OBJECTIVE Pulmonary hypertension can already be present in patients undergoing cardiac surgery or can be exacerbated by cardiopulmonary bypass. Postoperative treatment is still a challenge for physicians. The aim of this study was to evaluate the effects of inhaled prostacyclin (iPGI2) and nitric oxide (iNO) compared with those of intravenous vasodilators.(More)
The diversity of antibodies in patients with scleroderma, mixed connective tissue disease or “primary” Raynaud's phenomenon could be used as a laboratory aid in the clinical diagnosis. In serum samples of 75 patients we screened for antinuclear antibodies (HEp 2 cells), anti DNA, soluble nucleoprotein and extractable nuclear antigens (Sm, rRNP, Ul-nRNP,(More)
The authors present the cases of two young patients, a man and a woman, who presented with myocardial infarction, in the absence of ischemic heart disease or stenosis of the coronary arteries. The woman was known to have systemic lupus erythematosus (SLE) for the past 3 years (the immunoglobulin M [IgM] anticardiolipins antibodies were positive), without a(More)
BACKGROUND The inflammatory cascade has been hypothesized to be an important mechanism of post-ischaemic myocardial reperfusion injury and several studies demonstrated that C1 esterase inhibitor (C1-INH) is effective in post-ischaemia myocardial protection. Therefore, we aimed to investigate prospectively in a randomised double-blind study the(More)
In 1960 Rabinowitz and Dameshek emphasized the close relationship between idiopathic thrombocytopenic purpura (ITP) and systemic lupus erythematosus (SLE) and suggested that ITP is often a prodrome of SLE. On the basis of tis observation, the present study was designed to investigate the prevalence of SLE in patients with the initial diagnosis of ITP,(More)
OBJECTIVE To evaluate the effects of one year's treatment with beraprost, an orally active prostacyclin analogue, in patients with severe pulmonary hypertension. PATIENTS 13 patients with severe pulmonary hypertension. This was primary in nine, thromboembolic in three, and caused by Eisenmenger syndrome in one. METHODS All patients underwent right heart(More)
The purpose of the study is to evaluate the feasibility and utility of magnetic resonance (MR) image and electroanatomic (EA) maps integration in guiding detailed left ventricle (LV) anatomical and substrate mapping, identifying the most accurate registration strategy. Twenty-five patients with dilated ischemic or non-ischemic cardiomyopathy were enrolled.(More)
Atrial fibrillation (AF) represents one of the most important comorbidities in patients with heart failure (HF). This report highlights the available evidence for the relationship between AF and cardiac resynchronisation therapy (CRT). Studies on the use of CRT in patients with HF and AF have demonstrated its effectiveness. It seems to reduce the AF burden(More)
BACKGROUND The presence of a conduction block at the level of the Koch triangle (KT) and the origin of the multicomponent potentials inside this area are controversial issues. We investigated the propagation of the sinus impulse into the KT and the characteristics of multicomponent potentials recorded in that area in patients with and without(More)
We report a patient with clinical manifestation of arrhythmias and evidence of noncompacted myocardium in both left and right ventricular apex. The diagnosis was made with intracardiac echo performed during the electrophysiologic study. This method has allowed the diagnosis of noncompaction of the ventricular myocardium due to its high resolution. Color(More)
