* Around 25% of patients required aortic valve replacement within six months, with one-third developing severe symptoms.

* Outcomes in real-world settings may vary, as clinical practice often involves less rigorous monitoring than controlled trials.
* The study exclusively used balloon-expandable valves, limiting its applicability to other valve types.
* Findings primarily apply to low-surgical-risk patients (aged 65 and older) with anatomical suitability for transfemoral TAVR.
* The study cohort consisted predominantly of White individuals, potentially affecting its generalizability to diverse populations.

Early TAVR vs. Clinical Surveillance in Asymptomatic Patients with Severe Aortic Stenosis

In January 2025, a study compared early transcatheter aortic valve replacement (TAVR) with clinical monitoring in asymptomatic patients with severe aortic stenosis[1]. Below is a summary of the salient findings, implications, and limitations of the study:

Findings

  • Patients who underwent early TAVR demonstrated improved left ventricular and atrial function at the two-year follow-up.
  • The TAVR group had a higher probability of favorable outcomes, including survival with stable Kansas City Cardiomyopathy Questionnaire (KCCQ) scores.
  • Early TAVR was more effective in reducing mortality, stroke incidence, and unplanned cardiovascular hospitalizations.

Clinical Surveillance Group

  • Patients experienced a decline in quality of life before transitioning to valve replacement, but significant improvement was observed within 30 days post-procedure.
  • Around 25% of patients required aortic valve replacement within six months, with one-third developing severe symptoms.
  • By the two-year mark, more than 70% of patients in the clinical surveillance group had undergone valve replacement. Disease progression remained unpredictable, leading to declining heart function over time.

Stroke and Mortality Outcomes

  • Mortality rates were similar in both groups, likely due to close monitoring, and were lower compared to previous studies.
  • Stroke incidence was higher in the clinical surveillance group, indicating the need for further research.

Implications and Limitations

  • Outcomes in real-world settings may vary, as clinical practice often involves less rigorous monitoring than controlled trials.
  • The study exclusively used balloon-expandable valves, limiting its applicability to other valve types.
  • Findings primarily apply to low-surgical-risk patients (aged 65 and older) with anatomical suitability for transfemoral TAVR.
  • The study cohort consisted predominantly of White individuals, potentially affecting its generalizability to diverse populations.
  • The COVID-19 pandemic may have influenced some trial outcomes.
