Coeliac disease (CD) development involves genetic (HLA-DQ2/DQ8) and environmental factors. Herein, the influence of the HLA-DQ genotype on the gut colonization process of breast-fed children was determined. A cohort of 20 newborns, with at least one first-degree relative with CD, were classified according to their HLA-DQ genotype into high, intermediate and(More)
We present the case of a calcified right coronary artery lesion with a 90-degree exit angle. Attempts at rotational atherectomy led to wire transection and vessel wall perforation necessitating emergent pericardiocentesis and bypass surgery. We review the literature on complications of rotational atherectomy and the management of coronary perforations and(More)
This is the first reported use of the JOSTENT stent graft for aneurysm disease in native coronaries. Consideration can be given to using this polytetrafluoroethylene (PTFE)-covered stent in situations such as dissections and restenosis in saphenous vein grafts or in long native coronary arteries without side branches, though further investigation is(More)
BACKGROUND Reversal of ischemia after myocardial infarction by revascularization is worthwhile only if viability exists in a sufficiently large portion of the left ventricle. METHODS AND RESULTS To determine myocardial hypoperfusion reversibility and its influence on segmental and global function, we studied 50 patients after myocardial infarction. Three(More)
INTRODUCTION Radionuclide ventriculography (RNV) evaluates segmental and global ventricular contractility and also detects conduction abnormalities. OBJECTIVE To assess the temporal parameters of ventricular synchronization in the normal heart by a third harmonic (3H) Fourier phase analysis in a RNV and introduce this technique in our center.

In this randomized, prospective, multicenter trial (n = 661) of patients with de novo or restenotic coronary lesions, 330 patients received the MicroStent(R) II (MSII), and 331 received the Palmaz-Schatz (PS) stent. The short-term procedural success rates were 94.4% and 95.7%, respectively (P = 0.47). The 30-day cumulative incidence of major adverse events(More)
INTRODUCTION AND AIM Gated-SPECT is a promising method to analyze myocardial viability. We have assessed the accuracy of a new protocol of rest/Dobutamine gated-SPECT, based on the evaluation of contractile reserve induced by 10 microg/kg/min of Dobutamine, to predict contractile recovery after revascularization of dysinergic myocardial territories.
