Key result
TAVI is linked to ~36% reduction in left ventricular mass at 6 months.
Why the study?
Left ventricular remodeling and dysfunction are significant complications of symptomatic degenerative aortic stenosis, prompting an evaluation of the impact of TAVI on LV functional recovery and mass regression.
Does transcatheter aortic valve implantation (TAVI) improve left ventricular functional recovery and induce mass regression in patients with severe symptomatic aortic stenosis?
Observational (n=50)
Does transcatheter aortic valve implantation (TAVI) improve left ventricular functional recovery and induce mass regression in patients with severe symptomatic aortic stenosis?
In patients with severe symptomatic aortic stenosis, TAVI leads to significant left ventricular mass regression, reduced left atrial size, and improved aortic valve hemodynamics at 6 months, though LVEF changes were not statistically significant.

Supports LV mass regression after TAVI; leaves open effects on clinical outcomes and need for randomized confirmation.
Background: Degenerative aortic stenosis (AS) is most common heart valve disease requiring intervention, particularly in aging populations. Left ventricular (LV) remodeling and dysfunction are significant complications associated with symptomatic AS, necessitating effective treatment options like transcatheter aortic valve implantation (TAVI).Aim of the Work: To assess impact of TAVI on LV functional recovery and mass regression in patients with severe aortic stenosis.Patients and Methods: This observational cross-sectional study included 50 patients with severe symptomatic AS who underwent TAVI between. Baseline and 6-month post-procedural echocardiographic parameters, including LV mass, LV mass index, LVEF, left atrial (LA) size, aortic valve area (AVA), and peak aortic velocity, were recorded. Statistical analysis was performed using paired t-tests, and correlation analysis was conducted between preoperative LV mass index and postoperative parameters.Results: Baseline characteristics included a mean body surface area of 1.86 ± 0.17 m², with 74% of patients having hypertension and 98% experiencing dyspnea. Post-TAVI, significant improvements were observed in LV mass (from 300.12 ± 85.24 gm to 193.36 ± 44.71 gm, p < 0.0001) and left atrial size (from 45.64 ± 4.84 mm to 42.56 ± 3.73 mm, p < 0.0001). Peak aortic velocity decreased from 4.35 ± 0.59 cm/s to 1.64 ± 0.45 cm/s (p < 0.0001), while aortic valve area significantly increased (p < 0.0001). LVEF improved post-TAVI but without statistical significance (p = 0.292).Conclusions: It was found that TAVI significantly improved LV function and induced mass regression in patients with severe aortic stenosis.

Teima et al. (2024) conducted an observational in Severe symptomatic aortic stenosis (n=50). Transcatheter aortic valve implantation (TAVI) vs. Pre-procedural baseline was evaluated on Left ventricular mass regression and functional recovery at 6 months (p=<0.0001). TAVI reduced left ventricular mass from 300.12 g to 193.36 g and left atrial size from 45.64 mm to 42.56 mm at 6 months in severe aortic stenosis.
