EVEN MILD AORTIC REGURGITATION A RISK FOR MORTALITY AFTER TRANS-CATHETER AORTIC VALVE REPLACEMENT
TCT@ACC-i2: Interventional Cardiology
Background:
Moderate to severe aortic regurgitation (AR) after trans-catheter aortic valve replacement (TAVR) is associated with worse outcomes. The impact of mild AR remains controversial.
Methods:
We evaluated all patients undergoing TF-TAVR at our institution from 2006-2012 (Edwards SAPIEN Valve System, 9000TFX). All procedures were completed by experienced operators with only 1 procedural death. Baseline characteristics and mortality were obtained by chart review. All patients underwent transthoracic echo, interpreted by our echo laboratory, within 30 days of TAVR. AR was quantified by standard guidelines, and further graded on a 0 to 4+ scale.
Results:
Overall, 247 patients were studied at an average age of 80.6 years and 42% were female. Controlling for age, gender, STS score, and baseline ejection fraction (EF), there was a significant increase in mortality for each grade of AR as compared to the complete absence of AR after TAVR (Figure 1). Other variables did not significantly impact mortality.
Conclusion:
Even mild AR after TAVR is independently associated with mortality in a single, large volume center.
