As TAVI outcomes have improved over the years, different factors seem to be driving changes in short-term complications and mortality, according to data from the Society of Thoracic Surgeons/American College of Cardiology TVT Registry.

Suzanne V. Arnold, MD (Saint Luke’s Mid America Heart Institute/University of Missouri-Kansas City), who presented an analysis of 30-day and 1-year outcomes for TAVIs performed between 2011 and 2018 in a late-breaking session on Sunday, pointed out that many aspects of TAVI have evolved. The patients themselves became younger and healthier, for instance, while use of femoral access grew, sheath sizes shrank, use of general anesthesia waned, contrast volumes decreased, and new valve designs entered the scene.

"We belive that [our] findings emphasize the importance of device iterations and nondevice procedural factors to improving short-term mortality and complications of TAVR," Arnold said.
