NINO-PULIDO, César D. et al. Left atrial appendage closure in a patient with prior atrial septal defect occlusion. Rev. Colomb. Cardiol. [online]. 2022, vol.29, n.2, pp.244-247.  Epub May 19, 2022. ISSN 0120-5633.  https://doi.org/10.24875/rccar.m22000142.

Atrial fibrillation is the most prevalent arrythmia in clinical practice, associated with a significant morbimortality explained, in part, by the high risk of embolic phenomena. The use of anticoagulation is the standard of care in those patients with increased embolic risk (given by a score ≥ 2 in the CHA2DS2Vasc scale). However, some patients have contraindications to receiving this treatment long-term, in which case percutaneous left atrial appendage occlusion can be considered as a means of decreasing their embolic risk. Because the procedure requires transeptal puncture, the presence of devices for atrial septal defect closure can difficult the technique. We present the case of a patient with absolute contraindication to anticoagulation therapy given gastrointestinal bleeding, with history of percutaneous closure of interauricular communication, who was treated with percutaneous left atrial appendage occlusion as an alternative to oral anticoagulants.
