BACKGROUND Percutaneous coronary revascularization (PCI) has been increasingly applied to unprotected left main trunk (LMT) lesions, with varied long-term success. This study attempts to define the predictors of outcome in this population. METHODS AND RESULTS Two hundred seventy-nine consecutive patients who had LMT PCI at 1 of 25 sites between 1993 and(More)
OBJECTIVE To determine if embolization of pulmonary arteriovenous malformations (PAVMs) decreases the occurrence of migraine. METHODS All 105 patients with hereditary hemorrhagic telangiectasia (HHT), minimum age 16 years, who underwent an embolization of PAVM in our hospital between June 1995 and April 2004, were included in this study. A structured(More)
Plasma concentrations of the third complement component (C3) predict the risk of myocardial infarction. Because chylomicrons stimulate C3 production by adipocytes in vitro, we investigated plasma C3 changes in vivo after an oral fat load. Thirty-seven subjects (20 normolipidemic patients with coronary artery disease [CAD] and 17 healthy control subjects)(More)
Pulmonary arteriovenous malformations (PAVMs) are associated with severe neurological complications in patients with hereditary haemorrhagic telangiectasia (HHT). The objective of the present study was to prospectively establish the diagnostic value of transthoracic contrast echocardiography (TTCE) as a screening technique for PAVM using chest(More)
BACKGROUND Coronary angioplasty frequently creates a thrombogenic surface, with subsequent mural thrombosis that may lead to acute complications and possibly stimulates the development of restenosis. Whether coumarins can prevent these complications is unclear. The objective of this open, randomized trial was to assess the clinical effect of coumarins(More)
BACKGROUND The strategy for treating patients with severe asymptomatic carotid artery stenosis and cardiac disease remains unresolved. Staged or combined carotid endarterectomy in these patients offers the potential benefit of decreased neurological morbidity during and after cardiac surgery; however, in high-risk patients with severe coronary artery(More)
A left atrial myxoma was surgically removed in a 58-year-old man following several embolic events. Five months later, a new myxoma was found in the right ventricular outflow tract and surgically removed. In this patient, we visualized two more recurrences 14 years later, one in the left atrium and the other in the left ventricle. A short review of the(More)
Migraine with aura (MA) is associated with cardiac right-to-left shunt. We prospectively studied the association between pulmonary arteriovenous malformations (PAVMs) and MA in hereditary haemorrhagic telangiectasia (HHT). All 220 consecutive HHT patients who underwent high-resolution chest computed tomography for PAVM screening were included prospectively.(More)

OBJECTIVE An increased hepatic flow of free fatty acids (FFAs) is associated with impaired peripheral FFA trapping by malfunctioning of the complement component 3 (C3)/acylation-stimulating protein system and overproduction of VLDL in familial combined hyperlipidemia (FCHL). Postprandial ketone bodies reflect FFA oxidation in the liver, but the postprandial(More)
Migraine is a common neurological disorder with a great impact on the quality of life and social activities. Pulmonary arteriovenous malformations (PAVMs) are mostly congenital, with a prevalence of 5-50% in patients with hereditary hemorrhagic telangiectasia (HHT). A high prevalence of PAVMs is found in patients with HHT and migraine. Embolization of PAVMs(More)
