Background: Septic embolism is a relatively common and potentially severe complication of infective endocarditis (IE), and most often are found in the brain, solid organs (e.g. spleen, kidney, lungs), and lower extremity. Interestingly, we found an acute venous thromboembolic event in IE patient with septicemia. Case illustration: A 42-year-old male was referred from neighboring island to our hospital for IE and septic shock. On admission he complained of shortness of breath during heavy activity, with fatigue and fever for seven days. He also presented with acute onset of left upper extremity pain for three days. The pain was increased over time with burning sensation, exacerbated by activity, and there were no relieving factors. The left upper extremity looks bluish with bruising, accompanied by tenderness, and warm to touch. Laboratory examination showed leukocytosis (24.7 × 10⁹/L), thrombocytopenia (65 × 10⁹/L), elevated transaminase (SGOT 3.920 and SGPT 1.836), elevated serum creatinine (4.1 mg/dL), with an elevated infection marker (CRP 5.42 mg/L and procalcitonin 1.03 μg/L). Echocardiography showed severe mitral regurgitation (MR) with
