Relevant Clinical History and Physical Exam

We present a 25 year old man with no known medical illness, who presented with chest discomfort and shortness of breath for the past 3 days. He was a heavy smoker, with family history of ischemic heart disease. Upon arrival to the emergency department, he was tachypneic with respiratory rate of 24 breaths per minute. His blood pressure was 105/60 mm Hg, with pulse rate of 95 beats per minute. On examination, his lungs were clear and CVS examination was unremarkable. 

Relevant Test Results Prior to Catheterization

Initial ECG showed subtle ST elevation over inferior leads. However bedside echocardiography showed dilated right ventricle with D-shaped LV suspicious of acute pulmonary hypertension. Laboratory investigation showed elevated troponin of 139.5 pg/ml. Initial chest x-ray showed prominent pulmonary trunk with borderline cardiomegaly. Patient was subsequently treated for acute coronary syndrome with dual antiplatelet and parenteral anticoagulant. 

Relevant Catheterization Findings

However, he soon developed hypotension and was intubated for impending respiratory collapse. CT pulmonary angiography showed extensive bilateral pulmonary embolism, with multiple hilar lymphadenopathy. As he was hemodynamically unstable, decision for percutaneous pulmonary intervention was made. 

Interventional Management

Procedural Step

Vascular access was done over right femoral vein with an 8F sheath. Diagnostic pulmonary angiography with a pigtail catheter confirmed bilateral PE with left worse than right, with PA mean pressure of 45 mm Hg. Catheter aspiration with PENUMBRA device was done over 3 runs over the left PA. A total of 1 liter blood loss was recorded. However patient remained hemodynamically stable. About 60 cc of blood clot was evacuated. Post procedure left pulmonary angiography showed improved pulmonary perfusion. Final mean PA pressure of 30 mm Hg was documented at the end of procedure. Patient then transferred to the coronary care unit for further observation with intravenous heparin infusion.

Case Summary

The next day, patient was extubated with good oxygen saturation. On further laboratory testing, his B-HCG was elevated, and he was diagnosed as non-seminoma germ cell tumor by the oncology team, and was started on chemotherapy. He was discharged after 2 weeks post intervention, and was seen at our clinic a month after in which he was given direct oral anticoagulant for at least 3 months. Repeated echocardiography showed normal cardiac chambers with no features of pulmonary hypertension.This case showed how acute pulmonary embolism may mimic acute coronary syndrome especially from the ECG and cardiac enzymes parameters. Percutaneous intervention helped to save the patient.
