- Blood conservation during cardiac surgery is critically important because of the inherent risks in homologous blood transfusions. Two techniques for the intraoperative conservation of blood--retransfusion of the red cells using a cell-saver (CS), or retransfusion of the blood using a cardiotomy suction (CTR) system--were compared using biocompatibility markers, granulocyte activation, and production of oxygen-free radicals (OFR). In the CTR group, heparin coated circuits with an uncoated cardiotomy reservoir were used. For the CS group, identical heparin coated cardiopulmonary bypass (CPB) sets, without a cardiotomy reservoir but with a CS, were used. In each group, eight patients had coronary artery bypass grafting performed. The capacity of the whole blood and the granulocytes to produce OFR was estimated by a chemiluminescence, and granulocyte activation was measured as release of the granulocyte granule proteins myeloperoxidase (MPO) and lactoferrin. A significantly reduced capacity to produce OFR by the whole blood was noted at 45 minutes of CPB in the CTR group (68% +/- 17% vs 94% +/- 16% in the CS group). MPO release was higher after 3 hours (p = 0.05) and 20 hours (p < 0.05), postoperatively, in the CTR group (417 +/- 77 micrograms/L and 257 +/- 31 micrograms/L vs 246 +/- 25 micrograms/L and 164 +/- 12 micrograms/L, respectively, in the CS group). We conclude that the heparin coated CPB circuit with the uncoated cardiotomy reservoir may be less biocompatible than the identical CPB set used together with the CS.

- BACKGROUND AND AIM OF THE STUDY: Aortic cannulation during cardiac surgery is a potential etiological factor for perioperative stroke. Cannulae may dislodge aortic-wall calcifications. In addition, the sharp edge of the cannula-tip may shear off vessel-wall tissue, which can be expelled into the lumen. This hypothesis concerning source of emboli was tested in a noncalcified aortic perfusion model. METHODS: Pig aortas were pressurized and cannulated. Washout samples were collected before and after cannulation (n = 40). Particles were deposited onto a 10-microm filter and evaluated by microscopy and digital image analysis. RESULTS: A higher incidence of particles generated by cannulation was noted as compared to before the maneuver (p < 0.001). This increase included small (<0.1 mm, p < 0.001) and intermediate-size particles (0.1-0.5 mm, p < 0.001). Particles above 0.5 mm were few and were not associated with cannulation. CONCLUSIONS: Cannulation was a source of embolic material in the noncalcified aortic model. However, these particles were less than 0.5 mm in diameter and may contribute to neurocognitive decline after cardiac surgery.

- Coronary artery aneurysms (CAA) are rare but potentially fatal pathologies. This case was referred to our Unit after occasional echocardiographic finding of an intracardiac mass. A new detailed transthoracic echocardiogram was decisive for a diagnosis of a large CAA of the right coronary artery, compressing and dislocating the right atrium. Transesophageal echocardiography was not performed because of the data obtained. The diagnosis was confirmed by cardiac catheterization. The patient was managed with a surgical procedure.

- Heart failure has been recognized as a major public health problem. Its incidence and prevalence is increasing and imposes substantial burden on the health care system. Despite much progress in development of many new drugs and innovations in palliative surgical strategy, nontransplant cardiac surgical procedures and the use of mechanical assist devices, pediatric heart transplantation remains the best treatment option for patients with end-stage heart failure. So far, more than 6000 pediatric heart transplantations have been performed worldwide. This article reviews some clinical aspects of pediatric heart transplantation, including the history, indications and contraindications, donor evaluation and recipient management, surgical techniques, risk factors of mortality, and survival of pediatric heart transplantation. The short- and long-term outcomes of pediatric heart transplantation are encouraging. However, the lack of donor hearts still hampers its clinical application.

- Tricuspid and pulmonary valve replacement in patients with advanced carcinoid heart disease (CaHD) reduces right heart failure and improves prognosis. The surgical literature is limited concerning description of technical aspects of valve replacement in CaHD. Although a dedicated multidisciplinary care is required for these frail patients, optimization of surgical technique is important and may lead to better postoperative outcomes.

- BACKGROUND: Randomized trials show high long-term patency for no-touch saphenous vein grafts in coronary artery bypass grafting. The patency rate in off-pump coronary bypass surgery for these grafts has not been investigated. Our center participated in the CORONARY randomized trial, NCT00463294. This is a study aimed to assess the patency of no-touch saphenous veins in on- versus off-pump coronary bypass surgery at five-year follow-up.METHODS: Fifty-six patients were included. Forty of 49 patients, alive at 5 years, participated in this follow-up. There were 21 and 19 patients in the on- and off-pump groups respectively. No-touch saphenous veins were used to bypass all targets and in some cases the left anterior descending artery. Graft patency according to distal anastomosis was evaluated with computed tomography angiography.RESULTS: The five-year patency rate was 123/139 (88.5%). The patency for the no-touch vein grafts was 57/64 (89.1%) in the on-pump versus 37/45 (82.2%) in the off-pump group. All left internal thoracic arteries except for one, 29/30 (96.6%), were patent. All vein grafts used to bypass the left anterior descending and the diagonal arteries were patent 32/32. The lowest patency rate for the saphenous veins was to the right coronary territory, particularly in off-pump surgery (80.0% vs. 62.5% for the on- respective off-pump groups).CONCLUSIONS: Comparable 5-year patency for the no-touch saphenous veins and the left internal thoracic arteries to the left anterior descending territory in both on- and off-pump coronary artery bypass grafting. Graft patency in off-pump CABG is lower to the right coronary artery.

- The risk of poor outcomes is traditionally attributed to biological and physiological processes in cardiac surgery. However, evidence exists that other factors, such as emotional, behavioral, social, and functional, are predictive of poor outcomes. Objectives were to evaluate the predictive value of several emotional, social, functional, and behavioral factors on four outcomes: death within 90 days, prolonged stay in intensive care, prolonged hospital admission, and readmission within 90 days following cardiac surgery.This prospective study included adults undergoing cardiac surgery 2013-2014, including information on register-based socioeconomic factors and self-reported health in a nested subsample. Logistic regression analyses to determine the association and incremental value of each candidate predictor variable were conducted. Multiple regression analyses were used to determine the incremental value of each candidate predictor variable, as well as discrimination and calibration based on the area under the curve (AUC) and Brier score.Of 3217 patients, 3% died, 9% had prolonged intensive care stay, 51% had prolonged hospital admission, and 39% were readmitted to hospital. Patients living alone (odds ratio, 1.19; 95% confidence interval, 1.02-1.38), with lower educational levels (1.27; 1.04-1.54) and low health-related quality of life (1.43; 1.02-2.01) had prolonged hospital admission. Analyses revealed living alone as predictive of prolonged intensive care unit (ICU) stay (Brier, 0.08; AUC, 0.68), death (0.03; 0.71), and prolonged hospital admission (0.24; 0.62).Living alone was found to supplement EuroSCORE in predicting death, prolonged hospital admission, and prolonged ICU stay following cardiac surgery. Low educational level and impaired health-related quality of life were, furthermore, predictive of prolonged hospital admission.

- Objective: For many years, functional tricuspid regurgitation (FTR) was considered negligible after treatment of left-sided heart valve surgery. The aim of the present network meta-analysis is to summarize the results of four approaches to establish the possible gold standard. Methods: A systematic search was performed to identify all publications reporting the outcomes of four approaches for FTR, not tricuspid annuloplasty (no TA), suture annuloplasty (SA), flexible (FRA), rigid rings (RRA). All studies reporting at least one the four endpoints (early and late mortality, early and late moderate or more TFR) were included in a Bayesian network meta-analysis. Results: There were 31 included studies with 9663 patients. Aggregate early mortality was 5.3% no TA, 7.2% SA, 6.6% FRA, and 6.4% RRA; early TR moderate-or-more was 9.6%, 4.8%, 4.6%, and 3.8%; late mortality was 22.5%, 18.2%, 11.9%, and 11.9%; late TR moderate-or-more was 27.9%, 18.3%, 14.3%, and 6.4%. Rigid or semirigid ring annuloplasty was the most effective approach for decreasing the risk of late moderate or more FTR (–85% vs. no TA; –64% vs. SA; –32% vs. FRA). Concerning late mortality, no significant differences were found among different surgical approaches; however, flexible or rigid rings reduced significantly the risk of late mortality (78% and 47%, respectively) compared with not performing TA mortality. No differences were found for early outcomes. Conclusions: Ring annuloplasty seems to offer better late outcomes compare to either suture annuloplasty or not performing TA. In particular rigid or semirigid rings provide more stable FTR across time.

- Abstract Background and Aim of the Study: The aim of this study was to evaluate the impact of pulmonary hypertension (PH) on early and late outcomes following surgery in patients with degenerative mitral regurgitation. Methods: The study included 270 patients who had undergone isolated mitral valve surgery (MVS) for leaflet prolapse during 1998 to 2010. Pulmonary artery systolic pressure (PASP) was measured with Doppler echocardiography pre- and postoperatively. The impact of PH (PASP > 50 mmHg) on mortality and the potential for postoperative resolution of preoperatively elevated PASP was retrospectively analyzed. Results: The incidence of PH was 27% (n = 74/270). Postoperative normalization, or reduction of preoperative PASP, was demonstrated in 87% of the patients with PH at a median of two months (interquartile range 1 to 19). Absent improvement or a postoperative increase in PASP was independently predicted by age (OR 1.08, 95% CI 1.02-1.14, p = 0.010). Preoperative PH resulted in a fourfold higher risk of postoperative mortality (HR 4.3, 95% CI 1.1-17.4, p = 0.039) during the first three years of follow-up. Conclusions: PH is an independent predictor of mortality during the initial three years following MVS. The majority of patients with PH demonstrated a reduction of preoperatively elevated PASP following surgery and the increased risk of mortality gradually decreased after three years. Our findings support early admission for mitral valve surgery before the occurrence of PH. (J Card Surg 2012;27:668-675).

Tidskriftsartikel (refereegranskat)abstract
- BACKGROUND AND AIM: Gastrointestinal complications post cardiac surgery are infrequent but difficult to diagnose and carry a high mortality. Plasma intestinal fatty acid-binding protein (I-FABP) concentrations and the relationship between I-FABP, gastrointestinal dysfunction, and postoperative outcomes were investigated in patients who developed gastrointestinal dysfunction (acute gastrointestinal injury [AGI] grade ≥2) and those with normal gastrointestinal function.METHODS: Patients with (AGI 2 group, n = 11) and without (matched controls, AGI 0 group, n = 22) early postoperative gastrointestinal dysfunction were extracted from a larger single-center prospective observational study, including adults undergoing elective cardiac surgery with extracorporeal circulation, and investigated in this nested case-control analysis.RESULTS: Both groups displayed variations in I-FABP concentrations with higher I-FABP on postoperative Day 1 compared to baseline and postoperative Days 2 and 3 (p < .001 and p = .005, respectively). The AGI 2 group had higher I-FABP concentrations on Day 2 compared to the AGI 0 group (p = .024). I-FABP on Day 2 correlated positively with AGI grade over the first 3 days (p = .036, p = .021 and p = .018, respectively). High I-FABP (defined as fourth quartile concentrations) on Day 1 was associated with more prolonged surgical procedures (p < .05). Furthermore, fourth quartile I-FABP on Day 1 and early gastrointestinal dysfunction were associated with higher frequencies of postoperative organ dysfunction (p < .05) and gastrointestinal complications (p < .05), and higher 365-day mortality.CONCLUSION: The present study indicates an association between intraoperative gastrointestinal injury, postoperative gastrointestinal dysfunction and gastrointestinal complications. A high-powered study is needed to further explore this relationship and the interpretation of I-FABP concentrations in individual cardiac surgery patients.

- Pulmonary artery banding (PAB) remains a crucial technique in modern cardiac surgery. Left lateral thoracotomy, median sternotomy, and left anterior thoracotomy are well-known approaches. With significant scarce reports addressing the application of the upper mini sternotomy approach for PAB, this study aims to share experience and report outcomes of patients operated upon using this approach and its impact on facilitating the redo surgery.Since 2015, we practiced the use upper mini sternotomy approach for PAB in the study center where we conducted this retrospective study of 22 patients who underwent banding through the upper mini sternotomy approach. Indications varied between complete atrioventricular septal defect, multiple muscular ventricular septal defects, and univentricular heart with increased pulmonary blood flow.At the time of PAB, the medians of age 2.0 (1-4.5) months and bodyweight of 3.1 (1.9-4.2) kg were reported against a surgery time range of 75- 135min and peak gradient across the band of 54-78mmHg. There was one unrelated mortality case (4.5%) due to a severe attack of pulmonary hypertensive crisis. Fifteen patients underwent the redo surgery. No mortality or sternotomy-related complications were reported following the second stage surgery while the reopening time ranged between 17 and 32min.The upper mini sternotomy approach for PAB is safe and facilitates the subsequent redo surgery and could be a valuable alternative to other surgical approaches.

- Sepsis-3 Definition Sepsis is defined as life-threatening organ dysfunction due to a dysregulated host response to infection. The clinical criteria of sepsis include organ dysfunction, which is defined as an increase of two points or more on the sequential organ failure assessment (SOFA). For patients with infection, an increase of 2 SOFA points yields an overall mortality rate of 10%. Patients with suspected infection who are likely to have a prolonged intensive care unit (ICU) stay or to have in-hospital mortality can be promptly identified at the bedside with a quick SOFA (qSOFA) score of 2 or higher. Importance The sepsis-3 criteria have emphasized the value of a change of two or more points on the SOFA, introduced the qSOFA, and removed the systemic inflammatory response syndrome (SIRS) criteria from the sepsis definition. Objective To externally validate and assess the discriminatory capacities of an increase in the SOFA score by two or more points, the presence of two or more SIRS criteria, or a qSOFA score of 2 or more points for outcomes in 5109 patients, the vast majority of whom were postcardiac surgery patients who were admitted to a Cardiothoracic Surgical ICU in Singapore. Design, Setting, and Participants A retrospective cohort analysis of 5109 patients with an infection-related primary admission diagnosis in the cardiothoracic intensive care unit (CTICU) at the National University Hospital (NUH) in Singapore from 2010 to 2016. Exposures The SOFA, qSOFA, and SIRS criteria were applied to the data representing the worst condition within 24 hours of ICU admission. Main Outcomes and Measures The primary outcome was in-hospital mortality. Discrimination was assessed using the area under the receiver operating characteristic curve (AUROC). Results In 5109 patients, the average mortality of patients with an increase in the SOFA scores of less than 2 points was 3.5% (n = 64), and it was 6% (n = 199) for those with an increase in the SOFA scores of 2 or more points. The mortality of patients with an increase in the qSOFA scores of less than 2 points was 2.6% (n = 7), and it was 5.3% (n = 256) for those with an increase in the qSOFA scores of 2 or more points. The mortality of patients with an increase in the SIRS criteria of less than 2 points was 3.6% (n = 30), and it was 5.4% (n = 233) for those with an increase in the SIRS criteria of 2 or more points. The AUROC of in-hospital mortality of patients with an increase in the SOFA, qSOFA, and SIRS criteria of 2 or more points was 0.96, 0.95, and 0.95, respectively. Conclusions and Relevance In adults with suspected infection admitted to the CTICU in NUH, the change in in-hospital mortality between patients with an increase in SOFA scores of less than 2 and those with an increase of 2 or more was 2.5 percentage points. In contrast to other studies, the absolute change in mortality was nearly the same compared to the qSOFA and SIRS criteria, and the qSOFA score had the greatest percentage increase of 104%, compared to 71% for the SOFA score and 50% for the SIRS criteria. Besides, from the perspective of discriminatory capacities, an increase in SOFA scores of 2 or more did not demonstrate significantly greater prognostic accuracy for in-hospital mortality than equivalent increases in qSOFA scores or SIRS criteria. These findings suggest distinctive characteristics of the study population in the CTICU that are different from the general population.

- Background: We studied the impact of radical pericardiectomy on early and long-term patient survival, postoperative New York Heart Association (NYHA) functional class, and left ventricular ejection fraction in patients with chronic constrictive pericarditis compared to a sub-total pericardiectomy. Methods: From 1991 to 2016, 41 patients underwent pericardiectomy for chronic constrictive pericarditis. Sub-total pericardiectomy was performed in 17 (41%) and radical pericardiectomy in 24 (59%) patients. Patients in the two study groups had statistically similar NYHA functional class, left ventricular ejection fraction, and cardiac catheterization data. Follow-up was 100% complete with a median time of 4 years. Results: Radical pericardiectomy resulted in increased survival rates at 10 years (94%) compared to sub-total pericardiectomy (55%) (P = 0.014). In the idiopathic chronic constrictive pericarditis sub-group, long-term survival rates were also increased after a radical pericardiectomy (P = 0.001). Eighty-five percent of patients after a radical pericardiectomy were in NYHA functional class I or II after 5 years and 94% up to 25 years versus 53% and 63%, respectively, for the sub-total pericardiectomy group. Conclusions: Radical pericardiectomy provided superior 10-year survival and clinical functional improvement in patients with chronic constrictive pericarditis compared to sub-total pericaridectomy.
