Cleveland Clinic researchers found that patients undergoing TAVI who have baseline anemia and significant periprocedural hemoglobin drops face higher risks of death and heart failure. The study tracked 1,666 patients who received the procedure between 2016 and 2020.
Why it matters
Identifying anemia before TAVI may help clinicians manage risks, as the research indicates that combined factors like pre-existing low hemoglobin and procedural drops correlate with poor long-term outcomes. Understanding these patterns is essential for patients planning for heart valve interventions.
In a retrospective cohort study of 1,666 patients at the Cleveland Clinic, those with both baseline anemia and a periprocedural hemoglobin decline of at least 2 g/dL faced a 40.9% mortality rate at 3 years. Roughly half of all TAVI patients in the study had baseline anemia.
The players
Cleveland Clinic
An academic medical center that specializes in complex cardiovascular care, including valve replacements and heart disease research.
The details
The study categorized patients by baseline anemia—defined as hemoglobin below 13 g/dL for men and 12 g/dL for women—and the magnitude of their hemoglobin loss during the TAVI procedure. Given that 75% to 90% of anemia cases in these patients are linked to iron deficiency, the drop in hemoglobin post-procedure may complicate recovery in patients whose systems are already taxed by low red blood cell levels. These physiological deficits can leave the heart and body less resilient to the stress of surgery and the subsequent healing phase.
Timeline
Between 2016 and 2020, researchers tracked 1,666 patients treated at the Cleveland Clinic.
Outcomes were measured 3 years post-TAVI for each patient.
The findings were published in the journal Structural Heart in October 2026.
Health Landscape
This research builds on existing efforts within the Cleveland Clinic TAVI research program to optimize patient preparation for transcatheter valve replacement. It highlights a critical need to better manage common comorbidities, such as iron deficiency, to improve long-term survivability.
If you are scheduled for TAVI, it is worth discussing your hemoglobin levels with your cardiologist to see if pre-procedure iron management is appropriate for you. Understanding your baseline anemia status can help you and your physician create a more informed care plan for your recovery.
The takeaway
Anemia is common in TAVI patients, and its combination with procedural hemoglobin loss is linked to significantly higher long-term health risks. Ask your doctor about a complete blood count test before your procedure to identify and potentially address iron deficiency early.
