Ghoneim and colleagues retrospectively evaluated surgical risk caused by prior mediastinal radiation therapy (MRT) in patients undergoing aortic valve replacement (AVR). The authors found that operative mortality was higher than predicted when AVR was performed with concomitant procedures, and they speculate this is in part related to the longer cardiopulmonary bypass time required. Despite good short-term outcomes in the isolated AVR group, MRT patients undergoing both isolated and concomitant AVR had reduced midterm survival. The authors suggest this should be considered when weighing the choice of device, the invasiveness of the AVR procedure, and the inclusion of concomitant procedures for this population of patients.

Researchers at Ohio State University in Columbus, Ohio, find that the human heart has multiple pacing mechanisms with redundancies in the sinoatrial node.
Researchers at the CSIR Institute of Genomics and Integrative Biology in New Delhi, India, will soon start a longitudinal study of the factors affecting lung function in children.
Grigor and colleagues investigated the relationship between self-reported patient experience and the incidence of adverse events or prolonged length of hospitalization after surgery. Patients with a prolonged length of stay rated their experience lower on more measures than patients with adverse events did. Notably, extended length of stay was associated with a lower rating of the comprehensiveness of information provided by surgeons.
This retrospective study of the association of BMI to long-term survival after resection of NSCLC identified BMI > 30kg/m2 as an independent predictor of survival. In a propensity score matched set, patients with BMI >30 had better survival than those with a BMI of 25 (p=0.003). The reason for this relationship remains to be elucidated.
This is an excellent summary of progress during the past year in all aspects of lung cancer, from prevention/detection through molecular therapies and future perspectives. Each section is written by a handful of international experts.
Frailty is an important factor in patients undergoing either Transcatheter or Surgical Aortic Valve Replacement. However, it is hard to assess. Multiple scoring systems have been proposed which are either underperforming or are cumbersome to calculate.
In the current study, the authors introduced and tested the Essential Frailty Toolset (EFT), consisting of four items: lower-extremity weakness, cognitive impairment, anemia, and hypoalbumenia. The EFT outperformed other frailty assesment tools in approximatly 1000 elderly patients undergoing either TAVR or SAVR.
Dr. Mack notes in the accompanying editorial that several conclusions can be drawn:
1. Frailty can be assessd using an easy tool
2. Frailty is predictive of 1-year mortality after either TAVR or SAVR
3. EFT improves the power of the STS-PROM to predict 1 year mortality
4. EFT is also predictive for 30-day mortality and 1-year mortality and disability
This important study shows that frailty can classified easily. This facilitates comparitive studies, heart team discussions and clinical decision-making in patients undertoing an invasive treatment for aortic stenosis.
The authors present an extensive experience with the Frozen Elephant Trunk procedure for aortic pathology of varying types. They provide useful tips for each type. The results justify the techniques. The authors also provide some insight into when results may not be so good.
Badhwar and colleagues analyzed the usage and outcomes of surgical ablation (SA) for atrial fibrillation reported in The Society of Thoracic Surgeons database. They found an incrementally increasing volume of SA procedures concomitant with cardiac operations like coronary artery bypass and valve repair/replacement over the 3-year period analyzed. Concomitant SA was associated with reduced risk of mortality and stroke but increased risk of renal failure and subsequent pacemaker implantation.
This research was presented at the 2016 Annual Meeting of the Southern Thoracic Surgical Association, and a brief discussion from that meeting follows the article.

Researchers from Melbourne, Australia, published a study in the NEJM that questions whether new interventions to help premature infants breathe are better for their long-term lung function.
Lacroix and colleagues evaluated pulmonary function, pain, and quality of life in patients who underwent robotic thoracic surgery, predominantly for non-small cell lung cancer. The authors observed no difference between preoperative and 7-month postoperative pulmonary function. Although the majority of patients reported some level of pain at the surgical site, pain was not neuropathic-like and only weakly interfered with daily activities.
