Transcatheter aortic valve implantation using the SAPIEN 3 valve to treat aortic regurgitation: The French multicentre S3AR study - 17/02/23
Highlights |
• | Patients with pure AR on non-calcified valves are contraindicated for surgery. |
• | TAVI could be an interesting alternative to surgery in this setting. |
• | Few data exist on the use of the balloon-expandable SAPIEN 3 THV. |
• | TAVI for pure AR using the SAPIEN 3 THV seems technically feasible. |
• | However, the procedure may be challenging and requires specific precautions. |
Abstract |
Background |
Transcatheter aortic valve implantation now has a major role in the treatment of patients with severe aortic stenosis. However, evidence is scarce on its feasibility and safety to treat patients with pure aortic regurgitation.
Aims |
We sought to evaluate the results of transcatheter aortic valve implantation using the balloon-expandable SAPIEN 3 transcatheter heart valve (Edwards Lifesciences, Irvine, CA, USA) in patients with pure aortic regurgitation on native non-calcified valves.
Methods |
We conducted a retrospective and prospective French multicentre observational study. We included all patients with symptomatic severe pure aortic regurgitation on native non-calcified valves, contraindicated to or at high risk for surgical valve replacement, who underwent transcatheter aortic valve implantation using the SAPIEN 3 transcatheter heart valve.
Results |
A total of 37 patients (male sex, 73%) with a median age of 81years (interquartile range 69–85years) were screened using transthoracic echocardiography and computed tomography and were included at eight French centres. At baseline, 83.8% of patients (n=31) had dyspnoea New York Heart Association class≥III. The device success rate was 94.6% (n=35). At 30days, the all-cause mortality rate was 8.1% (n=3) and valve migration occurred in 10.8% of cases (n=4). Dyspnoea New York Heart Association class≤II was seen in 86.5% of patients (n=32), and all survivors had aortic regurgitation grade≤1. At 1-year follow-up, all-cause mortality was 16.2% (n=6), 89.7% (n=26/29) of survivors were in New York Heart Association class≤II and all had aortic regurgitation grade≤2.
Conclusion |
Transcatheter aortic valve implantation using the SAPIEN 3 transcatheter heart valve seems promising to treat selected high-risk patients with pure aortic regurgitation on non-calcified native valves, contraindicated to surgical aortic valve replacement.
