NCT01559298

Brief Summary

The purpose of this study is to compare aspirin + clopidogrel with aspirin alone as antithrombotic treatment following transcatheter aortic valve implantation (TAVI) for the prevention of major ischemic events \[myocardial infarction (MI), ischemic stroke\] or death without increasing the risk of major bleeding events.

Study Arms (2)

Aspirin + clopidogrel

ACTIVE COMPARATOR

Patients will be randomized within the month prior to the TAVI procedure to receive aspirin (80 mg/d) + clopidogrel (75 mg/d) following the TAVI procedure.

Drug: Aspirin (80 mg/d) + clopidogrel (75 mg/d)

Aspirin

ACTIVE COMPARATOR

Patients will be randomized within the month prior to the TAVI procedure to receive aspirin (80 mg/d)

Drug: Aspirin

Interventions

Aspirin (80 mg/d) + clopidogrel (75 mg/d) Aspirin therapy will start at least 24 hrs before the TAVI procedure and continued for at least 6 months. Clopidogrel therapy will start within 24 hrs before the TAVI procedure in cases where a transfemoral approach is used and within 24 hrs after the TAVI procedure in cases where a transapical approach is used. The initial dose of clopidogrel will be of 300 mg followed by 75 mg/die. The duration of clopidogrel treatment will be of 3 months. Patients will be followed either by phone contact or clinical visits at 1- and 12-month follow-up.

Aspirin + clopidogrel

Aspirin (80 mg/d) Aspirin therapy will start at least 24 hrs before the TAVI procedure and continued for at least 6 months.

Aspirin
