Multi-slice computed tomography technology is emerging as a realistic investigation in patients with suspected disease in native, stented or grafted coronary arteries. A non-invasive diagnostic tool is desirable as these patients are at high risk for complications of invasive angiography. A 64-slice CT may achieve the desired diagnostic accuracy, and ...

Coronary artery bypass grafting has had a significant impact on the treatment of angina, and has been the 'gold standard' since 1969. Its use and efficacy has been increased by revascularization in cardiac arrest and the use of the internal mammary artery. In parallel, catheter techniques have evolved by means ...

BACKGROUND: In multiple bypass surgery, when the ascending aorta cannot be used as an inflow, it is sometimes necessary to use an abdominal artery. This technique is useful when a re-median sternotomy might damage a patent graft in patients undergoing reoperations or when the gastroepiploic artery is unsuitable for use ...

Paroxysmal nocturnal haemoglobinuria (PNH) is a rare acquired haemolytic anaemia. Cardiac bypass surgery in patients with PNH may be complicated by aggravation of haemolysis in addition to increased risk of infection, renal failure, bleeding and thrombosis. We describe a case of uncomplicated cardiopulmonary bypass surgery for aortic valve replacement and ...

Two patients underwent combined heart and lung surgery performed through a limited left anterior thoracotomy. Good exposure of the left pulmonary hilum and the left anterior descending artery was obtained, allowing left upper lobectomy combined with off-pump coronary bypass grafting. This approach avoids potential complications due to sternotomy, staged operations, ...

The introduction of percutaneous coronary interventions (PCI) with stent implant has substantially shifted the treatment of coronary artery disease. The current approach to coronary artery disease treatment includes first-choice PCI in selected subgroups; and once this therapy fails, frequently the patient is referred for coronary artery bypass graft surgery. However, ...

Coronary artery bypass is one of the most expensive operative procedures in the US. Considerable cost variation exists among hospitals across the country, and considerable variation in supply cost exists among surgeons. Implementation of "Best Practice Model" can reduce variable cost as much as $1300 per patient. Cost reduction is ...

OBJECTIVES: To investigate the influence of cardiopulmonary bypass on pulmonary hemodynamics and gas exchange. METHODS: Low risk patients admitted for elective coronary artery bypass grafting were randomized to either on (n=25) or off pump (n=25) surgery. Central hemodynamics, gas exchange, and venous admixture were studied during and up to 20 ...

Ascending aortic dissection is a known complication of cardiac surgery. Off-pump coronary artery bypass surgery seems to be associated with a higher risk for this event as compared with on-pump bypass surgery. This increased risk may result from aortic side-clamping under pulsatile flow as opposed to continuous flow in conventional ...

Off-pump coronary artery bypass surgery has been adopted enthusiastically worldwide. However, despite more than 6 years' experience and refinement, many surgeons use it only sporadically and some hardly at all. This reluctance persists despite support for the procedure because of the lack of properly designed risk models and/or randomized studies. ...
