Key result

TAVR is associated with no 30-day deaths vs SAVR and better perioperative metrics in lower-risk patients.

  • p=0.029

Why the study?

While TAVR is established for high-risk aortic regurgitation patients, its applicability to low- and intermediate-risk populations remains under investigation.

Does transcatheter aortic valve replacement improve short-term clinical outcomes compared to surgical aortic valve replacement in low- to intermediate-risk patients with aortic regurgitation?

Population

70 low- to intermediate-risk AR patients

Comparison

TAVR vs SAVR with bioprosthetic valves

Design

Single-center retrospective study

Follow-up

30 days

Overview

May support TAVR in low-to-intermediate-risk AR; extends observational evidence but leaves open causality pending RCTs.

Key Points

  • The study aims to compare the efficacy and outcomes of TAVR versus SAVR in low- to intermediate-risk aortic regurgitation patients.
  • Retrospectively analyzed clinical data from 70 aortic regurgitation patients.
  • Included 37 patients who underwent TAVR and 33 who received SAVR.
  • Assessed baseline characteristics, perioperative metrics, and major clinical outcomes.
  • Utilized international registry data for external validity comparisons.
  • TAVR was associated with shorter operation times and reduced blood use.
  • No 30-day mortality was observed in the TAVR group, compared to four deaths in the SAVR group.
  • Conduction abnormalities were more frequent in TAVR patients.
  • Potential cost savings with TAVR were noted in specific scenarios.

TAVR may offer favorable short-term outcomes, including lower 30-day mortality and shorter hospital stays, compared to SAVR in low- to intermediate-risk patients with aortic regurgitation.

Limitations

  • single-center
  • short-term follow-up

Cite This Study

Zhang et al. (2026) studied this question. TAVR resulted in zero 30-day mortality versus four deaths with SAVR (p=0.029) and significantly reduced operation time, blood use, and hospital stays in low- to intermediate-risk patients.
