Surgical Bailout During TAVR: A Contemporary Analysis of the Centers for Medicare and Medicaid Services Database.

TL;DR

In contemporary data, the annual incidence of TAVR surgical bailout is decreasing, but the short-term mortality remains high, and these data support the need for continued cardiac surgical support in TAVR centers to manage emergent complications.

Key Findings

TAVR surgical bailout occurred in 0.56% of all TAVR procedures in the Medicare population between 2016 and 2024.

  • The study included 400,862 TAVR procedures performed on Medicare beneficiaries between 2016 and 2024.
  • Surgical bailout occurred in 2,240 of these procedures (0.56%).
  • The median follow-up time after TAVR was 952 days (IQR: 414–1,615 days).

The annual incidence of TAVR surgical bailout decreased significantly over the study period.

  • The annual incidence declined from 0.92% (261/28,430) in 2016 to 0.40% (216/54,301) in 2024.
  • This decrease was statistically significant (P < 0.001).
  • The trend reflects improvement in TAVR technique and technology over the contemporary era.

The 30-day mortality rate following TAVR surgical bailout was 26.3%.

  • 588 of 2,240 patients who underwent surgical bailout died within 30 days.
  • This represents a substantially higher short-term mortality compared to patients who did not require surgical bailout.
  • Landmark analysis demonstrated higher mortality of TAVR bailout compared to TAVR without bailout up to 1 year after TAVR (P < 0.001).

Long-term mortality after 1 year was similar between patients who underwent TAVR surgical bailout and those who did not.

  • Landmark analysis showed that mortality after 1 year was similar between the bailout and non-bailout groups (P = 0.53).
  • This suggests that patients who survived the acute bailout period and the first year could expect similar long-term outcomes to those without bailout.
  • The finding implies that patients surviving surgical bailout can achieve durable results.

Hospital surgical aortic valve replacement (SAVR) volume did not significantly affect 30-day mortality following TAVR surgical bailout.

  • 30-day mortality was compared across low-, intermediate-, and high-volume SAVR hospitals using a multilevel hierarchical model.
  • Mortality rates were 27% (102/383) at low-volume, 29% (163/566) at intermediate-volume, and 25% (322/1,291) at high-volume SAVR hospitals.
  • The difference across volume categories was not statistically significant (P = 0.28).
  • This finding was assessed using multivariable analysis to control for confounders.

What This Means

This research analyzed what happens when a heart valve replacement procedure called TAVR (transcatheter aortic valve replacement) goes wrong and requires emergency open-heart surgery to fix — a situation known as 'surgical bailout.' Using Medicare data covering more than 400,000 TAVR procedures performed between 2016 and 2024, the researchers found that this emergency situation is becoming less common over time, dropping from about 1 in 109 procedures in 2016 to about 1 in 250 by 2024. This improvement likely reflects advances in TAVR technology and growing operator experience. Despite becoming rarer, surgical bailout remains extremely dangerous when it does occur. More than 1 in 4 patients (26.3%) who required emergency open-heart surgery during TAVR died within 30 days, and those who survived had a higher risk of death compared to uncomplicated TAVR patients for up to one year afterward. However, among patients who made it past the one-year mark, long-term survival was similar to patients who never needed a bailout. The study also found that the mortality risk during bailout was similar regardless of whether the hospital performed many or few open-heart surgeries per year. This research suggests that all hospitals performing TAVR should maintain immediate access to cardiac surgical teams, since bailout emergencies — though uncommon — carry very high mortality and can occur at any center regardless of its surgical volume. The findings add important evidence to ongoing discussions in the United States about whether TAVR should be allowed at hospitals that do not have cardiac surgery programs on site.
