Overview
Right main coronary artery thrombosis is a severe complication characterized by the formation of a thrombus within the right coronary artery, often leading to acute coronary syndrome and potentially life-threatening arrhythmias or infarction, particularly affecting the right ventricle 1.Diagnosis
Incidental discovery during imaging for other conditions
Echocardiography and transthoracic echocardiography (TTE) for thrombus visualization
Coronary angiography to confirm location and extent of thrombosis
Elevated biomarkers indicative of myocardial injury (Troponin levels) 1Management
First-line: Expectant management with close monitoring in stable patients 1
Adjunctive treatments: Anticoagulation with heparin or low molecular weight heparin (LMWH) to prevent further thrombus propagation 1
Specific drug classes: Consider initiation of antiplatelet therapy (e.g., aspirin) in conjunction with anticoagulation 1Special Populations
Comorbidities: Patients with coagulopathies or those with peritoneovenous shunts may have increased risk; management may require tailored anticoagulation strategies 1Key Recommendations
Monitor closely and consider expectant management in stable patients with right ventricular thrombus [Evidence: Expert opinion] 1
Initiate anticoagulation therapy with heparin or LMWH to manage thrombus [Evidence: Expert opinion] 1
Adjunctively use antiplatelet agents like aspirin to enhance antithrombotic effect [Evidence: Expert opinion] 1References
