Right atrial thrombus, junctional tachycardia, and critical lower limb ischemia: three rare complications of severe acute respiratory syndrome coronavirus 2 infection

Abstract

Severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) infection can engender multi-system inflammatory syndrome. Its main symptoms are cardiovascular and thromboembolic problems that can develop into severe complications. The present case is about a 55-year-old patient who was admitted for critical ischemia of the right lower limb and necrosis of the right forefoot. The patient was infected with coronavirus disease 2019 (COVID-19) one month before her admission. The patient also has cardiovascular risks including type 2 diabetes and hypertension. The performance of ultrasounds revealed a thrombus in the right atrium and the pulmonary artery, and arteriography detected an occlusion of the right popliteal joint for which she had an endovascular recanalization and amputation of the right forefoot. This case highlights that SARS-CoV-2 infection could be considered a serious cardiovascular disease requiring cardiovascular explorations to initiate hospital management and avoid severe complications.
