REVIEW
Ashley Vergis, Krista Hardy
Assessment is an integral component of training and credentialing surgeons for practice. Traditional methods of cognitive and technical appraisal are well established but have clear shortcomings. This review outlines the components of the surgical care assessment model, identifies the deficits of current evaluation techniques, and discusses novel and emerging technologies that attempt to ameliorate this educational void.

REVIEW
Piero Montorsi, Stefano Galli, Paolo M Ravagnani, Marco Roffi
Patients with symptomatic carotid artery disease should be managed by a multidisciplinary team including neurologists, vascular surgeons and interventionalists. Duplex ultrasound is the most widely used diagnostic modality to assess carotid disease, followed by additional imaging tests (CT- or MR-angiography) to confirm the severity of the stenosis, detect brain lesions, and assess intracranial circulation as well as the supra-aortic anatomy. Although overall randomized trial results favored (CEA) over carotid artery stenting (CAS) in symptomatic patients, this was likely related to the insufficient expertise of the endovascular specialists in several of the trials...

OBJECTIVE Recent advances in optics and miniaturization have enabled the development of a growing number of minimally invasive procedures, yet innovative training methods for the use of these techniques remain lacking. Conventional teaching models, including cadavers and physical trainers as well as virtual reality platforms, are often expensive and ineffective. Newly developed 3D printing technologies can recreate patient-specific anatomy, but the stiffness of the materials limits fidelity to real-life surgical situations...

Surgeons routinely perform surgery with noisy, sub-threshold, or obscured visual and haptic feedback, either due to the necessary surgical approach, or because the systems on which they are operating are exceedingly delicate. Technological solutions incorporating haptic feedback augmentation have been proposed to address these difficulties, but the consequences for motor control have not been directly investigated and quantified. In this paper, we present two isometric force generation tasks performed with a hand-held robotic tool that provides in-situ augmentation of force sensation...

Papillary fibroelastomas (PFEs) are the second most common benign neoplasms of the cardiac valves and are being recognized more frequently because of higher resolution imaging technology. PFEs are associated with substantial complications that are secondary to systemic embolism. Surgical resection should be offered to all patients who have symptoms and to asymptomatic patients who have pedunculated lesions or tumors larger than 1 cm in diameter. Herein, we present a patient who presented for a second time in 2 months with stroke symptoms...
