Background
To evaluate the safety and efficacy of transcatheter aortic valve implantation (TAVI)
for high-risk patients with aortic stenosis using the J-Valve system.
Methods
30 high-risk patients with severe AS underwent TAVI procedure were enrolled with mean
age 74.5 ± 4.5 years and mean logistic Euro-SCORE-I of 28.4 ± 9.6%. All patients were followed up for 6 months. Outcomes were analysed in accordance
with the updated standardised endpoints defined by the Valve Academic Research Consortium
-2 (VRAC-2) criteria.
Results
VARC-2 defined device success was obtained in 93% (28 of 30 patients). No operative
mortality was noted. No major complications such as third-degree AV-block, myocardium
infraction or cerebrovascular events were noted during procedure and follow-up. Transvalvular
PG was decreased at 6 months compared with preoperative state (PG mean: 55.4 ± 14.9 vs 14.6 ± 6.9 mmHg p < 0.01). No moderate or above degree paravalvular leakage (PVL) was noted. All patients
with successful valve implantation were alive with improved exercise tolerance.
Conclusions
Our initial result has demonstrated that the J-Valve system has the potential to become
a feasible treatment option for high-risk patients with severe AS.
