Aim of the present study was to record the antithrombotic approach in AF and non-AF patients undergoing TAVI, and to compare the efficiency of the used regimens combination. Antithrombotic approach of patients undergoing TAVI remains a challenging dispute. It becomes even more complex when need for anticoagulant treatment is required due to concurrent atrial fibrillation. Consecutive patients with severe symptomatic aortic stenosis treated with TAVI, were retrospectively studied. All patients were divided into two groups, matched to age, depending on the existence of atrial fibrillation. The primary end-point was the composite of MACE, while the secondary end-point was the occurrence of major bleeding at follow-up. A total of 80 patients were included in the study. Out of them, 20 patients (80.2 ± 5.4 years) suffered from concurrent atrial fibrillation. This group was matched with 20 patients (80.6 ± 3.7 years) with no need for anticoagulation. AF-group patients were treated with clopidogrel plus acenocoumarol for 3 months. Following that, acetylsalicylic acid plus acenocoumarol were prescribed. Non-AF patients were treated with 3 months clopidogrel plus acetylsalicylic acid followed by single acetylsalicylic acid medication. No statistical significant differences in MACE between AF and non-AF group were identified (p = 0.705, phi coefficient = 0.06) (mean follow-up 23.4 ± 14 months). Similarly, there was no statistical significant difference for bleedings among the AF and non-AF patient group (p = 0.658, phi coefficient = 0.14). In patients undergoing TAVI with CoreValve, with concurrent AF, treatment with clopidogrel plus acenocoumarol for 3 months, followed by acetylsalicylic acid plus acenocoumarol, seems safe and effective enough in long-term follow-up.
