Surgical Transmitral Thrombectomy to Prevent Recurrent Stroke in Acute Myocardial Infarction.

Left ventricular (LV)-thrombi occur in up to 14 % of patients with acute myocardial infarction (AMI) in the era of primary percutaneous coronary intervention. For these patients, anticoagulant therapy (AC) is recommended by AMI-guidelines. When, despite AC, LV-thrombi lead to embolism, surgical thrombectomy is an option, which is not mentioned or not recommended in AMI-guidelines. We report a 46-year old female patient with AMI. An 80 % stenosis of the proximal left anterior descending coronary artery was treated by a drug-eluting stent. Thrombi within the akinetic LV-apex became mobile despite AC and dual antiplatelet therapy, and a cerebellar stroke occurred. By a transmitral surgical approach with endoscopic assistance the thrombi were completely removed. Postoperative course and 12-months follow-up were uneventful. LV-thrombi should be observed carefully regarding changes in morphology. Surgical thrombectomy of LV-thrombi is a rare treatment option to prevent imminent embolism. Benefits versus risks of surgical removal of LV-thrombi need to be carefully weighted.
