Randomized Controlled TrialEffects of the heart-lung machine on melatonin metabolism and mood disturbances.
Cardiothoracic surgery using the heart-lung machine (HLM) provokes a pronounced endocrine-metabolic response leading to circadian rhythm disturbances that affect postoperative morbidity. Focus has been laid on changes in melatonin metabolism. The effects of an extra-corporal artificial circulation have not been adequately addressed. ⋯ We found no relevant influence of the HLM on perioperative circadian melatonin profiles. Additionally, no alterations in mood assessment before and after surgery were observed. However, worsening of psychological score was associated with a pronounced disruption of the normal circadian melatonin profile.

Randomized Controlled Trial Comparative StudyEndoscopic vs open saphenous vein harvest for coronary artery bypass grafting: a prospective randomized trial.
Endoscopic saphenous vein harvesting (EVH) for coronary artery bypass grafting (CABG) has been developed to reduce leg wound morbidity and improve patient satisfaction. Choosing between EVH of a short vein segment from the thigh and open venous harvesting (OVH) of a short segment from the calf represents a clinical dilemma as EVH is easiest to perform from the thigh and OVH is easiest to perform from the calf. The purpose of this study was to investigate whether leg wound morbidity was reduced after EVH of a short vein segment from the thigh compared with OVH from the calf. Secondly we investigated whether EVH would reduce length of hospital stay and improve cosmetic results. ⋯ EVH of a short vein segment from the thigh results in less wound morbidity and better cosmetic results compared with OVH of a short vein segment from the calf.

Neuropsychological functioning 3-5 years after coronary artery bypass grafting: does the pump make a difference?
Neurocognitive sequelae after coronary artery bypass grafting (CABG) are frequently reported. The present study investigated the possible difference between on- and off-pump CABG patients in a long-term perspective. ⋯ Three to 5 years after the CABG surgery no difference in neurocognitive deficits is found between on- and off-pump CABG patients, indicating that the extracorporeal circulation (ECC) may not be the main cause of late neuropsychological decline.

Tricuspid valve surgery: a thirty-year assessment of early and late outcome.
Tricuspid valve (TV) surgery is usually performed as a concomitant reconstruction procedure in addition to the correction of other cardiac pathologies. Isolated tricuspid procedures are exceptionally rare. Prosthetic valve replacement is also seldom required. Generally, these patients face a high risk of operative mortality and long-term outcome is poor. In this study we reviewed our experience with TV surgery focusing on risk factors for operative mortality, long-term outcome and incidence of valve related complications. ⋯ Patients who require tricuspid valve surgery constitute a high-risk group. Tricuspid valve repair is associated with better perioperative and long-term outcome than valve replacement. However, patients undergoing replacement showed a significant higher incidence of risk factors for operative mortality. The incidence of re-operation is low with no significant difference when the tricuspid valve has been repaired or replaced. When valve replacement is necessary we recommend the use of a biological prosthesis considering the poor long-term survival.

Clinical TrialIntraoperative cell salvage in infants undergoing elective cardiac surgery: a prospective trial.
For a long time intraoperative cell salvage was considered not to be applicable in paediatric patients due to technical limitations. Recently, new autotransfusion devices with small volume centrifugal bowls and dedicated paediatric systems allow efficient blood salvage in small children. The purpose of this prospective non-randomised study was to determine the impact of intraoperative cell salvage on postoperative allogeneic blood products transfusion in infant patients undergoing cardiac surgery with cardiopulmonary bypass. ⋯ Intraoperative cell salvage, employed as an adjuvant technique to the residual volume salvage in infants undergoing first time cardiac surgery with cardiopulmonary bypass, was a safe and effective method to reduce postoperative allogeneic blood transfusion. Considering current cell salvage related expense and the cost reduction achieved by diminished allogeneic transfusion, intraoperative cell salvage in infants demonstrated no economic benefit.
