV. Thus it would be ideal to be able to quantify RV long-axis function using shortaxis...
