“Transparency and outcomes should drive how TAVR is delivered,” commented Ashish Pershad, MD, an interventional cardiologist at Banner-University Medicine Heart Institute in Phoenix who estimated that he performs about 150 TAVR procedures annually. “This is a step forward. I’ve been waiting for this for a long time. Until now, volume has been used as a surrogate outcome, but we know it’s not accurate. I’m confident that this model is a good starting point.” But Dr. Pershad also had concern that this new approach “can lend itself to some degree of gaming,” like a bleeding event getting classified as minor when it was really major, or outlier patients getting dropped from reports.

The temptation to cut corners may be higher for TAVR than it’s been for the cardiac-disease metrics that already get publicly reported, like bypass surgery and myocardial infarction management, because of TAVR’s higher cost and higher profile, Dr. Pershad said. Existing measures “have not been as linked to financial disincentive as TAVR might be” because TAVR reimbursements can run as high as $50,000 per case. “The stakes with TAVR are higher,” he said.
Ultimately, the reliable examination of TAVR outcomes that this new metric allows may lead to a shake-up of TAVR programs, Dr. Pershad predicted. “This is clearly a step toward closing down some programs that [consistently] underperform.”
