“…In one case series that spanned over 10 years they reported five cases of coronary embolization, including one case secondary to a left atrial myxoma embolus [ 1 ]. In cases of an embolus secondary to a thrombus, patients often undergo a combination of interventions including systemic anticoagulation, coronary wiring and conventional aspiration thrombectomy devices [ 8 - 10 ]. Cases of acute coronary syndrome secondary to septic embolus from intracardiac infected valves have been managed with combined aspiration thrombectomy and coronary stenting [ 11 , 12 ].…”

Cardiac myxoma is the most common primary cardiac tumor. Rarely it can present with systemic or coronary embolization due to fragmentation of the tumor mass. We present a case of a young male who presented with an acute myocardial ischemia secondary to embolization of a left atrial myxoma originating from the left atrium. The patient underwent successful emergency surgical management of both the myxoma and the occlusion of the coronary artery. In this scenario, the surgery is the only effective treatment. The case also highlights the significance of performing emergency echocardiography in the setting of acute myocardial ischemia to look for possible associated pathology which can inform management plan.

“…Coronary embolism (CE) is more frequently reported in infective endocarditis patients and it mainly involves the left main coronary artery system due to flow characteristics and aortic morphology [4,5]. CE may also originate from mural thrombus within the left-sided cardiac chambers, but it has rarely been reported in the literature [6]. Most cases of coronary embolism in the literature have been reported secondary to infective endocarditis, valvular heart diseases, and atrial fibrillation [7][8][9].…”

Myocardial infarction with nonobstructive coronary artery disease (MINOCA) is a group of conditions that share common characteristics and is characterized by the absence of [?]50% stenosis of coronary arteries and without any evidence of atherosclerotic plaque rupture [1]. A study conducted by Waller et al. reported that 4% to 7% of all patients diagnosed with AMI, do not have underlying atherosclerotic coronary disease on autopsy or angiography [2].Coronary artery embolism is a rare and important non-atherosclerotic cause of acute myocardial infarction (AMI), and the first case of AMI secondary to coronary embolism was reported in 1856 by Rudolf Virchow and was classified initially as a precipitating factor for type-II MI, now recognized as one of the cause of MINOCA [3]. Coronary embolism (CE) is more frequently reported in infective endocarditis patients and it mainly involves the left main coronary artery system due to flow characteristics and aortic morphology [4,5]. CE may also originate from mural thrombus within the left-sided cardiac chambers, but it has rarely been reported in the literature [6]. Most cases of coronary embolism in the literature have been reported secondary to infective endocarditis, valvular heart diseases, and atrial fibrillation [7][8][9]. Here, we are reporting a case of a 74-year-old female, who had a chronic history of atrial fibrillation on anticoagulation with questionable compliance and was admitted with sepsis and takotasubo cardiomyopathy and later developed AMI secondary to coronary embolism to the left anterior descending artery. Case History/examination:A 74-year-old female with a past medical history of atrial fibrillation on rivaroxaban with questionable compliance, type 2 diabetes, multiple cerebrovascular accidents, and suspected paranoid schizophrenia, was brought to the ED with altered mental status.On examination, her pulse was 114/min, irregularly irregular, blood pressure of 123/109 mmHg, respiratory rate of 24/min, afebrile, and was maintaining oxygen saturation of 95% at room air. Methods:Baseline investigations showed WBC of 14.9 and urinalysis suggestive of UTI. Her Troponin level and proBNP were reported high (troponin 56 and proBNP of 16, 484). Electrocardiography (EKG) revealed atrial fibrillation with rapid ventricular response, low voltage QRS, poor R wave progression, and non-specific T wave

Coronary embolism is a cause of acute myocardial infarction (AMI)in which obstructive foci enter the coronary circulation, block normal blood flow and precipitate ischemia. Precise studies focusing on patient population affected, pathophysiological mechanisms, and treatment strategies are scanty, in spite of a reported prevalence estimated at 2.9%. As the understanding of myocardial infarction without evidence of coronary artery disease continues to grow, an in-depth review of this previously seldomly reported subtype of coronary ischemia was in order. Patients suffering coronary embolism are 15 to 20 years younger than traditional AMI patients with a slight predominance towards male sex, which resembles the gender data of the populations affected by non-traditional myocardial infarction in published reports. While the expected prevalence rate of cardiovascular disease risk factors such as hypertension and hyperlipidemia are present, this population also has a relatively high prevalence of atrial fibrillation and valve pathology, especially endocarditis. Initial presentation is indistinguishable from other causes of myocardial infarction however fever is commonly present, when endocarditis with valvular involvement is the primary cause of the coronary embolism. Mechanical thrombectomy is the mainstay of treatment, followed by percutaneous coronary intervention. Mortality is the highest in patients who do not receive targeted treatment for the coronary embolism, particularly if only antimicrobial agents or anticoagulation without thrombolytic agents are employed. The unique features of coronary embolism highlighted in this historical study justify further examination in contemporary patient populations.
