Subsuming the Sense of Touch: From Surgical Robots to Prostheses

Most human tasks requiring dexterous manipulation of objects are highly dependent on haptic feedback. The word haptics is originally derived from Greek and means related to the sense of touch. Despite a big surge of robots in manufacturing in the last couple of decades, most of them still lack haptic feedback. In this talk, I will speak about two applications of robotic technology that subsumes...

3-Year Results of a TAVR Trial in High Surgical Risk Patients.

The PARTNER (Placement of Aortic Transcatheter Valves) trial was first to directly compare TAVR to SAVR head to head in high surgical risk patients. At 1 year, TAVR with the balloon-expandable Edwards Sapien valve (Edwards Lifesciences, Irvine, California) was noninferior for mortality compared with SAVR in this patient cohort (24.2% vs. 26.8%; p 1⁄4 0.001 for noninferiority) (5). This was main...

Role of CMR in TAVR.

Multimodality imaging plays a critical role in planning, performing, and evaluating transcatheter aortic valve replacement (TAVR). Cardiovascular magnetic resonance (CMR) has been underutilized in this patient population to date, but there is increasing evidence that it can offer equivalent or even superior information to more commonly used imaging modalities, such as echocardiography or comput...

TAVR Surgery and Vascular Complications

A recent study by researchers at Penn Medicine shows that incisionless transcathether aortic valve replacement (TAVR) surgery can cut down the length of hospital stay by 30%. It was also shown that there was no impact on post-operative vascular complication rates when compared with conventional transfemoral TAVR, which requires an incision in the groin. The study is published in Circulation: Ca...
