Abstract:
We report a very rare case of giant left atrial thrombus (size: 7.2 x 4.5 mm(2)) associated with radiofrequency catheter ablation for atrial tachycardia in a 72-year-old man. After 4 weeks of anticoagulation with warfarin, a repeat echocardiogram demonstrated partial resolution of the thrombus (size: 4.5 x 2.6 mm(2)) without systemic embolization.
