Percutaneous thrombectomy and right ventricular mechanical circulatory support for pulmonary embolism in a coronavirus disease 2019 patient: case report, 1-year update, and echocardiographic findings

BACKGROUND: We previously described percutaneous thrombectomy and right ventricular (RV) mechanical support of a coronavirus disease 2019 (COVID-19) patient with a massive pulmonary embolism. Here, we present a detailed echocardiographic and clinical timeline with 1-year follow-up. CASE SUMMARY: A 57-year-old female with COVID-19 went into shock from a massive pulmonary embolism. After percutaneous removal of a large thrombus burden (AngioVac system; AngioDynamics Inc., Latham, NY, USA), she became severely hypotensive, requiring cardiopulmonary resuscitation, and hemodynamic support with an Impella RP device (Abiomed, Danvers, MA, USA). A paediatric transoesophageal echocardiography (TOE) probe monitored the procedure because an adult probe would not pass (S7-3t—Philips Medical Systems, Andover, MA, USA). Post-thrombectomy, surface imaging documented gradual resolution of RV dysfunction, tricuspid regurgitation, and elevated pulmonary artery pressure. Her course was complicated by renal failure requiring temporary dialysis. She was discharged home on apixaban. Hypercoagulability work-up was negative. Two months later, vocal cord surgery was performed for persistent stridor. Esophagoscopy at that time was prevented by osteophyte obstruction. At 10 months, she received the Pfizer-BioNTech vaccine. At 1 year, the patient remains healthy on apixaban, and her echocardiogram is normal. DISCUSSION: This case illustrates the pivotal role of echocardiography in the diagnosis, percutaneous treatment, and near- and long-term follow-up and management of a patient with massive pulmonary embolism due to COVID-19 with documentation of complete recovery from severe RV dysfunction and haemodynamic collapse. A paediatric TOE probe was a crucial alternative to the adult probe because of possible osteophyte obstruction.
