Our results support a policy of intentionally resecting single-zone N2a NSCLC identified preoperatively as part of a multimodality therapy.

A best evidence topic in cardiac surgery was written according to a structured protocol. The question addressed was whether there was a difference in postoperative outcomes [namely permanent pacemaker (PPM) insertion, rhythm disturbance, reoperation for bleeding, hospital stay and in-hospital mortality] between trans-septal or superior (extended) trans-septal (STS) approaches in comparison with the conventional left atriotomy (LA) used in mitral valve surgery. Using the reported search strategy, 353 papers were found of which 11 represented the best evidence to answer the clinical question. The authors, journal, year and country of publication, patient group studied, study type, relevant outcomes and results of these papers are tabulated. Two papers compared all 3 atrial incisions with neither showing a difference in PPM implantation rate, whereas 2 papers compared just the trans-septal with the LA approach, again both finding no significant difference in PPM implantation. Seven studies compared the STS approach with the LA approach with regard to PPM implantation; 1 study showed that the STS approach was an independent risk factor for PPM implantation, PPM insertion was not necessary in 2 studies and there was no difference in PPM insertion in 4 studies. Postoperative junctional rhythm was studied in 5 papers that compared the STS approach with the LA approach; junctional rhythm was more prevalent in the STS approach in 2 studies, albeit transient, whereas 3 papers did not show a significant difference. Mortality, hospital stay and re-exploration for bleeding did not differ among the 3 groups.

Current evidence suggests risk reduction in 30-day mortality with sutureless AVR versus transcatheter AVR but is inconclusive versus standard AVR in matched patients. Robust randomized evidence is lacking to lend support to any potential recommendation.

Background and aim of the study To determine whether the type of atrial access to the mitral valve (left atriotomy, superior trans‐septal, or limited trans‐septal) influenced postoperative permanent pacemaker implantation and to investigate the effect of the sinoatrial (SA) node artery origin (right coronary or circumflex arteries) on the rate of pacemaker insertion. Methods We retrospectively reviewed consecutive cases of patients who had mitral valve surgery at the Trent Cardiac Centre (2008‐2016). The primary outcome was the incidence of permanent pacemaker insertion. The data were analyzed using univariate then binary multivariate regression analysis. Result Four hundred sixty nine patients had mitral valve surgery. The mean age was 66.5 ± 12.3 years and 47.5% were female. One hundred fifty patients (32%) had mitral valve surgery via the standard left atriotomy approach, while 226 (48.2%) and 93 (19.8%) cases were performed using the limited trans‐septal and superior trans‐septal approaches, respectively. Concomitant tricuspid valve surgery was carried out in 33 cases (7%). The overall rate of pacemaker implantation was 5.3%. On univariate analysis, only age (≥70 years old) and concomitant tricuspid valve surgery were significant predictors of postoperative pacemaker insertion, while on multivariate analysis only age (≥70 years old) remained as a predictor. The type of atrial incision and the origin of the SA node artery did not affect the rate of pacemaker implantation. Conclusion The type of atrial approach to the mitral valve and the origin of the SA node artery did not influence the incidence of postoperative permanent pacemaker insertion.
