ReviewHow does successful bridging with ventricular assist device affect cardiac transplantation outcome?
A best evidence topic in cardiac surgery was written according to a structured protocol. The issue was to determine the impact of bridge-to-transplant ventricular assist device support on survival after cardiac transplantation. Altogether 428 papers were found using the reported search, of which 12 represented the best evidence to answer the clinical question. ⋯ In papers reporting a difference in outcome, one year averaged survival was 74% in LVAD recipients compared to 90% in non-bridged patients. Decreased survival is associated with patients suffering from dilated cardiomyopathy, transplanted within two weeks of LVAD implantation and bridged to transplantation before 2003 as opposed to patients transplanted more recently. Based on the available evidence we conclude that in selected patients survival after heart transplantation in patients bridged with VAD is comparable to those who did not receive the device.

Case ReportsMultiple costal cartilage graft reconstruction for the treatment of a full-length laryngotracheal stenosis after an inhalation burn.
After suffering an inhalation burn, a 22-year-old male was intubated for seven days. Full-length massive scar formation in the upper airway necessitated tracheostomy five months later. After this, the stenosis became complete in the cricoid region, and a long cannula was needed to maintain the severely damaged middle-distal trachea. ⋯ The middle portion of the trachea was expanded with a similar graft inserted into the anterior wall below the tracheostomy. The fixing T-tube was removed three months later, and the patient had an adequate airway two years after the last procedure. We conclude that multiple cartilage graft reconstruction can be successful even after the development of an extremely long airway stenosis following inhalation burn injury.

Case ReportsCombined valve-sparing root replacement and total arch replacement with frozen elephant trunk.
We report a case of simultaneous repair of an extensive thoracic aortic aneurysm from the aortic root to the distal aortic arch. A 54-year-old male had annuloaortic ectasia and a transverse aortic and distal arch aneurysm. Aneurysms of the descending aorta and the abdominal aorta were also demonstrated. ⋯ Total arch replacement with the frozen elephant trunk technique is efficacious to exclude distal arch aneurysm or descending aortic aneurysm through median sternotomy. An aortic valve-sparing operation was developed to preserve the native aortic valve function in order to improve the patient's quality of life. We herein report a case of concomitant total arch replacement using a frozen elephant trunk and aortic valve-sparing operation for extensive thoracic aortic aneurysm.

Comparative StudyComparing the outcome of on-pump versus off-pump coronary artery bypass grafting in patients with preoperative atrial fibrillation.
Around 5-15% of patients undergoing coronary artery bypass grafting (CABG) suffer from preoperative/pre-existing atrial fibrillation (PAF). This is a benign arrhythmia but can affect the outcome of the surgery. The aim of this study was to assess the effect of PAF on the immediate postoperative course of patients undergoing on-pump (ONCAB) vs. off-pump (OPCAB) CABG. ⋯ PAF is associated with a higher incidence of postoperative complications. Our results have demonstrated that patients in PAF undergoing ONCAB are more susceptible to the postoperative complications compared to those in SR. However, there were no differences in mid- and long-term outcomes.

ReviewIs preoperative physiotherapy/pulmonary rehabilitation beneficial in lung resection patients?
A best evidence topic in thoracic surgery was written according to a structured protocol. The question addressed was whether preoperative physiotherapy/pulmonary rehabilitation is beneficial for patients undergoing lung resection. Ten papers were identified using the reported search, of which five represented the best evidence to answer the clinical question. ⋯ A prospective randomised controlled study in 1997, showed that two weeks of PRP followed by two months of postoperative rehabilitation produced a better predicted postoperative forced expiratory volume in one second in the study group than in the control group at three months (lobectomy + 570 ml vs. -70 ml; pneumonectomy + 680 ml vs. -110 ml). We conclude that preoperative physiotherapy improves exercise capacity and preserves pulmonary function following surgery. Whether these benefits translate into a reduction in postoperative pulmonary complication is uncertain.
