Multicenter StudyThe significance of bicuspid aortic valve after surgery for acute type A aortic dissection.
Decision-making concerning the extent of the repair of acute type A aortic dissection (ATAAD) includes functional and anatomical assessment of the aortic valve. We hypothesized that bicuspid aortic valve (BAV) does not impact outcome after surgery for ATAAD. We therefore evaluated the outcome after ATAAD surgery in relation to the presence of BAV, acute aortic regurgitation (AR), and surgical approach, using the Nordic Consortium for Acute Type A Aortic Dissection database. ⋯ Early and mid-term survival did not differ significantly between patients with BAV and TAV.

Comparative StudyResection Process Map: A novel dynamic simulation system for pulmonary resection.
Use of 3-dimensional computed tomography for preoperative and intraoperative simulation has been introduced in the field of thoracic surgery. However, 3-dimensional computed tomography provides only static simulation, which is a significant limitation of surgical simulation. Dynamic simulation, reflecting the intraoperative deformation of the lung, has not been developed. The aim of this study was to develop a novel simulation system that generates dynamic images based on patient-specific computed tomography data. ⋯ We successfully developed a novel dynamic simulation system, the Resection Process Map, for anatomic pulmonary resection.

Right ventricular function and residual mitral regurgitation after left ventricular assist device implantation determines the incidence of right heart failure.
The effect of significant mitral regurgitation (MR) on outcomes after continuous flow left ventricular assist device (cfLVAD) implantation remains unclear. ⋯ After cfLVAD implantation, moderate-severe MR and RVD predicted RV failure. Patients with preoperative moderate-severe MR and TR coupled with moderate-severe RVD might benefit the most from mitral and tricuspid valve intervention.
