Korte et al. studied the results of a surgical exposure and assessment program for cardiac surgery residents and fellows. The program constitutes simulator training, self-organized trainings, and instructed workshops, and was evaluated within students, residents, and fellows. This concept could facilitate structured learning success and evaluation in the training for cardiac surgery.
Using wearable technology, Meltzer et al. demonstrated that surgeon-reported risk factors for pain included longer case length, increased years in pratice, use of loupes, and use of headlights. Further research is needed in order to improve surgeon ergonomics, especially around cardio-thoracic surgeons, who routinely wear loupes, headlights, and have some of the longest case lenghts.
Bavaria et al reported the five-year outcomes of thoracic endovascular aortic repair (TEVAR) of complicated acute type B aortic dissection (TBAD) in the DISSECTION trial. In this prospective, nonrandomized study, 50 patients were treated with the Valiant Captivia thoracic stent graft for acute complicated TBAD. Prior to TEVAR, malperfusion was seen in 86% (43/50), ruptures in 20% (10/50), and DeBakey class IIIb dissections in 94% (46/49).
At five years, clinical and imaging follow-up was available in 78% (18/23); freedom from dissection-related mortality, secondary procedures related to dissection, and endoleak were 83%, 86%, and 85%, respectively; complete thrombosis of false lumen across the stented aortic segment was seen in 89% (16/18); true lumen diameter across the stent graft was stable or increased in 94% (16/17); and false lumen diameter was stable or decreased in 77% (13/17) of patients.
These results show that patients with complicated TBAD experienced positive and sustained measures of aortic remodeling after TEVAR and the Valiant Captivia thoracic stent graft system was effective in the long-term management of acute complicated type B aortic dissections in this challenging patient population.
This article by Zhao et al. analyzes the risk of stroke in patients suffering from type A dissection depending on preoperative CT findings. They identified aortic regurgitation, dissection of the common carotid artery, and the ratio of the true lumen to the diameter of the involved ascending aorta as independent risk factors.
A medium-sized RCT from the Imperial College. The research question are of interest for all cardiovascular, thoracic, and general surgeons as well as all healthcare professionals.
Surgeon ergonomics is an underappreciated occupational hazard. This study uses inertial measurement units to monitor ergonomics of surgeons, including a small handful of cardiac surgeons. More research and discussion is needed in the this space.
Interesting hypothesis in a rodent model of myxomatous degeneration.
This original article compares the outcome of sleeve lobectomy compared to conventional lobectomy in the treatment of patients with lung cancer. Inci et al. investigated 187 patients who underwent sleeve lobectomy and compared it to 568 patients who underwent conventional lobectomy. They found no difference in safety end-points or mid-term follow-up regarding the two different groups.
