Implication

Mostly mild paravalvular regurgitation after TAVI often stabilizes or improves by 1 year; leaves open need for longer-term progression data.

Key Points

The study aims to evaluate the occurrence and progression of paravalvular regurgitation in patients after TAVI over one year.
Forty-six patients from a TAVI program were assessed for valve function with aortography and transthoracic echocardiography.
Patients were followed up at one year, with 13 undergoing repeat echocardiography to evaluate regurgitation changes.
The incidence of paravalvular regurgitation immediately post-TAVI was 86%, with 57% having mild and 29% having greater than mild regurgitation.
At one year, the incidence dropped to 77%, with 54% having mild and 34% having greater than mild regurgitation.
In 70% of patients, regurgitation either reduced or remained stable, with no cases of severe regurgitation observed.

Structured PICO

Population

46 patients undergoing transcatheter aortic valve implantation (TAVI) at a single institute. Of the 21 patients who reached 1 year follow-up, median age was 83 (66-91) years and 14 were male.

Intervention

Transcatheter aortic valve implantation (TAVI)

Outcome

Incidence and severity of paravalvular regurgitation at 1 year follow-up assessed by transthoracic echocardiographysurrogate

Paravalvular regurgitation following TAVI is common but predominantly mild, and its severity remains stable or improves in the majority of patients at 1 year.
