Percutaneous coronary intervention for three vessels of chronic total occlusion complicated with huge left ventricular thrombus.

A 55-year-old woman with symptoms of heart failure appeared to have ischemic cardiomyopathy complicated with 3-vessel chronic total occlusion (CTO), severely deteriorated left ventricular (LV) function, and large LV thrombus. Because of high risk of surgical thrombectomy in addition to coronary artery bypass grafting surgery, we first confirmed significant reduction of LV thrombus and performed percutaneous coronary intervention against the 3-vessel CTO under preceding anticoagulation therapy with warfarin, aspirin, and clopidogrel. By means of antegrade/retrograde approach, we successfully implanted everolimus-eluting stents one by one, leading to complete revascularization, dramatically improved LV function, and disappearance of LV thrombus without post-procedural embolism.
