Abstract
Background
Left ventricular (LV) thrombus is a lethal complication of coronary artery disease that can lead to embolization and sudden death. There is no clear consensus on the optimal treatment for LV thrombi. There is a paucity of case series about surgical excision of LV thrombus in patients with coronary vessel disease. For that, there is insufficient evidence to support surgical excision of LV thrombus and recommend the optimal timing of this procedure.
Case summary
We report a case of a 52-year-old man with a history of percutaneous catheter intervention for mid-right coronary artery lesion 3 years ago. He presented with two-vessel coronary artery disease with three LV thrombi. The thrombi were mobile and protuberant. We performed coronary artery bypass grafting in both vessels and LV thrombectomy with video-assisted cardioscopy.
Discussion
Mobile or protuberant thrombus is the most important risk factor for embolization of LV thrombus. On the other hand, LV thrombus size rarely appears in studies as a risk factor for embolization, and when it does, it is a lesser risk factor. There are no case reports describing simultaneous formation of three LV thrombi after myocardial infarction, and it is not known if the risk of embolism is high in such cases. Our patient had very fragile thrombi, and thrombectomy was performed along with coronary artery bypass grafting due to the high risk of embolism.
