Additional Document Info
We report an extremely rare case of an extensive biatrial thrombus straddling a patent foramen ovale (PFO) extending into the bilateral ventricles in a patient presenting with an acute embolic stroke. Our patient further developed a massive saddle pulmonary embolus (PE) with haemodynamic instability during the course of his hospitalisation. The risks of pharmacological thrombolysis or surgical thrombectomy for PE in a haemodynamically unstable patient with recent embolic stroke posed a significant therapeutic dilemma. Ultimately, the decision was made to continue anticoagulation with unfractionated heparin followed by oral Coumadin. The patient responded well to therapy and at 1-month follow-up, a complete resolution of the thrombus was documented on transoesophageal echocardiogram with full clinical recovery of the patient.2016 BMJ Publishing Group Ltd.
