Safety and Effectiveness of Short-Term Single AntiPlatelet Therapy After Left Atrial Appendage Closure With the LAmbre Device in Patients With Nonvalvular Atrial Fibrillation: A Multinational Real-world Registry
Brief Summary: A prospective, multicenter, single-arm, non-randomized study including consecutive patients with nonvalvular AF(Atrial Fibrillation), with a CHA2DS2-VASc score ≥2 (men) or ≥3 (women), and contraindication for long-term anticoagulant treatment, with successful LAAC (Left Atrial Appendage Closure)procedure with the LAmbre device, who at discharge are eligible for short-term (3-months-only) SAPT. We want to assess if a short-term single antiplatelet therapeutic regime of Acetylsalicylic acid (ASA) 100 mg (or clopidogrel 75 mg if ASA contraindication), once daily, for 3 months is safe and effective at 12 months follow-up.
⁃ All criteria must be met
• Patient 18 years and over and
• Patient with documented nonvalvular AF, defined as AF in the absence of moderate or severe mitral stenosis or a mechanical heart valve and
• Patient with a calculated CHA₂DS₂-VASc score ≥2 (for men) and ≥3 (for women) and
• Patient with a contraindication for long-term anticoagulant treatment and
• Patient who has undergone a successful LAmbre LAAC device implantation with no complications during the in-hospital period after the intervention and
• Patient able and willing to return for required follow-up visits and examinations and
• Patient with Informed consent signed.
