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)
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.
Return of blood activated by tissue factor is the main culprit for triggering the coagulation cascade. When this activated blood is diverted from the cardiopulmonary bypass (CPB) circuit, it becomes possible to evaluate the effect of surface treatment on platelet and complement activation. Twenty adult patients undergoing elective coronary artery bypass(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)
The aim of this retrospective study was to evaluate the time-related regression of left ventricular hypertrophy after stentless vs. stented aortic valve replacement. From January 1992 to December 2002, 145 patients had a Toronto stentless porcine valve and 106 had a stented Carpentier-Edwards aortic valve replacement. Over a 10-year follow-up, survival was(More)
Percutaneous vertebroplasty is increasingly used for the treatment of vertebral compression fractures. Local leakage of polymethylmethacrylate cement into the perivertebral space is a common complication, but important systemic effects have rarely been reported. The authors describe the case of a 52-year-old patient with central pulmonary embolism after(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)
We studied the progression of atherosclerotic coronary lesions in 38 patients who had previously undergone angiography and were later hospitalized for an episode of unstable angina pectoris, and in 38 matched patients with stable angina who had also undergone prior catheterization. Patients with unstable angina and those with stable angina were similar in(More)
OBJECTIVE We aimed to analyze trends in drug-eluting stents (DES) use in four international health care and regulatory settings. BACKGROUND Accounts suggest a differential approach to DES internationally and recent reductions in use following reports of late stent thrombosis. Current studies of clinical practice are limited in their scope. METHODS Data(More)
