Assessing the Multiple Dimensions of Engagement to Characterize Learning: A Neurophysiological Perspective

In a recent theoretical synthesis on the concept of engagement, Fredricks, Blumenfeld and Paris1 defined engagement by its multiple dimensions: ...

The advantages of internal thoracic artery skeletonization include early high blood flow, a longer conduit, and less bleeding than pedicle internal thoracic artery grafts. Longer conduits are needed for complete endoscopic arterial revascularization. Therefore this study was designed to determine the feasibility and safety of internal thoracic artery skeletonization using the da Vinci robotic system (Intuitive Surgical, Sunnyvale, CA).

Robotic skeletonizing of the internal thoracic artery: is it safe?

In minimally invasive and robotic mitral valve surgery, a blade retractor is used to elevate the left atrial roof, which often distorts tissue and impairs visualization. We tested the hemodynamic and histologic changes of intra-atrial suction, using a new suction retractor that may improve stabilization and visualization.

Acute effects of suction retraction on atrial hemodynamics and histology.

A substantial barrier to widespread adoption of robotically assisted mitral valve repair surgery is increased operative time compared with that of median sternotomy. Nitinol U-clips (Medtronic, Minneapolis, Minn) made of a shape-memory alloy eliminate intrathoracic suturing and may reduce operative times.

Significant reduction in annuloplasty operative time with the use of nitinol clips in robotically assisted mitral valve repair.

To determine if the time required to perform mitral valve repairs using telemanipulation technology decreases with experience and how that decrease is influenced by patient and procedure variables.
