Multicenter Study
Seminal Postoperative Complications and Mode of Death After Pediatric Cardiac Surgical Procedures.
Understanding the seminal complications leading to death after pediatric cardiac surgical procedures may provide opportunities to reduce mortality. This study analyzed all deaths at two pediatric cardiac surgical programs and developed a method to identify the seminal complications and modes of death. ⋯ Seminal complications occurred early postoperatively, and systemic circulatory failure was the most common mode of death. Our classification system is likely scalable for subsequent multicenter analysis to understand cause-specific mortality variation across hospitals and to drive quality improvement.

We report obstruction of an anomalous right coronary artery traversing between the pulmonary artery and aorta after placement of a 21-mm bovine bioprosthesis for critical aortic stenosis requiring emergency revascularization. Although this anomaly has been associated with sudden death syndrome, acute coronary ischemia resulting from aortic valve replacement in patients with anomalous coronary artery has not been sufficiently highlighted in the literature. Awareness of this issue may decrease the risk of this complication in patients with anomalous coronary anatomy undergoing aortic or pulmonary valve replacement. Furthermore, the need for careful preoperative imaging in patients undergoing semilunar valve replacement is essential.

Trocars used during video-assisted thoracic surgery (VATS) present some technical disadvantages due to their rigid structure. We propose the use of an extra-small wound retractor system, designed for general surgery, as alternative to rigid trocar for camera port during VATS. In our experience the wound retractor presents 5 objective advantages: reduces intercostal nerve compression and skin injuries, improves the camera maneuverability, does not displace during operation, and protects the camera by any small parietal bleeding.

Multicenter Study Observational Study
Transcatheter Aortic Valve Implantation Versus Surgical Aortic Valve Replacement for Severe Aortic Stenosis in Patients With Chronic Kidney Disease Stages 3b to 5.
There are scarce data on outcomes after transcatheter aortic valve implantation (TAVI) and surgical aortic valve replacement (SAVR) in patients with renal failure. ⋯ CKD stages 3b to 5 increases the risk of mortality after TAVI and SAVR. In this subset of patients, SAVR was associated with somewhat better early and late survival. The risk of acute kidney injury was higher after SAVR. These findings suggest that CKD stages 3b to 5 does not contraindicate SAVR. Strategies to prevent severe acute kidney injury should be implemented with either SAVR or TAVI.

Heparin is the main anticoagulant used during extracorporeal membrane oxygenation (ECMO) support. Nafamostat mesilate, a synthetic serine protease inhibitor, has seen increased use as a substitute for heparin in patients undergoing ECMO because of its short half-life. We aimed to compare these 2 anticoagulants with respect to bleeding and thromboembolic complications during ECMO support. ⋯ Nafamostat mesilate was found to increase the bleeding risk in patients receiving venoarterial ECMO. Regarding thromboembolic complications, there was no significant difference between heparin and nafamostat. Only old age increased the thromboembolic risk.
