Multicenter StudyThe Ross operation - a feasible and safe option in the setting of a bicuspid aortic valve?
The Ross operation in the setting of a bicuspid aortic valve (BAV) remains controversial. Using data from the German Ross Registry, we sought to investigate the effect of the presence of a BAV on autograft function and diameters over time after the Ross operation compared with the presence of a tricuspid aortic valve (TAV). ⋯ For the observed time period, postoperative neo-aortic regurgitation after the Ross procedure did not differ between patients with a BAV or a TAV. Root dimensions, although clinically not relevant, increased in both valve entities supporting surgical reinforcement strategies. We cannot consider a BAV as a contraindication for the Ross operation.

Integrated cerebral perfusion for hypothermic circulatory arrest during transverse aortic arch repairs.
Antegrade cerebral perfusion (ACP) during hypothermic circulatory arrest (HCA) for ascending/transverse arch repair is used for cerebral protection. This study evaluates ACP in combination with retrograde cerebral perfusion (RCP) during extended HCA and compares it to RCP-only. ⋯ The observed trends in actual outcomes were a cause for concern. ACP combined with a short period of RCP did not provide better outcomes than RCP-only. The use of RCP remains warranted in our experience.

Clinical TrialPreoperative introduction and maintenance immunosuppression therapy of oral-only tacrolimus, mycophenolate mofetil and steroids reduce acute rejection episodes after lung transplantation.
Immunosuppression therapy in lung transplantation (LTX) remains unsatisfactory due to a high incidence of infection and frequent acute rejection (AR), leading to early onset of the bronchiolitis obliterans syndrome (BOS). The long-term success of LTX is limited by BOS, associated with marked morbidity and mortality. The strongest risk factor for BOS is frequent AR. Decreasing frequent AR episodes might lead to improved long-term survival following LTX. ⋯ Our results suggest that a standard immunosuppressive regimen of TAC and MMF orally administered and introduced prior to skin incision for LTX surgery and maintained long-term might reduce the incidence of acute and chronic rejection. Viral infections and not BOS seemed to be the limiting factor of long-term survival.

Completely thoracoscopic pulmonary vein isolation with ganglionic plexus ablation and left atrial appendage amputation for treatment of atrial fibrillation.
Percutaneous catheter pulmonary vein isolation (PVI) has been the preferred choice for invasive treatment of symptomatic, drug-refractory lone atrial fibrillation (AF). Incomplete ablation lines, procedure-related morbidity and long-term success remain, however, a problem. A minimally invasive surgical approach can provide an attractive and secure alternative. Surgery offers an epicardial, bipolar approach under direct vision, but the invasiveness of surgery remains a problem. Therefore, we developed a completely thoracoscopic procedure. The objective of this study was to assess the feasibility, safety and effectiveness of a completely thoracoscopic surgical procedure to cure lone AF. ⋯ We report our initial experience of a completely thoracoscopic PVI with GP-ablation and amputation of the left atrial appendage and demonstrate that the procedure is feasible, safe and effective for the treatment of lone AF.
