BACKGROUND: The majority of acute myocardial infarction (AMI) events are caused by thrombotic occlusion of the coronary artery, secondary to atherosclerotic plaque erosion or rupture. However, coronary embolism (CE), while rare, is being increasingly recognized as an important cause of AMI. We present the case of a patient with multi-site coronary artery embolization associated with hyperthyroid-related cardiomyopathy and atrial fibrillation. CASE PRESENTATION: A 49-year-old female with a history of hyperthyroidism and atrial fibrillation (AF) was admitted to our hospital presenting with right upper limb pain and swelling...

BACKGROUND AND AIM OF THE STUDY: Left ventricular (LV) distention, a recognized complication in patients supported with veno-arterial extracorporeal membrane oxygenation (VA-ECMO) for refractory cardiogenic shock, can lead to pulmonary edema, increased myocardial oxygen consumption, and LV thrombus formation. Atrial septostomy was examined as a management strategy for LV distension. METHODS: Of 72 patients supported with VA-ECMO, seven patients underwent atrial septostomy through a trans-septal approach...

OBJECTIVE: Pulmonary embolism (PE) is a common diagnosis with significant mortality if not appropriately treated. The use of transthoracic echocardiography in patients with PE is common; however, its diagnostic capabilities in this use are unclear. With the increased use of ultrasonography in medical settings, it is important to understand the strengths and limitations of echocardiography for the diagnosis of PE. METHODS: We conducted a systematic review of PubMed, CINAHL, and EMBASE through 2016 for articles assessing the diagnostic accuracy of transthoracic echocardiography for PE...

Patients with mechanical aortic valves are generally contraindicated for left ventricular assist device (LVAD) insertion because the prosthetic valve often becomes fixed in closed position. A 41-year-old woman with mechanical aortic valve prosthesis experienced sudden chest pain and developed cardiogenic shock. A paracorporeal pulsatile LVAD and a monopivot centrifugal pump as a right VAD (RVAD) were implanted. The mechanical aortic valve was intentionally left in place. Soon after the operation, LVAD support was discontinued daily for few seconds to allow the mechanical aortic valve to open and to avoid thrombus formation...

Aluminium phosphide (ALP) is widely used as a fumigant pesticide. In case of ALP poisoning, it is responsible for myocardial dysfunction, related to toxic myocarditis, and hemodynamic disorders. We report a case of a 28-year-old female who had intentionally ingested ALP and was admitted with cardiogenic shock. The transthoracic echocardiography (TTE) at the time of admission showed severe global myocardial hypokinesia with the presence of a giant left ventricular thrombus. Cardiovascular magnetic resonance (CMR) revealed extensive toxic myocarditis with a left ventricular systolic dysfunction...

OBJECTIVES: Aortic valve bypass (AVB) (apico-aortic conduit) remains an effective surgical alternative for patients in whom surgical aortic valve replacement or transcatheter aortic valve implantation is not feasible. However, specific complications include thrombus formation, possibly caused by stagnation arising from flow competition between the antegrade and retrograde flow, but this has not been fully investigated. The aim of this study was to analyse flow characteristics after AVB and to elucidate mechanisms of intra-aortic thrombus using computational fluid dynamics (CFD)...

A 69 year old male, an ex-smoker, was admitted with ongoing chest pain of 11 hours duration. Past medical history included treated hypertension and gastro-oesophageal reflux disease. He delayed seeking medical attention as he assumed the pain to be due to indigestion and kept taking antacids without much symptomatic relief. Clinical examination on arrival was unremarkable. Admission 12 lead electrocardiogram (ECG) was diagnostic of a recent anterolateral myocardial infarction (MI) (Figure 1a). Bedside trans-thoracic echocardiogram (TTE) confirmed an established anterolateral MI (Video 1, Figure 1b)...

We encountered a 45-year-old Japanese man who suffered from pulmonary thromboembolism and huge right ventricular thrombus after inferior vena cava (IVC) filter implantation without apparent thrombus in either the deep veins or inside the IVC filter. The biochemical data showed a discrepancy in the level of fibrinogen between the immunological and thrombin time methods, suggesting hypodysfibrinogenemia. The sequencing of the fibrinogen γ-chain gene (FGG) revealed a novel heterozygous missense mutation in exon 8 - a TGT to TCT transversion in codon 326 - resulting in an amino acid substitution of serine for cysteine (γCys326Ser)...

Kounis syndrome is the concurrence of coronary spasm, acute myocardial infarction or stent thrombosis, with allergic reactions in the setting of mast-cell and platelet activation. In this report Kounis syndrome manifesting as stent thrombosis with left ventricular thrombus formation was triggered by a food-induced allergic reaction. The allergic reaction to food was confirmed by oral rice pudding ingredients challenge test while skin tests were inconclusive. To our knowledge, this is first report of early stent thrombosis secondary to food allergic reaction in a 70-year-old man patient who was found to have left ventricular thrombus and undiagnosed hypertrophic cardiomyopathy...

BACKGROUND: Saphenous vein graft thrombosis can present as unstable angina. However, percutaneous coronary intervention for saphenous vein graft lesions poses a high risk of slow flow related to the procedure. Here we present the utilization of the novel oral anticoagulant, apixaban, in the treatment of unstable angina with extensive saphenous vein graft thrombus, leading to considerable thrombus resolution and eliminating the need of percutaneous coronary intervention. CASE PRESENTATION: A 72-year-old man with 3-vessel coronary artery bypass graft surgery using a saphenous vein graft and a left internal mammary artery, performed 25 years earlier, presented at our hospital with recurrent chest tightness...
