OBJECTIVES In this multicenter, randomized trial we evaluated whether stent implantation after successful recanalization of a chronic coronary occlusion reduced the incidence of restenosis. BACKGROUND Percutaneous transluminal coronary angioplasty (PTCA) in chronic total occlusions is associated with a higher rate of angiographic restenosis and(More)
BACKGROUND Trapidil is an antiplatelet drug with specific platelet-derived growth factor antagonism and antiproliferative effects in the rat and rabbit models after balloon angioplasty. METHODS AND RESULTS The Studio Trapidil versus Aspirin nella Restenosi Coronarica (STARC) is a multicentric, randomized, double-blind trial to assess the effects of(More)
A detailed monitoring, on the basis of single procedures, was undertaken to assess the patient exposure and the occupational doses received by the operators (cardiologist, technician, and nurse) during diagnostic coronary angiography (CAG) and percutaneous transluminal coronary angioplasty (PTCA). The occupational dose to the staff was measured at the(More)
BACKGROUND AND METHODS In a prospective protocol for noninvasive diagnosis of acute cardiac rejection, 83 routine endomyocardial biopsies, followed each time by the analysis of signal-averaged electrocardiography and by a cardiac Doppler echocardiographic study, were performed in 18 heart transplant recipients. The follow-up time was 5 +/- 3.6 months. To(More)
Although stent thrombosis has been greatly reduced by adequate stent expansion with high-pressure balloon inflations and by the use of antiplatelet drugs, this event is still frightening, as it may lead to acute myocardial ischemia resulting in acute myocardial infarction or sudden death. Therefore, the definition of factors associated with stent thrombosis(More)
Restenosis remains the principal drawback of percutaneous transluminal coronary angioplasty (PTCA) since 30-35% of patients still experience it 6 months after the intervention. Several studies have clearly demonstrated that restenosis is a complex multifactorial process that involves smooth muscle cell (SMC) migration and proliferation in the intimal layer(More)
If asked "who needs faster planes?" the vast majority of the 2.75 billion airline passengers (source: IATA 2011) would say that they do need faster planes, and that they need them right now. Still, the commercial aircrafts cruising speed has remained the same -- 800 km/hour -- over the last 50+ years, and after the sad end of the Concorde project, neither(More)
OBJECTIVES The usefulness of transesophageal echocardiography (TEE) in assessing the postoperative results of aortic root replacement (Cabrol's procedure) was evaluated. METHODS Between 1986 and 1993, 31 patients underwent replacement of the aortic valve and ascending aorta by a composite graft using the Cabrol procedure. Twenty-six patients had(More)
