“…This phenomenon is rare accounting for less than 2% of all arterial embolism [ 1 ]. Its consequences span from stroke [ 2 ], to mesenteric artery embolism [ 3 ], brachial artery embolism, kidney infarction [ 4 ], and in certain instances, even myocardial infarction [ 5 ]. The embolus typically comprises a blood clot, although it may be air, a tumor, or a particle of fat.…”

Background Paradoxical embolism is a rare cause of acute arterial occlusion. This phenomenon arises when embolic material travels from the venous system crosses an abnormal shunt such as patent foramen ovale, atrial septal defects, ventricular septal defects, or pulmonary arteriovenous malformations, into the arterial system. Impending paradoxical embolism refers to the presence of an entrapped thrombus in the patent foramen ovale. Case presentation We report a case of a 68-year-old female patient who presented with an impending paradoxical embolism, alongside both concomitant pulmonary embolism and myocardial infarction with ST-segment elevation. Swiftly addressed through emergency cardiac surgery and systemic anticoagulation, the patient’s condition was effectively treated. Conclusions While the ideal treatment strategy for impending paradoxical embolism remains a topic of debate due to limited and inconclusive evidence, emergent open surgery should be contemplated in patients as it signifies a critical clinical emergency.

A patent foramen ovale (PFO) is a fairly common mild cardiac defect that causes a shunting across the atrial septum. PFO is also a known risk factor for cryptogenic stroke. Much less frequently, PFO is associated with non-cerebral systemic embolic events. The article describes a case series of paradoxical embolism of the coronary arteries (CA), which caused myocardial infarction (MI). The presence of PFO was confirmed by imaging techniques. Subsequently, the patients underwent successful endovascular closure of the PFO. Thus, paradoxical CA embolism is a rare and underdiagnosed cause of acute MI. It should be considered in patients with MI and a low risk of atherosclerotic coronary artery disease. However, in most cases, it is not possible to verify the source of the embolism. The significance of occluder implantation as one of the treatment tactics requires further clarification.
