OBJECTIVES We sought to determine whether internal mammary artery grafts adapt to an increase in myocardial flow demand and whether they restore maximal flow reserve. BACKGROUND Although mammary grafts are now considered the graft of choice for coronary artery bypass surgery, there is still controversy about whether they can provide adequate flow at(More)
AIMS The Stent Thrombosis In Belgium (STIB) trial aimed to determine whether assessing platelet reactivity (PR) in patients with stable coronary artery disease undergoing elective percutaneous coronary intervention (PCI) could predict the risk of ischaemic complications and adverse clinical events up to 30 days post PCI. METHODS AND RESULTS PR before(More)
BACKGROUND Lesions in small-diameter vessels (<3 mm) define a group with distinct clinical and morphological characteristics. There is an inverse relationship between vessel size and angiographic restenosis rate. This study assessed whether stents reduce angiographic restenosis in small coronary arteries compared with standard balloon angioplasty. METHODS(More)
Between December 1988 and September 1993, 157 patients (141 men, 16 women, average age 60.2 years, range 37 to 78 years) underwent a complete myocardial revascularization with 157 inferior epigastric artery grafts and 285 internal mammary artery grafts (281 in situ, 4 free grafts). A total of 543 distal arterial anastomoses (average 3.4, range two to five(More)
Retroaortic crossing of the pedicled right internal thoracic artery for revascularization of the circumflex artery used in combination with a pedicled left internal thoracic artery anastomosed to the left anterior descending artery and its branches is an attractive technique to achieve an extensive arterial revascularization of the left ventricle. However,(More)
BACKGROUND CK-MB levels exceeding 3 times the upper limit of normal (ULN) following percutaneous coronary intervention (PCI), defining periprocedural myocardial infarction (PMI), are associated with worse outcomes. This study assessed the incidence and mechanisms of PMI and their impact on in-hospital stay. METHODS AND RESULTS Over a 12-year period(More)
AIMS Despite a proven safety profile, the transradial approach (TRA) for coronary procedures is regarded by many as complicated and the second-choice arterial access, with a high conversion rate to transfemoral access (TFA). This study reports causes of failure and the contemporary success rate of TRA when both radial arteries are attempted first before(More)
Between December 1988 and April 1991, 74 free inferior epigastric arteries were used in 73 patients for coronary artery bypass grafts. In addition, 72 of the patients received a left internal mammary artery for single or sequential grafting to the left anterior descending system and 62 a right internal mammary artery to the circumflex or the right coronary(More)
A noninvasive method to assess left internal mammary artery (LIMA) patency and function would be useful because this vessel is frequently used for revascularization of the left anterior descending coronary artery. The purpose of this study was to assess the feasibility of measuring changes in LIMA velocities by transcutaneous Doppler during(More)
