Left Atrial Closure Clinical Trial
Official title:
Impact of Percutaneous Closure of the Left Atrial on the Maximum Proto-diastolic Speed of the Mitral Ring Measured by Tissue Doppler
The main objective is to demonstrate the equivalence, before and after the percutaneous closure of the left atrial procedure, of the maximum proto-diastolic velocity of the lateral mitral annulus (e 'lat) measured by tissue Doppler. Patients with AF at high embolic risk and presenting a formal and definitive contraindication to anticoagulants having been operated on for percutaneous closure of the left atrial by St Jude AMULET device, considering an equivalence margin of 1 cm / sec.
