A 40-year-old male tobacco chewer presented with complaints of left lower limb pain for 4 days. On examination, he had swelling in his left lower limb and ECG showed signs of right ventricular strain. Echocardiogram revealed an enlarged right ventricle and atrium with moderate tricuspid regurgitation and reduced right ventricular function. Given his risk factors and test results, the patient is at intermediate-low risk for pulmonary embolism. A CTPA was planned to confirm, anticoagulation was started, and oral anticoagulation was recommended for 6 months with follow up in 3 months to assess right ventricular function and risk of chronic thromboembolic pulmonary hypertension.
