Thromboelastography During Rewarming for Management of Pediatric Cardiac Surgery Patients

Lower MA during rewarming is associated with increased risk of perioperative bleeding. In patients with rewarming MA<45mm, intraoperative platelet transfusion may reduce the risk of subsequent bleeding. Individualized platelet transfusion therapy based on rewarming TEG may reduce the risk of bleeding while minimizing unnecessary platelet transfusion.

Same Data, Opposite Results?A Call to Improve Surgical Database Research

Surgical database research is here to stay, and its use will only increase. Decisions made from the time the data set is imported to the final regression model can impact the validity of the findings. A system that questions these steps will pay off with replicable, valid data that are more likely to be accurate and beneficial when informing clinical practice.

Perioperative Circulatory Support for Lung Transplantation

The use of ECMO during lung transplantation seems to reduce postoperative complications and improve short-term outcomes, relative to CPB. However, additional data should be collected through large multicenter randomized controlled trials. Furthermore, preoperative ECMO as a bridge to lung transplantation appears to provide favorable outcomes, although additional data are also needed from experienced transplant centers.

Intra-Operative Autologous Blood Donation for Cardiovascular Surgeries in Japan: A Retrospective Cohort Study

Intra-operative autologous blood donation could reduce the transfusion rate or amount of red blood cells and fresh frozen plasma for patients undergoing index cardiovascular surgery and could be an effective blood transfusion strategy in cardiovascular surgery for Japanese patients.

Comparison of Anticoagulation Strategies in Patients Requiring Venovenous Extracorporeal Membrane Oxygenation: Heparin Versus Bivalirudin

Patients receiving bivalirudin for systemic anticoagulation on venovenous extracorporeal membrane oxygenation experienced a decrease in the number of extracorporeal membrane oxygenation circuit-related thrombotic events as well as a significant decrease in volume of blood products administered.

Hydroxyethyl Starch on Kidney and Haemostatic Function in Cardiac Surgical Patients: Is A Non-Inferiority Study Design Appropriate for This Setting?

In light of the existing concerns on HES use, this study leaves several unanswered questions: how should patients be informed when they are asked to participate in a clinical trial that may randomise them to receive HES? How can a prestigious research group consider it appropriate to adopt a ’non‐inferiority’ study design to evaluate the safety profile of a controversial drug such as HES, when any proven beneficial effects (if there are any) remain unanswered?

Changes in Intraocular Pressure During Coronary Artery Bypass Graft Surgery: An Observational Study

During cardiac surgery regardless of the technique (on-pump CABG, off-pump CABG), intraocular pressures remain in the normal ranges. It should be kept in mind that patients should be avoided from long and extreme Trendelenburg position, low CVP, and MAP levels during cardiac surgery to prevent eye-related complications.

Blood Transfusion Trends by Disease Category in The United States, 2000 to 2014

Blood transfusion rates decreased from 2011 to 2014 in the United States. This decline occurred in most disease categories, which points towards broad strategies like patient blood management systems and disease specific improvements like changes in surgical techniques being effective.

Evaluation, Treatment, and Impact of Neurologic Injury in Adult Patients on Extracorporeal Membrane Oxygenation: a Review

Extracorporeal membrane oxygen (ECMO) is increasingly used as an advanced form of life support for cardiac and respiratory failure. Unfortunately, in infrequent instances, circulatory and/or respiratory recovery is overshadowed by neurologic injury that can occur in patients who require ECMO. As such, knowledge of ECMO and its implications on diagnosis and treatment of neurologic injuries is indispensable for intensivists and neurospecialists.

The International Society for Minimally Invasive Cardiothoracic Surgery Expert Consensus Statement on Transcatheter and Surgical Aortic Valve Replacement in Low- and Intermediate-Risk Patients: A Meta-Analysis of Randomized and Propensity-Matched Studies

In RCTs comparing TAVR and SAVR in low-risk patients, early mortality and stroke were lower in TAVR, but did not differ at 1 year. There was no difference in mortality and stroke in intermediate-risk patients. The Multidisciplinary Heart Team must consider individual patient characteristics and preferences when recommending TAVR or SAVR. The decision must consider the long-term management of each patient’s aortic valve disease.

Malaria and the Heart: JACC State-of-the-Art Review

Although there is a paucity of data regarding cardiac manifestations of malaria, an algorithm for appropriate use of diagnostic tools to assess cardiac involvement has been developed in this paper. Furthermore, it is important to note that typical antimalarial treatment regimens can have fatal cardiac side-effects.

Impact of Single versus Double Clamp Technique on Blood Lactate Levels and Postoperative Complications in Coronary Artery Bypass Surgery

CPB time, cross-clamp time and numbers of proximal saphenous graft and distal anastomosis showed a significant positive correlation with the postoperative lactate level. In the regression analysis, CPB time emerged as the only independent predictor of PHL (OR 1.04, CI 95% 1.01-1.07, P=0.011). There was no difference in postoperative blood lactate levels between SCT and DCT groups.
