Abstract

PEREZ-CERVERA, Javier et al. Pulmonary embolism and embolic myocardial infarction in a patient with thrombi in transit through a patent foramen ovale. Rev. Colomb. Cardiol. [online]. 2021, vol.28, n.6, pp.639-641.  Epub Jan 07, 2022. ISSN 0120-5633.  https://doi.org/10.24875/rccar.m21000106.

The authors describe a case of a patient admitted with ST elevation myocardial infarction. An emergent coronariography was done, showing a thrombus in the right coronary artery, without evidence of atherosclerotic lesions in the coronary bed. Due to this, she is diagnosed with probable embolic myocardial infarction. When she was performed a transthoracic echocardiography, the presence of free thrombi was detected in right and left chambers of the heart. Due to this, a CT angiography with pulmonary embolism protocol was done, confirming the presence of a massive bilateral pulmonary embolism. After that, a new trans-thoracic echocardiography was done, finding an aneurism at interatrial septum, with an apparent protrusion of thrombotic mass through it. The decision taken was initiating therapeutic anticoagulation, having the patient a positive evolution with disappearance of thrombi in the bubble test performed days later, and showing the presence of a patent foramen ovale. The purpose of the presentation of this case report is, firstly, illustrating an entity which in very few occasions can be demonstrated by imaging tests, and secondly, making a brief review of the diagnosis and management of the patent foramen ovale as a part of the study of embolic sources.
