In the previous literature, the prevalence of right atrial (RA) clot‐in‐transit associated with pulmonary embolism is around 4–18% with an associated mortality of 80–100% in untreated cases. Surgical thrombo‐embolectomy has been the mainstay of treatment for stable patients but the data for percutaneous thrombo‐embolectomy is lacking in the literature. We present a series of three cases of right atrium clot‐in‐transit treated with catheter‐based therapies with Inari FlowTriever® (Inari Medical, Irvine, CA). Our three patients had different clinical profiles and presentations of right atrial clot‐in‐transit. All of the subjects had contraindications to surgical thrombo‐embolectomy and thrombolytic therapy. Catheter based embolectomy using Inari FlowTriever® was successfully performed in all the patients. As the data on this intervention is sparse, our case series highlights successful catheter based thrombo‐embolectomies in high‐risk individuals with right atrial clot in‐transit with or without pulmonary embolism.

Thyroiditis is characterised by transient hyperthyroidism, followed sometimes by hypothyroidism, and then recovery. We report a case of painless drug-induced thyroiditis-in a patient with no history of any thyroid disorder-treated with Nivolumab (an IgG4 monoclonal antibody against Programmed Death Receptor 1). The purpose of this case report is to increase awareness among clinicians regarding this possible adverse effect from Nivolumab, and discuss the possible pathophysiology and management strategies in such patients.
