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.

Observational StudyIntermittent Cross-Clamp Fibrillation Versus Cardioplegic Arrest During Coronary Surgery in 6,680 Patients: A Contemporary Review of an Historical Technique.
Myocardial management during on-pump coronary artery bypass grafting (CABG) surgery includes aortic cross-clamping followed by fibrillation (XCF) and aortic cross-clamping followed by diastolic cardioplegia (cardioplegia). The authors wished to compare in-hospital and survival outcomes between these procedures. ⋯ This is the largest analysis of XCF. XCF does not adversely affect in-hospital outcomes. Long-term results demonstrate cardioplegic arrest may convey a survival advantage that would preclude routine XCF in the modern era.
