Objective
The study objective was to evaluate the impact of various surgical characteristics and practices on the risk of postoperative atrial fibrillation and other adverse outcomes after cardiac surgery.Methods
By using the prospectively collected data of patients who underwent cardiac surgery in 28 centers across the United States, Italy, and Argentina, the details of surgery characteristics were collected for each patient and the outcomes, including postoperative atrial fibrillation, major adverse cardiovascular events, and mortality. These were evaluated via multivariable-adjusted models.Results
In 1462 patients, a total of 460 cases of postoperative atrial fibrillation, 33 major adverse cardiovascular events, 23 cases of 30-day mortality, and 46 cases of 1-year mortality occurred. We found that type of surgery and cardiopulmonary bypass use predicted the occurrence of postoperative atrial fibrillation. Compared with coronary artery bypass grafting alone, there was a higher risk of postoperative atrial fibrillation with valvular surgery alone (odds ratio, 1.4; 95% confidence interval, 1.1-1.9), and the risk was even higher with concomitant valvular and coronary artery bypass grafting surgery (odds ratio, 1.8; 95% confidence interval, 1.2-2.7). Compared with no bypass, use of cardiopulmonary bypass was associated with higher risk of postoperative atrial fibrillation (odds ratio, 2.4; 95% confidence interval, 1.7-3.5), but there were significant age and sex differences of the impact of bypass use among patients undergoing coronary artery bypass grafting (P for interaction = .04). In addition, compared with spontaneous return of rhythm, ventricular pacing was associated with a higher risk of major adverse cardiovascular events (odds ratio, 5.0; 95% confidence interval, 1.4-18), whereas concomitant coronary artery bypass grafting and valvular surgery was associated with a higher risk of 30-day mortality (hazard ratio, 4.3; 95% confidence interval, 1.2-14) compared with coronary artery bypass grafting alone. Occurrence of postoperative atrial fibrillation was associated with greater length of stay and 1-year mortality (hazard ratio, 2.2; 95% confidence interval, 1.2-3.9).Conclusions
In this multicenter trial, we identified specific adverse outcomes that are associated with concomitant valvular and coronary artery bypass graft surgery, cardiopulmonary bypass, ventricular pacing, and occurrence of postoperative atrial fibrillation. 相似文献8.

Objectives
Open-distal anastomosis is the preferred technique over clamp-on technique for surgical repair of acute type A aortic dissection (ATAAD). The aim of this study was to define how outcomes of ATAAD were affected by the use of either technique.Methods
Nordic Consortium for Acute Type A Aortic Dissection includes 8 academic cardiothoracic hospitals in 4 Nordic countries. The cohort consisted of 1134 patients, 153 clamp-on and 981 open-distal, from 2005 to 2014.Results
Patients who underwent operation with the clamp-on were younger, more frequently had coronary artery disease, bicuspid aortic valve, hypotension/shock or syncope, and a greater PennClass than open-distal patients. Postoperative cerebral vascular accident occurred less frequently in clamp-on (14/153, 10%) compared with the open-distal group (190/981, 20%). Clamp-on had greater 30-day mortality (39/153, 25%) than the open-distal group (158/981, 16%), and 5-year survival was also worse in clamp-on (61.8% ± 4.4%) compared with the open-distal group (73.0% ± 1.6%). The open-distal technique was used more frequently in greater-volume hospitals but was not independently associated with 30-day mortality. Preoperative condition was an independent risk factor whereas hospital volume and later year of operation were beneficial in regard to short-term outcome. Open-distal was independently associated with improved mid-term survival.Conclusions
Patients who underwent operation with the clamp-on were sicker on presentation and had worse short- and mid-term survival compared with the open-distal group. Patients in the open-distal group had greater rates of cerebrovascular complications. The results support the routine use of open-distal anastomosis as the primary operative strategy for ATAAD, although clamp-on can be performed successfully in select cases. 相似文献9.

Background
Tracheal diverticula (TD) are rare anomalies that may harbor infected secretions, posing potential risk to patients with lung disease. In an end-stage cystic fibrosis (CF) cohort, we describe the characteristics and associated post-lung transplant (LTx) outcomes of TD.Methods
Pre-transplant computed tomography (CT)'s were reviewed in CF patients undergoing LTx. TD were characterized radiographically and on autopsy when available. Pre-transplant clinical variables and post-transplant outcomes were compared by TD status.Results
Of 93 patients, 35 (37.6%) had TD. 58% of TD had fat-stranding, and post-mortem TD examinations revealed histology carrying intense submucosal inflammation, and purulent contents that cultured identical species to sputum. There was no difference in post-LTx survival [HR 1.77 (0.82–3.82), p = 0.147], bacterial re-colonization, or rejection in patients with TD compared to those without. Patients with TD were more likely to die from infection, but the result was not statistically significant [HR 2.02 (0.62–6.63), p = 0.245].Conclusions
We found a high prevalence of TD in end-stage CF, where diverticula may represent a large-airway bacterial reservoir. TD were not associated with differences in post-LTx outcomes, but given the infectious concerns further investigation is necessary. 相似文献13.
