Successful trapping of an organized thrombus in a coronary artery aneurysm in myocardial infarction: case report and literature review

Three-vessel coronary artery aneurysmal disease complicated by multivessel thrombosis and cardiogenic shock: the saving role of intracoronary thrombolysis

The benefit of intracoronary thrombolytics in ST-elevation myocardial infarction (STEMI) is not well established. Mainstays of STEMI management include intravenous thrombolytics, percutaneous coronary interventions and surgical revascularisation. However, in cases of STEMI secondary to coronary artery aneurysmal disease (CAAD), standard treatment options may not be suitable due to high thrombus burden, perioperative risk and factors unique to each patient. Thus, STEMI management in CAAD can represent a therapeutically challenging clinical scenario. Here, we describe a patient with severe three-vessel CAAD complicated by multivessel thrombosis and cardiogenic shock for whom traditional management options including placement of haemodynamic support devices were not feasible. As an alternative measure, the patient was treated with intracoronary thrombolysis with remarkable clinical stabilisation and angiographic resolution of thrombosis. He remains clinically stable several years later without recurrent events. This case serves to demonstrate the potential lifesaving benefit of intracoronary thrombolysis in complicated multivessel CAAD.

A right coronary artery saccular aneurysm leading to an embolic myocardial infarction during diagnostic cardiac catheterization: A case report

Coronary artery aneurysms are localized dilatations greater than 1.5 times the diameter of the adjacent segments. These rarely seen abnormalities may lead to serious life-threatening complications such as myocardial infarction, coronary perforation and death. Here, we present a case of periprocedural thromboembolic inferior myocardial infarction arising from a proximal right coronary artery saccular aneurysm during a diagnostic coronary angiography in a stable 70-year-old patient.
