Background The optimal anti-thrombotic treatment after transcatheter aortic valve replacement (TAVR) remains a matter of debate. Dual antiplatelet therapy (DAPT) is recommended but single antiplatelet therapy or oral anticoagulation (OAC) are frequently used according to the patient profile. Whether this may impact clinical outcome is unknown.
Method and objectives: FRANCE-TAVI is a prospective multicenter nation-wide French registry. Our objectives were to identify independent correlates of long-term all-cause mortality and early bioprosthetic valve dysfunction (BVD, defined as increased prosthetic gradient ≥10 mmHg or new gradient ≥20 mmHg).
Results Of 12,804 patients included between January 1, 2013 and December 31, 2015, 11,469 (age 82.8±0.07 years old [mean±SE], logistic Euroscore 17.8±0.1%, mean duration follow-up was 495±3.5 days) were alive at discharge with known antithrombotic treatment and were analyzed for mortality. 2555 had at least 2 echocardiographic evaluations and were eligible of BVD assessment. One third of patients had a history of atrial fibrillation and the same proportion had OAC at discharge (n=3836). Neither aspirin nor clopidogrel were independently associated with mortality. Male gender (adj HR 1.63 [1.44-1.84], p<0.001), history of atrial fibrillation (adj. HR 1.41 [1.23-1.62], p<0.001) and chronic renal failure (adj. HR 1.37 [1.23-1.53], p<0.001) were the strongest independent correlates of mortality. Anticoagulation at discharge (adj. OR 0.54 [0.35-0.82], p=0.005) and a non-femoral approach (adj. OR 0.53 [0.28-1.02], p=0.049) were independently associated with lower rates of BVD, while chronic renal failure (adj. OR 1.46 [1.03-2.08], p=0.034) and prosthesis size ≤23mm (adj. OR 3.43 [2.41-4.89], p<0.001) yielded higher risk of BVD.
Conclusions Gender, renal failure and atrial fibrillation, impacted the most mortality at 3-year follow-up. In contrast anticoagulation (mostly given for atrial fibrillation) decreased the risk of BVD after TAVR.
