Retrospective data regarding 290 patients suffering from spontaneous aortic dissection between January 1976 and June 1987 are reported. Dissection was always documented by retrograde aortography and data were collected from 11 catheterization laboratories operating in North-East Italy. The results show that over a 12-year period there was an increase in(More)
Postoperative 24-hour Holter monitoring was performed in 106 patients with atrioventricular septal defect in order to identify the incidence of atrial and ventricular arrhythmias. Of the patients, 72 had separate atrioventricular orifices, including 13 with a small ventricular component to the defect, and 34 patients had a common atrioventricular orifice.(More)
Visceral (intra-abdominal) obesity is associated with a cluster of cardiovascular risk factors that together promote macrovascular and microvascular disease. An atherogenic dyslipidemia, characterized by an increase in serum triglyceride-rich lipoproteins, a decrease in plasma levels of high-density lipoprotein cholesterol and increased prevalence of small,(More)
This research approaches the issues of introducing ICTs (Information and Communication Technologies) into Small and Medium Enterprises, with the aim of finding some conditions that make the organizational context able to manage the change process needed to really get the potential benefits of these technologies. The final objective is to propose a(More)
BACKGROUND Reversibility of pulmonary hypertension in patients affected by mitral stenosis is still under question. METHODS We selected 80 patients (mean age 48 +/- 14) who underwent successful percutaneous mitral valvuloplasty (PMV) for hemodynamic significant mitral stenosis (area < 1.5 cm2) with pulmonary hypertension (mean artery pulmonary(More)
UNLABELLED The frequency of mitral restenosis after surgical commissurotomy has been estimated between 10 and 30% up to 10 years and 85% up to 28 years. Aim of this study was to analyze the results of balloon mitral valvuloplasty (BMV) in a series of patients with previous surgical commissurotomy. METHODS Between December 1988 and December 1995 432(More)
Atrial vectorcardiograms (vcg) were analysed in 23 patients with partial (n = 15) or complete (n = 8) forms of atrioventricular septal defect (AVSD). The rotation and the projection of the maximum left atrial vector (MLAV) on the frontal plane (FP) and on the horizontal plane (HP) were noted. To assess the possible influence of the degree of left-to-right(More)
BACKGROUND Between December 1988 and December 1992, 235 patients (pts) underwent percutaneous balloon mitral valvuloplasty (PBMV). METHODS AND RESULTS There were 55 men (23%) aged 49 +/- 13 years and 180 women (77%) aged 51 +/- 13 years. Previous surgical commissurotomy (PSC) had been performed in 22 pts. Procedure was successful (area > 1.5 cm2 or area(More)
BACKGROUND Free-wall rupture of the heart is the second most common cause of death in acute myocardial infarction (AMI), following pump failure. Acute rupture is more common and rapidly fatal, while subacute rupture, which accounts for about 30% of total cases of mortality in AMI, can be diagnosed early by clinical signs with the support of echocardiography(More)
