Angina pectoris results from an imbalance between the oxygen supply and the oxygen needs of the myocardium. While the classic form of angina is usually caused by demands exceeding supply, a primary and transient decrease in coronary blood flow is more and more often recognised as an aetiological factor of myocardial ischaemia. Calcium antagonists, although(More)
A series of 146 consecutive patients who underwent tricuspid valve replacement at the University Brugmann Hospital between 1967 and 1987 was reviewed. Mean age at operation was 51.4 years (+/- 12.1 years). Different types of prostheses were implanted including porcine and bovine pericardial bioprostheses and older and bileaflet mechanical valves. Most(More)
A case of aortobronchial fistula occurring 13 years after coarctation repair by patch aortoplasty is presented. Correct diagnosis was established by computed tomographic scanning and magnetic resonance imaging. Surgical treatment consisted of simple closure of the bronchial defect and interposition of a Dacron graft under partial extracorporeal bypass.
The use of X-rays in cardiac interventional radiology has the potential to induce deterministic radiation effects on the patient's skin. Guidelines published by official organizations encourage the recording of information to evaluate this risk, and the use of reference values in terms of the dose-area product (DAP). Skin dose measurements were made with(More)
One hundred consecutive patients hospitalized in the coronary care unit for unstable angina, excluding patients with Prinzmetal's variant angina, were randomized within 24 hours of admission to treatment with diltiazem (50 patients) or propranolol (50 patients). Also excluded were patients with previous coronary artery bypass surgery and those receiving a(More)
A new coronary artery occlusion was found in 98 of 313 consecutive patients (31%) with coronary artery disease treated medically who underwent catheterization twice, 39 +/- 25 months apart. Multivariate logistic regression displayed 8 independent predictors of new occlusion. Four were available at the time of the second angiogram: the interval between the 2(More)
The introduction of drug-eluting stents (DES) has reduced the occurrence of restenosis in coronary arteries. However, restenosis remains a problem in stented coronary bifurcations. This study investigates and compares three different second generation DESs when being implanted in the curved main branch of a coronary bifurcation with the aim of providing(More)
BACKGROUND Coronary angiography in acute myocardial infarction has revealed complicated atherosclerotic plaque and a high rate of thrombotic occlusion. However, the characteristics of lesions at high risk of subsequent occlusion are not well known. METHODS AND RESULTS In the present study, the qualitative and quantitative angiographic features of 38(More)
In patients treated successfully with primary angioplasty for a first myocardial infarction, the Selvester 32-point score correlates well with infarct size measured with quantitative thallium-201 perfusion imaging. Therefore, it is a useful parameter for infarct sizing, particularly in patients with anterior infarction or reduced ejection fraction at(More)
OBJECTIVE This study investigates the influence of foreign material and blood aspirated from nonvascular structures on activation of coagulation, hemolysis, and blood loss. METHODS The series comprises 3 randomized groups (groups C, S, and S+P) of 10 patients undergoing routine coronary artery bypass grafting with cardiopulmonary bypass. In group C, the(More)
