What are the alternatives to anticoagulation in an individual with an atrial thrombus and absolute contraindications to anticoagulation?

This is not an easily answered question in this sort of a forum. This clinical situation requires multidisciplinary input and individualized approach. Factors to consider include but not limited to, 1) estimated risk of systemic arterial embolism (note, current tools/calculators provide the annual risk of systemic embolism and not necessarily the short term risk), 2) underlying reason for contraindication to anticoagulation, 3) is the contraindication temporary (reversible) vs permanent, and 4) coexisting thrombophilias.
