Identifying potential predictors of surgical site infection risk following cardiac surgery: a scoping review.

Objectives: This scoping review was undertaken to identify risk predictions models and preoperative predictors of surgical site infection (SSI) in adult cardiac surgery. A particular focus was on the identification of novel predictors that could underpin the future development of a risk prediction model to identify individuals at high-risk of SSI, and therefore guide a national SSI prevention strategy.

Methods: A scoping review to systematically identify and map out existing research evidence on preoperative predictors of SSI was conducted in two stages.

Graft function and incidence of cardiac allograft vasculopathy in donation after circulatory-determined death heart transplant recipients.

Experience in donation after circulatory-determined death (DCD) heart transplantation (HTx) is expanding. There is limited information on the functional outcomes of DCD HTx recipients. We sought to evaluate functional outcomes in our cohort of DCD recipients.

Heart transplantation from an extended criteria donation after circulatory death donor.

Transplantation of donation after circulatory death (DCD) donor hearts is gaining acceptance. However, DCD heart selection has been understandably cautious. We report a case of reconditioning a DCD heart using thoraco-abdominal normothermic regional perfusion in a 46-year-old donor who suffered irreversible brain injury following emergency type-A aortic dissection repair.

Subxiphoid, Nonintubated, Opioid-Free, Video-Assisted Pneumonectomy: A New Frontier in Thoracic Surgery.

Surgical approaches to major pulmonary resections have evolved from thoracotomy to multiportal video-assisted thoracoscopy (VATS) and subsequently uniportal VATS. The efficacy of this progress has been validated in a multitude of publications demonstrating reductions in complications, patient perception of pain, and postoperative length of stay. More recent advances include subxiphoid extrathoracic access and nonintubated, opioid-free anesthesia.

Clinical usefulness, angiographic characteristics, and safety evaluation of intracoronary acetylcholine provocation testing among 921 consecutive white patients with unobstructed coronary arteries.

Background: Coronary spasm can cause myocardial ischemia and angina in patients with and those without obstructive coronary artery disease. However, provocation tests using intracoronary acetylcholine administration are rarely performed in clinical routine in the United States and Europe. Thus, we assessed the clinical usefulness, angiographic characteristics, and safety of intracoronary acetylcholine provocation testing in white patients with unobstructed coronary arteries.

PITX2c is expressed in the adult left atrium, and reducing Pitx2c expression promotes atrial fibrillation inducibility and complex changes in gene expression.

Background: Intergenic variations on chromosome 4q25, close to the PITX2 transcription factor gene, are associated with atrial fibrillation (AF). We therefore tested whether adult hearts express PITX2 and whether variation in expression affects cardiac function.

Methods And Results: mRNA for PITX2 isoform c was expressed in left atria of human and mouse, with levels in right atrium and left and right ventricles being 100-fold lower.
