- Although left ventricular free wall rupture is a comparatively common cause of death in acute myocardial infarction survival is infrequently reported. However, even in cases where surgical expertise is not immediately available the condition can be temporarily controlled by judicious pericardial aspiration and blood transfusion until definitive repair can be undertaken. Here we report the successful management of a patient sustaining combined left ventricular free wall rupture and ventricular septal rupture in a community hospital 130 km from the referral center.

- To describe monitoring of a cardio-thoracic department from a total quality aspect point of view and to follow the development over 9 years. During the time period 1994-2002 a total of 10,828 cardio-thoracic operations were performed. Capacity, demographic, risk, quality, outcome and economic data were prospectively collected in various registries and analysed. Mean (and median) age increased from 64.2 to 65.3 (66-67). Patients above 70 years increased from 33.6 to 38.7% and above 80 from 2.9 to 5.5%. Operative mortality was unchanged over the time periods at slightly over 2%, with 1-year mortality 6-7%. Mortality for primary, elective coronary artery bypass grafting was 0.26% during the last 3 years. The rate of postoperative complications remained unchanged or decreased with few exceptions: Patients with postoperative confusion increased from 5.0 to 8.1% and patients with a need for face mask ventilation increased from 2.4 to 4.0%. Mean postoperative ventilation time was unchanged at around 22 h, whereas the median decreased from 9.5 to 5.3 h. The workload created by elderly patients was especially noticeable in the intensive care unit (ICU) as both number of postoperative deviations and ICU hours increased as a function of age. Cost per operation decreased by 11%. Total medical rationalisation was higher as salaries increased over time. Mean length of stay decreased by 3 days. Hospital staff hours per operation decreased whereas hospital staff hours per patient hour increased. Physician cost per operation was unchanged. Patient, staff and referring physician satisfaction was high. Several areas for improvement have been found. Monitoring and general feedback of total quality factors has shown itself a powerful tool to detect and follow large and subtle changes in the practice of cardio-thoracic surgery. Most followed factors show improvement in spite of an increase in mean and median age. Several areas may be defined where further development might decrease the trauma to the patient. Aiming at a total quality and patient safety system, monitoring is an essential prerequisite.

- Objective: Adenosine as an additive in blood cardioplegia is cardioprotective in animal studies, but its clinical role in myocardial protection remains controversial. The aim of this study was to investigate whether the addition of adenosine in continuous cold blood cardioplegia would enhance myocardial protection.Methods: In a prospective double-blind study comparing adenosine 400 μmol l(-1) to placebo in continuous cold blood cardioplegia, 80 patients undergoing isolated aortic valve replacement were randomized into four groups: antegrade cardioplegia with adenosine (n = 19), antegrade cardioplegia with placebo (n = 21), retrograde cardioplegia with adenosine (n = 21) and retrograde cardioplegia with placebo (n = 19). Myocardial arteriovenous differences in oxygen and lactate were measured before, during and after aortic occlusion. Myocardial concentrations of adenine nucleotides and lactate were determined from left ventricular biopsies obtained before aortic occlusion, after bolus cardioplegia, at 60 min of aortic occlusion and at 20 min after aortic occlusion. Plasma creatine kinase (CK-MB) and troponin T were measured at 1, 3, 6, 9, 12 and 24 h after aortic occlusion. Haemodynamic profiles were obtained before surgery and 1, 8 and 24 h after cardiopulmonary bypass. Repeated-measures analysis of variance was used for significance testing.Results: Adenosine had no effects on myocardial metabolism of oxygen, lactate and adenine nucleotides, postoperative enzyme release or haemodynamic performance. When compared with the antegrade groups, the retrograde groups showed higher myocardial oxygen uptake (17.3 ± 11.4 versus 2.5 ± 3.6 ml l(-1) at 60 min of aortic occlusion, P < 0.001) and lactate accumulation (43.1 ± 20.7 versus 36.3 ± 23.0 µmol g(-1) at 60 min of aortic occlusion, P = 0.052) in the myocardium during aortic occlusion, and lower postoperative left ventricular stroke work index (27.2 ± 8.4 versus 30.1 ± 7.9 g m m(-2), P = 0.034).Conclusions: Adenosine 400 μmol l(-1) in cold blood cardioplegia showed no cardioprotective effects on the parameters studied. Myocardial ischaemia was more pronounced in patients receiving retrograde cardioplegia.

- Minimally invasive ablation of atrial fibrillation is an option in patients not suitable for or refractory to catheter ablation. Total endoscopic ablation can be performed via a monolateral approach, whereby a left atrial box lesion is created. If the ablation is introduced from the right side, the positioning of the ablation catheter on the partly hidden left pulmonary veins is of vital importance. Using thoracoscopy in combination with multiplane transoesophageal echocardiography, the anatomical position of the ablation catheter can be established. Our experience in over 60 procedures has confirmed this to be a safe technique of total endoscopic ablation.

- In the Cox-Maze IV procedure, or in endocardial left atrial ablation, correct positioning of the surgical ablation probe within the left atrium might be difficult due to bulging or folds in the posterior left atrial wall. The Berglin apical stitch is a simple trick of the trade to create a smooth surface in the posterior left atrium that facilitates performing a safe transmural lesion and, consequently, may increase antiarrhythmic efficiency.

- Gastrointestinal (GI) complications are serious consequences of cardiac surgery. The aim of this study was to develop, evaluate and validate a new risk score model for GI complications after cardiac surgery. The risk score model, named gastrointestinal complication score (GICS), was developed using prospectively collected data from 5593 patients who underwent 5636 cardiac surgical procedures between 1996 and 2001. The model was validated on 1031 cardiac surgery patients between 2005 and 2006. The scoring system's ability to predict GI complications was estimated by receiver operating characteristic (ROC)-curves and Hosmer-Lemeshow test. Fifty GI complications were identified in 47 patients (0.8%) in the developmental data set and eight (0.8%) in the validation data set. The ROC area in the developmental data set was 0.81 with a good calibration estimated by Hosmer-Lemeshow test (p=0.89). In the validation data set, the area under the curve was 0.83. The estimated probability for the patient to develop a GI complication after cardiac surgery at a GICS >/=15 is >20% and at a GICS

- Surgical approach with reduction pulmonary artery plasty and valved conduit in patients with respiratory compromise prior to repair is associated with excellent long-term survival at the cost of a higher reintervention rate. OBJECTIVES: Absent pulmonary valve syndrome is a rare congenital heart defect with pulmonary artery dilatation and secondary airway compression. Although preoperative respiratory support and early surgical repair with pulmonary arterioplasty are often required in patients with airway compromise, the need for extensive plasty in these patients and for plasty in general in those with no or mild respiratory issues remains debatable. METHODS: We performed a retrospective survey of patients with this diagnosis and repair from 1988 to 2018. RESULTS: Twenty patients were identified. The median age and weight at repair were 0.8 (0.1-2.4) years and 7.0 (2.5-13.8) kg and included a valved conduit in 17 (85%) patients and a transannular patch in 3 patients. Five (29%) patients were ventilator-dependent prior to repair at the age of 0.3 (0.1-0.4) years. Pulmonary arterioplasty was performed in 7 patients (35%), including all 5 with ventilator dependency and 2 with respiratory symptoms due to recurrent infections. Two patients (10%) with preoperative ventilator dependency underwent extensive intrahilar arterioplasty. Preoperative ventilator dependency was associated with earlier repair and reinterventions (P < 0.05). There were 3 late deaths among cases with repair after 2000 (n = 14), none with preoperative ventilator dependency. CONCLUSIONS: The long-term outcomes of patients with this rare defect are good, comparable to those of other previous studies. Reduction pulmonary arterioplasty, which in this study was used only in patients with respiratory distress and ventilator dependency, is associated with excellent survival. Reinterventions are common in these patients.
