BACKGROUND Adaptive support ventilation (ASV) is a microprocessor-controlled mode of mechanical ventilation that maintains a predefined minute ventilation with an optimal breathing pattern (tidal volume and rate) by automatically adapting inspiratory pressure and ventilator rate to changes in the patient's condition. The aim of the current study was to test(More)
UNLABELLED Adaptive support ventilation (ASV) provides an automatic adaptation of the ventilator settings to patient's passive and active respiratory mechanics. In a randomized controlled study, we evaluated automatic respiratory weaning in ASV for early tracheal extubation after cardiac surgery. Eligible patients were assigned to either an ASV protocol or(More)
Increasing interest is being shown in beating heart (off-pump) coronary artery surgery (OPCAB) because, compared with operations performed with cardiopulmonary bypass, OPCAB surgery may be associated with decreased postoperative morbidity and reduced total costs. Its appears to produce better results than conventional surgery in high-risk patient(More)
BACKGROUND Preparation of the great saphenous vein for coronary artery bypass grafts is traditionally performed through one or many long cutaneous incisions. We describe the dissection of the great saphenous vein through small cutaneous incisions using the Mini Harvest System. METHODS The device is composed of a retractor coupled to a light source.(More)
STUDY OBJECTIVES To study the location, distribution, and intensity of pain in a sample of adult cardiac surgery patients during their postoperative hospital stay. DESIGN In a prospective study, pain location, distribution (number of pain areas per patient), and intensity (0 to 10 numerical rating scale) were documented on the first, second, third, and(More)
Left ventricular ejection fraction (LVEF) is a measure of ventricular function with clinical and prognostic significance and can be reliably calculated with various M-mode and two-dimensional echocardiographic formulas in selected, good quality echocardiograms. Subjective visual echocardiographic estimate of LVEF is a potentially less time consuming and(More)
BACKGROUND Aortoplasty has been advocated for moderate dilatation of the ascending aorta associated with aortic valve disease. We report our results with this conservative approach. METHODS Seventeen consecutive patients with unsupported aortoplasty were reviewed. Twelve patients had aortic valve regurgitation and 5 had stenosis. The aortic wall was(More)
OBJECTIVE Heart manipulation during OPCAB may cause hemodynamical instability in particular for access to the posterior and lateral walls. The 'no compression' technique involves enucleation of the heart without any compression on the cavities, and stabilization of the target area with a suction device. The impact of this technique on hemodynamics is(More)
With advances in heart transplantation, a growing number of recipients are at risk of developing gastrointestinal disease. We reviewed our experience with gastrointestinal disease in 92 patients undergoing 93 heart transplants. All had follow-up, with the median time 4.8 years (range 0.5–9.6 years). During the period of the study we progressively adopted a(More)
