New Study identifies early signs of valve failure one year after TAVI, raising durability concerns in younger patients

“As TAVI is increasingly used in younger and healthier patients, our findings suggest a need to carefully consider valve sizing and long-term durability,” said lead study author Eishan Ashwat, BS, a medical student at the University of Pittsburgh School of Medicine. “Early identification of hemodynamic deterioration may serve as a key predictor of future reintervention and patient outcomes.”

According to the study, patients with 1-year HVD had a five-year aortic valve reintervention rate nearly four times higher than those without HVD (2.3% vs. 0.6%). Prior surgical aortic valve replacement (AVR) was also independently associated with a higher risk of early HVD.

The findings underscore the importance of vigilant long-term follow-up and may influence future decision-making regarding valve selection, particularly in patients with smaller aortic anatomy or a history of AVR.

The study used the updated Valve Academic Research Consortium-3 (VARC-3) definitions to assess bioprosthetic valve function and structural deterioration.
