This feature length documentary takes an in-depth look at uniportal VATS, the relatively new procedure created by Diego Gonzalez Rivas. The film chronicles the development of the procedure, and follows Dr. Gonzalez Rivas as he introduces the minimally invasive technique to hospitals from the UK to China. Patients who have undergone the uniportal procedure also share their stories.

Propensity score-matched analysis of surgical ligation versus medical management of clinically significant patent ductus arteriosus in premature (<37 weeks), extremely low birth weight infants (<1000 g). Infants undergoing surgical ligation had lower mortality (15% vs 26%) and a higher rate of routine disposition from the hospital (48% vs 41%) as opposed to transferring care or requiring home health services. However, in the surgical ligation group, the length of stay was longer (88.5 days vs 65.6 days) and total cost was higher ($209,829 vs $139,446). Necrotizing enterocolitis and sepsis were independent predictors of mortality in both groups of infants.

This retrospective case-control study involving 1852 Hodgkin lymphoma 5-year survivors found that radiation to the heart valves tend to increase the risk for clinically significant valvular heart disease. The rate increased 3.1-fold in patients receiving 31-35 Gy and 11.8-fold in those who received > 40 Gy.

In this manuscript the authors describe their findings in a meta-analysis of 12 randomized placebo-controlled clinical trials involving 2,980 patients undergoing isolated CABG. They found that statin therapy, particularly atorvastatin, initiated before CABG, was associated with a 58% reduction in the risk of postoperative AF. Unfortunately, the optimal dose of statin therapy to achieve this effect was not addressed in the study. Other interesting findings were that the length of hospital stay was lower, and there was a lower number of strokes with preoperative statin therapy. The risk of postoperative MI and renal failure were not significantly decreased with statins.

The authors analysed 621 reliefs, sculptures and paintings from Ancient Egypt looking for anatomical defects of the chest. They found a relief dated back to 2400 BC, depicting a man with an abnormal shape of the chest similar to a pectus excavatum. The authors opened the debate on the occurrence of this deformity in ancient times.

Westaby and coworkers analyzed the demographic changes of cardiothoracic surgeons in the UK between 1999 and 2014. There was an increase in appointments from overseas and from other European countries which complemented a decrease of UK graduates entering the specialty. Only 5% are females. The authors attribute this to several public discussions in the last years that shed a negative light on cardiothoracic surgery and call to action to restore attractiveness of the specialty.

False-negative results of endobronchial ultrasound-guided transbronchial needle aspiration in non-small-cell lung cancer staging were identified in 14% of 165 patients. Prevalence of false-negative results was low, when three satisfactory samples from mediastinal stations could be obtained and rose, when fewer adequate samples were available. Further, false-negative results were more frequent for left-sided tumors.

Transplantations of hearts from donors >50 years (n=26) were compared to 136 transplantations of hearts from younger donors. Hearts from older donors were preferably transplanted to older recipients, who had also longer waiting times. Short- and long-term survival of both groups was similar, however, there was a tendency to a higher frequency of cardiac allograft vasculopathy in the group that received older hearts.

This concensus statement reviews the unique physiology, insertion techniques, and clinical indications for use of percutaneous mechanical circulatory support devices. As the options for management of different etiologies of heart failure in adult and pediatric populations expand, understanding the advantages of specific devices is vital.
