Isolated right ventricular systolic dysfunction in scleroderma.
Scleroderma is a multi-systemic disease of the connective tissue, characterised by inflammatory alterations, occlusive microvascular lesions, and diverse forms of cutaneous and parenchymatous fibrosis. Although its pathogenesis is unsettled, various immune mechanisms have been implicated. Arthralgias, changes in oesophageal motility, spider veins, pulmonary fibrosis, and pulmonary arterial hype...
متن کاملPrognostic importance of right ventricular dysfunction.
When considering the entire range of left ventricular ejection fractions (LVEF) after a myocardial infarction, this parameter is a powerful predictor of mortality. However extended follow up studies have shown that prolonged survival occurs in some patients with congestive heart failure (CHF) who have adverse conventional prognostic markers, including very low LVEF. In patients with LVEF < 20%,...
متن کاملDiastolic And Systolic Right Ventricular Dysfunction Precedes Left Ventricular Dysfunction In Patients Paced From Right Ventricular Apex
BACKGROUND Cardiac dysfunction after right ventricular (RV) apical pacing is well known but its extent, time frame of appearance and individual effect on left ventricular (LV), RV systolic and diastolic parameters has not evaluated in a systematic fashion. METHODS Patients with symptomatic bradycardia and ACC-AHA Class I indication for permanent pacemaker implantation (PPI) were implanted a s...
متن کامل[Acute right atrial and ventricular infarction].
Acute coronary syndromes involving the right side of the heart are associated with increased mortality, a complex clinical course, and lengthy hospitalization, as well as with frequent mechanical and electrical complications. It is important that the signs and symptoms associated with the spread of ischemic disease to the right heart chambers are recognized so that the patient can be given appr...
متن کاملRegional right ventricular dysfunction in acute pulmonary embolism and right ventricular infarction.
BACKGROUND A normally contracting right ventricular apex associated to a severe hypokinesia of the mid-free wall ('McConnell sign') has been considered a distinct echocardiographic pattern of acute pulmonary embolism. OBJECTIVE To evaluate the clinical utility of the 'McConnell sign' in the bedside diagnostic work-up of patients presenting to the Emergency Department with an acute right ventr...
