ReviewThree-Dimensional Printing and Transesophageal Echocardiographic Imaging of Patient-Specific Mitral Valve Models in a Pulsatile Phantom Model.
Three-dimensional printing is increasingly used in the health care industry. Making patient-specific anatomic task trainers has been one of the more commonly described uses of this technique specifically, allowing surgeons to perform complex procedures on patient-specific models in a nonoperative setting. ⋯ Herein a customized pulsatile left-sided heart model that uses patient-specific 3-dimensional printed valves under physiological intracardiac pressures as a TEE task trainer is described. With this model, dynamic patient-specific valvular anatomy can be visualized with actual TEE machines by trainees to familiarize themselves with the surgery equipment and the imaging protocol.

Review Historical ArticleHistory and Pioneers of Cardiac Anesthesia in Italy.
The first use of extracorporeal circulation in Italy occurred in 1951 in Turin. In the 1960s only 12 heart surgery centers were using extracorporeal circulation to treat patients, and health professionals had to complete their training abroad. ⋯ Many results have been achieved during this period, thanks to the contribution of several pioneers. In this article, the history of Italian cardiac anesthesia and the role of Italian anesthesiologists in the development of this subspecialty in Italy and Europe are reviewed.

Observational StudyType and Size of Implanted Bioprosthetic Valve Rather Than Intraoperative Peak Transprosthetic Valvular Velocity Predict Postoperative Midterm Prosthesis-Patient Mismatch in Patients Undergoing Surgical Aortic Valve Replacement.
High transprosthetic valvular peak velocity (PV) is indicative of prosthesis-patient mismatch (PPM), which exacerbates mortality and morbidity after surgical aortic valve replacement (AVR). During surgical AVR, a high intraoperative PV sometimes is detected, but whether it affects mortality and morbidity is unknown. The aims of this study were to determine whether intraoperative and postoperative PV were correlated and what factors predicted postoperative PPM. ⋯ There was no significant association between intraoperative and postoperative PV values. Implanted valve type and size, but not intraoperative PV, predicted postoperative PPM.

Patient Blood Management for Neonates and Children Undergoing Cardiac Surgery: 2019 NATA Guidelines.
Pediatric cardiac surgery is associated with a substantial risk of bleeding, frequently requiring the administration of allogeneic blood products. Efforts to optimize preoperative hemoglobin, limit blood sampling, improve hemostasis, reduce bleeding, correct coagulopathy, and incorporate blood sparing techniques (including restrictive transfusion practices) are key elements of patient blood management (PBM) programs, and should be applied to the pediatric cardiac surgical population as across other disciplines. Many guidelines for implementation of PBM in adults undergoing cardiac surgery are available, but evidence regarding the implementation of PBM in children is limited to systematic reviews and specific guidelines for the pediatric cardiac population are missing. The objective of the task force from the Network for the Advancement of Patient Blood Management, Haemostasis and Thrombosis (NATA, www.nataonline.com) is to provide evidence-based recommendations regarding anemia management and blood transfusion practices in the perioperative care of neonates and children undergoing cardiac surgery, and to highlight potential areas where additional research is urgently required.
